Efficacy of Buqi Huoxue Decoction Combined with Cardiac Rehabilitation Nursing after Coronary Intervention in Patients with Acute ST-Segment Elevation Myocardial Infarction and Its Influence on Prognosis

Objective. To investigate the efficacy of the application of Buqi Huoxue Decoction combined with cardiac rehabilitation nursing for patients with acute ST-segment elevation myocardial infarction (STEMI) after percutaneous coronary intervention (PCI) and its influence on the prognosis. Methods. 120 STEMI patients undergoing PCI were randomly divided into control group, cardiac care group, traditional Chinese medicine and western medicine group (TCM + WM group), and comprehensive treatment group. The control group was treated with a conventional antiplatelet therapy. On the basis of the control group, the cardiac care group was combined with cardiac care treatment. The TCM + WM group was combined with Buqi Huoxue Decoction, and the comprehensive treatment group was combined with cardiac rehabilitation care and Buqi Huoxue Decoction. The total clinical effective rate, readmission rate, and adverse reaction rate of the four groups were measured. Moreover, the myocardial injury markers (creatine kinase isoenzyme (CK-MB), cardiac troponin I (cTnI), and α-Hydroxybutyrate dehydrogenase (α-HBDH)), vascular endothelial function indexes (endothelin (ET-1) and vascular endothelial growth factor (VEGF)), cardiac function indexes (left ventricular ejection fraction (LVEF), left ventricle shortening rate (LFS), left ventricular end diastolic diameter (LVEDd), and left ventricular end systolic diameter (LVESd)), and QOL quality of life score (appetite, spirit, sleep, fatigue, and daily life) were measured. Results. The total effective rate of comprehensive treatment group was obviously increased versus to the control group and cardiac care group. The CK-MB, cTnI, α-HBDH, ET-1, LVEDd, and LVESd levels and SAS and SDS scores in the four groups were decreased, and VEGF, LVEF, and FS levels and QOL quality of life scores were increased after treatment. Moreover, the comprehensive treatment group has more significant changes than the other three groups. The readmission rate in comprehensive treatment group was significantly lower than the other three groups, and the difference in the incidence of adverse reactions in the four groups was not statistically significant. Conclusion. Buqi Huoxue Decoction combined with cardiac rehabilitation after PCI has a significant clinical effect on STEMI patients with PCI postoperative treatment, which can effectively reduce myocardial injury, improve the patient's cardiac function and vascular endothelial function, and improve the patient's
