BACKGROUND Evermine 50™ (Meril Life Sciences Pvt. Ltd., India) everolimus-eluting stent system (EES) is a novel ultrathin strut (50 µm) cobalt-chromium coronary drug-eluting stent (DES) platform with biodegradable polymer coating. The Evermine 50 EES-KLES study aimed to evaluate the Evermine 50 EES in terms of 24-month clinical safety and performance in patients with coronary artery disease (CAD). METHODS This retrospective study consisted of 171 patients (258 lesions) implanted with Evermine 50 EES for managing CAD. We analyzed the major adverse cardiac events (MACE) incidence, defined as a composite of cardiac death, myocardial infarction, and ischemia-driven target lesion revascularization (ID-TLR) at 6-, 12-, and 24-month follow-up. RESULTS A total of 171 patients were included with a mean age of 57.85 ± 10.05 years, of which, 139 (81.29%) were men, 69 (40.35%) were hypertensive, and 70 (40.94%) were diabetic. The incidence of MACE was 1 (0.58%), 3 (1.81%), and 4 (2.42%) at 6-, 12-, and 24-month follow-up, respectively. There were three cases (1.82%) of cardiac death and one case (0.61%) of ID-TLR up to 24 months. None of the patients was presented with definite or probable stent thrombosis (ST). CONCLUSION This study demonstrated that implantation of ultrathin strut Evermine 50 EES resulted in a low rate of incidence of MACE, indicating a favourable clinical safety and performance profile of Evermine 50 EES in patients with CAD [Clinical Trials Registry-India (CTRI) Number: CTRI/2017/09/009939)].
