Abstract
A total of 112 hearts with limited local dilatation zones in coronary arteries (antiocclusion factor) selected from 500 patients dead from chronic forms of coronary heart disease were studied by postmortem contrast polypositional coronarography and cardiometry. A relationship between antiocclusion factor, on the one hand, and coronary artery stenosis and degree of vascularization of the left ventricular wall, on the other, was shown. The adaptation role of antiocclusion factor in coronary blood flow disorders caused by atherosclerotic obstruction (stenosis, occlusion, thrombosis) of the major coronary arteries was demonstrated. The incidence of antiocclusion factor in individual segments of coronary arteries depending on the type of atherosclerotic involvement and index of myocardial blood supply was determined.
