Alcohol as a Modifiable Risk Factor for Atrial Fibrillation

Rövid összefoglaló (regiszter, angolul)

Atrial fibrillation (AF) is the most common arrhythmia, diagnosed in approximately 50 million people worldwide. Its prevalence is expected to increase, eventually affecting every third person, which will result in significant healthcare costs. AF symptoms include palpitations, shortness of breath, and fatigue. The condition may lead to discomfort from symptoms and medical treatment, reduced quality of life, and an increased risk of heart failure, stroke, and death. High alcohol intake can cause AF, trigger new episodes and worsen the condition. The aim of this project is to determine the effect of six months of alcohol abstinence after atrial fibrillation ablation, as modifiable risk factors have gained more attention in the prevention and treatment of AF. Secondly, this study will provide new insights into utilizing a technology platform that enables wearable devices to collect health data remotely. This approach makes ready-to-wear devices a simple and effective solution for monitoring patients' health from home. The study is designed as an open-label, pragmatic, prospective, 1:1 Randomized Controlled Trial (RCT) that will be preceded by a feasibility study (n=40) that will test the feasibility of the proposed inter-vention for the RCT study. The intervention consists of six months of alcohol abstinence after the ablation procedure. To ensure the best possible chance to succeed with complete alcohol absti-nence, the patients will be offered guidance and support from nurses at the hospital based on the techniques of motivational interviewing. After evaluating the outcomes of the feasibility study, appropriate adjustments will be made. All participants from the feasibility study will be included in the RCT study. The study will include a total of 414 participants. The feasibility will be evaluated in five main objec-tives according to the Medical Research Council guidance for designing and evaluating complex in-terventions: Recruitment, data collection, acceptability, resources spent and participant responses. The primary outcome of the RCT study is AF recurrence after 6 months measured with Withings Scanwatch 2. Secondary outcomes are Number of days with AF, change in AUDIT score, change in symptom burden (AFSS score), change in health-related quality of life (EQ-5D-5L), change in alcohol consumption (self-reported and Peth analysis), change in antiarrhythmic medicine and sick leave days. Part two of the study will investigate the long-term effect of alcohol abstinence after atrial fibrilla-tion ablation. Primary outcome is time to AF and secondary outcome is re-ablations, hospital admis-sions and antiarrhythmic therapy. Lastly, a cost-utility analysis will be performed.
