Abstract
The clinical and prognostic significance of the direction of the S-T segment shift on the 12-lead electrocardiogram was evaluated in medically treated patients with unstable angina pectoris. Long-term mortality and morbidity of 11 patients with transient S-T segment elevation (group I) were compared to that of 21 patients with transient S-T segment depression (group II). The average follow-up duration was 62 months. There was no significant difference between groups I and II with respect to survival or nonfatal myocardial infarction over a five-year period. Mortality was related to the extent of coronary artery disease and left ventricular ejection fraction rather than to the direction of the S-T segment shift.
