3 New Findings on AFib and What They Mean

3 New Findings on AFib and What They Mean

Comments 0 Comment

If you’re among the 1 in 5 U.S. adults who have an abnormal heart rhythm problem called atrial fibrillation, there’s been a flurry of new research about the condition that offers some guidance on your everyday choices and how those impact your risk of recurrence.

“The major risk is stroke, and preventing stroke is the name of the game with AFib.
Three new studies shed light on some common questions: whether your morning coffee matters, whether a diabetes drug might help lower recurrence risk, and what new data reveals about AFib’s link to dementia.

Here’s what the latest research suggests:
Coffee doesn’t increase the risk of recurrent atrial fibrillation. A small but well-designed new study showed that people who drank a cup of coffee daily were not more likely than non-coffee drinkers to have a repeat atrial fibrillation episode after successful treatment with electrical cardioversion – a quick procedure where a doctor delivers a brief, controlled shock to the heart to put it back into a normal rhythm. People in the study agreed ahead of time to be randomly assigned to one of two groups: those who continued drinking coffee as they did before the study, and those who abstained for six months.

Why it matters: Many people and even some doctors still assume coffee triggers AFib, a long-held bit of “common wisdom” that isn’t backed by strong evidence, Prystowsky said. It’s a top concern for newly diagnosed patients, but experts say coffee is rarely a problem except in people with palpitations. The design of this latest study, randomizing people before asking them to keep drinking or abstain, makes the results particularly trustworthy, he said.

What you can do: If you’re going to change one beverage you consume to manage atrial fibrillation risk, go ahead and keep drinking coffee and instead focus on reducing or cutting out alcohol.

Metformin helped reduce AFib recurrence in a small study of people with overweight and obesity. In a study of 99 people with overweight or obesity who had an ablation procedure, where doctors burn or freeze tiny areas of heart tissue to stop the abnormal signals that cause AFib, those who took the type 2 diabetes drug metformin after ablation were less likely to have recurrent AFib. None of the people in the study had diabetes, although 40% of them met prediabetic blood sugar criteria. The study was presented at an American Heart Association conference this month and hasn’t been published in a peer-reviewed journal.

Why it matters: Doctors are talking about this study because it’s another step toward understanding the connection between weight and AFib risk. An important previous study showed that people who lost 10% of their body weight were six times more likely to survive four years without recurrence. “It wasn’t just weight loss, though,” Prystowsky said, noting that those who lost weight had improved glucose and blood pressure levels.
Interestingly, in this latest metformin study, people saw AFib benefits without significant weight loss. That suggests the drug may be affecting the body in other ways, possibly through metabolism, inflammation, or fat around the heart, though researchers don’t yet know the exact mechanism, Prystowsky said.

What you can do: “The most important takeaway from this small study is reinforcing the idea that the management of obesity makes a huge difference in outcomes for atrial fibrillation,” Philbin said. He and Prystowsky agreed the study was too small for a doctor to recommend that a patient take metformin to reduce AFib risk, though. The study was “hypothesis-forming rather than game-changing, but it reinforces some ideas we know about atrial fibrillation that we know will work: you should exercise. You should lose weight. You should not drink alcohol,” Philbin said. He and his colleagues plan to explore whether AFib patients benefit from six weeks of supervised exercise and dietitian guidance the way heart attack survivors do.

Another study just linked AFib with dementia risk. Published this month in JACC: Advances, the analysis looked at 670,745 Medicare patients 65 and older and found that those who developed AFib after non-cardiac surgery were more likely to later be diagnosed with dementia. In cardiac surgery patients, dementia rates were similar regardless of AFib (about 4%). But after non-cardiac surgery, dementia was diagnosed in nearly 13% of people with AFib, versus 9% without – a 20% increased risk. Non-cardiac procedures ranged widely, with orthopedic (including joint replacements), gastrointestinal, and circulatory surgeries most common.

Why it matters: The study authors wrote it was “notable” that cardiac surgery patients who developed AFib weren’t more likely to get dementia, suggesting their AFib may have been triggered by the surgery itself. They couldn’t explain why non-cardiac surgery patients had a higher dementia risk and found no clear contributing factors like high blood pressure, diabetes, or prior stroke or heart failure. They hypothesized that undetected mild strokes or heart attacks, which can damage the brain and blood vessels, might play a role. The link between AFib and dementia is established, and while silent strokes and heart attacks are suspected contributors, the data shows a link rather than a cause. Prystowsky tells patients who get AFib after non-cardiac surgery that they have a higher risk of recurrence and need to be aware of it.

What you can do: If you’re heading into surgery, worrying about AFib shouldn’t be at the top of your list, Prystowsky said. But if you like to be prepared, both Philbin and Prystowsky advised that wearing a device like a smartwatch that can check your pulse and rhythm can help you spot any issues early. And if you’ve already had AFib after a non-cardiac surgery, regular monitoring is especially important – and you should call your doctor if your device flags an abnormal pulse or rhythm.

Metformin may weaken cardiovascular, insulin benefits of exercise…

Metformin may weaken cardiovascular, insulin benefits of exercise…

Comments 0 Comment

This is a fascinating and nuanced topic that sits at the intersection of two foundational treatments for type 2 diabetes. The headline is based on real research, but it requires important context to be fully understood. Here’s a breakdown of what the science says, what it means, and who should be concerned.

The Core Finding: The “Metformin-Exercise Interaction”

The claim originates primarily from a series of studies, most notably a 2013 randomized controlled trial published in The Journal of Clinical Endocrinology & Metabolism and other follow-up research.

The studies found that in older, overweight, or pre-diabetic adults, taking metformin seemed to blunt some of the key physiological benefits of exercise compared to a placebo group that did the same exercise regimen.

The blunted benefits were specifically in two areas:

  1. Insulin Sensitivity: Exercise is one of the most powerful ways to improve insulin sensitivity. The studies found that the group taking metformin saw a significantly smaller improvement in insulin sensitivity from their exercise training than the placebo group.
  2. Mitochondrial Function: Exercise trains your muscles’ mitochondria (the cellular power plants) to become more efficient and numerous. The metformin group showed a reduced improvement in markers of mitochondrial health.

The proposed mechanism is that metformin and exercise act on the same pathway, but in somewhat opposing ways.

