About

The main purpose of our study is to investigate whether haemodialysis itself affects the efficacy of antiplatelet drugs and the effects of two different types of dialysis membranes (polysulfone membranes and polyamide membranes) on antiplatelet efficacy. A total of 60 patients with ESRD and under dual-antiplatelet treatmen for at least 5 days will be enrolled and divided into the Clopidogrel group (clopidogrel 75mg qd;aspirin 100mg qd, n=30) and the Ticagrelor group (ticagrelor 90mg bid; aspirin 100mg qd, n=30). All included patients will receive haemodialysis by two different types of dialysis membrane.Platelet aggregation of venous blood from all patients will be detected by LTA and VerifyNow immediately before and after two times of haemodialysis.

Enrollment: 60 estimated patients

Sex: All
