Diagnostic Value of Hcy Combined with Blood Pressure Variability Index in the Severity of Hypertension Complicated with CSVD and Its Correlation with Cognitive Function and CysC Expression

This paper explores the diagnostic value of Hcy combined with the blood pressure variability index in the severity of hypertension complicated with CSVD and its correlation with cognitive function and CysC expression. 200 patients with ischemic small cerebral vessels are selected as the research object. According to the MRI findings, they are divided into 48 cases of white matter lesions (WML), 44 cases of lacunar infarction (LI), 44 cases of enlarged perivascular spaces (EPVs), and 46 cases in the mixed group (referring to two or more types of ischemic cerebrovascular disease on imaging). Different cognitive domains of different types of ischemic cerebrovascular diseases are analyzed. The risk factors of cognitive decline in patients with ischemic cerebrovascular disease are analyzed by univariate analysis and multivariate logistic regression analysis. There is an ancestral correlation between serum Hcy and CSVD, which is an independent risk factor for CSVD.