  • Exercise signals through AMPK (AMP-activated protein kinase), a cellular energy sensor. When you exercise, you deplete energy, activating AMPK. This tells the cell to ramp up energy production (improve mitochondria) and increase glucose uptake (improve insulin sensitivity).
  • Metformin also works primarily by activating AMPK.

The theory is that by chronically activating AMPK pharmacologically, metformin might “pre-empt” or dull the cell’s robust response to the natural AMPK signal from exercise. It’s as if the cell is already being “shouted at” by the drug, so it doesn’t “hear” the shout from exercise as clearly.

Crucial Context and Limitations

This is where the “may” in the headline becomes critically important. This interaction is not a universal rule and has several important caveats:

  • Population Specific: The effect has been most consistently observed in at-risk, non-diabetic individuals (e.g., those with pre-diabetes or insulin resistance) and older, overweight populations. The evidence is much less clear for people with established type 2 diabetes.
  • Benefit Blunting vs. Benefit Elimination: The studies show a reduction in the improvement, not a complete elimination. The metformin+exercise group still saw benefits—just not as much as the exercise-only group.
  • Cardiovascular Benefits Are Broader: The term “cardiovascular benefits” can be misleading. While mitochondrial and insulin-sensitivity improvements are crucial for metabolic cardiovascular health, exercise provides a host of other cardiovascular benefits that are likely NOT blunted by metformin, such as:
    • Lowering blood pressure
    • Improving cholesterol levels
    • Strengthening the heart muscle
    • Improving endothelial function (blood vessel health)
    • aiding in weight management

What This Means For You: Practical Takeaways

  1. For People with Type 2 Diabetes: Do NOT stop taking metformin. For you, the proven, powerful benefits of metformin in controlling blood glucose and reducing the risk of diabetes complications far outweigh the potential slight blunting of exercise’s effect on insulin sensitivity. The combination of metformin and exercise is still a cornerstone of effective diabetes management.
  2. For People with Pre-Diabetes: This is the group where the conversation is most relevant. If you are using exercise as your primary tool to prevent the onset of type 2 diabetes, it’s worth having a discussion with your doctor. They might consider whether lifestyle intervention alone is sufficient before adding metformin. However, for many, the combination is still recommended as the most effective strategy.
  3. For Healthy Individuals or Athletes: This research is likely not relevant to you. Metformin is not prescribed for this population, and the studies did not involve them.
  4. The Overarching Principle: Exercise is Non-Negotiable. Regardless of whether you take metformin, exercise remains one of the most powerful health interventions available. Its benefits extend far beyond the specific metrics that might be slightly blunted. The worst decision you could make based on this research is to stop exercising.

Conclusion

The statement “Metformin may weaken cardiovascular, insulin benefits of exercise” is scientifically accurate but easily misinterpreted.

  • The Science: It appears that metformin can attenuate some of the specific cellular and metabolic adaptations to exercise, particularly improvements in insulin sensitivity and mitochondrial biogenesis, likely through competing actions on the AMPK pathway.
  • The Reality: For the vast majority of people taking metformin (especially those with type 2 diabetes), this potential interaction is a minor consideration. The powerful, combined benefits of both the medication and physical activity make them a winning combination for long-term health.

Always consult your doctor before making any changes to your medication or exercise regimen. They can provide personalized advice based on your specific health status and goals.

Blood vessels in eyes may help predict heart disease and biological aging risk.

Blood vessels in eyes may help predict heart disease and biological aging risk.

Comments 0 Comment

That’s a fascinating and accurate insight. This field of research is growing rapidly and holds significant promise for non-invasive health diagnostics.
Here’s a detailed breakdown of how the blood vessels in your eyes (the retina) can serve as a window to your heart health and biological age.

Why the Retina is a Unique “Window”
The retina is the only place in the body where you can directly and non-invasively view microvascular blood vessels (arterioles and venules). These tiny vessels are sensitive to the same pressures and damage that affect the entire circulatory system, including the heart and brain. Changes in their structure and function often mirror what’s happening in vessels you can’t see.

  1. Predicting Heart Disease Risk
    The condition of the retinal vessels, known as Retinal Vascular Caliber, is a key indicator.

What Doctors Look For:
Narrowing of Arterioles: This is a classic sign of hypertension (high blood pressure). The constant high pressure causes the vessel walls to thicken, making the central light reflex (the visible column of blood) appear narrower.

Arteriovenous (AV) Nicking: This occurs when a hardened retinal artery compresses a vein where they cross, causing the vein to appear “nicked” or pinched. It’s a sign of chronic hypertension and advanced vascular damage.

Microaneurysms, Hemorrhages, and Cotton-Wool Spots: These are signs of more severe damage, often seen in diabetic retinopathy and hypertensive retinopathy. Since diabetes is a major risk factor for heart disease, these findings are a red flag for systemic cardiovascular issues.

The Link to Heart Disease:
The same processes that damage retinal vessels—inflammation, oxidative stress, and endothelial dysfunction also damage the coronary arteries supplying the heart.

Studies have shown that people with narrower retinal arterioles and wider venules have a higher risk of developing hypertension, coronary heart disease, heart failure, and stroke, even after accounting for traditional risk factors like smoking and cholesterol.

  1. Predicting Biological Aging Risk
    This is an even more cutting-edge application. The concept is that the “age” of your retinal vessels may be a better indicator of your overall health and mortality risk than your chronological age.

Retinal Age Gap: Researchers are using advanced AI to analyze retinal images and predict a person’s “biological age” based on the health of their retinal vasculature. How it works: A deep learning model is trained on thousands of retinal images from healthy people to learn what a “normal” retina looks like at different chronological ages.

The Key Finding: People whose retinas look “older” than their actual age (a positive “retinal age gap”) have a significantly higher risk of death from all causes, and specifically from cardiovascular disease. A large study found that every 1-year increase in the retinal age gap was associated with a 2-3% increase in all-cause and cause-specific mortality risk.

Why it Reflects Biological Aging:
The retina is part of the central nervous system (it’s an extension of the brain). Its health is closely linked to brain health. The microvasculature in the retina is sensitive to cumulative lifelong damage from factors like high blood pressure, high blood sugar, and oxidative stress—all key drivers of biological aging.

Therefore, an “aged” retina suggests accelerated aging and cumulative damage throughout the entire body’s vascular and neurological systems. The Future: AI and Routine Screening
The traditional method of a doctor manually examining the retina is being supercharged by Artificial Intelligence.

