ISAR-TEST-4. Cardiac death, MI, or TLR at 12 months: 13.8% of the biodegradable polymer group vs. 14.4% of the permanent polymer group Cardiac death: 2.8% vs. 3.2% (p = 0.5) ARC definite/probable stent thrombosis: 1.0% vs. 1.5% (p = 0.29).

ISAR-TEST-4 Cardiac death, MI, or TLR at 12 months: 13.8% of the biodegradable polymer group vs. 14.4% of the permanent polymer group Cardiac death: 2.8% vs. 3.2% (p = 0.5) ARC definite/probable stent thrombosis: 1.0% vs. 1.5% (p = 0.29) Trial design: Patients with stable coronary disease or ACS were randomized to the biodegradable polymer DES (rapamycin-eluting; n = 1,299) vs. permanent polymer DES (sirolimus-eluting, n = 652 or everolimus-eluting, n = 652). Mean follow-up was 1 year. Results (p for non-inferiority = 0.005) (p = NS) % Conclusions • Among patients with either stable coronary disease or ACS undergoing stent implantation, a biodegradable polymer DES was non-inferior to a permanent polymer-based DES • Biodegradable polymer DES associated with similar frequency of the composite endpoint of cardiac death, MI, or TLR at 12 months Cardiac death, MI, or TLR at 12 months Cardiac death Biodegradable polymer group Permanent polymer group Byrne RA, et al.
