We sought to determine the rate of target vessel revascularization (TVR) after percutaneous transluminal coronary angioplasty (PTCA) and to determine factors that predispose to its occurrence. The 10-year outcome of 2,262 patients in the National Heart, Lung, and Blood institute PTCA Registry was analyzed to determine the incidence and characterize predictors of TVR. TVR was performed in 30.4% of patients. Male gender (relative risk [RR] 1.26; p <0.05), diabetes (RR 1.57; p <0.001), multiple discrete lesions (RR 1.38, p <0.01), diffuse lesions (RR 1.27; p <0.05), and calcium at the lesion site (RR 1.25; p <0.05) were predictors for TVR. TVR was performed early (< or = 1 year) in 18.3% and late (> 1 year) in 12.2%. Age > or = 65 years (RR 1.24; p <0.05), congestive heart failure (RR 1.70; p <0.05), acute coronary insufficiency (RR 1.28; p <0.05), and left anterior descending lesion location (RR 1.34, p <0.01) were significant predictors of early versus late TVR by multivariate analysis. Coronary artery bypass grafting (CABG) rather than PTCA was the TVR procedure in 21% of patients undergoing early TVR and 58% of those undergoing late TVR. Significant independent predictors of CABG as the TVR procedure were multivessel disease (RR 1.97; p <0.001), presence of collateral vessels (RR 1.81; p <0.05), diffuse (RR 1.89; p <0.01), or occluded (RR 1.82; p <0.05) target lesions, and a greater residual stenosis after the initial PTCA (RR 1.19; p <0.001). Age > or = 65 years (RR 0.65; p <0.05) conferred a lower risk for CABG. [ABSTRACT FROM AUTHOR]
