Evolution of coronary insufficiency after coronary artery bypass grafting in post-myocardial infarction patients: Results prospective follow-up for five years

Post-myocardial infarction patients with multivessel coronary artery stenos es were prospectively followed-up for 5 years after coronary artery bypass grafting (CABG). Characteristics of the state of coronary vascular bed, of microcirculation in the ischemic myocardium, and of central hemodynamics we re correlated with peculiarities of angina development, dynamics of cardiac pump function and exercise tolerance. Myocardial perfusion scintigraphy wi th thallium-199 showed that transient perfusion defects increased during fo llow up from 4,5+/-11,0 to 10,8+/-1,6% (p<0,01). Patients with exercise tol erance less than 50 W after CABG significantly more often (p<0,01) had low (<1,0 mmol/l) high density lipoprotein cholesterol.
