Abstract

AMI : acute myocardial infarction ARVC : arrhythmogenic right ventricular cardiomyopathy BrS : Brugada syndrome CACS : coronary artery calcium score CAD : coronary artery disease ChD : Chagas heart disease CMR : cardiac magnetic resonance CPVT : catecholaminergic polymorphic ventricular tachycardia CTCA : computed tomography coronary angiography CV : cardiovascular DCM : dilated cardiomyopathy EAPCR : European Association for Cardiovascular Prevention and Rehabilitation HCM : hypertrophic cardiomyopathy LGE : late gadolinium enhancement LQTS : long QT syndrome LV/RV : left/right ventricle LVH : left ventricle hypertrophy NSVT : non-sustained ventricular tachycardia PPE : preparticipation evaluation PVC : premature ventricular contractions SCA/SCD : sudden cardiac arrest/death TTE : transthoracic echocardiography VF : ventricular fibrillation VT : ventricular tachycardia Sudden cardiac death (SCD) associated with athletic activity is a rare but devastating event. Victims are usually young and apparently healthy, and while many of these deaths remain unexplained, a substantial number of victims harbour an underlying and potentially detectable cardiovascular (CV) disease.1–4 The vast majority of these events are due to malignant tachyarrhythmias, usually ventricular fibrillation (VF) or ventricular tachycardia (VT) degenerating into ventricular fibrillation (VF), occurring in individuals with arrhythmogenic disorders (e.g. hypertrophic cardiomyopathy, arrhythmogenic cardiomyopathy, channelopathies). Intensive exercise training and competitive sport participation is a trigger that may favour insurgence of ominous ventricular tachyarrhythmias in predisposed individuals.5 Consequently, there is a great interest in early identification of at-risk individuals for whom appropriate treatment, followed or not by physical activity adjustment, may be implemented to minimize the risk of SCD. However, the role of pre-participation evaluation (PPE) in athletes as a feasible and efficient strategy to identify individuals at risk has remained controversial. …
