Effect of Early Rehabilitation Nursing on Patients with Myocardial Infarction: A Meta-analysis

Objectives: In this study, we systematically evaluated the effectiveness and safety of rehabilitation nursing in the treatment of patients with acute myocardial infarction (AMI), and its effect on improving the cardiac function and exercise tolerance of AMI patients. Methods: All relevant published articles were searched through a computer-based retrieval of PubMed, Embase, Biosis Previews, Cochrane Library, Web of Science, China National Knowledge Internet, China Biomedical Literature Service System, Weipu Information Chinese Periodical Service Platform and Wanfang databases since their establishment. Randomized controlled trials on rehabilitation nursing and exercise intervention for patients with AMI were included, and the Cochrane risk-of-bias tool was used for quality evaluation. After quality evaluation and data extraction, we conducted statistical analysis using RevMan 5.3. Results: A total of 15 English articles were included. The meta-analysis showed that the left ventricular ejection fraction (mean difference [MD] = 5.76, 95% confidence interval [CI]: 4.55-6.97, p < .00001), left ventricular end-diastolic diameter (MD = -6.81, 95% CI: -8.17--5.45, p < .00001) and 6-minute walking distance (MD = -2.41, 95% CI: -3.42--1.40, p < .00001) showed statistically significant differences between the rehabilitation nursing group and the control group (p < .0001). However, no statistically significant difference was found in systolic blood pressure (MD = 2.29, 95% CI: -2.53-7.12, p = 0.35). Conclusion: Early rehabilitation nursing can effectively improve cardiac function and exercise tolerance in patients with AMI. It has a degree of guiding significance for improving the quality of life of patients with MI and reducing complications.
