I’ve posted a new Frequently Asked Question and Answer about A-Fib that runs in families:
“Both my uncles and my Dad have Atrial Fibrillation. I’m 50 years old and so far I don’t have A-Fib (yet), but I’m worried. How can I avoid developing A-Fib? Can dietary changes help? Or lifestyle changes?”
A-Fib does run in families and is called Familial A-Fib. Research says you have a 40% increased risk of developing A-Fib yourself. And the younger your uncles and dad were when they got A-Fib, the more likely you are to develop A-Fib. So, you are correct to be concerned about getting A-Fib.
My answer covers:
• What can someone with A-Fib in the family do to avoid getting A-Fib?
• Is there a diet to prevent A-Fib? The Mediterranean diet? A whole-food organic diet?
• What are the causes of A-Fib that can be controlled?
• Do mineral deficiencies cause A-FIb?
• What are the vitamins and supplements known to improve your overall heart health? (I take these myself to help stay A-Fib free after my 1998 catheter ablation which isolated only one of my pulmonary vein, common at the time.)
Read my full answer at FAQs: Can I Prevent Familial A-Fib with Diet? Supplements?

Note: Most heart health eating plans aim to improve the ‘plumbing’ of the heart, whereas A-Fib is primarily an ‘electrical’ problem.
A Heart Healthy Diet and Lifestyle
While there’s no “Atrial Fibrillation diet” proven to prevent, stop or cure A-Fib, anything that improves your overall heart health might indirectly affect developing A-Fib.
Start with a ‘heart healthy’ diet and healthy lifestyle. There are lots of on-line resources and books about eating healthy for your heart.
• The U.S. National Heart, Lung and Blood Institute recommends the “DASH” eating plan which reduces the risk of developing cardiovascular disease;
• A Mediterranean diet may reduce the risk of atrial fibrillation, according to a article by Case Adams, a board-certified Naturopath;
• A whole-food organic diet is “preferred” for A-Fib patients, states Naturopathic doctor (ND) Dan Carter. But he doesn’t claim that this diet will prevent or cure A-Fib.
A-Fib Causes: Some are Under Your Control
The four main causes or co-morbidities of A-Fib are sleep apnea, obesity, hypertension and diabetes. If you have any of these conditions, it’s important to get them under control.
Binge drinking has been known to start one’s A-Fib, as well as smoking and excessive stress or anxiety. Avoid these as much as you can. (Also, many patients develop A-Fib post-surgery due to sudden low levels of magnesium.)
Dehydration can contribute to A-Fib. Too much alcohol or caffeine and too little water can alter the fluid levels in your body. Consume an adequate amount of water especially on hot days and when exercising.
Vitamins, Supplements and Herbs
Several vitamins, supplements and herbs have been shown to reduce or eliminate A-Fib symptoms. Magnesium and Potassium deficiencies are prevalent among A-Fib patients, as well as Calcium overload. Read more on our Mineral Deficiencies page.
For a list of 7 other vitamins and supplements known to improve your overall heart health, see my article: ‘Natural’ Supplements for a Healthy Heart’. (I take these myself to help stay A-Fib free after my 1998 catheter ablation which isolated only one of my pulmonary vein, a common treatment strategy at the time.)
What This Means to Families of A-Fib Patients
With A-Fib running in your family, you have a 40% increased risk of developing A-Fib yourself. And the younger your uncles and dad were when they got A-Fib, the more likely you are to develop A-Fib.
The younger your uncles and dad were when they got A-Fib, the more likely you are to develop A-Fib.
While there’s no diet to prevent A-Fib, you can get control of co-morbidities such as obesity, sleep apnea, diabetes and high blood pressure. And you can avoid lifestyle choices like binge drinking, smoking, excessive stress and anxiety that increase your odds of A-Fib. (If you have surgery, ask your doctor about Magnesium IV post-op).
Above all, choose a healthy heart lifestyle, exercise, don’t overindulge and eat well.

