do endurance sports cause heart disease

Summary

Chronic extreme exercise training and competing in endurance events can lead to heart damage and rhythm disorders, as evidenced by biomarkers associated with heart damage found in marathon runners' blood samples 1 , as well as myocardial fibrosis, atrial fibrillation, an exercise-induced acquired form of arrhythmogenic right ventricular cardiomyopathy, ventricular arrhythmias, and coronary atherosclerosis. 2 People with genetic risk factors are especially vulnerable.
