Emerging risk factors and the dose–response relationship between physical activity and lone atrial fibrillation: a prospective case–control study

Abstract

A history of ≥ 2,000 h of vigorous endurance training, tall stature, abdominal obesity, and OSA are frequently encountered as risk factors in patients with Ln-AF. Fewer than 2000 total hours of high-intensity endurance training associates with reduced Ln-AF risk.
