Abstract:〔Abstract〕 Objective To analyze the clinical effect of Dengzhan Shengmai capsule combined with rosuvastatin calcium in the treatment of coronary heart disease complicated with hyperlipidemia. Methods Clinical data of 90 patients with coronary heart disease combined with hyperlipidemia admitted to the Third Affiliated Hospital of Sun Yat-Sen University-Yuedong from January 2021 to January 2023 were retrospectively selected, and the patients were divided into an observation group and a control group according to two different treatment schemes, with 45 cases in each group. Both groups received routine clinical intervention measures such as psychological intervention and dietary guidance. On the basis of this, the control group was treated with rosuvastatin calcium, and the observation group was additionally treated with Dengzhan Shengmai capsule orally. The treatment effect, occurrence of adverse reactions, blood lipid index and cardiac function index before and after treatment were compared between the two groups. Results The total effective rate of the observation group was higher than that of the control group, the difference was statistically significant (P < 0.05). After treatment, the levels of serum total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) in the observation group were lower than those in the control group, and the differences were statistically significant (P < 0.05). After treatment, left ventricular end-diastolic diameter (LVEDD) and left ventricular end-systolic diameter (LVESD) in the observation group were lower than those in the control group, and left ventricular ejection fraction (LVEF) was higher than that in the control group, with statistical significance (P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups (P > 0.05). Conclusion Dengzhan Shengmai capsule combined with rosuvastatin calcium has a high clinical effect on coronary heart disease complicated with hyperlipidemia, which can effectively improve the blood lipid level and cardiac function of patients, and has certain application value.