Automated Analysis: AI algorithms can now quickly and accurately measure retinal vessel caliber, detect lesions, and even calculate a “retinal age” from a simple, non-invasive photograph.

Potential for Widespread Use: Because retinal imaging is quick, cheap, and non-invasive, it has the potential to become a powerful tool for mass screening. A routine eye exam could one day provide a risk assessment for heart disease, stroke, and overall health, prompting earlier intervention.

The blood vessels in your eyes are far more than just tools for vision. They are a unique and accessible mirror of your body’s circulatory and neurological health. By examining them, doctors and AI can get an early, direct look at the silent damage caused by conditions like hypertension and diabetes, potentially predicting your risk for major heart events and even your rate of biological aging.

Disclaimer: This information is for educational purposes only. While retinal health is an exciting area of predictive medicine, it is not a standalone diagnostic tool. Always consult with your primary care physician and a cardiologist for a comprehensive assessment of your heart disease risk.

This is a fascinating and rapidly advancing area of research. The claim that blood vessels in the eyes can help predict heart disease and biological aging risk is strongly supported by scientific evidence.

Here’s a detailed breakdown of how it works, the science behind it, and what it means for the future.

The Window to Your Health: The Retina

The back of your eye, called the retina, is the only place in the body where doctors can directly and non-invasively view a network of tiny blood vessels (microvasculature) and nerves.

The health of these small vessels is a mirror of the health of similar-sized vessels throughout your body, including in your brain, heart, and kidneys. Damage to these microvessels is often a very early sign of systemic (whole-body) diseases.

1. Predicting Heart Disease (Cardiovascular Risk)

The link between the retina and heart disease primarily revolves around a condition known as Retinopathy.

How it Works:

  • Shared Physiology: The small vessels in your retina are similar in size, structure, and function to the small vessels that supply the heart muscle itself. Factors that damage one are likely to damage the other.
  • The Damage Process: Conditions like high blood pressure (hypertension) and atherosclerosis (clogging of the arteries) don’t just affect large arteries. They also cause:
    • Narrowing (Arteriolosclerosis): The retinal arteries become thicker and narrower.
    • AV Nicking: Where arteries cross over veins, they can compress them, a sign of chronic high blood pressure.
    • Hemorrhages & Microaneurysms: Weakened vessel walls can leak blood or form tiny bulges.
  • What Doctors Look For: An eye doctor (ophthalmologist) or even an AI algorithm analyzing a retinal image can identify these changes. Their presence is classified as Hypertensive Retinopathy or, if related to diabetes, Diabetic Retinopathy.

The Evidence:
Multiple large-scale studies have shown that people with these retinal changes have a significantly higher risk of:

  • Coronary heart disease
  • Heart failure
  • Stroke
  • Death from cardiovascular causes

Essentially, the retina acts as an “early warning system,” showing damage from high blood pressure and vascular disease long before a major cardiac event like a heart attack occurs.

2. Predicting Biological Aging Risk

This is an even more cutting-edge application. The concept is that the condition of your retinal vessels can reveal your “biological age” as opposed to your “chronological age.”

How it Works: Researchers use a metric called the “Retinal Age Gap.”

  1. Training an AI: Scientists train a sophisticated deep-learning algorithm on hundreds of thousands of retinal images from healthy people.
  2. Learning the Pattern: The AI learns what a “healthy” retina looks like at different chronological ages (e.g., age 40, 50, 60). It becomes an expert at predicting someone’s age just from their retinal scan.
  3. Calculating the Gap: The AI then analyzes a new person’s retina and gives a “retinal age” prediction. The difference between this predicted biological age and the person’s actual chronological age is the “Retinal Age Gap.”
    • Example: If the AI says your retina looks like that of a 50-year-old, but you are only 45, you have a +5-year Retinal Age Gap.

What the Research Shows:
A large study published in the British Journal of Ophthalmology found that:

  • A large Retinal Age Gap (e.g., your retina is “older” than you are) is significantly associated with a higher risk of death, particularly from cardiovascular disease.
  • This link remained strong even after accounting for traditional risk factors like age, smoking, and BMI.

Why is this a powerful indicator?
The retina is part of the central nervous system (it’s an extension of the brain). Its health is intimately tied to the overall health of your circulatory system and cellular aging processes. An “older” retina suggests accelerated aging and cumulative damage throughout the body’s vascular and neurological systems.

The Future: AI and Retinal Scans

This research is moving quickly from the lab to the clinic, powered by Artificial Intelligence (AI).

  • Automated Screening: AI can analyze a routine retinal photo in seconds, providing a quantitative and objective assessment of cardiovascular risk and biological age.
  • Accessibility: A quick, non-invasive retinal scan could become a standard part of a general health check-up, not just an eye exam, making advanced risk prediction more accessible.
  • Personalized Medicine: It could help doctors identify high-risk individuals earlier, allowing for more aggressive and personalized preventative strategies (like lifestyle changes and medications).

Limitations and Important Caveats

  1. It’s a Predictor, Not a Crystal Ball: A retinal scan is a powerful risk indicator, but it’s not a definitive diagnosis. It adds to the overall picture alongside blood tests, blood pressure readings, and family history.
  2. Still in Development: While the science is robust, the use of “retinal age” as a clinical tool is still being refined and validated.
  3. Cannot Replace Specific Tests: It won’t tell you your exact cholesterol levels or if a specific artery is blocked. It assesses the health of your microvasculature, which is a proxy for systemic health.

Conclusion

The idea that the blood vessels in your eyes can predict heart disease and biological aging is not science fiction; it’s solid science. Your retina provides a unique, real-time window into the health of your entire circulatory system and the pace of your body’s aging. With the help of AI, this “window” is poised to become a revolutionary tool in preventative medicine, helping people take control of their health long before serious problems arise.

D3 supplements could halve the risk of a second heart attack

D3 supplements could halve the risk of a second heart attack

Comments 0 Comment

That’s a very interesting and significant claim, and it’s based on emerging research. Let’s break down what the science currently says about this. The statement that “Vitamin D3 supplements could halve the risk of a second heart attack” is a simplified summary of the findings from a specific, and quite important, clinical trial.

The Key Study: The VITAL Rhythm Trial
The most direct evidence for this claim comes from a sub-study of the large-scale VITAL trial, published in 2020. What was the main VITAL trial? A major study investigating whether vitamin D3 (2000 IU/day) or omega-3 fatty acids could prevent heart attacks, strokes, and cancer in generally healthy adults. The main results were modest.

