Abstract
OBJECTIVES: This study aimed to assess the clinical impact of strut width (evaluated by abluminal strut surface area [ASSA]) on periprocedural myocardial infarction (PMI) and clinical outcomes in patients treated with bioresorbable scaffolds (BRS) versus first-generation sirolimus-eluting stents (SES). BACKGROUND: To date, there are no reports on the impact of ASSA on PMI and clinical outcomes. METHODS: We compared the impact of ASSA on outcomes and PMI in propensity-matched patients treated with BRS and SES. The primary outcome was the incidence of major adverse cardiac events (MACE), defined as the combination of all-cause mortality, follow-up myocardial infarction, and target vessel revascularization, at 30-days and 1-year follow-ups. The secondary endpoint was the incidence of PMI. RESULTS: After propensity-matched analysis, 499 patients (147 BRS patients vs. 352 SES patients) were evaluated. Mean ASSA was higher in patients treated with BRS versus SES (BRS: 132.3 ± 76.7 mm(2) vs. SES: 67.6 ± 48.4 mm(2), p < 0.001). MACE was not significantly different between groups (30-days MACE: BRS: 0% vs. SES: 1.4%, p = 0.16, and 1-year MACE: BRS: 15.7% vs. SES: 11.4%, p = 0.67). The incidence of PMI was significantly higher in the BRS group (BRS: 13.1% vs. SES: 7.5%, p = 0.05). Multivariable analyses indicated that treatment of left anterior descending artery and ASSA were independent predictors of PMI. CONCLUSIONS: BRS implantation, compared with SES implantation, was associated with a higher incidence of PMI. MACE at 30 days and 1 year were not significantly different. Left anterior descending artery percutaneous coronary intervention and ASSA were independent predictors of PMI.
