AIMS: The role of drug-eluting stent (DES) remains an unsettled issue in patients with ST-segment elevation myocardial infarction (STEMI). Therefore, we performed a meta-analysis of randomised trials to evaluate the clinical outcome of DES as compared with bare-metal stent (BMS) after percutaneous coronary intervention (PCI). METHODS AND RESULTS: We undertook a literature search until July 2009. Thirteen clinical trials met inclusion criteria, with 7,244 patients enrolled. Up to 1-year, patients treated with DES as compared with BMS experienced less target-vessel revascularisation (TVR) (5.11% versus 11.19% respectively, p<0.00001) and recurrent myocardial infarction rates (3.03% versus 3.70% respectively, p=0.02). In addition, no significant differences were found in terms of cardiac death (2.80% versus 3.52%, p=0.21) and stent thrombosis (2.65% versus 2.76%, p=0.37). Using the adjusted indirect comparison, a significant difference between sirolimus- and paclitaxel-eluting stent was found when TVR was evaluated (OR [95% CI] =0.59 [0.40-0.89], p=0.01), without differences in other clinical outcomes. CONCLUSIONS: In patients undergoing PCI for STEMI, treatment with DES is associated with decreased TVR and myocardial infarction rates, without increasing cardiac death or stent thrombosis occurrence. Sirolimus-eluting stent is associated with a greater TVR reduction as compared to paclitaxel-eluting stent.

Abstract

AIMS: The role of drug-eluting stent (DES) remains an unsettled issue in patients with ST-segment elevation myocardial infarction (STEMI). Therefore, we performed a meta-analysis of randomised trials to evaluate the clinical outcome of DES as compared with bare-metal stent (BMS) after percutaneous coronary intervention (PCI). METHODS AND RESULTS: We undertook a literature search until July 2009. Thirteen clinical trials met inclusion criteria, with 7,244 patients enrolled. Up to 1-year, patients treated with DES as compared with BMS experienced less target-vessel revascularisation (TVR) (5.11% versus 11.19% respectively, p<0.00001) and recurrent myocardial infarction rates (3.03% versus 3.70% respectively, p=0.02). In addition, no significant differences were found in terms of cardiac death (2.80% versus 3.52%, p=0.21) and stent thrombosis (2.65% versus 2.76%, p=0.37). Using the adjusted indirect comparison, a significant difference between sirolimus- and paclitaxel-eluting stent was found when TVR was evaluated (OR [95% CI] =0.59 [0.40-0.89], p=0.01), without differences in other clinical outcomes. CONCLUSIONS: In patients undergoing PCI for STEMI, treatment with DES is associated with decreased TVR and myocardial infarction rates, without increasing cardiac death or stent thrombosis occurrence. Sirolimus-eluting stent is associated with a greater TVR reduction as compared to paclitaxel-eluting stent.