What did the VITAL Rhythm sub-study find? This part of the trial specifically looked at people who had a previous heart attack. They found that among these participants, those who took vitamin D3 had a significantly lower risk of having a subsequent major cardiovascular event, including a fatal heart attack. The risk reduction was indeed reported to be around 50%.

How Might Vitamin D Help the Heart?
The proposed mechanisms are biologically plausible:

Reducing Inflammation: Chronic inflammation is a key driver of atherosclerosis (hardening of the arteries). Vitamin D has anti-inflammatory properties.

Improving Vascular Function: Vitamin D may help the lining of blood vessels (the endothelium) function better, keeping them flexible and healthy.

Regulating Blood Pressure: It plays a role in the renin-angiotensin system, which helps control blood pressure.

Modulating Immune Response: It may help stabilize arterial plaques, making them less likely to rupture and cause a blockage.

Important Nuances and Caveats
While the findings are promising, it’s crucial to understand the context and limitations:

Not for Primary Prevention: The dramatic benefit was seen only in people who had already experienced a heart attack (this is called “secondary prevention”). For the general population without a history of heart attack, vitamin D supplementation has not shown a clear benefit in preventing a first heart attack.

Correlation is Not Causation (Yet): While this was a randomized controlled trial (the gold standard), more research is needed to confirm these results and firmly establish vitamin D as a standard secondary prevention therapy.

The “Baseline Level” Hypothesis: A leading theory is that the benefit is most pronounced in people who are deficient in vitamin D to begin with. Correcting a deficiency may be what’s driving the benefit, rather than supplementing in people who already have sufficient levels.

Dosage Matters: The study used a high dose (2000 IU/day). This should not be taken without considering one’s baseline levels and consulting a doctor.

Not a Magic Bullet: Vitamin D supplementation is not a substitute for proven heart attack prevention strategies, such as:
Statin medications
Blood pressure control
Aspirin or other antiplatelet drugs (as prescribed)
Smoking cessation
A healthy diet and regular exercise

What Should You Do?
Get Tested: If you have a history of heart disease or have had a heart attack, ask your doctor to check your 25-hydroxyvitamin D blood level. This is the only way to know your status.
Discuss with Your Doctor: Based on your test results and overall health, your doctor can determine if supplementation is right for you and what the appropriate dose would be.

Focus on a Comprehensive Plan: View vitamin D as a potential part of a comprehensive cardiac rehabilitation and prevention plan, not a standalone solution.

In summary, the claim is based on solid, recent research and is up-and-coming for a specific high-risk group, heart attack survivors. However, it is not a recommendation for the general public to start high-dose vitamin D supplementation for heart health, and it should always be implemented under the guidance of a medical professional.

A new randomized trial called TARGET-D (reported at the AHA Scientific Sessions 2025 and in Intermountain Health press materials) found that tailored vitamin D₃ supplementation, adjusting doses to reach and maintain target blood levels (≈40–80 ng/mL), was associated with about a 50% lower risk of a second heart attack in people who recently had a myocardial infarction. The result is promising but preliminary (abstract / press release), and it did not reduce the trial’s composite major-adverse-cardiac-event (MACE) endpoint. More peer-reviewed data are needed before changing practice.

Vitamin D has known effects on inflammation, vascular function, and the renin–angiotensin system; observational studies have linked low vitamin D to worse cardiovascular outcomes. Tailoring doses to achieve a biological target (instead of giving everyone the same pill) is a different strategy from many prior trials.

Past large randomized trials and meta-analyses generally did not find that unselected vitamin D supplementation prevents heart attacks or other major cardiovascular events. The new TARGET-D result is from an abstract/conference presentation and institutional press releases, promising but preliminary until a full peer-reviewed paper appears and the finding is replicated in other trials.

If you’ve had a heart attack, don’t change or start high-dose vitamin D on your own based on news alone. Discuss vitamin D testing and any supplementation with your cardiologist or primary care clinician. If you’ve had a heart attack, don’t change or start high-dose vitamin D on your own based on news alone. Discuss vitamin D testing and any supplementation with your cardiologist or primary care clinician.

The study used monitoring + individualized dosing (some people needed much higher daily intakes than typical OTC doses), so safety monitoring (blood 25-OH-D, calcium) matters if doses are high. Vitamin D toxicity is uncommon but can occur with very large, unmonitored doses.

This is an interesting and potentially important finding: targeted vitamin D₃ supplementation reduced recurrent MI risk in this single trial, but it is not yet definitive. Expect investigators to publish the full results, and for guideline-level changes to require replication and peer review. Until then, vitamin D testing and discussion with your clinician is the prudent route.

Long-term melatonin use linked to 90% greater heart failure risk.

Long-term melatonin use linked to 90% greater heart failure risk.

Comments 0 Comment

Approximately 16% of people worldwide suffer from insomnia. A person can enhance the quality of their sleep in a variety of ways, including by taking melatonin supplements. Previous research indicates that using melatonin supplements may pose certain risks. According to a recent study, taking melatonin supplements over an extended period of time may increase the risk of heart failure. According to research, 16% of people worldwide suffer from insomnia, which is the inability to fall or stay asleep. A person can enhance the quality of their sleep in a variety of ways. Among them are behavioral adjustments like maintaining proper sleep hygiene, exercising during the day, and avoiding certain foods right before bed. Other individuals who have trouble falling asleep may choose to use medical interventions, such as prescription drugs or over-the-counter remedies like melatonin supplements, a hormone that the body produces naturally and is crucial.

12-month or longer melatonin use linked to 90% greater heart failure risk
Researchers examined medical records from TriNetX for nearly 131,000 adults who had been diagnosed with insomnia, with an average age of roughly 56. Approximately 65,000 study participants reported taking melatonin for at least a year after receiving a prescription for it at least once. According to the study’s findings, individuals who took melatonin for longer than a year had a 90% higher risk of heart failure over five years than those who did not. Additionally, participants had an 82% higher risk of heart failure if they had filled at least two melatonin prescriptions at least ninety days apart. Furthermore, during the five-year follow-up period, researchers found that melatonin users were roughly 3.5 times more likely to be hospitalized for heart failure and twice as likely to die from any cause.

