NCT02163954

Brief Summary

Patients with severe chronic kidney disease or end stage renal disease (ESRD) on hemodialysis (HD) exhibited higher platelet reactivity to clopidogrel than did those with normal renal function. Not enough study has been conducted about the antiplatelet effects of ticagrelor in these cardiovascular high risk patients. We hypothesized ticagrelor would achieve more and faster antiplatelet effects compared with clopidogrel in ESRD patients on HD.
