[The left coronary artery in ischemic heart disease patients (data from 2-dimensional echocardiography)].
Two-dimensional echocardiography was used to study the state of the proximal part of the left coronary artery (LCA) in 106 males: 39 patients after anterior myocardial infarction, 28--after posteroinferior myocardial infarction, 11 patients with angina pectoris without infarction, and 28 healthy persons. The comparison of the results of coronary radiography and echocardiography in 21 patients showed that the sensitivity and specificity of echocardiography in the diagnosis of stenosis of the left main coronary artery was 80 and 100%, respectively. Methods of assessment of echographic density of the LCA walls on the basis of comparison of their density with echographic density of the walls of the aorta and aortic valve showed that in the CHD patients LCA wall density was increased as compared to that of the healthy persons, and in the patients after anterio myocardial infarction it was increased as compared to that of the healthy persons and other CHD patients. The method permitted the detection of an increase in LCA wall echographic density which was typical of arterial atherosclerosis, and the assessment of a degree of arterial wall atherosclerotic density.
