Some biochemical changes in patients with acute ischemic stroke

Abstract

The aim was to determine the alterations in levels of vasculair endothelial growth factor (VEGF), homocysteine (HC) and lipid profile in patients with acute ischemic stroke (AIS), to establish the relationship between them. A clinical and neurological examination of 120 patients aged 56 to 75 years with AIS was done. Diagnosis was established taking into account results of spiral computer and magnetic resonance tomography. The control group included 20 people with no signs of acute cerebrovascular and severe somatic pathology aged 59.35±1.8 years. Assessment of disability was performed at admission and during the treatment using the scale NIHSS. In all relevant patients in 1-2 days after stroke, the concentration of HC and VEGF levels was determined by ElISA. Blood lipid profile was determined by enzymatic colorimetric method. The study found that increasing concentration of plasma HC is associated with intensity of hyperlipidemia, and hyper- homocysteinemia severity prevails over the changes in the lipid profile components. During AIS a significant increase in the level of VEGF in the blood was observed, indicating the presence of vascular accident and activation of angiogenesis. Severity of vascular endothelial lesions is associated with the degree of increasing concentration VEGF that appears most significant in patients with severe AIS.
