Sudden Cardiac Death in Athletes

Sudden Cardiac Death in Athletes

Sudden cardiac death (SCD) in athletes is a rare but tragic complication of a number of cardiovascular diseases. Inherited causes such as the structural and arrhythmogenic genetic heart conditions are often found or suspected to be the underlying cause of death at post mortem examination. Physical activity and intense exercise may trigger cardiac arrhythmias in individuals with these conditions leading to SCD. Prevention and treatment strategies include individual athlete management strategies, coupled with public health measures such as universal cardiopulmonary resuscitation (CPR) training and availability of automatic external defibrillators (AEDs) in public places, thereby preventing SCD in both athletes and the general population. Where an athlete is known to have a cardiac condition, some restrictions from participation may be prudent, however, new evidence is emerging that perhaps current restrictions are too strict and could be relaxed in some cases. An athlete-centred model of care is essential to ensure the clinical implications and athlete preferences are balanced providing the best outcome for all concerned.

Sudden death due to catecholaminergic polymorphic ventricular tachycardia following negative stress-test outcome: genetics and clinical implications

This paper discusses the case of a young boy who died suddenly during a football match. The victim's personal and family medical histories were negative for cardiac events. He had undergone a cardiological investigation some months before his death, enabling him to participate in competitive sports. Only post-mortem molecular analysis allowed for a clearer determination of the most plausible cause of death, which was identified as inherited arrhythmogenic heart disease, known as catecholaminergic polymorphic ventricular tachycardia. It was possible to detect a novel, previously undescribed, variant in the RYR2 gene. This case report highlights the importance of a meaningful forensic multidisciplinary investigation in such cases, and also discusses possible medical malpractice claims.
