Independent Correlation of Serum Homocysteine with Cerebral Microbleeds in Patients with Acute Ischemic Stroke due to Large-Artery Atherosclerosis

J Stroke Cerebrovasc Dis. 2016 Nov;25(11):2746-2751. doi: 10.1016/j.jstrokecerebrovasdis.2016.07.028. Epub 2016 Aug 20.

Abstract

Background and aim: The severity of cerebral microbleeds (CMBs) affected the prognosis of patients with acute cerebrovascular disease. Considering the impact of CMBs on clinical decision, it is necessary to assess the risk factors of CMBs. We aimed to evaluate the independent risk factors of CMBs in patients with acute ischemic stroke of large-artery atherosclerosis.

Materials and methods: 112 patients were enrolled in the study. The baseline information, the results of laboratory examination and cranial MRI were collected. The independent risk factors of CMBs in patients with acute ischemic stroke due to large-artery atherosclerosis were evaluated.

Results: CMBs were found in 56 (50%) patients. Older age and higher homocysteine (Hcy) level were associated with an elevated chance of occurrence of CMBs. Further, there was a positive correlation between CMBs grade and serum Hcy level.

Conclusions: Serum Hcy level is strongly associated with the presence of CMBs in patients with acute ischemic stroke due to large-artery atherosclerosis. Serum Hcy level may be a potential therapeutic target for alleviating adverse clinical outcomes of CMBs.

Keywords: Acute ischemic stroke; age; cerebral microbleeds; homocysteine; large-artery atherosclerosis.
