Use of endothelial progenitor cell capture stent (Genous Bio-Engineered R Stent) during primary percutaneous coronary intervention in acute myocardial infarction: Intermediate- to long-term clinical follow-up

Aims We assessed the use of the endothelial progenitor cell (EPC) capture stent in primary percutaneous intervention in ST-elevation myocardial infarction (STEMI). Methods and Results One hundred and twenty patients with acute STEMI without cardiogenic shock received 129 EPC capture stents. Procedural success was achieved in 95% of patients. Dual anti platelet therapy was given for a month and statin therapy started immediately after the procedure. The study end points are major adverse cardiac events inhospital and at 30 days, 6 months, and 1 year. Hypertension was present in 47.5% and diabetes mellitus in 30% of the patients. The left anterior descending artery was the treated artery in 54% of the patients. Mean lesion length was 17.4 +/- 7.15 mm with mean reference vessel diameter of 3.18 +/- 0.6 mm. Platelet glycoprotein IIb/IIIa inhibitor was used in 14% of patients and 58% had thrombosuction before stent implantation. Ninety-five percent of patients achieved Thrombolysis in Myocardial Infarction 3 flow with cumulative major adverse cardiac event rate at 1.6% inhospital, 4.2% at 30 days, 5.8% at 6 months, and 9.2% at 1 year. There was 1 patient each with acute and subacute stent thrombosis but no incidence of late stent thrombosis. Conclusion Using EPC capture stent during primary percutaneous coronary intervention for STEMI is feasible and safe.
