Abstract:
BACKGROUND AND OBJECTIVES: The comparison of long-term clinical effects between Sirolimus-eluting stent (SES) and Paclitaxel-eluting stents (PES) for treatment of acute myocardial infarction (AMI) remains unclear. Seeking to clarify this issue, we performed a retrospective analysis to evaluate four-year clinical outcomes of SES compared to PES treated AMI patients. SUBJECTS AND METHODS: From January 2004 to August 2006, all patients with acute ST-segment elevation myocardial infarction and acute non-ST segment elevation myocardial infarction who underwent percutaneous coronary intervention (PCI) by implantation of either SES or PES were enrolled. The occurrences of cardiac and non-cardiac deaths, recurrent infarction, target vessel revascularization (TVR) and stent thrombosis were analyzed. The composite end points of these major adverse cardiac events (MACE) were also analyzed. RESULTS: During the study period, a total of 668 AMI patients had visited, of which 522 patients (299 with SES and 223 with PES) were enrolled. During the four-year clinical follow-up, both groups showed similar occurrences of non-cardiac death (14.6+/-2.2% vs. 18.3+/-3.0%, p=0.26); cardiac death (6.8+/-1.52% vs. 11.2+/-2.6%, p=0.39); re-infarction (3.3+/-1.1% vs. 6.4+/-1.8%, p=0.31); and stent thrombosis (3.2+/-1.1% vs. 5.4+/-1.7%, p=0.53). However, occurrences of TVR {4.0+/-1.2% vs. 10.0+/-3.0%, hazard ratio (HR)=0.498, 95% confidence interval (CI)=0.257-0.967, p=0.039} and MACE (19.4+/-2.5% vs. 29.4+/-3.5%, HR=0.645, 95% CI=0.443-0.940, p=0.021) were significantly lower in the SES population. CONCLUSION: In AMI patients treated with either SES or PES implantation, the former had a significantly lower risk of TVR and MACE during four-year clinical follow-up. Rates of death, cardiac death or recurrent infarction, and stent thrombosis were similar.
