Arrhythmias and structural remodeling in lifelong and retired master endurance athletes.

ABSTRACT:

Background

A greater prevalence of arrhythmias has been described in endurance athletes, but it remains unclear whether this risk persists after detraining. We aimed to evaluate the prevalence of arrhythmias and their relationship with cardiac remodeling in lifelong and retired master endurance athletes compared to non-athletic controls.

Methods

We performed a cross-sectional analysis of observational studies that used echocardiography and cardiac magnetic resonance to detail cardiac structure and function, and Holter monitors to identify atrial and ventricular arrhythmias in 185 endurance athletes and 81 non-athletic controls aged ≥40 years. Athletes were categorized as active lifelong (n = 144) or retired (n = 41) based on hours per week of high-intensity endurance exercis
