Abstract:Objective To compare the effects of alirocumab and evolocumab separately combined with atorvastatin in the treatment of coronary heart disease complicated with hyperlipidemia.Methods Eighty-four patients with coronary heart disease and hyperlipidemia admitted to Ganzhou People's Hospital from January 2022 to June 2024 were selected as the research subjects. Using the odd/even number grouping method, they were divided into the control group (42 cases, treated with evolocumab and atorvastatin) and the observation group (42 cases, treated with alirocumab and atorvastatin). Blood lipids 〔triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C)〕, condition of carotid atherosclerosis 〔carotid plaque score (Crouse score) and intima-media thickness (IMT)〕 and the incidence of adverse reactions were compared between the two groups.Results After treatment, the levels of TC and LDL-C in observation group were lower than those in control group, and HDL-C level was higher than that in control group (P<0.05). There was no significant difference in TG between the groups after treatment (P>0.05). After treatment, the improvements in Crouse score and IMT were better in observation group than those in control group (P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups (P>0.05).Conclusion For patients with coronary heart disease and hyperlipidemia, alirocumab and evolocumab separately combined with atorvastatin both can effectively lower the levels of blood lipids and improve carotid atherosclerotic plaques, with good safety. Moreover, alirocumab is superior to evolocumab in improving blood lipids and carotid atherosclerotic plaque, which deserves clinical attention.
