There are also some data involving exercise testing and coronary arteriography that link persons with silent myocardial ischemia to episodes of sudden death. In a study of Norwegian workers, Erikssen and Thaulow reported a nearly 0.5 percent yearly incidence of sudden death due to coronary artery disease in an asymptomatic population. Hickman et al reported a similar number in a study of US Air Force personnel. If one makes the assumption that there are at least 250,000 unexpected sudden deaths because of coronary artery disease in the United States, and at least 25 percent (approximately 60,000) have no prior clinical history of coronary artery disease, then at least 5,000 to 10,000 of these 60,000 individuals had totally asymptomatic silent myocardial ischemia. (This figure would represent […]
