Abstract
The subjects who underwent diagnostic coronarography and detailed examination included 274 patients with lesions in the left coronary artery and its branches and 50 subjects without pathological changes in the coronary arteries or left ventricle. The authors also examined 149 patients with unchanged coronary arteries (67 with “small vessel disease” 42 with cardiomyopathy of various etiology; and 40 with other pathologies, such as the WPW syndrome, arterial hypertension, aortic stenosis, etc.). In addition to routine retrograde left heart catheterization and recording of the hemodynamic parameters demonstrated by ventriculography, the coronary blood flow was measured in all patients. Its normalized (specific) values are a basis for the coronary blood flow quantification in normal subjects, patients with the coronary heart disease (with insufficient oxygen supply to the myocardium), and those with cardiomyopathy of various genesis (when the myocardial oxygen demand increases together with the left ventricular myocardium mass).
