Abstract：Objective To evaluate the effects of cardiac rehabilitation training on cardiac function recovery and prognosis of patients with acute myocardial infarction after percutaneous coronary intervention(PCI)in cold areas of China.Methods A total of 1 914 patients diagnosed with acute ST-segment elevation myocardial infarction in the Department of Cardiology,Hegang People's Hospital,Heilongjiang Province from January 2016 to December 2023 were retrospectively enrolled in this study.All enrolled patients underwent primary coronary angiography and PCI.Patients were divided into rehabilitation training group(833 cases)and conventional treatment group(1 081 cases)according to whether they received cardiac rehabilitation training.The clinical data and in-hospital complications of the two groups were compared,and the results of cardiopulmonary exercise test after discharge of the rehabilitation training group were analyzed.The incidence of major adverse cardiovascular events(MACE)in 1 year of follow-up was compared between the two groups.Results The incidences of atrial and ventricular arrhythmia in the rehabili-tation training group was lower than those in the conventional treatment group(both P＜0.05).In the rehabilitation training group,patients were followed up at 1,3,6,and 12 months after discharge and underwent cardiopulmonary exercise testing.The results showed that the patients'power,heart rate,carbon dioxide output,oxygen intake,lung ventilation per minute,dead space ventilation ratio,end-tidal carbon dioxide partial pressure,carbohydrate metabolism percentage,cardiac output and stroke volume were significantly improvement compared to before(all P＜0.05).At 1-year follow-up,the incidence of MACE in the rehabilitation training group was significantly lower than that in the conventional treatment group[25.2％(210/833)vs 39.3％(425/1 081)](P＜0.001).Conclusion Cardiac rehabilitation training can effectively improve the recovery of cardiac function and prognosis of patients with acute myocardial infarction after PCI in cold areas of China.
