Cerebrovascular Reactivity to <i>L-</i>Arginine in Patients with Lacunar Infarctions

Abstract

Our results showed that cerebrovascular reactivity to L-arginine, which demonstrates cerebral endothelial function, is significantly impaired in patients with cardiovascular risk factors. Importantly, we found that patients with lacunar infarctions do not show any additional impairment of cerebral endothelial function.
