Risk of Cardiac Arrest During Sports Low for Fit Middle-Aged
(HealthDay News) — Physically active middle-aged men and women have little chance of experiencing sudden cardiac arrest (SCA) while participating in sports, according to a new study published online April 6 in Circulation.
Sumeet Chugh, MD, associate director of genomic cardiology at the Cedars-Sinai Heart Institute in Los Angeles, and colleagues reviewed 1,247 cases of SCA among middle-aged adults from the Oregon Sudden Unexpected Death Study. Patients' average age was 51. The authors looked to see how many SCAs occurred during physical activity (sexual activity was not included).
Of the 5% of cases that occurred during exercise, more than one-quarter took place while jogging. Basketball and cycling accounted for fewer than one in five sports-related SCAs. More than one-third had symptoms of cardiovascular disease, such as chest pain or dyspnea, in the week before their SCA, and more than half had risk factors for cardiovascular disease.
Sports participation made it more likely the person would be seen and treated, the researchers found. Close to 90% of sports-associated SCAs were witnessed – often because they occurred at a gym or other public place – vs. roughly half of those that occurred at other times. Those people were also more likely to receive cardiopulmonary resuscitation – 44 vs. 25%. Moreover, fit men and women were more likely to survive than unfit individuals (23 vs. 14%). "Overall, the news is good. The risk of dying suddenly if you participate in sports is quite low," Chugh told HealthDay.
