Alcohol appears to have an immediate—or near-immediate—effect on heart rhythm, significantly increasing the chance that an episode of atrial fibrillation (AFib) will occur, according to new data presented at the American College of Cardiology's 70th Annual Scientific Session.

 

The data revealed that just one glass of wine, beer or other alcoholic beverage was associated with twofold greater odds of an episode of AFib occurring within the next four hours. Among people having two or more drinks in one sitting, there was a more than threefold higher chance of experiencing AFib. Using an alcohol sensor placed on participants' ankles, which passively monitored alcohol intake, the investigators found that every 0.1% increase in inferred blood alcohol concentration over the previous 12 hours was associated with an approximate 40% higher odds of an AFib episode. Evidence from those sensors also demonstrated that the total alcohol concentration over time also predicted the chance AFib would occur.

 

"Alcohol is the most commonly consumed drug in the world, and there is still a lot we don't understand about what it does to our bodies and, in particular, our hearts," said Gregory M. Marcus, MD, cardiologist and professor of medicine at the University of California, San Francisco, and the study's lead author. "Based on our data, we found that alcohol can acutely influence the likelihood that an episode of AFib will occur within a few hours, and the more alcohol consumed, the higher the risk of having an event."

 

AFib is the most common heart rhythm disorder. It is often characterized by a rapid, chaotic and fluttery heartbeat. Marcus said that people can experience a range of symptoms. Some may not feel anything, while others are overcome with severe shortness of breath, fatigue, fainting or near fainting spells and a disconcerting sensation that the heart is beating out of control. AFib also results in costly use of health care services, including visits to the emergency department, hospitalizations and procedures each year. Over time, AFib can lead to heart failure, stroke and dementia if untreated.

 

Researchers enrolled 100 patients with paroxysmal or intermittent AFib, which tends to go away within a short period of time (unlike chronic AFib). Patients in the study were 64 years old on average; the majority were white (85%) or male (80%). Past medical history, medications and lifestyle habits were assessed through chart reviews and patient interviews.

 

Each participant was fitted with a wearable heart monitor that continuously tracked their heart rhythm and an ankle sensor to objectively detect when more than two to three drinks were consumed on a given occasion. Participants were asked to press a button on the heart monitor each time they had an alcoholic drink. Finger stick blood tests measuring alcohol consumption in the previous few weeks were also used to corroborate self-reported drinking events. Because researchers used repeated measurements from the same individual, they served as their own control over time. Overall, more than half (56) had an episode of AFib during the four-week study.

 

"Patients have been telling us that alcohol is a trigger for AFib for a long time, but it's been hard, if not impossible, to study because there is a critical temporal relationship that requires a real-time assessment of alcohol intake and heart rhythm," Marcus said. "This is the first study to objectively demonstrate and quantify the real-time relationship between alcohol consumption and AFib episodes. While this study was limited to people with intermittent AFib, it's reasonable to extrapolate the fact that in many people alcohol may be the main trigger for an initial episode."

 

Marcus said there may be other factors—such as race/ethnicity, sex, genetics or other environmental exposures—that influence alcohol's effect on the heart in various ways and need to be studied. In addition, people often pair alcohol with foods that are high in sodium, while some pour a drink because they feel stressed, so there may be other things that play a role. The findings also run counter to previous reports about the potentially protective role of alcohol on heart health when used in moderation.

 

"There is conventional wisdom that alcohol is 'good' or 'healthy' for the heart, based on observational studies, but that relates to coronary heart disease and heart attack. These new data present an interesting conundrum regarding the overall risks versus benefits of alcohol in moderation," Marcus said. "But the data is very clear that more is not better when it comes to alcohol; those who drink more have a higher risk of heart attack and death."

 

Marcus added that this situation is a perfect example where precision medicine may play a clinically relevant role to help identify which patients are at high risk for alcohol-related AFib. Those who are not at high-risk of the harmful effects of alcohol might yet benefit from moderate alcohol consumption as another way to potentially protect them from coronary blockages and disease.