The Facts About Women with A-Fib: Mother Nature and Gender Bias—Or—Get Thee to an EP ASAP
by Patti J. Ryan, August 2015
Several studies have established that the symptoms and consequences of A-Fib are more profoundly felt in women.
Mother Nature and A-Fib Symptoms in Women
Females tend to develop A-Fib at a later age than men. They are also more likely to seek medical attention, are usually more symptomatic, and have higher heart rates. A-Fib tends to affect their physical quality of life more severely.
While men as a group develop A-Fib twice as often as women, there are twice as many females as males in the age group with the highest percentage of A-Fib.
Cardiovascular mortality rates are 2.5-fold greater for women with A-Fib. Women have a 4.6-fold higher rate of stroke. A-Fib is the most frequent cause of disabling stroke in elderly females.
Remember: you don’t have to live with A-Fib! Seek your cure.
What can you do about it? As a female with A-Fib, you may have more symptoms, quality of life issues and are at greater risk of an A-Fib-related stroke. But you don’t have to live with A-Fib. As soon as practical, get a referral to a heart rhythm specialist (a cardiologist with a specialty in electrophysiology). Early diagnosis means less damage to your heart and more treatment options.
Drug Therapies for Women with A-Fib and Risk of Stroke
Women fail more antiarrhythmic drugs therapies than men. Women don’t do well on some antiarrhythmic drugs (estrogen may prolong the QT interval).
Antiarrhythmic drug therapy in women with hypertension is associated with more major cardiovascular events. (Some research indicates that women may have more hypertension than men, 55.2% vs 40%).
What this means to patients: “Drugs don’t cure A-Fib but merely keep it at bay,” says heart rhythm specialist, Dr. Dhiraj Gupta. Antiarrhythmic drugs only work for about 50% of patients, and often stop working after a period of time. Many can’t tolerate the side effects.
Don’t spend a year in A-Fib trying different medications or combinations of medications only to find none work for you. In addition, anticoagulants, like warfarin, for your increased stroke risk, have their own health risks. Don’t live a life on medication. Seek your cure.
Differences in Catheter Ablation for Females with A-Fib
Women, in general, have smaller cardiac chambers so that catheter manipulation is more of a challenge (40.6 mm on average for women vs 44.6 mm for men). (However, since research data shows there is a significant delay in referral for ablation in women, it is feasible that they may have larger left atrial sizes due to remodeling, making this a moot point.)
Run, don’t walk to the best heart rhythm specialist (an electrophysiologist) you can find.
Females have more non-PV triggers and have lower ablation success rates.
Females tend to have more ablation complications like pericardial tamponade and vascular complications.
What can you do about it? Don’t delay. “Run, don’t walk” to the best heart rhythm specialist (an electrophysiologist) you can find, advises former A-Fib patient Sheri Weber. A-Fib is a progressive disease. Consult an EP after your diagnosis. Don’t wait for your A-Fib to get worse. (A-Fib rarely gets better.)
Gender Bias Also Plays a Role
Women are referred to A-Fib specialists three times less often than men. Men with A-Fib are managed more aggressively (such as more cardioversions) prior to seeking a catheter ablation.
Women often have developed a larger left atrium because of being referred to EPs later in their treatment plan than men (60 months for females vs 47 months for males).
Women are referred to A-Fib specialists three times less often than men.
Women are referred for catheter ablation less frequently and later into their treatment plan than men. When referred, they are older on average than men (61.6 years old vs 56.9 years old for men).
Consequently, they have more complex symptoms, and their procedure success rate is lower with more complications.
What can you do about it? When you go to your GP or cardiologist with your A-Fib symptoms or complaints, anticipate gender bias! Don’t let it deter you. A-Fib is a progressive disease. Don’t waste time. Don’t let your A-Fib worsen over time by remodeling or enlarging your heart. Request a referral to a heart rhythm specialist―an electrophysiologist (EP). Until you consult an EP, you may not be getting the best and most up-to-date A-Fib treatment advice. You deserve nothing less.
