[Myocardial contractile function in ischemic heart disease patients who have had a myocardial infarct].
The results of the examination (electrocardiography, selective coronary arteriography, and left ventriculography) of 100 patients with ischemic heart disease and a history of myocardial infarction are discussed. All patients with postinfarction cicatricial changes in the myocardium of the anterior wall had severe affection (occlusion or stenosis by more than 75%) of the anterior interventricular branch of the left coronary artery, while 93% of patients with cicatricial changes in the myocardium of the inferior wall had affection of the right coronary artery. The parameters of myocardial contractility (ejection fraction, left ventricular and diastolic pressure, and Vmax) in patients with microfocal postinfarction cardiosclerosis both of the anterior and the inferior walls and in patients with macrofocal cardiosclerosis of the inferior wall remain within the lowest normal level. The contractility of the myocardium is sharply impaired in patients with macrofocal cardiosclerosis of the anterior wall and in those with combined cardiosclerosis of the anterior and inferior walls.
