Coronary artery disease (CAD) is a major chronic condition severely impacting population health in China. Our previous cohort studies revealed a high comorbidity rate between CAD and frailty, suggesting their interrelated equivalence as clinical syndromes with shared risk factors. In recent years, pilot integrated health management initiatives in China have demonstrated promising outcomes, yet evidence remains scarce regarding patients with concurrent CAD and frailty-a critical gap needing urgent resolution to achieve the "Healthy China 2030" strategic goals.

Building on prior research, this project aims to systematically evaluate existing management models for patients with CAD and frailty, develop a tailored health management framework, and implement it in clinical settings through empirical studies. The model will be optimized according to regional and demographic variations, leveraging cardiac rehabilitation centers, exercise-based interventions, and internet-enabled technologies to enhance coordinated care. By improving exercise efficacy, mitigating frailty progression, and enhancing quality of life, this initiative seeks to establish a robust chronic disease management system. The findings will provide evidence for formulating regional health policy and insurance strategies in Anhui Province, ultimately improving standardized management rates for chronic diseases.