Don’t just take your meds and get used to being in A-Fib.
Why is there Gender Bias in the Treatment of Women with A-Fib?
In many cultures and societies, doctors are more conservative in their treatment of women with A-Fib. Some doctors, concerned with safety, may be reluctant to perform or recommend any invasive procedures in women.
Social and family pressures may delay medical consultation and treatment (“I can’t be sick. My family needs me.”) Access to health care may be limited for some women.
And, of course, there’s plain ol’ bias by male doctors against female patients. “Your symptoms are all in your mind.” or “Just take your meds and get used to being in A-Fib.” (These are actual quotes from A-Fib.com readers about their doctors’ advice.)
What can you do about it? Be prepared for your doctor appointment with a list of questions or concerns. Don’t leave until you have answers. Don’t be afraid to ‘fire’ your doctor. Get a second, or third opinion. Find a doctor who will partner with you to find your cure or best outcome. (For help, use the Finding the Right Doctor for You resources on A-Fib.com.)
Good News: EPs Less Likely to Have Gender Bias
Research indicates female gender bias tends to disappear when a woman sees an electrophysiologist (EP), particularly concerning catheter ablation. This suggests that treatment bias may be more at the primary care level, i.e., your GP or general cardiologist.
What this means to patients: It’s reassuring to be in the care of someone who regularly treats A-Fib patients. A-Fib is an electrical problem. Don’t waste you time. Don’t settle for just ‘managing’ your A-Fib. See a heart rhythm specialist, an electrophysiologist, a cardiologist who specializes in the electrical function of your heart. An EP will discuss all your treatment options. EPs want to free you from the burden of A-Fib.

Catheter Ablation Reduces Stroke Risk Even for Higher Risk Patients
by Steve S. Ryan, April 2015
In a study of nearly 38,000 people, patients with A-Fib who had a catheter ablation had about as many strokes as the people without A-Fib, while people on just medication had about twice as many strokes. (This isn’t a surprising finding. If you no longer have A-Fib, by definition you can’t have an A-Fib stroke.)
But what is surprising is that even patients at greater risk of stroke had a reduced stroke risk after catheter ablation. “Across all CHADS2 profiles and ages, A-Fib patients with ablation had a lower long-term risk of stroke compared to patients without ablation.” Even those at higher risks of stroke had a reduced risk of stroke.
Catheter Ablation Reduces Stroke Risk to That Of A Normal Person
And, more importantly, if someone had a catheter ablation, stroke risk decreased to that of a normal person. “A-Fib ablation patients had similar long-term risks of stroke across all CHADS2 profiles and ages compared to patients with no history of A-Fib.” “…freedom from A-Fib was the strongest predictor of stroke-free survival.”
Warfarin Not Needed After Successful Catheter Ablation
Some patients after a catheter ablation are still put on warfarin-for-life depending on their CHADS2 score. But research indicates that “A-Fib patients after ablation with moderate to high risk CHADS2 scores in which warfarin was discontinued do not show a higher risk of stroke compared to those in which warfarin is continued.”1
This study is medical breakthrough news, similar to another important study in which a successful catheter ablation reduced by 60% the expected rate of cardiovascular mortality. (See Live Longer—Have a Catheter Ablation.)
For anyone who has had a successful catheter ablation or who is thinking of having one, this study also is a game changer!
Even if you are at a theoretical high risk of stroke (high CHADS2), you don’t have to be on warfarin for the rest of your life after a successful catheter ablation. A successful catheter ablation reduces your stroke risk to that of a normal person (though obviously normal people do have strokes).
We already know that a catheter ablation significantly improves our well being. We certainly feel healthier in sinus rhythm. Few other medical procedures produce such a dramatic and nearly immediate improvement in our quality of life. This study confirms the long-term benefits of catheter ablation even for people who are sicker.
