Randomized trials have shown that implantation of sirolimus-eluting stents (SESs) and paclitaxel-eluting stents (PESs) reduce the incidence of major adverse cardiac events (MACEs) compared with bare metal stents. We compared the impact of SESs and PESs on clinical outcome in medically treated diabetic patients with multivessel stents. In this study, the in-hospital and 9-month clinical outcomes of 260 consecutive diabetic patients who underwent implantation of SESs (147 patients) or PESs (113 patients) were compared. MACEs were defined as death, nonfatal myocardial infarction, and clinically driven target vessel revascularization. The baseline demographic and angiographic characteristics were well matched. An average of 3.0 +/- 1.3 versus 2.8 +/- 1.2 lesions were treated in the SES and PES groups, respectively (p = 0.34), with a mean stented length per patient of 73 +/- 43 versus 61 +/- 36 mm (p = 0.08). No significant difference was observed between the SES and PES groups for in-hospital (6.1% vs 3.5%, p = 0.34) or 9-month MACE (24.5% vs 19.5%, p = 0.34) rates or for subacute (1.4% vs 0.9%, p = 0.72) or late (0.7% vs 0.9%, p = 0.85) stent thrombosis. Insulin-requiring diabetic patients treated with SESs and PESs also had similar demographic and angiographic characteristics and rates of in-hospital (4.7% vs 7.7%, p = 0.57) and 9-month (28.0% vs 38.4%, p = 0.44) MACEs. Insulin-dependent diabetes was the only independent predictor of MACEs (odds ratio 2.68, 95% confidence interval 1.46 to 4.89, p = 0.001). In conclusion, our results demonstrated a relatively high incidence of MACEs in a diabetic population with multivessel disease, despite treatment with drug-eluting stents. In addition, we could not find any clear advantage of 1 type of stent versus the other.