Melatonin supplements are widely thought of as a safe and ‘natural’ option to support better sleep, so it was striking to see such consistent and significant increases in serious health outcomes, even after balancing for many other risk factors, Ekenedilichukwu Nnadi, and lead author of the study, said in a press release. Worse insomnia, depression/anxiety or the use of other sleep-enhancing medicines might be linked to both melatonin use and heart risk. Also, while the association we found raises safety concerns about the widely used supplement, our study cannot prove a direct cause-and-effect relationship. This means more research is needed to test melatonin’s safety for the heart, Nnadi explained

Unexpected findings on melatonin and heart health are noteworthy
Melatonin is widely regarded by both the public and many in the medical community as a safe, ‘natural’ sleep aid, so it was striking to see a potential link to serious health issues like heart failure, Mody explained. While this study shows an association and not a direct cause-and-effect relationship, the consistency and significance of the increased risks are noteworthy. It’s particularly unexpected given that some previous research has suggested potential cardiovascular benefits of melatonin, such as its antioxidant properties.

This new study challenges the conventional wisdom regarding long-term melatonin use for chronic insomnia, for which it is not an indicated treatment in the United States, she continued. According to Mody, these findings suggest a re-evaluation of how we counsel patients about sleep aids and underscore the importance of discussing long-term supplement use. My concern is that insomnia may actually be masking signs and symptoms of early heart failure in some of these cases, so this research also highlights the importance of ruling out different causes of insomnia, particularly since the treatment market for insomnia aids is not strongly regulated.

Further research is needed to confirm the findings
According to Mody, the research’s next steps should concentrate on a number of crucial areas to elucidate the results and their consequences for patient care, such as causality and confirmation. She explained, “First and foremost, more research is needed to confirm these findings and to determine if there is a direct cause-and-effect relationship between long-term melatonin use and heart failure. The best way to determine whether melatonin is safe for the heart would be to conduct randomized controlled trials. Research will need to investigate the biological mechanism by which long-term melatonin use might increase the risk of heart failure if a causal link is established, Mody continued. Given that melatonin has been shown to have protective effects on the cardiovascular system, this would be a major change

How can I improve my sleep without taking melatonin?
Melatonin is available in a variety of formulations, including high and low doses, as well as slow and immediate release, none of which are FDA regulated, according to Ni’s initial response to the study. Therefore, there are worries that the levels of melatonin drugs and supplements may differ significantly. It is difficult to determine whether a particular amount or kind of melatonin is linked to an increase in heart failure.

However, considering that melatonin is not subject to FDA regulation, the study is undoubtedly concerning, he said. Ni strongly suggests that people who may be taking melatonin think about other ways to enhance the quality of their sleep. He clarified, for instance, that a lot of people have sleep apnea but are unaware of it and mistakenly believe that they just need to take a sleep aid to help them sleep. Given that sleep apnea is linked to an increased risk of heart disease, melatonin users in the study may have sleep issues.

I should also mention that melatonin and high dosages seem to have a paradoxical effect on sleep; that is, taking too much melatonin may actually make it difficult for you to fall asleep. I typically advise my patients to take no more than 1 to 3 mg of melatonin per night. Additionally, I tell my patients that because the melatonin hormone’s effect on sleepiness is gradual, it usually needs to be taken at least an hour or two before attempting to fall asleep.

High levels of heart damage biomarker may signal increased dementia risk.

High levels of heart damage biomarker may signal increased dementia risk.

Recent research suggests that higher levels of certain heart-damage biomarkers may signal an increased risk of developing dementia later in life. I’ll walk you through what has been found, what it might mean, and what we don’t yet know. A large long-term study found that people aged approximately 45-69 who had higher mid-life levels of the cardiac biomarker High‑sensitivity cardiac troponin I (hs-troponin I), which signals subtle heart muscle injury, had a significantly higher risk of being diagnosed with dementia decades later.

Specifically, those with the highest troponin levels had about a 38% higher risk of dementia compared with the lowest troponin group. The elevated troponin levels showed up 7 to 25 years before the dementia diagnosis. In a subset of participants with brain MRI, higher troponin levels were associated with smaller hippocampal volume and less grey matter brain changes consistent with aging/degeneration.

More broadly, a review article notes that several cardiac biomarkers, including troponins, N‑terminal pro­ B‑type natriuretic peptide (NT-proBNP, a marker of cardiac/ventricular stress), and Growth‑differentiation factor 15 (GDF15, a marker of vascular stress), are associated with cognitive impairment or brain changes even in people without overt heart disease. A meta-analysis of coronary heart disease (CHD) found that people with CHD have a higher odds (~1.45 times) of developing cognitive impairment or dementia compared to those without CHD.

What it might mean — possible mechanisms
Here are some ways in which subtle heart damage / cardiovascular dysfunction might contribute to brain aging and dementia risk:
Reduced cerebral perfusion / heart-brain blood flow link: If the heart muscle is damaged (even subtly), cardiac output or the efficiency of circulation might decline, which could impair blood flow to the brain over the years. The brain is highly sensitive to its blood supply.

Vascular damage and micro-injuries: Biomarkers of cardiac injury or stress also correlate with vascular stress. This may manifest in the brain as white matter changes, microinfarcts, or reduced brain tissue volume (as found in the MRI subset).

Shared risk factors: Many heart injury markers are elevated in the presence of high blood pressure, diabetes, high cholesterol, obesity, smoking, etc. These risk factors also contribute to dementia. So part of the association may be explained by overlapping risk pathways.

Early warning / silent damage: The troponin elevations in the study were associated with “subclinical” heart damage (i.e., no overt symptomatic heart disease at baseline). That suggests damage begins much earlier than clinical diagnoses and may set the stage for brain aging for decades.

What we don’t yet caution:
These findings are observational in nature. That means we can’t yet say the elevated troponin caused the dementia, only that there’s an association. Indeed, the Mendelian-randomisation study found little evidence for a causal effect of genetically elevated cardiac biomarkers on dementia risk.

Exactly what threshold of troponin (or other biomarkers) is meaningful, and at what ages, is not yet firmly established. While plausible pathways exist (blood flow, microvascular injury, overlap of cardiovascular & cerebrovascular disease), the precise chain of events linking heart damage → brain injury → dementia remains under investigation.

Many of the studies focus on specific cohorts (e.g., the Whitehall II Study in the UK) and mostly middle-aged adults initially without heart disease. Whether the same associations hold in other populations, ethnicities, or older age groups is still being defined. If elevated cardiac biomarker levels identify a higher risk of dementia, we don’t yet have solid evidence that intervening specifically based on these biomarker levels (e.g., in addition to standard cardiovascular care) will reduce dementia risk.

