Objective To investigate the clinical efficacy of a cardiac rehabilitation nursing model in patients with acute myocardial infarction (AMI), and to analyze its effects on recovery progression and quality of life, thereby providing practical references for clinical nursing practice. Methods A total of 110 AMI patients admitted to the Department of Cardiology at our hospital between March 2024 and December 2025 were enrolled and randomly assigned into either a control group or an observation group using a random number table, with 55 patients in each group. The control group received conventional cardiovascular nursing care, while the observation group received a systematic cardiac rehabilitation nursing intervention in addition to the standard care. The intervention lasted for three months. Post-intervention outcomes were compared between the two groups, including cardiac function indicators left ventricular ejection fraction (LVEF) and 6-minute walk distance, incidence of complications, length of hospital stay, and quality-of-life scores assessed by the SF-36 questionnaire. Results After intervention, the left ventricular ejection fraction (LVEF) of the observation group was (57.2±4.5)%, which was significantly higher than (50.5±5.3)% of the control group (P<0.05). The 6-minute walking distance of the observation group was (482.3±33.1) m, obviously longer than (415.6±39.2) m of the control group (P<0.05). The complication incidence rate of the observation group was 5.45% (3/55), remarkably lower than 18.18% (10/55) of the control group (P<0.05). The hospital stay of the observation group was (10.2±2.1) days, shorter than (14.5±2.8) days of the control group (P<0.05). In terms of quality of life, the scores of all dimensions of the SF-36 scale including physical function, mental state, social interaction and bodily pain in the observation group were significantly higher than those in the control group (P<0.05). Conclusion Implementing a cardiac rehabilitation nursing model in patients with acute myocardial infarction effectively improves cardiac function, enhances exercise tolerance, reduces complication rates, shortens hospitalization duration, and significantly elevates quality of life. This approach holds substantial clinical value and warrants broader application.
