Does Coffee Cause Atrial Fibrillation

Measurement Of Caffeine Consumption

Can Food or Drinks Cause Arrhythmias Like Atrial Fibrillation?

All cohort members completed a detailed, semiquantitative food-frequency questionnaire . Descriptions of the development and validation of this questionnaire were published previously . The daily intake of specific foods and nutrients was calculated from the FFQ for each participant with the use of FOODCALC software . Standard recipes and sex-specific portion sizes were applied to calculate intake in grams per day by using data from different sourcesie, the 1995 Danish National Dietary Survey , 24-h diet recall interviews from 3818 of the study participants , and various cook books. We summed the daily intake of caffeine from coffee, tea, cola, cocoa, and chocolate for each subject.

Although the research doesnt currently support a link between caffeine and arrhythmias, if you find caffeine seems to worsen the condition, consider cutting down.

There are patients who may be sensitive to caffeine and note the onset of palpitations or worsening palpitations with low or any caffeine intake, Van Herle says. I usually advise my patients with palpitations that are worsened with caffeine to cut down if they can and reassure others with arrhythmias, that are not affected by caffeine, that they can continue to use it in moderate amounts.

But there might be one exception to the caffeine rule for heart health. In general I do advise my patients to stay away from high energy drinks that contain very high caffeine content, Van Herle adds.

Irregular heartbeat, which can feel like a fluttering or racing heart, is a cause for concern because it may mean your heart isnt working properly. It can be a sign of heart disease, including coronary artery disease or cardiomyopathy . But, according to the American Heart Association, most arrhythmias are actually harmless. Only a doctor can tell for sure, so report an arrhythmia to your health care professional if you experience it.

Should You Avoid Caffeine If You Have Heart Palpitations

Try drinking less tea and coffee as well as eliminating coffee and soda from your schedule. The cardiovascular palpitations linked to eating large quantities of chocolate have been found to occur when chocolate is consumed repeatedly. In addition to giving caffeines effects, chocolate can trigger an abnormal heart rate if eaten in large quantities.

Frequent Coffee Consumption Is Associated With Lower Incidence Of Arrhythmias A New Study Reveals That Drinking A Couple Of Daily Cups Of Coffee Does Not Lead To A Greater Risk Of Arrhythmias Potentially Debunking A Common Myth That Consuming Caffeine In Coffee And Other Drinks Could Lead To A Faster Heartbeat And The Potential For A Triggered Arrhythmia For This Patient Population 2020 Press Release

New Study Aims to Address The Myths And Anxiety Around Caffeine Consumption Among Heart Rhythm Patients

WASHINGTON, D.C., May 5, 2020 A new study reveals that drinking a couple of daily cups of coffee does not lead to a greater risk of arrhythmias, potentially debunking a common myth that consuming caffeine in coffee and other drinks could lead to a faster heartbeat and the potential for a triggered arrhythmia for this patient population. Researchers analyzed several types of arrhythmias to better understand the impact of caffeine on this common heart condition. Results from this observational study were released today as part of Heart Rhythm Society 2020 Science.

Americans are dependent on their daily dose of caffeine, with more than 64 percent of Americans drinking a cup of coffee every day1. Patients with arrhythmias are often cautioned against regular consumption by their doctors. Despite this specific concern, caffeine also offers health benefits, including antioxidants, improved metabolism, enhanced exercise performance, and increased alertness and concentration2. Studies have also shown regular coffee consumption can also yield positive heart health results, lowering the risk of heart disease and stroke3. With evidence showing caffeine’s positive impact on general heart health, there is a need to better understand the relationship between regular coffee consumption and arrhythmias.


Are Alcohol And Caffeine Triggers That Can Cause A

Coffee and Atrial Fibrillation: True or False?

Many health experts believe there is a connection between caffeine, alcohol, and A-fib, and that either substance can trigger an attack. However, researchers are still investigating the specific causes.

Many factors identified as possible triggers for A-fib may work alone or together to cause the condition. This makes it difficult to establish what is or is not a trigger.

As a result, it is also hard to work out how much coffee or alcohol could trigger an episode of A-fib.

Alcohol is a known trigger for a specific form of A-fib known as holiday heart syndrome . HHS is the sudden appearance of A-fib in individuals who are otherwise healthy, but who recently took part in binge drinking. The Centers for Disease Control and Prevention define binge drinking as more than five drinks for men and four drinks for women in a 2-hour period.

Researchers have noticed these cases are more frequent after weekends and holidays linked with increased alcohol use, which is how HHS got its name.

In addition, some studies have found a connection between the risk of A-fib and chronic, alcohol use. A connection was not found for moderate drinkers.

A 2005 study exploring caffeine use in Scandinavia did not find any connection between A-fib and caffeine use.

The scientific community is divided on whether or not people with A-fib can consume alcohol or caffeine safely.

The American Heart Association advise individuals with A-fib to avoid excessive amounts of alcohol and caffeine.

