[Immediate and long-term prognosis of sub-endocardial infarct].
A comparison is conducted of two groups of patients with myocardial infarction: one group of 77 patients with subendocardial myocardial infarction (SEMI) and another of 166 patients with transmural myocardial infarction (TMI). In-hospital mortality, ventricular arrhythmias and a-v blocks are higher in TMI. Late follow-up (mean: 43 months) shows, however, that after discharge SEMI shows a higher mortality and more angina and recurrences of myocardial infarction that TMI. These results, and the ECG localization of the MI recurrences, suggest that SEMI usually reflects severe coronary artery disease.
