title: [The role fo collateral circulation in the course of coronary heart disease: 10-year clinical and angiographic follow-up].
abstract: The paper presents the results of a 10-year prospective follow-up of 59 patients with coronary heart disease (CHD) concurrent with functional classes II-IV angina pectoris. Coronarography was made in all the patients whose coronary arteries and collateral blood flow were assessed. The experimental group comprised 37 patients with CHD and collateral circulatory insufficiency. The control group included 22 patients with effective collateral circulation. The experimental group showed a worse prognosis than did the control one. Myocardial infarction developed in 54 and 27% of cases, coronary heart disease mortality was 29.7 and 9% in the experimental and control groups, respectively. Effective collateral circulation is a prerequisite of successful surgical myocardial infarction.
