Quitting Smoking Reduces Risk of Atrial Fibrillation in Long-Time Smokers

Even long-time smokers can significantly reduce their risk of developing atrial fibrillation by quitting smoking, according to a recent study published in the American College of Cardiology’s journal “JACC: Clinical Electrophysiology”.

Atrial fibrillation is a serious heart condition associated with an increased risk of stroke, heart failure, and death. Smoking is a major risk factor for atrial fibrillation, but the study found that quitting smoking can help prevent its development.

Study Findings

The study analyzed the smoking habits of 146,700 people who currently smoke or have smoked and followed their health status for 12 years. The results showed that those who quit smoking had a significantly lower incidence of atrial fibrillation compared to those who continued to smoke.

Specifically, the study found that those who quit smoking during the study period had an 18% reduction in atrial fibrillation. This suggests that quitting smoking can have a positive impact on cardiovascular health, even for long-time smokers.

Understanding the Relationship Between Smoking and Atrial Fibrillation

While previous studies have investigated the relationship between smoking and atrial fibrillation, this study provides new insights into the potential causal link between the two. According to Dr. Gregory Marcus of the University of California, San Francisco, the finding of a lower incidence of atrial fibrillation in those who quit smoking suggests a possible causal relationship between smoking and atrial fibrillation.

Further research is needed to fully understand the mechanisms by which smoking increases the risk of developing atrial fibrillation. However, the study’s findings emphasize the importance of quitting smoking to reduce the risk of atrial fibrillation and other cardiovascular diseases.
