[Myocardial infarction in early postoperative complications in operations of myocardial revascularization: incidences, clinical study and mechanisms].

A study of the electrocardiograms and enzyme levels after surgery to revascularise the myocardium in a group of 174 consecutive patients has allowed us to demonstrate 19 cases of early postoperative myocardial infarction (EPOMI) (10.9%). 10 of these cases had no clinical features of EPOMI; 9 had clinical signs (collapse of altered systemic pressures, arrhythmias) or haemodynamic disorders (raised left atrial pressure).
