Introduction:
This pooled analysis was conducted to assess the clinical safety and performance of the Supra family (Sahajanand Medical Technologies Ltd., Surat, India) of sirolimus-eluting stents (SES) in patients with acute coronary syndromes (ACSs) including ST-segment elevation myocardial infarction (STEMI) from two real-world all-comers Indian registries at 1 year.
Methods:
We evaluated 1,824 patients with ACS who underwent percutaneous coronary intervention with the Supra family of SES from two real-world Indian registries (891 patients from T-Flex registry and 933 patients from Tetriflex real-world registry). The primary endpoint was the incidence of target lesion failure (TLF) defined as a composite of cardiac death, target-vessel myocardial infarction (TV-MI), and target lesion revascularization (TLR) at 1-year follow-up. The safety endpoint was stent thrombosis at 1-year follow-up.
Results:
Among a total of 1,824 patients with ACS, 689 (37.8%) patients presented with STEMI. In ACS and STEMI groups, 47.6% and 41.8% patients had multivessel disease, respectively. Of 2,128 lesions in ACS group, 76.7% lesions were type B2/C and 16.2% lesions were totally occluded. In the STEMI group, out of 784 treated lesions, 76.7% were type B2/C lesions and 21.9% were totally occluded. At 1-year follow-up, incidence of TLF was 5.3% (cardiac death: 0.9%, TV-MI: 2.5%, TLR: 1.9%) in patients with ACS and 6.2% (cardiac death: 1.4%, TV-MI: 2.1%, TLR: 2.7%) in patients with STEMI. The 1-year rate of definite/probable stent thrombosis was 0.3% and 0.7% in patients with ACS and STEMI, respectively.
Conclusion:
This patient-level pooled analysis provides evidence for the safe and effective use of the Supra family of SES in complex patient populations such as ACS and even in STEMI with favorable rates of TLF and stent thrombosis at 1-year follow-up.
