A Nurse-Led Program to Improve Patient Health Promotion Behaviors Among Elderly Patients After PCI

The goal of this study is to develop and evaluate a nurse-led intervention program based on the Information-Motivation-Behavioral Skills (IMB) model to improve health-promoting behaviors and quality of life in elderly patients after percutaneous coronary intervention (PCI). It will also learn about the program's effects on self-efficacy and relevant objective clinical indicators. The main questions it aims to answer are: Does the IMB-based nurse-led intervention improve health-promoting behaviors in elderly PCI patients? What effects does the intervention have on patients' self-efficacy, quality of life, and objective clinical indicators? Researchers will compare the nurse-led IMB-based intervention to usual care to see if the program effectively enhances health-promoting behaviors and quality of life. Participants will: Receive the IMB-based nurse-led intervention or usual care Be followed up for a specified period with regular assessments Complete questionnaires on health-promoting behaviors, self-efficacy, and quality of life at baseline and at designated time points post-intervention Have objective clinical indicators measured and recorded
