ABSTRACT
The impact of postinfarction angina pectoris on the course of myocardial infarction (MI) was studied in the hospital setting in 359 patients who had sustained large MI, 247 of them being followed for a year after their discharge. In the group of patients with postinfarction angina pectoris, the course of the disease was found to be more severe in hospital and during a year-follow-up after MI. They more frequently developed acute and chronic heart failure, rhythm and conduction disturbances, recurrent MI. A statistic relationship was not established between the development of postinfarction angina and late fatality. Postinfarction angina was demonstrated to increase a risk for an unfavorable course of a postinfarction period. No significant difference was found in the prognostic significance of the time angina occurred following MI.

The course of acute posterior diaphragmatic myocardial infarction (MI) was evaluated in 82 in-patients, with 47 of those followed up after the discharge. The patients were divided into 2 groups: those without and with ST depression in precordial ECG leads (groups 1 and 2, respectively). MI took a more severe course in the second group. Heart failure and high-grade ventricular extrasystoles were significantly more common both in and after hospital in such patients. Atrioventricular blocks, cardiogenic shock and recurrences during hospital stay prevailed in the second group. After the discharge, they showed a higher mortality rate and significantly more frequent exacerbations of coronary disease, including all cases of repeated macrofocal MI. This suggests that patients with posterior-diaphragmatic MI and ST depression in precordial ECG leads have a poorer immediate and long-term prognosis and can be designated a high-risk group.
