Summary

This study is designed to test the hypothesis that the onset of the antiplatelet effect 90mg-first-dose of ticagrelor will be more rapid and greater than 300mg-loading-dose of clopidogrel evaluated by P2Y12 reaction units measured by Verify NowTM P2Y12 assay at 1 hour in patients undergoing one-stop Hybrid coronary revascularization(HCR).

Detailed description

This is a single-center, randomized, active-controlled, open-label, prospective study, and the study is designed to test the hypothesis that the onset of the antiplatelet effect 90mg-first-dose of ticagrelor will be more rapid and greater than 300mg-loading-dose of clopidogrel evaluated by P2Y12 reaction units (PRU) measured by Verify NowTM P2Y12 assay at 1 hour in patients undergoing one-stop HCR. The first dose of study drug (ticagrelor 90mg or clopidogrel 300 mg) will be administered as powder via a nasogastric tube after confirmation of left internal mammal artery to left anterior descending coronary antery (LIMA-LAD) graft patency during the HCR procedure. Approximately 60 patients will enrol for the study. Patients will be randomized equally (ratio 1:1) to the two treatment arms of this study. The anticipated duration of the study is approximately 15 months, including an anticipated enrolment period of 12 months and follow-up period of 3months.

Interventions

Type	Name	Description
DRUG	Ticagrelor	Patients will receive first dose of 90mg ticagrelor tablets (powdered) taken via nasogastric tube after LIMA-LAD bypass establishing, the close of thorax and before PCI procedure, followed by 90mg of ticagrelor 12 hours after the first dose. The third dose of ticagrelor will be given to patients after the 24 hour blood sample has been obtained and 24 hours after the first dose. Thereafter, the patients will take 90mg of ticagrelor orally bid, at approximately 12-hourly intervals. The total study period is 3 months.
DRUG	Clopidogrel	Patients will receive a loading dose of 300mg clopidogrel tablets (four 75mg capsules powdered) taken via nasogastric tube after LIMA-LAD bypass establishing, the close of thorax and before PCI procedure. The second dose of clopidogrel will be given to patients after the 24 hour blood sample has been obtained and 24 hours after the first dose. Thereafter, the patients will take 75mg of clopidogrel capsules orally od. The total study period is 3 months.
