Safety and Efficacy of Ultra-Thin, Biodegradable Polymer Coated Sirolimus-Eluting Supralimus-Core Stents in Real-World Patients: Outcomes at 24-Month Follow-Up

摘要

Aim: The purpose of this registry was to establish long-term safety and efficacy through implantation of Supralimus-Core sirolimus-eluting stents (SES) in real-world patients with coronary artery disease (CAD). Methods: The present registry was a retrospective, singe-arm, single-centre, investigator-initiated registry. A total of 372 consecutive patients were implanted with Supralimus-Core SES between January 2015 and November 2016. The primary endpoints were major adverse cardiac events (MACE), a composite of cardiac death, myocardial infarction (MI), target lesion revascularization (TLR) and target vessel revascularization (TVR) at 24 months. The secondary endpoints were all-cause death and all separate components of the primary endpoint. Additional endpoints included events of stent thrombosis classified as definite, probable, and possible stent thrombosis. Follow-ups were conducted at 30-days, 6-months, 12-months and 24-months after the index procedure. Results: The mean age of the registry population was 56.3 ± 11.1 years. Males constituted 276 (74.2%) patients. Hypertensives, diabetics, alcoholics, tobacco chewers and smokers comprised 198 (53.2%), 160 (43.0%), 93 (25.0%), 91 (24.5%) and 88 (23.7%) of the registry population, respectively. The mean length and diameter of stents implanted was 19.3 ± 8.8 mm and 2.9 ± 0.3 mm, respectively. At the 24-month follow-up, MACE was reported in 14 (3.8%) patients. Cardiac death, MI, TLR and TVR was reported in 7 (1.9%), 4 (1.1%), 3 (0.8%) and 4 (1.1%) patients, respectively. Overall stent thrombosis occurred in 4 (1.1%) patients. Conclusions: The low MACE rate of 3.8% at the 24-month follow-up indicates favorable long-term results after implantation of the ultra-thin strut Supralimus-Core SES in all-comer, real-world patients.
