Sirolimus-eluting stents compared with standard stents in the treatment of patients with primary angioplasty

Background Sirolimus-eluting stents have been shown to decrease restenosis and reintervention as compared with standard stents. We evaluated the use of sirolimus-eluting stents in primary percutaneous coronary intervention for acute myocardial infarction with ST-segment elevation. Methods We randomly assigned 120 patients to compare sirolimus-eluting stents with uncoated stents in primary percutaneous coronary intervention for acute myocardial infarction with ST-segment elevation. The primary end point was composite: death from cardiac causes, recurrent myocardial infarction, or target-lesion revascularization after 360 days. Results The rate of the primary end point was 6.7% in the sirolimus-eluting stent and 11% in the bare-metal stent group (relative risk 1.75, 95% Cl 0.47-6.57, P =.402). The survival free from target-vessel failure showed a higher trend in the sirolimus-eluting stent group than in the bare-metal stent group (0.0% vs 5.7%, P =.06,4). There was no significant difference between the 2 groups in the rate of death (5% and 3.6%, respectively, P =.736), reinfarction (1.7% and 1.8%, respectively; P =.940), or stent thrombosis (3.4% and 1.8%, respectively,- P =.62 1). Conclusions Among selected patients with acute myocardial infarction and ST-segment elevation, the use of sirolimus-eluting tents shows a trend to reduce the rate of target-vessel revascularization in comparison with bare-metal stent.
