- Background: Despite improved long-term safety of biodegradable polymer (BP) drug-eluting stents (DES)
compared to first-generation durable polymer (DP) DES, data on the safety and efficacy of BP-DES compared with
second-generation (2G) DP-DES in patients with acute myocardial infarction (AMI) are limited.
Hypothesis: To evaluate the safety and efficacy of BP-DES compared with 2G-DP-DES in the higher stent
thrombosis (ST) risk setting of AMI.
Methods: A total of 3359 AMI patients who received either BP-DES (n=261) or 2G-DP-DES (n=3098) were
included from the Korea Acute Myocardial Infarction Registry (KAMIR). Differences in baseline clinical and
angiographic characteristics were adjusted using a 1:5 propensity score matching analysis (n=261 for BP-DES
and n=1305 for 2G-DP-DES). The primary outcome was the incidence of major adverse cardiac events (MACE)
including all-cause death, recurrent myocardial infarction (re-MI), and target vessel revascularization (TVR). The
rate of definite or probable ST was also investigated.
Results: In adjusted analysis, there was no significant difference between the 2 groups in baseline clinical
and angiographic characteristics; 2-year MACE (10.7% and 9.9% in the BP-DES group and 2G-DP-DES group,
respectively, P = 0.679); ST incidence (0.8% vs 0.9%, respectively, P = 1.0), and rates of all-cause death, re-MI,
and TVR. By multivariate analysis, old age, diabetes mellitus, renal dysfunction, and left ventricular dysfunction
were the independent predictors of MACE after BP-DES or 2G-DP-DES implantation.
Conclusions: BP-DES and 2G-DP-DES appear to have comparable 2-year safety and efficacy for the treatment of
AMI. However, longer-term follow-up is needed.
