Application of early multi-dimensional cardiac rehabilitation training in elderly patients with acute myocardial infarction and hypertension undergoing PCI
Objective:To explore application of early multi-dimensional cardiac rehabilitation training in elderly pa-tients with acute myocardial infarction(AMI)and hypertension undergoing percutaneous coronary intervention(PCI).Methods:A total of 120 elderly AMI patients with hypertension who received PCI in First Affiliated Hospital of Harbin Medical University between May 2019 and February 2021 were selected and divided into control group(n=60,from May 2019 to April 2020)and observation group(n=60,from May 2020 to February 2021)according to order of visit time.Control group received routine postoperative rehabilitation intervention,while observation group received additional early multi-dimensional cardiac rehabilitation training.Both groups were continuously inter-vened until 3 months after PCI.Cardiac function,cardiopulmonary exercise test related indexes,scores of somatic self-rating scale(SSS)and medical outcomes study 36-item short-form heath survey(SF-36)before and after intervention,incidence rates of major adverse cardiovascular events(MACE),rehospitalization and patients'satis-faction after 6-month follow-up were compared between two groups.Results:Compared with the control group on 3 months after PCI,patients in observation group had significant higher left ventricular ejection fraction(LVEF)[(55.78±8.67)％vs.(59.57±9.66)％],6min walking distance(6MWD)[(581.25±35.33)m vs.(641.17±19.80)m],anaerobic threshold(AT)[(15.47±3.64)ml·kg-1·min-1 vs.(27.87±2.99)ml·kg-1·min-1]and SF-36 score[(64.72±3.14)points vs.(69.48±3.80)points],and significant lower ventilation equivalent of carbon dioxide slope(VE/VCO2)[(29.70±2.55)vs.(23.78±1.71)]and SSS score[(33.72±1.72)points vs.(30.50±1.53)points](P＜0.05 or＜0.01).Compared with control group after 6-month follow-up,patients in observation group had significant lower total incidence rate of MACE(21.67％vs.8.33％)and rehospitalization rate(20.00％vs.6.67％),and significant higher patients'satisfaction(83.33％vs.96.67％)(P＜0.05 all).Con-clusion:The application of early multi-dimensional cardiac rehabilitation training in elderly patients with acute my-ocardial infarction and hypertension undergoing PCI can improve the cardiac function and somatization symptoms with good short-term prognosis,which is easy to be accepted and approved by patients.