Implications for health & prevention:
Mid-life heart health appears increasingly important for brain health in later life. What happens to the heart, vessels, and circulation may matter for the brain decades later. Monitoring cardiovascular risk factors (blood pressure, lipids, diabetes, smoking, obesity, physical activity) remains very important because these are modifiable and already known to influence dementia risk.

The idea of using cardiac biomarkers (like troponin) as part of a dementia risk assessment is emerging but not yet ready for routine clinical use solely for that purpose. For individuals, focusing on good cardiovascular health is also brain-health care. Eat healthy, exercise, manage weight/diabetes/hypertension, avoid smoking, and keep cholesterol/lipids in check. For clinicians/researchers: These findings may guide future work on early identification of who is at risk, and possibly on targeting brain-protective interventions earlier in those with evidence of silent cardiovascular damage.

Elevated levels of cardiac injury biomarkers (especially high-sensitivity troponin) measured in mid-life are associated with an increased risk of dementia many years later, potentially reflecting that silent heart damage is setting the stage for brain aging/neurovascular injury. While this doesn’t prove causation, it strengthens the notion that the heart-brain connection is significant and that protecting cardiovascular health may help reduce dementia risk. If you like, I can pull up the full study details (sample size, follow-up years, exact biomarker levels, cognitive outcomes) and we can discuss how strong the evidence is and what it might mean for clinical practice. Would you like that?

Additionally, scientists discovered that study participants with high levels of troponin between the ages of 45 and 69 experienced a quicker decline in their memory, thinking, and problem-solving abilities. These participants also tended to have a smaller hippocampus and lower gray matterTrusted Source brain volume, both of which are signs of dementia. Poor heart health in middle age puts people at increased risk of dementia in later life,

Damage to the brain seen in people with dementia accumulates slowly over the decades before symptoms develop. Control of risk factors common to both heart disease, stroke, and dementia in middle age, such as high blood pressure, may slow or even stop the development of dementia as well as cardiovascular disease. We now need to carry out studies to investigate how well troponin levels in the blood can predict future dementia risk. Our early results suggest that troponin could become an important component of a risk score to predict the future probability of dementia.

Could Heart Attacks Be Infectious? Study Points To Hidden Bacterial Triggers

Could Heart Attacks Be Infectious? Study Points To Hidden Bacterial Triggers

Comments 0 Comment

This is a fascinating and important area of medical research that moves beyond the traditional risk factors for heart disease.

Here’s a breakdown of what that link means, the science behind it, and what it implies for the future.

The Core Finding: It’s Not Just About Cholesterol and Blood Pressure

For decades, the primary focus for heart attack (myocardial infarction) risk has been on factors like:

  • High Cholesterol
  • High Blood Pressure
  • Smoking
  • Diabetes
  • Obesity
  • Family History

The new research suggests that chronic inflammation caused by bacterial infections may be a significant, independent trigger for the events that lead to a heart attack.

How Could Bacteria Cause a Heart Attack?

The connection isn’t that bacteria directly “eat” the heart. Instead, it’s a more indirect process related to atherosclerosis (the hardening and narrowing of arteries due to plaque buildup).

  1. The Inflammatory Spark: Bacteria from chronic, often low-grade infections (like gum disease or respiratory infections) can enter the bloodstream. The body’s immune system responds by sending inflammatory cells to fight them.
  2. Plaque Vulnerability: This systemic inflammation doesn’t just target the bacteria. It can also make the fatty plaques in your arteries (atherosclerotic plaques) unstable and “vulnerable.” Inflammation weakens the fibrous cap that covers a plaque, making it more likely to rupture.
  3. The Final Clot: When a vulnerable plaque ruptures, its contents spill into the artery. The body mistakes this as an injury and forms a blood clot (thrombus) to seal it. If this clot is large enough, it can completely block the coronary artery, cutting off blood flow to the heart muscle and causing a heart attack.

Key Bacterial Suspects

Research has pointed to several specific bacteria as potential culprits:

  • Porphyromonas gingivalis: This is a primary bacterium associated with periodontitis (severe gum disease). There is a very strong and well-documented link between gum health and heart health. The theory is that bleeding gums provide an easy entry point for these bacteria into the bloodstream.
  • Streptococcus pneumoniae: The common bacteria that causes pneumonia, sinusitis, and other respiratory infections. Studies have shown it can invade heart tissue and directly promote clot formation.
  • Chlamydia pneumoniae: This respiratory pathogen has been found embedded within atherosclerotic plaques themselves, suggesting it may play a direct role in plaque development and instability.
  • Helicobacter pylori: Known for causing stomach ulcers, this bacteria is also linked to systemic inflammation that could contribute to cardiovascular risk.

What Does This Mean for You? Key Takeaways

  1. Oral Hygiene is Heart Hygiene: This is the biggest practical takeaway. The link between gum disease and heart disease is powerful. Brushing, flossing, and regular dental check-ups are not just about saving your teeth—they could be vital for protecting your heart.
  2. Don’t Ignore Chronic Infections: Persistent low-grade infections (like gum disease, respiratory issues, or others) should be taken seriously and treated promptly, as they may be contributing to systemic inflammation.
  3. It’s a “Trigger,” Not a Solo Cause: It’s crucial to understand that bacterial infection is likely a trigger that acts on top of existing risk factors. Someone with clean arteries is unlikely to have a heart attack from a bacterial infection alone. But for someone with significant plaque buildup, a bacterial infection could be the final straw.
  4. Antibiotics Aren’t the Answer (Yet): Large clinical trials using broad-spectrum antibiotics to prevent heart attacks have largely failed. This suggests the relationship is more complex than a simple infection that can be “cured” with a short course of antibiotics. It may be related to the body’s inflammatory response rather than the bacteria themselves.

The Future of Treatment and Prevention

This research opens up new avenues for medicine:

  • Vaccines: Developing vaccines against specific bacteria like S. pneumoniae could have the dual benefit of preventing infections and reducing heart attack risk.
  • Anti-inflammatory Therapies: It strengthens the rationale for using targeted anti-inflammatory drugs for heart disease prevention.
  • Novel Diagnostics: In the future, testing for certain bacterial markers or specific inflammatory signals might help identify individuals at very high risk for a heart attack.

