Review Meta Analysis Comparative Study
Drug-eluting vs bare-metal stents in primary angioplasty: a pooled patient-level meta-analysis of randomized trials.
Concerns have emerged regarding a higher risk of stent thrombosis after drug-eluting stent (DES) implantation, especially in the setting of ST-segment elevation myocardial infarction (STEMI). Our objective was to perform a meta-analysis using individual patient data to evaluate the long-term safety and effectiveness of DES compared with bare-metal stents (BMS) in patients undergoing primary percutaneous coronary intervention for STEMI. ⋯ The present pooled patient-level meta-analysis demonstrates that among patients with STEMI undergoing primary percutaneous coronary intervention, sirolimus-eluting and paclitaxel-eluting stents compared with BMS are associated with a significant reduction in target-vessel revascularization at long-term follow-up. Although there were no differences in cumulative mortality, reinfarction, or stent thrombosis, the incidence of very late reinfarction and stent thrombosis was increased with these DES.
