Abstract

Aims: Bioresorbable scaffolds (BRS) were conceived to ensure transient coronary artery support during antiproliferative drug delivery. However, the Absorb everolimus-eluting bioresorbable scaffold was found to be inferior to everolimus-eluting metallic stents (EES) in moderately complex coronary anatomies. We sought to investigate whether the Absorb represents a valuable option for the percutaneous treatment of patients with ST-elevation myocardial infarction (STEMI). Methods and results: We pooled the individual patient data of two randomised trials specifically designed to investigate the performance of Absorb versus EES in patients with acute myocardial infarction (MI). The primary outcome was lesion (in-segment) diameter stenosis at angiographic follow-up. The main secondary outcome was the device-oriented composite endpoint (DOCE) of cardiac death, target vessel MI and target lesion revascularisation at one year. A total of 388 patients with STEMI were allocated to Absorb (n=227) or EES (n=161). Angiographic follow-up at one year was available for 332 (85.6%) patients. Lesion diameter stenosis was comparable between Absorb and EES (22.8±9.8% versus 23.6±11.2%; mean difference -0.8%, 95% confidence interval [CI]: -3.18-1.48, p=0.47). DOCE occurred in 21 patients at one year, with similar distribution between the Absorb and EES groups (5.3% versus 5.6%; hazard ratio 0.95, 95% CI: 0.40-2.26, p=0.91). Conclusions: This pooled analysis provides evidence for a comparable angiographic performance and suggests similar clinical performance of Absorb and EES in STEMI patients undergoing percutaneous revascularisation. The long-term durability of Absorb and the extent to which newer BRS platforms might have a potential role in STEMI deserve further investigation.
