Highlights the potential for chronic pro-arrhythmic right ventricular remodeling and 'exercise-induced cardiomyopathy' in highly trained endurance athletes.
Supports potential exercise-induced cardiomyopathy in endurance athletes; hypothesis-generating and should not yet change practice.
Several studies have described the adaptive remodeling of the heart during exercise. In some more practiced endurance athletes, there is a disproportionate load on the right ventricle (RV), at least during exercise, and this might be the basis for a chronic pro-arrhythmic RV remodeling. Especially, in these kinds of athletes the recovery after detraining might be incomplete, in particular for RV changes. The observation of acute myocardial injury based on transient elevation of biomarkers and chronic myocardial scar, not completely reversible changes of the RV and an increased prevalence of some arrhythmias support the existence of an "exercise-induced cardiomyopathy." The aim of this paper is to review current knowledge about changes in the right heart in highly trained athletes and how these change influence cardiac function.