We don’t have to live a life on meds! A-Fib can be cured by a catheter ablation. And when you are made A-Fib free, not only do you feel better, but your risk of stroke is reduced to that of a normal person! This is terrific news for the A-Fib community.

Atrial Fibrillation patients often have loads of “Why?” and “How?” questions. Here are answers to the most frequently asked questions by patients and their families. (Click on the question to jump to the answer.)
1. Causes: “Why does so much Atrial Fibrillation come from the Pulmonary Vein openings?”
Related Question: “What causes Paroxysmal A-Fib to turn into Persistent (Chronic) A-Fib?”
Related Question: “A-Fib and Flutter—I have both. Does one cause the other?”
2. Hereditary: “Is my Atrial Fibrillation genetic? Will my children get A-Fib too?”
3. PSVT: “Is Atrial Fibrillation (A-Fib) different from what doctors call Paroxysmal Supraventricular Tachycardia?”
4. Adrenergic/Vagal: “What is the difference between “Adrenergic” and “Vagal” Atrial Fibrillation? How can I tell if I have one or the other? Does it really matter? Does Pulmonary Vein Ablation (Isolation) work for Adrenergic and/or Vagal A-Fib?”
5. Stiff Heart: “I’ve heard about ‘stiff heart’ or diastolic dysfunction. When you have A-Fib, do you automatically have diastolic heart failure? What exactly is diastolic dysfunction?”
6. Stem Cells: “I’ve read about stem cells research to regenerate damaged heart tissue. Could this help cure A-Fib patients?”
7. EF: “What is the heart’s ejection fraction? As an A-Fib patient, is it important to know my EF?”
8. Anesthesia: “I read that the local anesthesia my dentist uses may trigger my A-Fib. Why is that?”
9. Fibrosis: “How can I determine or measure how much fibrosis I have? Can something non-invasive like a CT scan measure fibrosis?”
10. Treatment Options: “My surgeon wants to close off my LAA during my Mini-Maze surgery. Should I agree? What’s the role of the Left Atrial Appendage?”
Related Question: “My cardiologist recommends a pacemaker. I have paroxysmal A-Fib with “pauses” at the end of an event. Will they stop if my A-Fib is cured? I am willing, but want to learn more about these pauses first.”
Related Question: “My EP won’t even try a catheter ablation. My left atrium is over 55mm and several cardioversions have failed. I am 69 years old, in permanent A-Fib for 15 years, but non-symptomatic. I exercise regularly and have met some self-imposed extreme goals. What more can I do?

2. “Did I cause my Atrial Fibrillation? Am I responsible for getting A-Fib?”
Most likely not.
We all remember our first attack of A-Fib—the shock, fear, confusion, the sense of something wrong in our body that we can’t control and the rushing to a doctor and/or emergency room.
Often there’s a tendency to blame ourselves, to feel guilt. We ask ourselves “What did I do—or not do—that caused my A-Fib?”
In general we are not responsible and didn’t cause our A-Fib. It’s different from a life-style related condition (like liver failure due to alcohol abuse).
Those newly diagnosed need to think of A-Fib as fate or karma or a life accident—rather than something we bring on ourselves. In life sometimes bad things happen to good people through no fault of their own. Think of A-Fib that way.
We need to keep saying to ourselves, “I am not responsible for my A-Fib. I did not cause my A-Fib,” like a chant or mantra whenever we start feeling guilt or blame for our A-Fib.

Return to Frequently Asked Questions
What are the Causes of A-Fib?
It’s estimated as many as 5.1 million people in the U.S. have A-Fib. By the year 2050, the number will be 12-16 million.1 Each year there are over 340,000 new cases in the US. A-Fib is the most common heart arrhythmia.2 In the U.S. people over 40 have a one in four lifetime risk of developing A-Fib.3
HOW DO YOU GET A-FIB?
