ABSTRACT
Homocysteine (Hcy) is a sulfur-containing metabolic intermediate of methionine,which is normally at a lower level in the blood.Recent studies have shown that the elevated blood level of Hcy is an independent risk factor for ischemic stroke and increases the risk of occurrence of cerebral small vessel disease (CSVD).This article reviews the relationship between Hcy and CSCD.
ABSTRACT
Atrial fibrillation is a common type of arrhythmia. Cerebral microbleeds (CMBs) are a neuroimaging phenotype of cerebral small vessel disease, which is related to the tendency of intracranial hemorrhage. Studies have shown that the detection rate of CMBs in patients with atrial fibrillation is higher, and CMBs are also a risk factor for increasing the risk of stroke in patients with atrial fibrillation and death in patients with atrial fibrillation complicated with stroke. This article reviews the predictive factors of CMBs in patients with atrial fibrillation.
