Background: The first generation drug eluting stents (DES) coated with a permanent polymer reduced the rates of restenosis when compared to bare metal stents (BMS). The present study was conducted to compare strut biodegradable polymer sirolimus-eluting stent (BP-SES) versus the durable polymer everolimus-eluting stent (DP-EES) in patients with myocardial infarction. Materials & Methods: The present study was conducted on 84 cases of myocardial infarction of both genders. Patients were divided into 2 groups of 42 each. Group I patients received thin strut biodegradable polymer sirolimus-eluting stent (BP-SES) and in group II patients received durable polymer everolimus-eluting stent (DP-EES). Results: The mean stents used per patients was 1.53 in group I and 1.52 in group II, maximum implantation pressure was 14.21 in group I and 14.30 in group II, direct stent implantation was seen in 34.2 % in group I and 36.1% in group II, post- dilatation was seen in 24.1% in group I and 27.6% in group II, thrombectomy was observed in 10.4% in group I and 10.2% in group II. The difference was significant (P< 0.05). Mortality was observed 6 in group I and 7 in group II. Conclusion: Authors found both strut BP-coated sirolimus-eluting stent (BP-SES) and the durable coating everolimus-eluting stent (DP-EES) were equally effective in patients with myocardial infarction.
