Abstract:

Objective To investigate the correlation between endothelial microparticles(EMP) and hyperlipidemia in elderly patients from Gulou Community in Nanjing. Methods Totally,100 elderly patients first diagnosed with hyperlipidemia at the Fourth Affiliated Hospital of Nanjing Medical University from Gulou Community in Nanjing from July 2020 to June 2021 were enrolled as hyperlipidemia group,while 100 healthy elderly subjects were enrolled as control group. The general data,blood routine test results [white blood cell(WBC) count,red blood cell(RBC) count,platelet(PLT) count,hemoglobin(Hb)],biochemical item determination results [triglyceride(TG),total cholesterol(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),alanine aminotransferase(ALT),aspartate aminotransferase(AST),blood urea nitrogen(BUN),serum creatinine(SCr),uric acid(UA),fasting blood glucose(FBG),high-sensitivity C-reactive protein(hs-CRP)],inflammatory factor determination results [interleukin(IL)-1β,tumor necrosis factor-alpha(TNF-α)] and EMP were collected. The independent risk factors of hyperlipidemia were analyzed by binary Logistic regression. Results Compared with control group,the levels of TC,TG,LDL-C,ALT,AST,hs-CRP,IL-1β,TNF-α and EMP in hyperlipidemia group were increased(P<0.01),and the levels of HDL-C were decreased(P<0.001). There was no statistical significance in BUN,SCr,UA and FBG between the 2 groups(P>0.05). Multivariate Logistic regression analysis showed that AST,hs-CRP,TNF-α,systolic blood pressure and EMP were independent risk factors for hyperlipidemic in elderly population [odds ratios(OR) were 1.089,1.528,1.048,1.065 and 1.946,95% confidence intervals(CI) were 1.031-1.150,1.197-1.951,1.024-1.072,1.026-1.106 and 1.166-3.248,P<0.05]. Conclusions EMP may be used as a biomarker of endothelial injury in elderly patients with hyperlipidemia.
