Ticagrelor-Based Dual Antiplatelet Therapy Duration in CABG
China300 participantsStarted 2026-05-01
Plain-language summary
This randomized controlled trial aims to evaluate the impact of different durations of Ticagrelor-based dual antiplatelet therapy (DAPT) on saphenous vein graft (SVG) patency in patients undergoing coronary artery bypass grafting (CABG). A total of 300 patients will be randomly assigned to receive Ticagrelor (90 mg BID) + Aspirin (100 mg QD) for 3 months, 6 months, or 12 months, followed by aspirin monotherapy.The primary outcome is 1-year graft patency, assessed via coronary CT angiography. Secondary outcomes include bleeding events (BARC classification), major adverse cardiovascular and cerebrovascular events (MACCE), and all-cause mortality. The study aims to determine the optimal DAPT duration to balance graft patency benefits and bleeding risks, ultimately guiding postoperative antiplatelet strategies for CABG patients.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

. Patients with cardiogenic shock or hemodynamic instability.
. Patients with sick sinus syndrome, second- or third-degree atrioventricular block.
. Patients with contraindications for coronary computed tomography angiography (CCTA) or coronary angiography, including contrast media allergy.
. Patients requiring antiplatelet therapy other than aspirin or ticagrelor (e.g., clopidogrel, prasugrel) and unable to discontinue such medication after CABG, based on physician or investigator judgment.
. Patients on oral anticoagulants before CABG who must continue anticoagulation therapy postoperatively.
