- Original description
Earlier studies have shown a dose-dependent relationship between alcohol intake and incident atrial fibrillation (AF) as well as a causal link with several risk factors for AF such as hypertension, obesity and sleep apnea. However, the effect of drinking (alcohol) on post-ablation outcome such as arrhythmia recurrence, quality of life (QoL) and cognitive function in AF patients is unclear. Therefore, we aim to find the answer for a very frequently asked question, "is it safe to continue drinking alcohol (at the pre-ablation level) following catheter ablation OR should the intake be reduced for better outcome?", in this randomized trial.Read full original descriptionShow less
Impact of Post-ablation Alcohol Intake on Arrhythmia Recurrence, Quality of Life and Cognition in Patients With Atrial Fibrillation
Earlier studies have shown a dose-dependent relationship between alcohol intake and incident atrial fibrillation (AF) as well as a causal link with several risk factors for AF such as hypertension, obesity and sleep apnea. However, the effect of drinking (alcohol) on post-ablation outcome such as arrhythmia recurrence, quality of life (QoL) and cognitive function in AF patients is unclear. Therefore, we aim to find the answer for a very frequently asked question, "is it safe to continue drinking alcohol (at the pre-ablation level) following catheter ablation OR should the intake be reduced for better outcome?", in this randomized trial.
Inclusion: AF patients that regularly consume >5 alcoholic drink (*12 g of pure alcohol/drink)/week; Paroxysmal or persistent AF; First catheter ablation History of alcohol-induced arrhythmia; Willing to sign the written informed consent.
Exclusion: Psychiatric conditions; Patients with established dementia; LVEF <35%; Binge drinkers (alcohol dependence); Non-drinkers; MoCA score ≤ 17 on Montreal Cognitive Assessment (MoCA); Medically unstable patients (acute/unstable or poorly controlled problems that would demand focused, relatively urgent or emergent medical attention); Unwilling for alcohol-abstinence; Long-standing persistence AF; Patient under legal protection; Pregnancy.
