[Prolonged use of intravenous nitro derivatives in acute myocardial infarction (AMI)]

A retrospective survey is made on 166 cases of acute myocardial infarction, treated with intravenous nitro-derivatives for eight days of continuous therapy. This therapeutic modality appears to gain four goals: a reduction in mortality of patients, a faster return of ST tract on isoelectric guideline, fewer ventricular pump failures. In the authors' point of view, a delay in the downward return of ST tract towards the isoelectric guideline is an important but ominous prognostic sign in this group of patients. Therefore, this modality of treatment is suggested for all patients with AMI, wherever the myocardial coronary lesion is localized.
