Abstract:
Objective To explore the association between cognitive function and non-traditional blood lipid parameters in patients with cerebral small vessel disease （CSVD）. Methods A prospective study was conducted among 376 CSVD patients who were treated in Dongfang Hospital，Beijing University of Chinese Medicine，from July 2017 to August 2022. Blood samples were collected from all subjects in the morning after 12 hours of fasting to measure blood lipid parameters，and then non-traditional blood lipid parameters were calculated. According to the Montreal Cognitive Assessment Scale，the patients were divided into cognitive impairment CSVD group and non-cognitive impairment CSVD group. A multivariate logistic regression analysis was used to investigate the association between non-traditional blood lipid parameters and cognitive function in CSVD patients，and the receiver operating characteristic （ROC） curve was used to assess their predictive value. Results A total of 376 CSVD patients were enrolled，among whom there were 250 patients with cognitive impairment and 126 patients without cognitive impairment. The multivariate logistic regression analysis showed that TC/HDL-C （OR=1.454，95%CI 1.147-1.843，P=0.002） and LDL-C/HDL-C ratio （OR=1.457，95% CI 1.109-1.915，P=0.023） were independently associated with cognitive impairment in CSVD patients. The ROC curve analysis showed that TC/HDL-C ratio had an area under the ROC curve （AUC） of 0.606 （95%CI 0.547-0.665） in predicting cognitive impairment in CSVD patients，with a sensitivity of 0.560 and a specificity of 0.659； LDL-C/HDL-C ratio had an AUC 0.617 （95%CI 0.558-0.676） in predicting cognitive impairment，with a sensitivity of 0.552 and a specificity of 0.762； TC/HDL-C ratio combined with LDL-C/HDL-C ratio had an AUC of 0.776 （95%CI 0.726-0.825） in predicting cognitive impairment，with a sensitivity of 0.772 and a specificity of 0.667. Conclusion Increases in TC/HDL-C ratio and LDL-C/HDL-C ratio are risk factors for cognitive impairment in CSVD patients and thus have a certain predictive value for cognitive impairment in CSVD patients，and the combination of these two ratios has a higher predictive value.
