Abstract
Drug-eluting stents (DES) have been shown in randomized trials to reduce clinical events in diabetic patients. Our aim was to determine whether these clinical results are applicable in an unselected population of patients with non-insulin-dependent diabetes mellitus (NIDDM) and insulin-dependent diabetes mellitus (IDDM). We studied 440 consecutive patients (271 NIDDM and 169 IDDM) who underwent percutaneous coronary intervention, divided into 2 cohorts: Group A (1998-2000): 220 patients with bare metal stents, and Group B (2002-2004): 220 patients with drug-eluting stents. We analyzed major coronary adverse events (death, nonfatal acute myocardial infarction, and target lesion revascularization) over a mean follow-up of 18+/-15 months. Group B had more patients who were insulin-dependent (44.5 versus 32.3% p<0.001) or had hypertension (64.5 versus 54.1%; p=0.02), a lower left ventricular ejection fraction (53.89 versus 56.8%; p=0.04), more complex lesions (B2/C) (82.7 versus 62.3%; p<0.001), more treated lesions (1.40 versus 1.26; p<0.001), more stents implanted (1.69 versus 1.15; p<0.0001), and more patients treated with abciximab (76.8 versus 42.7%; p<0.0001). During the follow-up, Group B had fewer major adverse coronary eve...Continue Reading
