[Prognostic significance of the area of myocardial lesion and the status of the coronary bed during restoration of work capacity in patients with a complicated course of acute myocardial infarction].
The effect of heart failure and acute left-ventricular aneurysm on the recovery of working capacity was assessed with reference to the size of necrotic focus and the extent of coronary arterial involvement in 117 patients with acute myocardial infarction. The size of necrotic focus and magnitude of coronary arterial affection were shown to be the principal determinants of heart failure in acute myocardial infarction. The presence of heart failure and acute left-ventricular aneurysm in combination with multiple coronary-arterial lesions is an adverse predictive sign in the assessment of the severity of acute myocardial infarction and the recovery of patients' working capacity. On the contrary, the presence of a local aneurysm in combination with an isolated coronary-arterial lesion should not be regarded as an unequivocal indicator of disability.
