Objective: To explore the effect of in-hospital phase I cardiac rehabilitation exercises on the cardiopulmonary function and prognosis of patients with acute myocardial infarction after percutaneous coronary intervention (PCI). Methods: A total of 84 patients with acute myocardial infarction (AMI) who underwent PCI in the Department of Cardiology, Songjiang District Central Hospital from September 2019 to September 2020 were selected as the research objects. They were divided into the control group and the rehabilitation group by random drawing, with 42 cases in each group. The control group received conventional treatment and nursing care, and the rehabilitation group performed phase I cardiac rehabilitation gymnastics treatment on the basis of the control group. The resting heart rate, resting systolic blood pressure, resting diastolic blood pressure and finger end oxygen indexes of the two groups were recorded before and after in-hospital rehabilitation training, the cardiac function of the two groups was compared using echocardiography, 6-min walk test, cardiopulmonary exercise test, and brief health questionnaire (SF-36) indicators, cardiopulmonary function and quality of life indicators. The MACE event was followed up within 1 year after discharge. Results:After treatment, the left verdricular ejection fraction(LVEF) of the two groups was improved as compared with that before treatment (P<0.05), and the improvement of the rehabilitation group was more significant than that in the control group. After in-hospital rehabilitation, the resting heart rate and resting systolic blood pressure in the rehabilitation group were lower than those in the control group (P<0.05). At 6th month after operation, the LVEF in the two groups was improved as compared with that before treatment (P<0.05), and the improvement in the rehabilitation group was more significant than that in the control group. Before discharge and at 6th month after operation, the 6-min walking distance in the rehabilitation group was significantly longer than that in the control group, and the difference was statistically significant (P<0.01). At 6th month aft-er the operation, the peak VO2, peakMETs, AT, and O2 pulse in the rehabilitation group were higher than those in the control group, and the difference was statistically significant (P<0.05). After treatment, the scores of the SF-36 dimensions in the two groups were higher than those before treatment, and those in the re-habilitation group were significantly higher than in the control group (P<0.05). The 1-year follow-up results showed that the incidence of MACE events in the rehabilitation group was lower than that in the control group, but there was no significant difference. Conclusion: In-hospital phase I cardiac rehabilitation gymnastics can improve the cardiopulmonary function of patients with acute myocardial infarction after PCI, effectively improve the patient’s exercise endurance and quality of life, and is safe and feasible. |