If you’ve had other heart problems, this could lead to diseased heart tissue which generates the extra A-Fib pulses. Hypertension (high blood pressure), Mitral Valve disease, Congestive Heart Failure, coronary artery disease, and obesity6 seem to be related to A-Fib, possibly because they stretch and put pressure on the pulmonary veins where most A-Fib originates. Coronary artery disease reduces blood flow and oxygen (stagnant hypoxia) which can trigger A-Fib.
A lot of A-Fib seems to come from uncontrolled high blood pressure. Many EPs recommend that all hypertension patients get a home BP monitor and aggressively work at controlling their blood pressure.
About 25% to 35% of stroke survivors experience atrial fibrillation;7 Up to 40% of patients8 get A-Fib after open heart surgery. “Pericarditis”—inflammation of the pericardium, a sack-like membrane surrounding the heart—can lead to A-Fib.
Heavy drinking may trigger A-Fib, what hospitals call “holiday heart”—the majority of A-Fib admissions occur over weekends or holidays when more alcohol is consumed. No association was found between moderate alcohol use and A-Fib.9 (Heavy drinking reduces the ability of cells to take up and utilize oxygen [histotoxic hypoxia] which in some people may produce or trigger A-Fib. [Thanks to Warren Stuart for this insight.]) See the personal A-Fib story by Kris: “Binge Drinking Leads to Chronic A-Fib, Amiodarone Damages Eyesight” pp. 144-150 in my book, Beat Your A-Fib.
See the personal A-Fib story by Kris: “Binge Drinking Leads to Chronic A-Fib, Amiodarone Damages Eyesight” pp. 144-150 in my book, Beat Your A-Fib.
But if you already have A-Fib, even moderate use may trigger an A-Fib attack, “…people with atrial fibrillation had almost a four and a half greater chance of having an episode if they were consuming alcohol than if they were not.”10 (Thanks to David Holzman for calling our attention to this article.)
Otherwise healthy middle-aged women who consumed more than 2 drinks daily were 60% more likely to develop AF.11
Steve Walters writes “that red wine brings on A-Fib attacks for him, but not beer, white wine, or cordials. Has anyone else had similar experiences with red wine?” E-mail: bicwiley(at)gmail.com.
Neville writes that “taking a heavy dose of Magnesium/Potassium tablets and bananas for breakfast kept him out of A-Fib during a golfing weekend with significant drinking.” He uses the same strategy to get out of an A-Fib attack. firstname.lastname@example.org
Severe Body & Mind Stress
Severe infections, severe pain, traumatic injury, and illegal drug use can be a trigger. Low or high blood and tissue concentrations of minerals such as potassium, magnesium and calcium can trigger A-Fib. Thyroid problems (hyperthyroidism), lung disease, reactive hypoglycemia, viral infections and diabetes.
To learn the impact of anxiety and emotional stress on A-Fib, see Jay Teresi’s personal story “Anxiety the Greatest Challenge”
Extreme fatigue, anxiety and emotional stress can trigger A-Fib.
Smoking can trigger A-Fib. Smoking reduces the ability of the blood to carry oxygen (anemic hypoxia). Smoking cigarettes raises the risk of developing A-Fib even if one stops smoking, possibly because past smoking leaves behind permanent fibrotic damage to the atrium which makes later A-Fib more likely.12
As we put on pounds, our risk of developing A-Fib increases. In recent studies overweight adults were 39% more likely, and obese adults 87% more likely, to develop A-Fib than their normal-weight counterparts.13
Health problems linked to obesity, like high blood pressure and diabetes, can contribute to A-Fib. And obesity may put extra pressure on the pulmonary veins and induce A-Fib. Left atrial hypertension is a common finding in obese patients.
14 Do you have a parent or other immediate family member with A-Fib? Research says you have a 40% increased risk of developing A-Fib yourself. And the younger that family member was when they got A-Fib, the more likely you are to develop A-Fib.
According to Dr. Dan Roden of Vanderbilt University, genetic research may become important to A-Fib patients. He postulates that “Lone A-Fib” (A-Fib without a known cause) may actually be caused by genetics.
