"Methods and Results—Patients with SCA who were 35 to 65 years of age . . . Of the 1247 SCA cases, 63 (5%) occurred during sports activities at a mean age of 51.1±8.8 years, yielding an incidence of 21.7 . . . per 1 million per year. . . . Survival to hospital discharge was higher for sports-associated SCA (23.2% versus 13.6%; P=0.04). Sports SCA cases presented with known preexisting cardiac disease in 16% and ≥1 cardiovascular risk factors in 56%, and overall, 36% of cases had typical cardiovascular symptoms during the week preceding the SCA.
Conclusions—Sports-associated SCA in middle age represents a relatively small proportion of the overall SCA burden, reinforcing the idea of the high-benefit, low-risk nature of sports activity. Especially in light of current population aging trends, our findings emphasize that targeted education could maximize both safety and acceptance of sports activity in the older athlete."
