Abstract
BACKGROUND: Analyzing the clinical efficacy and mechanism of action of cardiac rehabilitation after revascularization for coronary multibranch lesions. METHODS: 150 patients with multiple coronary artery lesions were selected for the study from July 2022 to March 2023, and were randomly divided into observation group (75 cases, complete revascularization + cardiac rehabilitation intervention) and control group (75 cases, complete revascularization). The level of patients' 6 min walking experiment, quality of life, cardiac function indexes, and laboratory indexes were analyzed. RESULTS: The level of 6-min walking test was significantly higher in the observation group than in the control group (p<0.05); the quality of life of patients in the observation group was significantly higher than that of the control group (p<0.05); the levels of left ventricular end-systolic internal diameter (LVESD), left ventricular end-diastolic internal diameter (LVEDD), left ventricular pressure (LVP), and interventricular septal thickness (LVS) in patients in the observation group were significantly lower than that of the control group; and the level of LV ejection fraction (LVEFA) levels were significantly higher than those of the control group (P=0.00); serum homocysteine (Hcy) and blood uric acid (SUA) levels of patients in the observation group were significantly lower than those of the control group (P=0.00). CONCLUSION: Complete revascularization + cardiac rehabilitation intervention can effectively improve patients' 6-min walking test level, improve patients' cardiac function indexes, improve patients' quality of life, improve patients' laboratory index levels, and play a significant role in improving patients' prognosis, which is worthy of widespread promotion.
