Atrial fibrillation (AFib), the most common heart rhythm disorder, affects millions worldwide. Recent research highlights alcohol as a significant trigger for AFib episodes, even in small amounts. Studies suggest that consuming just one drink can increase the likelihood of an AFib episode, potentially doubling the risk within hours.

In recognition of American Heart Month, Aspirus Health is focusing on raising awareness about alcohol's impact on heart rhythm and advising those with AFib to consider eliminating it from their lifestyle.

"AFib occurs when the upper chambers of the heart, the atria, quiver instead of contracting properly, which can lead to heart failure, stroke, and even early death," said John Johnkoski, MD, Cardiothoracic Surgeon at Aspirus Heart Care. "Alcohol creates a chemical environment in the heart that makes AFib more likely, and studies show there really is no safe level of alcohol for people with this condition."

For individuals already diagnosed with AFib, alcohol consumption can prolong episodes and interfere with medications. It also increases the risk of stroke and heart failure. Over time, continued drinking may weaken the heart and contribute to more persistent forms of AFib.

"We used to think alcohol only caused heart problems with excessive drinking, but now we know that even small amounts can negatively impact AFib," Dr. Johnkoski explained. "Avoiding alcohol gives you the best chance of staying in rhythm, whether you’re managing it with medications, catheter-based therapies, or surgery."

Dr. Johnkoski emphasizes that while everyone’s AFib triggers may vary, quitting alcohol remains the safest option. "If someone is willing to stop drinking, that's fantastic—that's a win," he said. "If they're hesitant, we might frame the conversation around testing whether alcohol is a trigger for them. But the reality is studies show there's no truly safe level of alcohol for people with AFib."

To maintain a stable heart rhythm effectively involves avoiding alcohol entirely. Symptoms such as a racing heart or dizziness after drinking should prompt immediate cessation and consultation with a doctor if they persist or worsen.

Aspirus Health encourages those with AFib or concerns about their heart health to consult healthcare providers about managing their condition and reducing risk factors.
