TL;DR: A meta-analysis of genome-wide association studies on atrial fibrillation among 14,710 cases and 373,897 controls from Iceland and 14,792 cases and 393,863 controls from the UK Biobank, focusing on low frequency coding and splice mutations, finds an association with a missense variant in MYZAP and a component of the intercalated discs of cardiomyocytes.

Associations between physical activity, left atrial size and incident atrial fibrillation: the Tromsø Study 1994–2016

TL;DR: Moderate PA was associated with reduced AF risk, and PA attenuated the increased risk of AF with LA enlargement in both men and women and all age groups.

Journal ArticleDOI

TL;DR: The study indicates that mental health problems among individuals with myocardial infarction, atrial fibrillation and stroke may have started to develop several years before the cardiovascular event and suggests that successful CVD rehabilitation may need to consider previous life factors.