In conclusion, the study is correct. While traditional risk factors remain critically important, the role of chronic bacterial infections and the inflammation they cause is a significant and evolving piece of the heart disease puzzle. Maintaining good overall health, with a special emphasis on oral hygiene, is a powerful step you can take to mitigate this newly understood risk.

Importance of Potassium in Cardiovascular Disease

Importance of Potassium in Cardiovascular Disease

Comments 0 Comment

The potential for potassium supplements to lower heart failure risk is primarily linked to its critical role in regulating blood pressure and maintaining normal electrical function in the heart. However, it’s crucial to understand that this relationship is a “Goldilocks” scenario—not too little, not too much, but just the right amount.

Here’s a breakdown of the mechanisms by which adequate potassium intake might help lower the risk of heart failure:

1. Lowering Blood Pressure (The Most Significant Factor)

High blood pressure (hypertension) is the number one risk factor for developing heart failure. It forces the heart to work much harder to pump blood, which, over time, causes the heart muscle to thicken and stiffen (a condition called left ventricular hypertrophy) and eventually weakens it.

  • How Potassium Works: Potassium helps lower blood pressure through two main actions:
    • Counteracting Sodium: Potassium promotes the excretion of sodium through the urine. Sodium holds onto water in the body, increasing blood volume and, consequently, blood pressure. By helping the body get rid of sodium, potassium reduces blood volume and eases the pressure on blood vessel walls.
    • Vasodilation: Potassium helps the walls of the blood vessels relax and widen (dilate). This reduces resistance to blood flow, making it easier for the heart to pump and lowering blood pressure.

By effectively managing blood pressure, adequate potassium intake directly addresses the primary driver of heart failure risk.

2. Preventing Cardiac Arrhythmias (Abnormal Heart Rhythms)

The heart’s rhythm is controlled by a delicate and continuous electrical impulse. Potassium is one of the key electrolytes (along with sodium, calcium, and magnesium) that governs this electrical activity.

  • Stable Electrical Activity: Potassium is essential for “repolarizing” the heart muscle cells after they contract, resetting them for the next beat. This ensures a stable, regular heartbeat.
  • The Danger of Imbalance:
    • Low Potassium (Hypokalemia): Can cause the heart to beat abnormally, leading to arrhythmias like atrial fibrillation or even more dangerous ventricular arrhythmias. These irregular rhythms can reduce the heart’s pumping efficiency and are a known cause and consequence of heart failure.
    • High Potassium (Hyperkalemia): Can be equally dangerous, slowing the heart rate to a point where it can become life-threatening.

Maintaining a normal potassium level is therefore critical for preventing arrhythmias that can both trigger and worsen heart failure.

3. Reducing Vascular Stiffness and Protecting Blood Vessels

Over time, high blood pressure and other factors can cause blood vessels to become stiff and less elastic. This stiffness forces the heart to pump against greater resistance.

  • Potassium’s Role: Studies suggest that adequate potassium helps protect the endothelial lining of blood vessels (the inner layer) and reduces vascular stiffness. More flexible arteries mean less workload for the heart.

4. Counteracting Negative Effects of a High-Sodium Diet

The modern Western diet is notoriously high in sodium and often low in potassium. This imbalance disrupts the natural sodium-potassium pump in our cells, which is crucial for nerve function, muscle contraction, and fluid balance. By increasing potassium intake, we help restore this balance and mitigate the damaging effects of excess sodium on the cardiovascular system.

Crucial Caveats and Warnings

While the science supporting adequate dietary potassium is strong, the idea of taking potassium supplements requires extreme caution.

  1. “Food First” is the Rule: The benefits are most clearly seen from getting potassium from a diet rich in fruits, vegetables, beans, and nuts. Excellent sources include:
    • Leafy greens (spinach, kale)
    • Potatoes and sweet potatoes
    • Bananas, oranges, and avocados
    • Tomatoes and tomato products
    • Beans and lentils
    • Coconut water
  2. Supplements Can Be Dangerous: Over-the-counter potassium supplements are typically limited to 99 mg per dose (a fraction of the recommended 3,400-4,700 mg daily intake for adults) for a reason.
    • Kidney Function is Key: Healthy kidneys are excellent at removing excess potassium from the blood. However, in people with kidney disease or those taking certain medications (like some drugs for heart failure and high blood pressure, including ACE inhibitors, ARBs, and some diuretics), potassium can build up to dangerously high levels (hyperkalemia), which can cause fatal cardiac arrest.
    • Never Self-Prescribe: You should never take potassium supplements without a doctor’s supervision and a confirmed deficiency. A doctor will prescribe a supplement (often a higher-dose prescription form) only if blood tests show it’s necessary and will monitor your blood levels regularly.

Summary

Potassium might help lower heart failure risk primarily by:

  • Lowering blood pressure (the biggest factor).
  • Stabilizing the heart’s electrical rhythm to prevent arrhythmias.
  • Protecting blood vessels from stiffness.

The take-home message is not to run out and buy supplements, but to focus on eating a diet rich in potassium-filled whole foods. If you are concerned about your heart failure risk or your potassium levels, the safest and most effective step is to consult your doctor for personalized advice.

Beta Blockers, the Standard Treatment After a Heart Attack, May Offer No Benefit for Heart Attack Patients and Women Can Have Worse Outcomes

Beta Blockers, the Standard Treatment After a Heart Attack, May Offer No Benefit for Heart Attack Patients and Women Can Have Worse Outcomes

Comments 0 Comment

You’ve hit on a very important and nuanced point in cardiology. The statement “Beta-blockers may be harmful for women with some heart conditions” is an oversimplification of a complex issue, but it points to a real and critical area of research: sex-based differences in cardiovascular disease and treatment.

Let’s break down what this means, separating fact from fiction.

The Core of the Issue: Not “Harmful” but “Potentially Less Effective or Different Risk-Benefit”

For the vast majority of heart conditions (like coronary artery disease, heart attack, heart failure), beta-blockers are lifesaving for both men and women. The benefits are well-proven.

However, research over the past two decades has revealed that the degree of benefit and the side effect profile can differ significantly between women and men. The idea of “harm” primarily comes from two areas:

  1. Increased Side Effects: Women consistently report a higher incidence and severity of side effects from beta-blockers.
  2. Lack of Efficacy in Certain Female-Predominant Conditions: For some conditions that primarily affect women, beta-blockers may not work as intended and could potentially exacerbate symptoms.

