[Assessment of antiischemic efficacy of balloon angioplasty, coronary bypass surgery and conservative therapy after myocardial infarction in patients with single coronary artery disease. Three year prospective study].
Efficacy of balloon angioplasty, coronary bypass surgery and conservative therapy in postmyocardial infarction patients with single coronary artery disease was assessed in 3 year prospective study. Positive clinical effect persisted after coronary artery bypass grafting (CABG) in 78 and 73% of patients and after balloon angioplasty in 60 and 40% of patients in 1 and 3 years, respectively. Significant decreases of number of anginal attacks (by 94.1 and 74.1%, respectively), nitroglycerin consumption (by 93.6 and 74.8%, respectively) and dimensions of ischemic perfusion defects (by 68.8 and 33.7%, respectively) were observed 1 year after both CABG and angioplasty. Lowering of exercise tolerance (by 11.1%), increase of nitroglycerin consumption (by 15.8%) and worsening of myocardial perfusion (by 9%) were observed after 3 years in conservatively treated patients.
