Summary

This study follows 500 heart bypass patients for 10 years to see if taking two blood thinners (ticagrelor plus aspirin) for one year after surgery reduces the risk of heart attacks, strokes, or death compared to taking just one. Participants will be contacted by phone to report their health and any heart events. The goal is to learn whether short-term dual therapy provides lasting benefits.

Who can take part

Who is studied

All 500 patients who were enrolled and randomized in the DACAB trial (NCT02201771) between July 2014 and November 2015. These patients underwent elective isolated coronary artery bypass grafting (CABG) with saphenous vein grafting at six tertiary hospitals in China. For this 10-year extended follow-up study, all original DACAB participants are eligible, regardless of their vital status or medication use during the follow-up period. Information on deceased participants will be collected from medical records, family members, or the national China Centre for Disease Control database to minimize loss to follow-up bias.
