Abstract
Retained graft patency after revascularization lowers risk of subseque nt myocardial infarction or death. Patients who have surgical rather t han medical therapy are far less Likely to die of a subsequent nonperi operative infarction. Both myocardial infarction size and lethality ar e modified by prior coronary artery bypass grafting, The procedure ris k for either death or nonfatal infarction remains higher in coronary a rtery bypass grafting than in angioplasty, but among patients who surv ive for 30 days, subsequent risk is only two-thirds that of patients w ho had angioplasty. Better graft patency rates are associated with the use of an internal thoracic artery rather than a saphenous vein, larg er size of the recipient coronary artery, and better blood flow throug h the grafts. Aspirin therapy clearly decreases the occlusion rate per distal anastomosis, but aprotinin therapy arrears to have little or n o effect on graft patency, Numerous other factors can influence graft patency. Prominent among the factors increasing risk for requirement o f a reoperation are nonuse of an internal thoracic artery, incomplete revascularization, and continued cigarette smoking.