Dunk Your Head In Cold Water

As the old saying goes, âMay cooler heads prevail,â and that holds especially true if you have an episode of AFib with a rapid heart rate. When you dip your head in cold water or take a cold shower, you stimulate the vagal nerve, which slows your heart rate. Even holding an ice cube to your forehead or standing at an open freezer door for a few minutes may do the trick.

Try The Valsalva Maneuver

A breathing technique called the Valsalva maneuver can prevent an AFib episode. You donât need any special equipment, and you can do it pretty much anywhere. Simply pinch your nostrils and keep your mouth closed while attempting to breathe for 10 to 15 seconds. This increases the pressure inside your ear and chest, which reduces some heart arrhythmias. Your ears might pop, and thatâs OK. Just donât blow too hard, as it might damage your ear.

Afib And Caffeine The Research

Atrial fibrillation is the most widespread cardiac arrhythmia, affecting 25% of people during their lifetime.

AFib happens when the two upper chambers of the heart, called the atria, lose their ability to send electrical impulses to both lower chambers, called the ventricles. The disruption in this essential conduction process causes an erratic heart rate, often accompanied by chest discomfort, shortness of breath and fatigue.

The standard of care for many years has been to counsel people with AFib to stop caffeine consumption immediately.

However, more than 20 clinical studies about the effects of caffeine on AFib since 2000 lack conclusive evidence demonstrating that caffeine has a detrimental effect on AFib.

The Research About Caffeine Intake and AFib

Is Caffeine Safe Protective For Patients With Afib Arrhythmias

What is atrial fibrillation?

Some caffeinated beverages such as coffee and tea may be safe and may reduce the frequency of arrhythmias, according to a state-of-the-art-review published April 16 in JACC: Clinical Electrophysiology.

Aleksandr Voskoboinik, MBBS, et al., analyzed multiple population-based studies to determine an association between caffeine intake and its effects on atrial and ventricular arrhythmias. The studies consistently showed a decrease in atrial fibrillation with an increase in caffeine ingestion, with one meta-analysis of 228,465 participants showing AFib frequency decreasing by 6 percent in regular coffee drinkers, and a further analysis of 115,993 patients showing a 13 percent risk reduction.

The authors found that caffeine does not appear to increase the likelihood of ventricular arrhythmia. In addition, caffeine doses up to 500 mg daily did not increase the severity or rate of ventricular arrhythmias. A randomized study of 103 post-MI patients who received an average of 353 mg/day resulted in improved heart rate and no significant arrhythmias. Only two studies showed an increased risk for ventricular arrhythmias, in which patients ingested at least 10 cups and nine cups per day, respectively. According to the authors, energy drinks should be avoided by patients with pre-existing heart conditions. Three quarters of patients with pre-existing heart conditions who consumed two or more energy drinks per day reported palpitations within 24 hours.

Other Risk Factors For A

Interestingly, people with A-fib report that the same activities, such as going for a walk, might prompt an attack one day and not the next.

Additionally, heart disease is a known risk factor for A-fib, as are age, obesity, and genetics, hyperthyroidism, diabetes, chronic kidney disease, and European ancestry.

However, there is a closer connection between obstructive sleep apnea and A-fib than any other risk factor.

A list of further potential A-fib causes includes:

  • certain medical procedures
  • exercise

What Are Heart Palpitations

Most of the time, youre likely unaware of the beating or rhythm of your heart. A normal resting heart rate is 60 to 100 beats-per-minute, and the heart has a characteristic rhythm when it beats. Unless your heart is beating fast or hard, you likely wont notice it beating.

Heart palpitations are the feeling that your heart is beating irregularly. It may feel like its pounding, beating too fast, or fluttering. Common causes of heart palpitations include:

  • Stress
  • Exercise
  • Certain medications

Stimulants, including caffeine, are known to affect heart rate, but just how does caffeine affect the heart?

Heart Beat: Atrial Fibrillation Don’t Blame Caffeine

Caffeine has long been suspected to be a trigger for atrial fibrillation, an all-too-common problem that turns the steady, coordinated beat of the heart’s upper chambers into a fast, erratic churn. While it is possible that drinking eight cups of espresso in an afternoon could spark atrial fibrillation, moderate caffeine consumption has little effect on its development, according to a large Harvard-based study.

Researchers followed more than 33,000 participants of the Women’s Health Study for 14 years. Over the course of the study, atrial fibrillation developed in just as many women in the group with the lowest caffeine intake, about one cup of coffee a week, as it did in the group with the highest caffeine intake, about six cups a day . The source of caffeine coffee, tea, cola, or chocolate didn’t make a difference.

Avoid Alcohol Especially Binge Drinking

Coffee and Atrial Fibrillation: True or False?

If you really tie one on, or binge drink, you may feel an AFib episode, or the so-called holiday heart syndrome, the next day. But even just having a beer or two daily can bring on a rapid heartbeat and other AFib symptoms. To reduce your odds of having an AFib attack, swap out alcoholic beverages for water or another low-calorie drink.

