Retrospective cohort study of Korean National Healthcare Insurance Database. To investigate clinical outcomes of bare metal stents versus drug eluting stents in patients who underwent periprocedural red blood cell transfusion.
A Korean nationwide, multi-center, retrospective observational cohort study. The receipt of red blood cell transfusion is at high risk of cardiac events or death. But little is know regarding the comparative outcomes of BMS and DES implantation in patients who underwent periprocedural red blood cell transfusion. Longitudinal data is collected from administrative claims in the national health insurance services of Korea. All Korean data(N=500,591) undergoing PCI from 2006 to 2015 is extracted. BMS or DES Patients(N=28,322) who received periprocedural red blood cell transfusion is investigate. Clinical outcomes until December 31, 2017 is investigate. Primary endpoint is a time to the first major adverse clinical event(MACE) defined as a composite of all-cause death, revascularization, critically ill cardiovascular status, or stroke.
