title: Plasma levels of von willebrand factor, endothelin-1, prostacyclin and thromboxane in children from families with high risk of premature coronary artery disease.
abstract: The aim of the study was to assess the plasma levels of endothelial injury markers in children from families with high risk of premature coronary heart disease (CHD) without other common CHD risk factors (hyperlipidaemia, obesity, hypertension, low physical activity). The study comprised 48 children, including 24 children from high-risk families (HR), according to the NCEP (National Cholesterol Education Programme) criteria: one or two parents had clinical manifestation of cardiovascular disease before the age of 65 years (mother) or 55 years (father). The control group included 24 healthy children with no familial history of cardiovascular disease. All the children were normolipidaemic according to the NCEP and the European Atherosclerosis Society criteria for children aged 2-19 years. In the HR group, the concentration of vWf was significantly elevated in comparison to that in the control group (p<0.0001). Plasma concentrations of ET-1 and TxB2 did not differ significantly between the HR group and the controls. Plasma concentrations of the 6-ketoPGF1alpha in the HR group and in the respective age and gender HR subgroups were significantly lower compared with those of the control group (p<0.00005). Concentration of vWf in the HR group was negatively correlated with the concentration of 6-ketoPGF1alpha (r = -0.47; p<0.05) and positively correlated with TxB2 (r=0.39; p<0.01). In a logistic regression analysis, we found that the 6-ketoPGF1alpha concentration in the lower quartile (< 16.1 pmol/L) was associated with a 3.4-fold odds of inclusion in the high-risk group versus the upper quartile (>23.0 pmol/L).
