Thrombosis formation is the core mechanism for the occurrence of major adverse cardiovascular and cerebrovascular events in patients with coronary heart disease. Antithrombotic therapy is one of the most important treatment methods for secondary prevention of coronary heart disease. Antithrombotic drugs, while reducing ischemic events, often significantly increase the risk of bleeding. How to balance the risk of recurrent ischemic events and bleeding events in patients with coronary heart disease is a major challenge in the treatment of coronary heart disease. This project establishes a high-quality multicenter, prospective coronary heart disease cohort, with patients covering various clinical characteristics such as different regions, ages, and comorbidities. It verifies the ischemic risk and bleeding risk model developed in Project 1, compares the efficacy improvement of the new model with the traditional risk model, and verifies the effectiveness and stability of the model in different subgroups of the population, and assesses the generalizability of the model in real-world clinical practice, providing high-quality evidence-based basis for the formulation of individualized and precise antithrombotic strategies for coronary heart disease.
