Nonstructural Genetic Cardiac Disease as the Most Common Cause of Sudden Cardiac Death in the Young Athlete: Is This True?

AbstractPurpose  of reviewThis review is aimed at summarizing and discussing the primary causes of sudden cardiac death (SCD) in young athletes.Recent findingsSCD in young athletes is a dramatic event, with an incidence rate that can reach 13 deaths per 100,000 athletes. Occasionally, exercise can trigger SCD, and unfortunately, this event may be the first manifestation of an underlying and silent cardiac condition. In the USA, hypertrophic cardiomyopathy is reported as the leading cause of SCD among young athletes, whereas arrhythmogenic right ventricular cardiomyopathy has been reported as the main cause in the Veneto region of Italy. However, emerging evidence has demonstrated that in many cases, athletes who experience sudden death have a seemingly normal cardiac structure, suggesting the possibility of sudden arrhythmic death syndrome. In recent decades, it has been possible to determine the causes of many SCDs that occur in the presence of nonstructural cardiac diseases. It is worth noting that routinely used cardiovascular screening methods, such as electrocardiogram and echocardiogram, may fail to detect nonstructural genetic cardiac diseases. In turn, in some circumstances, genetic testing may play a role in identifying individuals at risk of SCD due to these conditions.SummaryUnderstanding the underlying causes of SCD in young athletes is noteworthy for developing effective prevention and screening strategies. A multidisciplinary approach involving cardiologists, c...
