RESUMO
BACKGROUND: The aim of this study was to assess the effects of rehabilitation management on the lifestyle and quality of life of patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI) based on the behavior change theory. METHODS: A total of 222 CHD patients admitted from January 2019 to April 2021 were randomly divided into research and control groups (N.=111). Control group was administered with routine postoperative nursing management, while research group received behavior changing nursing intervention. The quality-of-life scores, blood pressure and blood lipid levels before and after surgery, as well as length of hospitalization, treatment duration, symptom relief time, incidence rate of complications and nursing satisfaction were compared. RESULTS: After surgery, the length of hospitalization, treatment duration and symptom relief time were shorter, and the incidence rate of complications, levels of total cholesterol (TC), triglycerides (TG) and low-density lipoprotein cholesterol (LDL-C), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were lower in research group than those in control group, while research group was better in physical function, social function, physiological functioning, physical pain, mental health, emotional functioning, vitality and overall health scores, satisfaction and high-density lipoprotein cholesterol (HDL-C) level than control group (P<0.05). CONCLUSIONS: The application of behavior change theory in the cardiac rehabilitation management of patients with CHD after PCI can improve the lifestyle and quality of life.
