A Study on the Development and Application of a Cardiac Rehabilitation Nursing Intervention Protocol for Patients With First-Episode Acute Myocardial Infarction Following PCI, Based on a Socio-Ecological Theory Model

The purpose of this \[Study Type: Clinical Trial\] is to investigate whether a cardiac rehabilitation nursing intervention based on the socio-ecological model can improve rehabilitation-related outcomes in patients. The study population consists of \[adult patients with acute myocardial infarction who have undergone percutaneous coronary intervention (PCI)\]. The primary research questions addressed in this study are: 1. Can a social-ecological model-based cardiac rehabilitation intervention improve adherence to cardiac rehabilitation among patients with myocardial infarction following PCI?\] 2. Can a social-ecological model-based cardiac rehabilitation intervention improve cardiac function and quality of life among patients with myocardial infarction following PCI?\] The researchers will compare the \[intervention group and the control group\] to observe whether there are \[group differences in cardiac rehabilitation adherence, cardiac function, and quality of life levels\]. Intervention group: Receives routine cardiology care combined with a social-ecological model-based cardiac rehabilitation intervention (1. In-hospital guidance; 2. Multidimensional, continuous rehabilitation support at home and in the community; 3. Regular follow-up assessments, etc.); Control Group: Received routine care from the cardiology department and standard discharge cardiac rehabilitation education; All participants completed questionnaire surveys and had cardiac function-related indicators collected at baseline, 3 months into the intervention, and 6 months into the intervention.

Inclusion Criteria: * Patients with a first-time diagnosis of acute myocardial infarction who underwent PCI for the first time; * Age ≥ 18 years; * Alert and able to communicate effectively; ④ Willing to participate and sign an informed consent form. Exclusion Criteria: * Presence of absolute contraindications to exercise (e.g., unstable angina, severe heart failure, malignant arrhythmias, etc.); * Concurrent severe comorbidities (e.g., end-stage renal disease, malignant tumors, severe cognitive impairment); * Participation in other rehabilitation clinical trials.
