Clinical features in patients with recurrent myocardial infarction.

A retrospective investigation of 420 patients who had survived the acute phase of myocardial infarction revealed 63 reinfarctions (in 57 patients) within three months. Twenty-eight patients died without reinfarction during the same period, and 335 survived three months without reinfarction. The reinfarction patients were significantly more often women, had more frequently a history of previous myocardial infarction and hypertension, and their myocardial infarctions were more often non-transmural and localized to the anterior wall of the heart. The ECG of each patient that was registered nearest prior to the reinfarction during hospitalization or prior to discharge showed more often negative T-waves.
