Outcomes of Acute Myocardial Infarction Patients Implanted With Biodegradable Polymer Biolimus-Eluting Stents Versus New-Generation Durable Polymer Drug-Eluting Stents: A Retrospective Analysis.

Abstract

We compared outcomes between biodegradable polymer biolimus-eluting stent (BP-BES) and new-generation durable polymer drug-eluting stent (DP-DES) implantations in patients with acute myocardial infarction (MI). Among 13472 patients with acute MI in a nationwide registry, 557 (64.8%) were in the BP-BES and 303 (35.2%) in the new-generation DP-DES group following coronary reperfusion. The occurrence of major adverse cardiac events (MACE; death, MI, revascularization) and stent thrombosis was compared. Major adverse cardiac events occurred in 53 (6.2%) patients and showed similar rates between the BP-BES and new-generation DP-DES groups (all: 6.6% vs 5.9%, P = .652; propensity score [PS] matched: n = 380, 6.3% vs 5.3%, P = .623). Stent thrombosis did not differ between groups (all: 0.3% vs 0.4%, P = .892; PS matched: 0.5% vs 0.5%, P = 1.000). Major adverse cardiac event-free survival was comparable between groups (all: 93.4% vs 94.1%, log-rank P = .357; PS matched: 93.7% vs 94.7%, log-rank P = .445). Biodegradable polymer biolimus-eluting stent was not associated with MACE (all: hazard ratio [HR], 1.67; 95% confidence interval [CI], 0.75-3.74; P = 0.212; PS matched: HR, 1.05; 95% CI, 0.40-2.75; P = .915). In conclusion, in patients with acute MI, BP-BES was equivalent to the new-generation DP-DES in terms of outcomes.
