Myocardial infarction without chest pain occurs in high incidence in elderly. However, the pathophysiological significance of the silent ischemia is still unknown. To elucidate the significance of the "painless" symptom during myocardial ischemia induced by exercise, we analyzed the incidence of silent ischemia on treadmill tests and attempted to examine the severity of the coronary stenosis in such painless subjects. ⋯ Painless ischemia during the treadmill test was found in high incidence in the elderly. Painless ischemia must be treated as same as ischemia with chest pain.
