Sudden death during exertion is extremely rare. Among adults older tha
n 30, coronary artery disease is the predominant cause of sudden death
. Attention to risk factors and premonitory symptoms is the best preve
ntion. Doing the appropriate testing, tailoring exercise programs, and
discouraging denial help minimize the risk. But above all, physicians
can help keep patients' fears in check so as not to deprive patients
of the unquestionable benefits of exercise.
