Clinical Application of Cardiac Rehabilitation Program Based on Self-efficacy Theory in Patients with Acute Myocardial Infarction Undergoing Percutaneous Transluminal Coronary Intervention

Objective: This study aimed to evaluate the effectiveness of a cardiac rehabilitation program based on self-efficacy theory in patients with acute myocardial infarction (AMI) undergoing percutaneous transluminal coronary intervention (PCI). Methods: A retrospective analysis was conducted on the medical records of 417 patients with AMI who underwent PCI at our hospital from May 2020 to May 2022. Patients were categorized into a control group (210 patients following a cardiac rehabilitation program) and an observation group (207 patients following a cardiac rehabilitation scheme based on self-efficacy theory). Data on demographics, diseases, and 1-year follow-up information were collected from the participants. Comparisons between the groups were made in terms of left ventricular ejection fraction (LVEF), six-minute walk distance test (6MWD), hospitalization duration, the 36-item short-form health survey (SF-36) score, and the incidence of angina pectoris and AMI recurrence within one-year post-management. Results: Initially, the groups had no significant difference in LVEF and 6MWD (p > 0.05). However, after 1 and 3 months of management, the observation group exhibited higher LVEF and 6MWD than the control group (p < 0.001). The observation group had a significantly shorter hospitalization duration (p < 0.001) and higher SF-36 scores post-management (p < 0.001). Furthermore, the incidence of angina pectoris and AMI recurrence within a year post-management was lower in the observation group (p < 0.05). Conclusion: The cardiac rehabilitation program grounded in self-efficacy theory significantly improves cardiac function in patients with AMI, accelerates their post-PCI rehabilitation, improves quality of life, and reduces the recurrence of angina pectoris and AMI. This approach offers new directions for cardiac rehabilitation management of AMI.
