Abstract

Aims: Randomised trials indicate higher rates of stent thrombosis (ST) and target lesion failure (TLF) after percutaneous coronary intervention (PCI) with the Absorb bioresorbable scaffold (BRS) compared with modern drug-eluting stents (DES). We aimed to investigate the outcome of all Swedish patients treated with the Absorb BRS.<br />Methods and Results: The Absorb BRS (n=810) was compared with commonly used modern DES (n=67,909). The main outcome measure was definite ST; mean follow-up was two years. Despite being implanted in a younger, lower-risk population compared with modern DES, the Absorb BRS was associated with a higher crude incidence of definite ST at stent level: 1.5 vs. 0.6%, hazard ratio (HR) 2.38 (95% confidence interval [CI]: 1.34-4.23), adjusted HR 4.34 (95% CI: 2.37-7.94); p<0.001. The patient level adjusted HR was 4.44 (95% CI: 2.25-8.77). Rates of in-stent restenosis were similar for BRS and DES. Non-compliance with dual antiplatelet therapy (DAPT) guidelines was noted in six out of 12 BRS ST events. Three very late ST events occurred with the Absorb BRS.<br />Conclusions: In this real-world observational study, the Absorb BRS was associated with a significantly higher risk of definite ST compared with modern DES. Non-compliance with DAPT guideline recommendations was common among Absorb definite ST events.
