Background: Supraflex (Sahajanand Medical Technologies Pvt. Ltd, Surat, India) is a latest generation biodegradable polymer-coated sirolimus-eluting coronary stent designed on ultra-thin (60µm) cobalt-chromium platform with flexible ‘S-link’. Present study was designed to establish the safety and clinical performance of Supraflex in real-world Indian patients with coronary artery disease.
Methods: The study included total 839 consecutive patients with coronary artery disease, in whom Supraflex was implanted from January, 2014 to August, 2017 at six different tertiary care centres in India. Follow-up was received at 30 days, 6 months and 12 months after index procedure. The primary endpoint of the study was the incidence of major adverse cardiac events (MACE), a composite of cardiac death, myocardial infarction (MI), and target lesion revascularisation (TLR) at 12 months follow-up. The occurrence of stent thrombosis was analysed as safety endpoint.
Results: Total 1025 lesions were treated by implantation of 1098 Supraflex stents. At 12-month follow-up, 4.92% MACE was observed which included 7 (0.86%) cardiac deaths, 16 (1.97%) MI, and 17 (2.09%) TLR. There were only three incidences of stent thrombosis at 12 month follow-up.
Conclusion: The results of this study depicted excellent safety and clinical effectiveness of Supraflex in a high proportion of high risk real-world Indian patient with coronary artery disease.