Can Caffeine Be A Cause

Some people with atrial fibrillation are convinced that caffeine makes their symptoms worse. On the other hand, research doesnât support this. According to a study published in the American Journal of Clinical Nutrition and published on Medscape.com, caffeine doesnât cause atrial fibrillation.

In this large study involving almost 48,000 middle-aged and older people, researchers compared the risk of atrial fibrillation to how much caffeine the participants took in daily. After following them for 5.5 years to see how many developed atrial fibrillation, they found no association between caffeine consumption and atrial fibrillation risk.

One flaw in the study was they didnât have a group who consumed no caffeine. Itâs possible that completely abstaining from caffeine could lower the risk of atrial fibrillation, but this would need to be researched. This study also only looked at consumption of caffeine from coffee – not tea, soft drinks or chocolate. It would be even more convincing to see no increase in atrial fibrillation risk from caffeine in any form. They did find that caffeine in coffee slightly increases blood pressure when five or more cups are consumed a day.

Guidelines For Afib And Caffeine Intake

If you are someone who enjoys foods and beverages containing caffeine on a regular basis, continuing consumption will not likely trigger an episode of AFib if you monitor your intake and make wise choices .

  • Cut out or abstain from caffeine if you have a history of sensitivity to it.
  • Keep your consumption to a moderate and consistent amount, as increasing your intake could lead to an AFib episode.
  • Make sure to always read labels on any over-the-counter cold medications or pain relievers if you have a history of adverse reactions to.

    Caffeine Consumption From Coffee And Atrial Fibrillation

    Atrial fibrillation is the most common cardiac arrhythmia and involves the two upper chambers of the heart. People with atrial fibrillation usually have a significantly increased risk of stroke.

    To date, research has not demonstrated an association between coffee consumption and risk of atrial fibrillation, although some studies have suggested that coffee consumption may have a protective effect25-32:

    Coffee Doesnt Raise Your Risk For Heart Rhythm Problems

    UCSF Cardiology Researchers Report No Link Between Coffee Consumption and Arrhythmia

    In the largest study of its kind, an investigation by UC San Francisco has found no evidence that moderate coffee consumption can cause cardiac arrhythmia.

    In fact, each additional daily cup of coffee consumed among several hundred thousand individuals was associated with a 3 percent lower risk of any arrhythmia occurring, including atrial fibrillation, premature ventricular contractions, or other common heart conditions, the researchers report. The study included a four-year follow up.

    The paper is published July 19, 2021, in JAMA Internal Medicine.

    Coffee is the primary source of caffeine for most people, and it has a reputation for causing or exacerbating arrhythmias, said senior and corresponding author Gregory Marcus, MD, professor of medicine in the Division of Cardiology at UCSF.

    But we found no evidence that caffeine consumption leads to a greater risk of arrhythmias, said Marcus, who specializes in the treatment of arrhythmias. Our population-based study provides reassurance that common prohibitions against caffeine to reduce arrhythmia risk are likely unwarranted.

    In the new study, UCSF scientists explored whether habitual coffee intake was associated with a risk of arrhythmia, and whether genetic variants that affect caffeine metabolism could modify that association.

    Disclosures can be found in the paper.

    Coffee Caffeine And Atrial Fibrillation

    Caffeine is the most widely consumed behaviorally active substance in the world and almost all caffeine comes from dietary sources, most of it from coffee Associations between coffee, caffeine and AF have had conflicting results. Coffee contains several hundred different substances including lipids, carbohydrates, minerals, vitamins, alkaloids and phenolic compounds. Nevertheless effects of coffee on cardiovascular system have been mainly related to caffeine.

    Caffeine is an alkaloid present in coffee beans, in humans come from a number of dietary sources i.e. tea, coffee, cocoa beverages, chocolate bars and soft drinks and recently energy drinks. . The content of caffeine of these items ranges from 4 to 180 mg/150 ml for coffee, 15 to 29 mg/180 ml for cola, 24 to 50 mg/150 ml for tea, 2 to 7 mg/150 ml for cocoa and 1 to 36 mg/28 mg for chocolate, 100 to 286 mg for common ED, however some brands of ED contain 550 mg caffeine per can or bottle.

    The clinical effect of intakes of caffeine from coffee, tea, caffeinated soda and energy drinks on AF remain inconclusive. The patho-physiology of the arrhythmias have been described in detail, however the mechanism underlying electrical changes and the possible triggering factors remain largely unknown. Several studies evaluated the acute effects of caffeine on heart rate and found controversial results.

    Caffeine toxicity produces supraventricular tachycardia, atrial fibrillation and ventricular fibrillation.

    Coffee and Atrial Fibrillation: What

    In general, researchers found no evidence that caffeine intake leads to abnormal heart rhythms as a result of abnormal heart rhythms. The majority of studies conducted on this topic reveal the opposite: that coffee and tea consumption actually reduces the risk for cardiovascular rhythms like atrial fibrillation in most cases.
