Sudden cardiac death (SCD) during physical exercise is devastating. We aimed to evaluate causes and circumstances of exercise-related SCD in the young in Australia. We reviewed the National Coronial Information System database for deaths in Australia relating to cardiovascular disease in cases aged 10-35 years between 2000-2016. Included cases had undertaken physical exercise at time of event. We collected demographics, circumstances of death, type of physical exercise, bystander cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) use prior to ambulance arrival. Over a 17-year period, 1,925 SCD cases were identified of which 110 cases (6%) (median age 27 years [interquartile range [IQR] 21-32 years], 92% male) were related to sports/physical exercise. Thirteen cases (12%) occurred in active athletes. Most common causes were coronary artery disease (CAD; 37%) and sudden arrhythmic death syndrome (SADS; 20%). Amongst Aboriginal and Torres Strait Islanders (n=10), all deaths were related to CAD. Australian Rules Football (24%), running/jogging (14%) and soccer (14%) were the most frequent physical exercise activities. Prior symptoms were present in 39% (chest pain 37%, presyncope/syncope 26%). Most were witnessed (87%) with bystander CPR in 70%. AED use prior to ambulance arrival was 8%. This study demonstrates the high occurrence of CAD and SADS in SCD in the young related to physical exercise. Aboriginal and Torres Strait Islanders were disproportionately affected by CAD. Although events were commonly witnessed, AED was seldom used prior to ambulance arrival and highlights an important opportunity to improve outcomes in the post-arrest chain of survival.
