Relation of transient silent ischemic episodes to daily activities
Abstract:
In patients with coronary disease, asymptomatic ST segment depression during daily life is a reliable indicator of silent myocardial ischemia and is the most frequent form of ischemia in both symptomatic and asymptomatic patients. Silent ischemic episodes usually occur during activities not ordinarily thought to be ischemia provoking, and not necessarily with the same frequency, duration, or magnitude as painful episodes and may be the only type of ischemia detected in some patients. Some features suggest an important reduction in myocardial oxygen supply, in addition to an increase in demand, as a mechanism for silent ischemic episodes occurring during daily life.
