Abstract： Objective:To investigate the relationship between adipokines Apelin, adiponectin, Vaspin and susceptibility to coronary atherosclerotic heart disease (CHD) in the aged and their influence on the degree of coronary lesions.Methods:A total of 120 elderly patients with CHD admitted to Huozhou Coal and Power General Hospital from June 2022 to June 2023 were retrospectively selected(CHD group), and 120 elderly healthy physical examination subjects without CHD were selected as the control group in a 1:1 ratio. Baseline data, the levels of Apelin, adiponectin and Vaspin of the two groups were compared. Logistic regression was used to analyze the related factors of CHD susceptibility, and the levels of Apelin, adiponectin and Vaspin in patients with different CHD types, stenosis degree and number of lesions were compared. Spearman test was used to analyze the correlation between Apelin, adiponectin and Vaspin with stenosis degree and number of lesions.Results:The levels of Apelin, adiponectin and Vaspin in the CHD group were lower than those in the control group: (70.02 ± 13.54) ng/L vs. (86.75 ± 7.40) ng/L, (2.03 ± 0.67) μg/L vs. (2.80 ± 0.29) μg/L, (1.02 ± 0.31) μg/L vs. (2.10 ± 0.28) μg/L, there were statistical differences ( P<0.05). The Logistic regression equation was as follows: Logit ( P) = 2.953+1.401 × triglyceride + 1.446× low-density lipoprotein -0.761× Apelin -0.892 × adiponectin - 0.847 ×Vaspin, each coefficient had statistical significance ( P<0.05), it was suggested that with the increase of triglyceride and low-density lipoprotein levels and the decrease of Apelin, adiponectin and Vaspin levels, the susceptibility to CHD was gradually increased ( P<0.05). The levels of Apelin, adiponectin and Vaspin in patients with stable angina pectoris, unstable angina pectoris and acute myocardial infarction were decreased successively ( P<0.05). The levels of Apelin, adiponectin and Vaspin in patients with mild, moderate and severe stenosis were decreased successively ( P<0.05). The levels of Apelin, adiponectin and Vaspin in patients with single, double, 3 or more branches were decreased successively ( P<0.05). The results of Spearman test showed that Apelin, adiponectin and Vaspin were negatively correlated with the degree of stenosis ( r = - 0.728, - 0.808, - 0.779, P<0.05) and the number of lesions ( r = - 0.686, - 0.773, - 0.717, P<0.05). Conclusions:Apelin, adiponectin, and Vaspin are associated with the susceptibility of elderly people to CHD, and all three are negatively correlated with the severity of CHD stenosis and the number of diseased vessels. They are expected to become biomarkers for the onset and severity of CHD, providing a target idea for the prevention and treatment of CHD.
