Optimal Antiplatelet Therapy for Chinese Patients With Coronary Artery Disease (OPT-CAD)

Antiplatelet therapy is the cornerstone for the prevention of atherothrombosis in patients with coronary artery disease (CAD). However, the efficacy and safety of antiplatelet therapy are varied due to ethnic and/or individual variability. The aim of the OPT-CAD study was to demonstrate contemporary status and outcomes of antiplatelet therapy in Chinese CAD patients, and to explore predictors of ischemic or bleeding events in such cohort.Patients above 18 years old who were diagnosed as CAD and received antiplatelet therapy were prospectively enrolled in this national wide, non-intervention registry. All medications and laboratory tests were physician discretion.
