Acute Myocardial Infarction (AMI) is a major disease that endangers people's health China. At present, clinical emphasis is given to "treatment" rather than "prevention", and a large number of AMI patients are hospitalized repeatedly without systematic and standardized health management after acute stage, falling into a vicious circle of "treatment without recovery". Nurse-led case management based on multidisciplinary collaboration is a new mode of disease management. In 1994, the United States took the lead in applying case management to the acute and chronic care system, providing comprehensive care services and promoting comprehensive recovery through multidisciplinary collaboration led by case managers. At present, the case management model of cardiovascular disease in Europe and the United States has been mature, but it is still in the exploratory stage in China. Through the establishment and application of nurse-led AMI case management program based on multidisciplinary collaboration, this study wants to establish a novel, standardized, and easy to popularize AMI whole-course prevention and control mode, providing theoretical and research basis for AMI disease management.

There are few domestic studies on cardiovascular disease case management in China, and the studies mainly aimed at the application of case management in out-of-hospital follow-up management. At present, there has been no reports on nurse-led the multidisciplinary whole course case management of AMI patients from admission to discharge, diagnosis and treatment, rehabilitation and secondary prevention. This study would apply case management to the whole course management of AMI patients from admission to 6 months after discharge. Pharmacists, nutritionists, rehabilitation specialists and psychiatrists coordinated by nurse would take the initiative to conduct individualized assessment and health guidance, and case managers would participate in the whole process of inpatient diagnosis and treatment. Coordinating multidisciplinary medical resources to jointly implement diagnosis and treatment and rehabilitation for patients can save medical costs and improve the quality of care.
