The purpose of this study is to compare the efficacy and safety of ticagrelor with clopidogrel
180 elective percutaneous coronary intervention patients with clopidogrel resistance were randomized to three groups, Group 1:received clopidogrel 75mg qd ;Group 2:received clopidogrel 150mg qd ; Group 3:received ticagrelor 90mg bid after PCI.Platelet funtion were tested by flowcytometric vasodilator-stimulated phosphoprotein(VASP) analysis before PCI,and 3days,7days and 1 month after PCI,respectively.The aim of our study is to compare the efficacy and safety of ticagrelor with clopidogrel