We’ve had reports that A-Fib can be triggered by antihistamines, bronchial inhalants, local anesthetics, medications such as sumatriptan, a headache drug,15 tobacco use, MSG, cold beverages and eating ice cream, high altitude, and even sleeping on one’s left side or stomach. One person writes that hair regrowth products seem to trigger his A-Fib.
I used to include caffeine (coffee, tea, sodas, etc.) in this list, but some research suggests that coffee and caffeine in moderate to heavy doses (2-3 cups to 10 cups/day) may not trigger or induce A-Fib.16 Coffee (caffeine) may indeed be antiarrhythmic and may reduce propensity and inducibility of A-Fib both in normal hearts and in those with focal forms of A-Fib.17
Possible Food-Related Triggers
Chocolate in large amounts may trigger attacks. Chocolate contains a little caffeine, but also contains the structurally related theobromine, a milder cardiac stimulant.
Another reader writes that the natural sweetener and sugar substitute Stevia seems to trigger her A-Fib.
GERD (heartburn) and other stomach problems (like H. pylori) may be related to or trigger A-Fib. If so, antacids and proton pump inhibitors like Nexium may help your A-Fib. A report from England suggests that the veterinary antibiotic “Lasalocid” found in eggs and poultry meat may cause or trigger A-Fib.18
Recent research indicates sleep apnea (where your breathing stops while you are sleeping) may contribute to A-Fib, probably by causing stress on the Pulmonary Vein openings and/or by depriving the lungs and body of adequate oxygen supply (Hypoxemic Hypoxia).
Over 25 million Americans currently have sleep apnea, but 80% of these people don’t know they have it
In one study of patients with A-Fib, 43% had sleep apnea. (An additional 31% had “central sleep apnea/Cheyne-Stokes respiration” which is a different type of sleep apnea.)19
If you have A-Fib, it’s wise to have yourself checked for sleep apnea. You can do a “quick” check of how much oxygen is in your blood with a Pulse Oximeter, such as the Contec Pulse Oximeter for about $20 from Amazon.com and in drug stores. A reading below 90% would indicate you need to have a sleep lab study.
You may want to check out the web site, MySleepApnea, http://www.myapnea.org, an online community for people with sleep apnea to s hare health info and personal experiences. (The Shaquille O’Neal video is terrific!)
Gail writes that “both her sleep apnea and her A-Fib were cured by a CPAP [Continuous Positive Airway Pressure] breathing machine.” (E-mail her: gail(at)bonairwine.com.)
Mechanically Induced A-Fib
Be careful if you work around equipment that vibrates. Certain frequencies and/or vibrations may possibly trigger or induce A-Fib. (If anyone has any info on how or why high frequencies and/or vibrations may possibly affect A-Fib, please let me know.)
Jerry writes that “high powered magnets, such as the N50, may trigger A-Fib due to the electromagnetic fields they generate.” (If you have any info on this, please email me.)
Physical and Gender Characteristics
Men get A-Fib more than women. But women may have more symptoms.
Men get A-Fib more than women. But women may have more symptoms.
Men get A-Fib more than women. But women fail more antiarrhythmic drugs therapies than men and may have more symptoms. For more see my article: The Facts About Women with A-Fib: Mother Nature and Gender Bias.
A-Fib is associated with aging of the heart. As patients get older, the prevalence of A-Fib increases, roughly doubling with each decade. 2-3% of people in their 60s, 5-6% of people in their 70s, and 8-10% of people in their 80s have A-Fib.21,22,23Approximately 70% of people with A-Fib are between 65 and 85 years of age.24 This suggests that A-Fib may be related to degenerative, age-related changes in the heart. Inflammation may contribute to the structural remodeling associated with A-Fib.25
No Known Cause
But in many A-Fib cases (around 50% of Paroxysmal A-Fib26), there is no currently discernible cause or trigger (called “Lone” or “Idiopathic A-Fib”).27 (Some research suggests that inflammation may initiate Lone A-Fib.)28
