The long-term clinical impact of polymer-free sirolimus-eluting stents (PF-SES) in unselected patients undergoing percutaneous coronary intervention (PCI) still remains poorly investigated. We studied the long-term clinical impact of PF-SES in a large cohort of unselected patients receiving PCI therapy at two tertiary care centers in India.A total of 3213 patients received PCI with drug-eluting stents during the period from December 2004 to September 2011. Among these, those receiving PF-SES implantation were retrospectively included in this registry. The primary endpoint in our study was the occurrence of major adverse cardiac events (MACE), defined as the composite of death/myocardial infarction (MI) and target lesion revascularization, whereas the main secondary endpoints were cardiac death/MI and definite/probable stent thrombosis.A total of 1213 patients (83.8% men, 31.8% diabetics) with 1658 lesions (52.5% B2/C, according to the American College of Cardiology/American Heart Association classification) were studied. After a median follow-up of 1160 days, MACE occurred in 10.0% of patients, whereas the rates of cardiac death/MI and definite/probable ST were found to be 5.4 and 1.9%, respectively. The incidence of MACE was more common in patients aged at least 65 years [hazard ratio (HR)=1.69, 95% confidence interval (CI)=1.13-2.52, P=0.01] and diabetics (HR=1.71, 95% CI=1.18-2.47, P=0.004). The incidence of cardiac death/MI was more common in patients aged at least 65 years (HR=2.21, 95% CI=1.32-3.70, P=0.003). The baseline risk profile did not impact the occurrence of target lesion revascularization.In this large cohort of unselected PCI patients treated in India, PF-SES shows a sustained safety and efficacy at long-term follow-up.     «