 

The general recommendation for daily alcohol consumption is no more than one standard alcoholic beverage a day for women and two for men.

 

"Still, when patients ask me what they can do to avoid an AFib episode, I tell them the evidence suggests that they should minimize, if not completely eliminate, alcohol. But we have to consider quality of life as well, which is both relevant to arrhythmia symptoms and the opportunity to enjoy a glass of wine once in a while for some. So, it's not as simple as instructing everyone to avoid alcohol," Marcus said.

 

As far as next steps, Marcus and his team will look at how these results, which are limited to those with intermittent AFib, may apply to the general population. They also hope to identify other factors that may influence the relationship between alcohol and AFib, including genetics.

Heart Disease

    
Atrial Fibrillation


What is atrial fibrillation?


Atrial fibrillation, often called AFib or AF, is the most common type of treated heart

arrhythmia. An arrhythmia is when the heart beats too slowly, too fast, or in an irregular

way.


When a person has AFib, the normal beating in the upper chambers of the heart (the

two atria) is irregular, and blood doesn’t flow as well as it should from the atria to the

lower chambers of the heart (the two ventricles). AFib may happen in brief episodes, or

it may be a permanent condition.
Atrial Fibrillation is the most common type of heart arrhythmia. AFib occurs when the

upper chambers and lower chambers are not coordinated, causing the heart to beat too

slowly, too quickly, or irregularly.


Facts About AFib

    It is estimated that 12.1 million people in the United States will have AFib in 2030.1,2
    In 2019, AFib was mentioned on 183,321 death certificates and was the underlying

cause of death in 26,535 of those deaths.3


    People of European descent are more likely to have AFib than African Americans.
    Because the number of AFib cases increases with age and women generally live

longer than men, more women than men experience AFib.


What are the symptoms of AFib?


Some people who have AFib don’t know they have it and don’t have any symptoms.

Others may experience one or more of the following symptoms:


    Irregular heartbeat
    Heart palpitations (rapid, fluttering, or pounding)
    Lightheadedness
    Extreme fatigue
    Shortness of breath
    Chest pain


What are the risk factors for AFib?


The risk for AFib increases with age. High blood pressure, the risk for which also

increases with advancing age, accounts for about 1 in 5 cases of AFib.4


Risk factors for AFib include4,5

    Advancing age
    High blood pressure
    Obesity
    European ancestry
    Diabetes
    Heart failure
    Ischemic heart disease
    Hyperthyroidism
    Chronic kidney disease
    Moderate to heavy alcohol use
    Smoking
    Enlargement of the chambers on the left side of the heart


How is AFib related to stroke?

 

AFib increases a person’s risk for stroke. When standard stroke risk factors were

accounted for, AFib was associated with an approximately fivefold increased risk of

ischemic stroke.6 AFib causes about 1 in 7 strokes.7


Strokes caused by complications from AFib tend to be more severe than strokes with

other underlying causes. Strokes happen when blood flow to the brain is blocked by a

blood clot or by fatty deposits called plaque in the blood vessel lining.
How is AFib treated?


Treatment for AFib can include

    Medicines to control the heart’s rhythm and rate

    Blood-thinning medicine to prevent blood clots from forming and reduce stroke risk

    Surgery

    Medicine and healthy lifestyle changes to manage AFib risk factors


What are the consequences of AFib?

More than 454,000 hospitalizations with AFib as the primary diagnosis happen each

year in the United States.4 The condition contributes to about 158,000 deaths each

year.3 The death rate from AFib as the primary or a contributing cause of death has

been rising for more than two decades.7


Cardiac Dysrhythmia hospitalization rates for fee-for-service Medicare beneficiaries

ages 65 and older were highest in counties in the Northeastern, Eastern, and

Southeastern United States.
