Abstract

Objectives:

We explored the 12-month clinical outcome of the titanium-nitride-oxide-coated OPTIMAX stent based on cobalt-chromium platform.Background: The OPTIMAX stent demonstrated a satisfactory 6-month clinical outcome in de novo coronary lesions.Methods: We enrolled 224 consecutive symptomatic patients with significant (50%) stenosis in de novo coronary lesions, who were treated with OPTIMAX stent implantation. The primary endpoint was major adverse cardiac events at 12-month follow-up, defined as a composite of cardiac death, non-fatal myocardial infarction (MI), or ischemia-driven target lesion revascularization (TLR). Stent thrombosis was adjudicated according to the definition of the Academic Research Consortium.Results: The mean age of the cohort was 67 ± 8 years (75% males). Patients presented with acute coronary syndrome in 62.1%. Radial access was used in 92%; complex (type B and C) lesions were treated in 79.9%. Both procedural and clinical success occurred in 100% of the cases. The mean follow-up period was 366 ± 22 days. At 12-month follow-up, the primary endpoint occurred in 14 (6.3%) patients. Cardiac death occurred in three (1.3%) patients, non-fatal MI in seven (3.1%) patients, and ischemia-driven TLR in seven (3.1%) patients. No definite stent thrombosis occurred.Conclusions: In the current prospective observational study, implantation of the OPTIMAX stent demonstrated an adequate 12-month clinical outcome, with a low rate of major adverse cardiac events, and no stent thrombosis. © 2015 Wiley Periodicals, Inc.
