ABSTRACT
Objective To evaluate the safety and efficacy of overlapping sirolimus-eluting stent (SES) for long lesions during primary percutanous coronary intervention(PCl) in elderly patients with ST-segment elevation myocardial infarction (STEMI).Methods Seven hundred and seventy-five elderly patients with STEMI who underwent primary PCI were enrolled and followed up. Patients with two or more SES implanted for long lesions during PCI were taken as long lesion group and patients with single stents implanted were regarded as control group. The safety endpoints were in-hospital and follow-up death and stem thrombosis, and the clinical endpoints were the incidence of restenosis and target vessel revascularization rate during in-hospital follow-up and 6 months" follow-up.Results Among 775 patients, 62 patients had 64 long lesions. The average number of stents was 2. 2, and the average lesion length and stent length implanted were (45.3±10. 4)mm and (52.2±11.0)mm, respectively. During the 6 months' follow-up, the incidence of angiographically documented stent thrombosis were 1.6% in long lesion group and 1.1% in control group, respectively. No death or myocardial infarction occurred in two groups. There was no significant difference in the incidence of restenosis and target vessel revascularization rate between long-lesion group and control group (8. 1 vs. 4.8%, 6.9% vs. 3. 7%, both P>0.05). Conclusions Overlapping implantation of homemade SES is safe and effective for STEMI patients with long lesions in short-term period.
