RESUMO
INTRODUCTION: Diabetes mellitus (DM) is a major risk of cardiovascular events. Bioresorbable stent frame materials capable of providing mechanical support and drug-delivery functions have been developed in an attempt to improve long-term outcomes. However, publications about the long-term outcomes of bioresorbable scaffolds (BRS) in DM patients are still limited. The aim of this study was to investigate the long-term safety and efficacy of BRS between patients with and without diabetes. METHODS: Data regarding BRS placement in consecutive patients receiving percutaneous coronary interventions were collected from the cardiovascular center of a single tertiary medical center from 2014 to 2017. RESULTS: A total of 138 cases were included and followed up for 4 years. The mortality rate was 1.1% in the non-diabetic group and 4.1% in the diabetic group (p = 0.2542). No cardiac mortality was observed. One patient had an acute myocardial infarction (0.7%) in the non-diabetic group. The rate of target lesion revascularization was 3.4% in the non-diabetic group and 4.08% in the diabetic group. The ratio of target vessel revascularization was 6.74% in the non-diabetic group and 4.1% in the diabetic group. CONCLUSIONS: This study demonstrated no significant difference in long-term outcomes after BRS implantation between patients with and without diabetes in a single tertiary medical center.
