Popis: Introduction: In the era of drug-eluting stents, Bare Metal Stent (BMS) has worked its way up to be recognized in several indications. Moreover, literature suggests that strut thickness has been directly related to the restenosis rate. Aim: We intended to evaluate the clinical performance of the ultrathin (60 μm) Flexinnium stent (Sahajanand Medical Technologies Pvt. Ltd. Surat, India) for treatment of a wide range of patients with coronary artery disease in routine clinical practice. Materials and Methods: This was an observational, nonrandomized, retrospective, single-arm study carried out in realworld patients at three clinical centres of India. A total of 419 consecutive patients’ data was collected for the study, who underwent treatment for coronary lesions by implantation of Flexinnium stent, between April 2013 and December 2014. The primary endpoint of the study was Major Adverse Cardiac Events (MACE), a conglomerate of cardiac death, Myocardial Infarction (MI) (Q-wave and non-Q-wave), Target Lesion Revascularization (TLR) and Target Vessel Revascularization (TVR). Any incidence of Stent Thrombosis (ST) was also observed as safety endpoint. These endpoints were observed during in-hospital stay, at 30 days, six months and at 12 months follow up. All data were analysed using the Statistical Package for Social Sciences (SPSS; Chicago, IL, USA) program, version 15. Results: A total of 491 lesions were treated in 419 patients having mean age of 54.1 years. A total of 525 Flexinnium stents were implanted. There were 243 (58.0%) patients with hypertension. At 12 months the total incidences of MACE were 14 (3.5%). These included 9 (2.3%) cardiac deaths, 1 (0.3%) MI, 3 (0.8%) TLRs and 1 (0.3%) TVR. There was one incidence of definite ST at 12 months follow up. Conclusion: Our results demonstrate that the Flexinnium stent is associated with a low 12 months incidence of MACE in a wide range of real-world population. Long-term follow up would further confirm its clinical performance profile.
