Modifying Lifestyle for Long-Term Atrial Fibrillation Control: Choice of Diet, Physical Activity, Alcohol Consumption, and Quitting Smoking
Reducing Alcohol Intake Key to Lowering Atrial Fibrillation Risk
Managing atrial fibrillation (AFib), a common type of heart arrhythmia, involves adopting a healthy lifestyle. One crucial aspect is limiting alcohol consumption.
Excessive alcohol intake is a known trigger for irregular heart rhythms and increases the risk of AFib recurrence. In fact, research shows that reducing alcohol intake, especially complete abstinence in heavy drinkers, significantly lowers the long-term risk of developing AFib.
Heavy and binge drinking worsen cardiac health by causing irregular heart rhythms, elevated blood pressure, and alcohol-related cardiomyopathy, which increase AFib risk over time. Even moderate alcohol consumption can trigger AFib episodes and increase arrhythmia risk.
For people already diagnosed with AFib, even small amounts of alcohol substantially increase arrhythmic episodes, so abstinence or strict limitation is advised.
The Mediterranean diet, rich in omega-3 fatty acids, has been shown to improve heart health and reduce the frequency of AFib episodes. Regular exercise, emphasising moderate-intensity aerobic activities like walking, cycling, and swimming, can help decrease the AF burden.
A healthy diet, focusing on nutrient-dense foods and minimising processed foods, is also beneficial. Maintaining balanced electrolyte levels and quitting smoking can further help regulate heart rhythm and manage AFib.
It's important to note that atrial fibrillation is the predominant cardiac aetiology of stroke. Due to its uneven rhythm, blood flow through the heart becomes turbulent, significantly increasing the likelihood of thrombus (blood clot) formation.
Individuals who quit smoking exhibit a 30% diminished risk of ischemic stroke and a 16% reduction in all-cause mortality, regardless of oral anticoagulation status. Regular exercise is essential for managing AFib as it improves cardiovascular health, reduces obesity, lowers blood pressure, and enhances overall well-being.
If you have or are at risk for AFib, these findings highlight the importance of limiting alcohol to prevent recurrent episodes and reduce long-term complications related to atrial fibrillation. Always consult a healthcare provider for personalized advice.
Risk factors for AFib include advancing age, hypertension, pre-existing cardiac and pulmonary conditions, congenital heart anomalies, and elevated alcohol intake. The consumption of one drink per day potentially elevates the risk of AF considerably. Physical exercise may reduce some atrial fibrillation risks linked to obesity.
Atrial fibrillation may be paroxysmal (lasting fewer than seven days) or chronic (lasting more than seven days). AF is the predominant form of heart arrhythmia.
