Abstract:
Objective To investigate the correlation between plasma homocysteine (Hcy) level and cerebral microbleeds (CMBs) band leukoaraiosis (LA) in patients with acute stroke.Methods The clinical and imaging data of patients with acute stroke were analyzed retrospectively.The numbers of CMBs were counted and the severity of LA was graded according to the results of MRI.Fasting venous samples were obtained and the plasma Hey concentration was measured the next day after admission.Results A total of 139 patients with acute stroke were enrolled,67 of them were females and 72 were males (mean age 70.1 ± 10.2 years); 24 had hemorrhagic stroke and 115 had ischemic stroke.The age (76.23 ± 8.74 years vs.64.58 ± 7.42 years;t =4.621,P =0.012) hypertension ratio (89.13% vs.67.74% ;x2 =8.324,P =0.0 370) and plasma Hey level (14.53 ± 4.31 mmol/L vs.11.31 ±3.16 mmol/L;t =6.538,P=0.008| in a severe LA group (n=46) were significantly higher than those in a non-severe LA group (n =93).Spearman correlation analysis showed that there was significant correlation between the plasma Hcy level and the severity of LA (rs =0.365,P =0.002).Multivariate logistic regression analysis showed that the increased Hey level (odds ratio [ OR ],1.366,95%confidence interval [ CI] 1.141 - 1.526; P =0.010) and age (OR 1.093,95% CI 1.031 - 1.162; P =0.016)were the independent risk factors for severe LA.The age (74.37 ± 6.35 years vs.67.56 ± 8.52 years; t =6.628,P =0.038) and hypertension ratio (94.74% vs.62.20%;x2 =8.773,P =0.002) in a CBM group were significantly higher than those in a non-CMB group (n =82).Spearman correlation analysis showed that there was no significant correlation between the plasma Hcy level and the numbers of CBMs (rs =0.038,P =0.813).Multivariate logistic regression analysis showed that hypertension was an independent risk factor for CBMs.Conclusions The elevated plasma Hcy level was associated with LA,but it was not associated with CBMs.
