Abstract:

Objective To investigate the relationship between plasma galectin 3(Gal3) and low-density lipoprotein cholesterol(LDL-C) stratified by ages in patients with cardiovascular disease(CVD). Methods From January 2018 to August 2020,257 inpatients in the Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were enrolled. These patients were classified into 4 groups,34-54-year-old group(58 cases),55-64-year-old group(64 cases),65-74-year-old group(67 cases) and 75-94-year-old group(68 cases). Basic data,including sex,age,drug usage,smoking history and underlying diseases,were collected. White blood cell(WBC) count,hemoglobin(Hb),N-terminal pro-B-type natriuretic peptide(NT-proBNP),glycated hemoglobin A1c(HbA1c),total cholesterol(TC),triglyceride(TG),LDL-C and high-density lipoprotein cholesterol(HDL-C) were determined,and plasma Gal3 was determined as well. All the patients were stratified in the risk of CVD and were classified into LDL-C abnormal group(156 cases) and LDL-C normal group(101 cases). According to whether patients had heart failure,they were classified into heart failure group(63 cases) and control group(189 cases). Spearman correlation analysis was used to assess the correlation between the indicators. Logistic regression analysis was used to evaluate the predictors of LDL-C abnormalities. Results Among the 4 age groups,the proportions of heart failure, ACEI or ARB usage and β receptor inhibitor usage and NT-proBNP,Hb,TC,TG and LDL-C levels had statistical significance(P<0.05),and the other indicators had no statistical significance(P>0.05). The results of Spearman correlation analysis showed that Gal3,TC,TG and LDL-C were negatively related to age in patients with CVD(P<0.05),and age had no correlation with HDL-C(P=0.551). There was a positive correlation between Gal3 and LDL-C in 55-64-year-old and 65-74-year-old groups(P<0.001). In CVD patients who were not taken lipid-lowering drugs,Gal3 was positively correlated with LDL-C(P<0.001). Logistic regression analysis showed that the increased Gal3 level and the history of hypertension were independent predictors for LDL-C abnormalities in 65-74-year-old group [odds ratios(OR) were 1.977 and 4.480,95% confidence intervals(CI) were 1.157-3.379 and 1.335-15.032,respectively]. Age and Gal3 levels in heart failure group were higher than those in control group(P<0.05),and LDL-C levels were lower than those in control group(P<0.05). In both heart failure and control groups,Gal3 was positively correlated with LDL-C(r=0.307 and 0.298,P<0.05). Conclusions In patients with CVD,the correlation between Gal3 and LDL-C levels is age-related. In 65-74-year-old CVD patients,Gal3 is an independent predictor for LDL-C abnormalities.
