[Ischemic episodes during daily activities and progression of ischemic heart disease].
In patients with coronary artery disease, ischemic episodes, the majority of which are silent, can be detected electrocardiographically during daily activities by Holter ambulatory monitoring. We here summarize our experience with the prognostic significance of such ischemic episodes, silent or symptomatic. In 356 patients the progression of ischemic heart disease was evaluated by clinical follow-up averaging 2 years. Death, infarction, unstable angina, referral for coronary bypass surgery or balloon angioplasty were significantly more common in those with ischemic episodes on Holter monitoring than in those without. Thus, in addition to the results of the treadmill exercise test and determinations of left ventricular ejection fraction, the appearance of ischemic episodes is also of prognostic significance.
