Abstract

Background—: Sports-associated sudden cardiac arrests (SCAs) occur mostly during middle age. We sought to determine the burden, characteristics, and outcomes of SCA during sports among middle-aged residents of a large US community. Methods and Results—: Patients with SCA who were 35 to 65 years of age were identified in a large, prospective, population-based study (2002–2013), with systematic and comprehensive assessment of their lifetime medical history. 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 (95% confidence interval, 8.1–35.4) per 1 million per year. The incidence varied significantly by sex, with a higher incidence among men (relative risk, 18.68; 95% confidence interval, 2.50–139.56) for sports SCAs compared with all other SCAs (relative risk 2.58; 95% confidence interval, 2.12–3.13). Sports SCA was also more likely to be a witnessed event (87% versus 53%; P <0.001) with cardiopulmonary resuscitation (44% versus 25%; P =0.001) and ventricular fibrillation (84% versus 51%; P <0.0001). 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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
