Effects of the hospital-community-family trinity cardiac rehabilitation on patients with acute myocardial infarction after percutaneous coronary intervention: A randomized trial.

OBJECTIVES: This study aimed to develop a hospital-community-family trinity cardiac rehabilitation (CR) intervention program and assess its' effects on patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI). METHODS: Between April 2022 and April 2023, patients who had experienced AMI after PCI were enrolled. These patients were randomly assigned to an intervention group (IG) or a control group (CG) in equal numbers. The CG received standard CR, while the IG participated in the advanced trinity CR program in addition to the standard CR. Key parameters measured included the anaerobic threshold (AT), maximum oxygen uptake (V̇O2max), maximum exercise load (MEL), metabolic equivalent (MET), left ventricular ejection fraction (LVEF), left ventricular end-systolic volume (LVESV), left ventricular end-diastolic volume (LVEDV), and quality of life (measured by the SF-36). These were assessed pre-intervention and at 3, 6, 9, and 12 months post-intervention. SPSS.26 was employed for data analysis, with statistical methods such as repeated measures analysis of variance (ANOVA), Chi-square tests, and independent sample t-tests. RESULTS: A total of 110 patients completed the intervention, 55 in each group. There was no significant difference in the scores of all indicators between the two groups before intervention (P > 0.05). However, at 3, 6, 9 and 12 months after intervention, the scores of AT, VO2max, MEL, MET, LVEDV, LVESV, LVEF, and quality of life in the intervention group were higher than those in the control group, there was statistical significance at four-time points, group, time, and interaction effect (P < 0.05). CONCLUSIONS: The hospital-community-family trinity CR intervention program developted in this study significantly improved exercise endurance, cardiac function, and quality of life in patients with AMI after PCI.
