Abstract:
Heavy alcohol consumption is an established risk factor for atrial fibrillation (AF). However, the association between habitual changes in heavy habitual drinkers and incident AF remains unclear. The aim of this study was to evaluate whether absolute abstinence or reduced drinking decreases incident AF in heavy habitual drinkers. Methods and results Atrial fibrillation-free participants with heavy alcohol consumption registered in the Korean National Health Insurance Service database between 2005 and 2008 were enrolled. Habitual changes in alcohol consumption between 2009 and 2012 were classified as sustained heavy drinking, reduced drinking, and absolute abstinence. The primary outcome measure was new-onset AF during the follow-up. To minimize the effect of confounding variables on outcome events, inverse probability of treatment weighting (IPTW) analysis was performed. Overall, 19 425 participants were evaluated. The absolute abstinence group showed a 63% lower incidence of AF (IPTW hazard ratio: 0.379, 95% confidence interval: 0.169–0.853) than did the sustained heavy drinking group. Subgroup analysis identified that abstinence significantly reduced incident AF in participants with normal body mass index and without hypertension, diabetes, dyslipidaemia, heart failure, stroke, chronic kidney disease, or coronary artery disease (all P-value & lt;0.05). There was no statistical difference in incident AF in participants with reduced drinking compared with sustained heavy alcohol group. Conclusion Absolute abstinence could reduce the incidence of AF in heavy alcohol drinkers. Comprehensive clinical measures and public health policies are warranted to motivate alcohol abstinence in heavy drinkers. Lay summary
