Comparison of Durable-Polymer- and Biodegradable-Polymer-Based Newer-Generation Drug-Eluting Stents in Patients with Acute Myocardial Infarction and Prediabetes After Successful Percutaneous Coronary Intervention.
INTERNATIONAL HEART JOURNAL
Hyperglycemia is an important risk factor for poor clinical outcomes in patients with acute myocardial infarction (AMI). The relative superiority of the long-term clinical outcomes of durable-polymer (DP)-based and biodegradable-polymer (BP)-based newer-generation drug-eluting stents (DESs) after successful percutaneous coronary intervention (PCI) in patients with AMI and prediabetes is not well established. We compared the clinical outcomes in such patients between DP-based and BP-based newer-generation DESs.
A total of 4,377 patients with AMI and prediabetes were divided into the following two groups: the DP-DES group (n = 3,775; zotarolimus-eluting stents [ZES; n = 1,546] and everolimus-eluting stents [EES; n = 2,229]) and the BP-DES group (n = 602; biolimus-eluting stents [BES]). The primary endpoint was the occurrence of major adverse cardiac events (MACEs), defined as all-cause death, recurrent myocardial infarction (re-MI), or any repeat revascularization. The secondary endpoint was the occurrence of stent thrombosis (ST).
The 2-year adjusted hazard ratio (aHR) of MACEs for ZES versus EES, ZES versus BES, EES versus BES, and ZES/EES versus BES (aHR: 1.125; 95% confidence interval [CI], 0.834-1.518; P = 0.440) were similar. The cumulative incidence of ST was also comparable between the DP-DES and BP-DES groups (aHR: 1.407; 95% CI, 0.476-4.158; P = 0.537). Moreover, the 2-year aHRs of all-cause death, CD, re-MI, target lesion revascularization (TLR), target vessel revascularization (TVR), and non-TVR were similar.
Patients with AMI and prediabetes who received DP-DES or BP-DES during PCI showed comparable safety and efficacy during the 2-year follow-up period.
