Background
The polymer-free biolimus-A9 drug-coated stent (DCS) was reported to have superior safety and efficacy outcomes compared with a bare metal stent in the LEADERS FREE trial of high-bleeding-risk patients with acute coronary syndrome and on dual antiplatelet treatment (DAPT) for 1 month. The aim of this investigation was to evaluate the DCS in a consecutive cohort of patients with ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PPCI).
Methods
We analyzed data from 164 consecutive STEMI patients who underwent PPCI using the DCS at our institution. The primary efficacy endpoint was clinically indicated target lesion revascularization (ciTLR); the primary safety endpoint was a composite of cardiac death, myocardial infarction, and definite/probable stent thrombosis. Clinical outcomes at 1 year are presented here.
Results
The mean age of the patients was 61.5 ± 15.5 years, and 86.6% were male. The median symptom-to-balloon-time was 55 min. In 57.9% of patients (n = 95), the infarct had an anterior location. PPCI achieved Thrombolysis in Myocardial Infarction (TIMI) grade 3 flow in 163 of 164 patients (99.4%). All patients were prescribed DAPT for 1 year. At 1 year, ciTLR occurred in 1.2% of patients, the primary safety endpoint was reached in 4.3% of patients, and definite stent thrombosis was noted in 0.6% of patients.
Conclusion
In this consecutive real-world cohort of patients, the DCS was safe and efficacious when used for PPCI in patients with STEMI.
