objective: To identify independent clinical and angiographic predictors determining early outcomes following coronary stent implantation. Methods: Nine hundred and forty six patients with a mean age of 61.04 ± 10.98 years (31 to 91 years of age) underwent stent implantation; 580 were males (61.3%). Procedural success was defined when a patient had at least one vessel successfully dilated with a residual stenosis < 20%. Clinical success occurred when the procedure was successful and no major

... lications occurred (MI, need for CABG, or death) during the hospital stay. Clinical and angiographic characteristics were analyzed. All variables related to early outcomes as assessed by the univariate analysis were included in the logistic regression model. results: Procedural success was achieved in 98.9%, clinical success in 95.7%, uncomplicated unsuccessful outcomes occurred in 0.1%, and major complications in 4.2%. The multivariate analysis showed that restenotic lesion, calcification, and irregular contour were related to procedural success. Diabetes mellitus, cardiogenic shock, acute coronary syndromes, age, left ventricular dysfunction, calcification, and total occlusion were predictors of clinical success. Diabetes mellitus, cardiogenic shock, acute coronary syndromes, age, multivessel disease, left ventricular dysfunction, calcification, long lesions, and total occlusion were predictors of major complications, whereas cardiogenic shock, acute coronary syndromes, age, hypertension, and left ventricular dysfunction were predictors of in-hospital mortality. conclusion: Our results suggest that the early outcomes following stent implantation were significantly related to cardiogenic shock, left ventricular dysfunction, age, calcification, and total occlusion.
