BACKGROUND: Vascular endothelial growth factor-A (VEGF-A) is a protein that plays a role in the formation and function of blood vessels, promotes increased vascular permeability or migration of monocytes through endothelial layers. AIM: We have tested the hypothesis that plasma levels of VEGF-A may be associated with biochemical and radiological parameters as a marker of cardiovascular risk in Caucasian patients with early-onset CAD.
METHODS: The study group included 100 patients: 75 men - not older than 50 years and 25 women - not older than 55 years at the moment of CAD diagnosis. The control group - the patients without CAD - comprised 50 healthy cases. ELISA test was used to measure plasma concentrations of VEGF. Doppler ultrasound of carotid and peripheral arteries was carried out in each patient. Serum glucose, complete lipid profile, ApoA1, ApoB, Lp(a) and blood count were measured in each case.
RESULTS: Only very weak correlations of plasma VEGF levels with biochemical cardiovascular risk factors in the CAD subjects have been demonstrated. In the study group, VEGF concentration was significantly positively correlated with the same blood parameters as white blood cells, platelets, plateletcrit, apolipoprotein B, total and LDL cholesterol fraction. The plaque of common carotid arteries and bifurcation was present in 39% of CAD patients, however, there was no significant association between VEGF plasma concentration and any measured parameters in Doppler ultrasound of carotid and peripheral arteries.
CONCLUSIONS: The circulating VEGF is only marginally associated with an increased risk for atherosclerosis.