1. Increased Side Effects in Women

Women are more likely to experience side effects from beta-blockers, often at the same doses prescribed to men. This is due to well-documented pharmacokinetic and pharmacodynamic differences:

  • Body Size and Composition: Women generally have lower body weight, less muscle mass, and a higher percentage of body fat, which can affect drug distribution.
  • Metabolism: Enzymes in the liver (like CYP450) that metabolize drugs can work differently in women.
  • Absorption and Elimination: Gastrointestinal motility and kidney function can vary.

Common side effects that are more frequent or severe in women include:

  • Bradycardia (excessively slow heart rate)
  • Hypotension (low blood pressure)
  • Fatigue and Depression
  • Cold hands and feet (due to peripheral vasoconstriction)

The “Harm” Here: If side effects are severe enough, they can lead to poor quality of life and, crucially, non-adherence to medication. A patient who stops taking a lifesaving drug because of intolerable side effects is certainly being harmed by the therapy in an indirect way.

2. Specific Heart Conditions Where Beta-Blockers Are Questioned for Women

This is where the “harm” concept becomes more direct.

A. Coronary Microvascular Dysfunction (CMD)

  • What it is: A condition where the tiny blood vessels (microvasculature) in the heart don’t function properly, causing chest pain (angina). It is much more common in women, especially after menopause.
  • The Problem with Beta-Blockers: Traditional beta-blockers work mainly on larger coronary arteries. In CMD, the problem is in the microvessels. Some beta-blockers that are non-selective (like propranolol) can cause unopposed alpha-receptor stimulation, leading to constriction of these very microvessels, potentially worsening blood flow and chest pain.
  • Current Thinking: Cardiologists are now more cautious. While certain beta-blockers can still be helpful for controlling heart rate, they are not a one-size-fits-all solution for CMD. Other medications like calcium channel blockers (e.g., verapamil) or ranolazine are often preferred or used in combination.

B. Takotsubo Cardiomyopathy (“Broken Heart Syndrome”)

  • What it is: A temporary weakening of the heart muscle, often triggered by extreme stress. It overwhelmingly affects postmenopausal women.
  • The Problem with Beta-Blockers: The long-term use of beta-blockers for Takotsubo patients is controversial. Since the condition is often triggered by a massive catecholamine (adrenaline) surge, the intuitive thought was to block these receptors. However, large registry studies have not shown a clear benefit for beta-blockers in preventing recurrence. There is a theoretical concern that in the acute phase, certain beta-blockers could worsen the condition by leading to unopposed alpha-effects and increased blood pressure.

C. Heart Failure with Preserved Ejection Fraction (HFpEF)

  • What it is: A type of heart failure where the heart pumps normally but is too stiff to fill properly with blood. It is more common in older women, especially those with hypertension, obesity, and diabetes.
  • The Problem with Beta-Blockers: Unlike Heart Failure with Reduced Ejection Fraction (HFrEF), where beta-blockers are a cornerstone of therapy, no medication has conclusively been proven to reduce mortality in HFpEF. Beta-blockers are often prescribed to control heart rate or atrial fibrillation, but they can sometimes worsen the problem by limiting the heart rate needed to fill a stiff ventricle, leading to low cardiac output and fatigue.

The Bigger Picture: The Historical Lack of Women in Clinical Trials

A major reason these differences are only now being understood is that for decades, cardiovascular clinical trials predominantly enrolled middle-aged men. The results were then applied to women, assuming the biology and response were the same. We now know this is not the case.

Conclusion and Key Takeaway

It is inaccurate and dangerous to say that women with heart conditions should avoid beta-blockers. For conditions like heart attack and heart failure with reduced ejection fraction, they are essential.

However, the correct, modern interpretation is:

Cardiovascular treatment must be personalized, and biological sex is a critical factor in that personalization. For women, especially with conditions like coronary microvascular dysfunction, Takotsubo cardiomyopathy, or HFpEF, the use of beta-blockers requires careful consideration. The choice of specific beta-blocker, the dose, and the balance of benefits versus a higher risk of side effects must be thoughtfully evaluated by a healthcare provider.

If you are a woman prescribed a beta-blocker, the most important thing is to:

  • Take it as prescribed unless your doctor tells you otherwise.
  • Report any side effects to your doctor promptly. Do not just stop taking the medication.
  • Have an open conversation with your cardiologist about the specific reason for the prescription and whether it’s the best option for your particular heart condition.

Plant compound in nuts, veggies, and fruit may lower diabetes, heart disease risk

Plant compound in nuts, veggies, and fruit may lower diabetes, heart disease risk

Comments 0 Comment

A plant compound found in nuts, vegetables, and fruits that may lower the risk of diabetes and heart disease is polyphenols. Among these, flavonoids (a subclass of polyphenols) are particularly well-studied for their health benefits.

Key Polyphenols and Their Sources:

  1. Flavonoids
    • Found in: Berries, apples, citrus fruits, tea, dark chocolate, onions, and red wine.
    • Benefits: Improve insulin sensitivity, reduce inflammation, and support cardiovascular health.
  2. Resveratrol
    • Found in: Grapes, red wine, peanuts, and berries.
    • Benefits: May improve blood sugar control and reduce heart disease risk by improving endothelial function.
  3. Lignans
    • Found in: Flaxseeds, sesame seeds, whole grains, and nuts.
    • Benefits: Linked to better glycemic control and reduced LDL cholesterol.
  4. Ellagic Acid
    • Found in: Pomegranates, strawberries, walnuts, and raspberries.
    • Benefits: Antioxidant and anti-inflammatory effects that may protect against metabolic syndrome.

How They Help:

  • Improve Insulin Sensitivity: Polyphenols can enhance glucose metabolism by activating AMPK (an enzyme that regulates energy balance).
  • Reduce Inflammation: They lower oxidative stress and inflammatory markers like CRP and TNF-α.
  • Support Heart Health: Improve endothelial function, reduce blood pressure, and lower LDL cholesterol.

Evidence:

  • A 2020 study in Nutrients found that high polyphenol intake was associated with a 30% lower risk of type 2 diabetes.
  • Research in The American Journal of Clinical Nutrition showed that flavonoids reduced heart disease risk by 20% in high consumers.

Practical Tips:

  • Eat a variety of colorful fruits and vegetables daily.
  • Include nuts (like almonds and walnuts) and seeds (flaxseeds, chia) in your diet.
  • Opt for dark chocolate (70%+ cocoa) and green tea for extra polyphenols.
