Abstract:
Objective To analyze the relationship of total imaging burden score with blood pressure variability(BPV)and cognitive function in elderly patients with cerebral small vessel disease(CSVD).Methods Clinical data of 182 elderly CSVD patients admitted in our hospital from December 2022 to January 2024 were collected and analyzed retrospectively.According to the results of Chinese Guidelines for Diagnosis and Treatment of CSVD-Related Cognitive Dysfunc-tion(2019),Montreal Cognitive Assessment(MoCA)and other tools for their cognitive impair-ment,they were divided into cognitively impaired group(76 cases)and cognitively normal group(106 cases).The total burden score and BPV indicators[24 h systolic blood pressure coefficient of variation(24 h SBPCV),24 h diastolic blood pressure coefficient of variation(24 h DBPCV)]were compared between the two groups.ROC curve was plotted to evaluate the diagnostic value of total burden score,24 h SBPCV and 24 h DBPCV on cognitive impairment in elderly CSVD patients.Multivariate logistic regression analysis was used to identify the risk factors of cognitive impairment in the patients.Based on the MoCA score of the cognitively impaired group,these pa-tients were further assigned into mild and moderate-to-severe cognitive impairment subgroups[with a MoCA score of 18-25(43 cases)and＜18(33 cases),respectively].Then the total burden score,24 h SBPCV and 24 h DBPCV were compared between the two subgroups.Pearson correla-tion coefficient was adopted to evaluate the correlation of severity of cognitive impairment with total burden score,24 h SBPCV and 24 h DBPCV in the elderly CSVD patients.Results The total burden score,24 h SBPCV and 24 h DBPCV were significantly higher in the cognitively impaired group than the cognitively normal group(P＜0.01).ROC curve analysis indicated that total bur-den score(AUC=0.953,95％CI:0.926-0.980,P=0.000),24 h SBPCV(AUC=0.850,95％CI:0.795-0.906,P=0.000)and 24 h DBPCV(AUC=0.761,95％CI:0.690-0.832,P=0.000)had good diagnostic efficiency for cognitive impairment in the elderly CSVD patients,with a cut-off value of 1.5,11.82％,and 8.92％,respectively.Multivariate logistic regression analysis revealed that the above three indicators were risk factors for cognitive impairment in the elderly patients with CSVD(P＜0.05,P＜0.01).Their values were significantly lower in the mild than the moder-ate-to-severe cognitive impairment subgroups(P＜0.01).Pearson correlation analysis displayed that MoCA score was negatively correlated with total burden score,24 h SBPCV and 24 h DBPCV in elderly patients with CSVD(r=-0.755,-0.632,-0.601,P＜0.01).Conclusion Detection of total burden score and BPV indicators is beneficial to the assessment of cognitive impairment in elderly CSVD patients.The higher the total burden score and the greater the BPV indicators,the more severe the cognitive impairment is,which may explore new ideas for clinical diagnosis and treatment of CSVD.
