Brief summary
The purpose of this study is to compare the efficacy and safety of ticagrelor with clopidogrel
Detailed description
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
Interventions
After 600mg loading dose, 75mg or 150mg Qd
90mg Bid

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| PRI | post operative 1 month | Platelet funtion were tested by flowcytometric vasodilator-stimulated phosphoprotein(VASP) analysis.And a platelet reactivity index (PRI) was calculated. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Major adverse cardiac events(MACEs) | follow-up for 1 month | cardiovascular death,angiographically confirmed stent thrombosis, recurrent acute coronary syndrome defined by the American College of Cardiology/American Heart Association guidelines,and recurrent revascularization by either coronary angioplasty or bypass surgery |
| major and minor bleeding | follow-up for 1 month | Major bleeding was defined as intracranial bleeding or clinically-overt bleeding associated with a decrease in hemoglobin of 50 g/L, according to the Thrombolysis inMyocardial Infarction (TIMI) criteria .Minor bleeding was also defined according to TIMI criteria . |
