Transient ST-segment Elevation with Postmyocardial Infarction Angina: Prognostic Significance

Fifty-seven patients with acute myocardial infarction were observed for early postmyocardial infarction angina and associated transient ST-segment changes. Nine patients had postinfarction angina with transient ST-segment elevation (group 1), seventeen patients had postinfarction angina with ST-segment depression or no ST-segment changes (Group 2), and 31 patients had no postinfarction angina (Group 3). The patients in Group 1 had a statistically significant increased incidence of early reinfarction and death, when compared with the other two groups, singly or combined. There was no significant difference in the incidence of reinfarction and death when Group 2 is compared with Group 3. Patients with transient ST-segment elevation associated with early postmyocardial infarction angina may be an appropriate group in whom to consider newer, more aggressive modes of postinfarction management.
