title: [Humoral markers of endothelial dysfunction in essential hypertension].
abstract: OBJECTIVE
  To elucidate potential markers of endothelial dysfunction and relationships between humoral and vasoregulatory responses of the endothelium in patients with essential hypertension.
  
  
  METHODS
  Thirty four male patients (mean age 54.4+/-9.2) with I-II degree hypertension and left ventricular hypertrophy.
  
  
  METHODS
  Endothelial function was assessed non-invasively by registration of flow-mediated brachial artery dilatation. Serum level of vascular adhesive molecule 1S (VCAM-1S) was measured by enzyme immunoassay, levels of aldosterone and insulin-like growth factor-1 (IGF-1) - by radioimmunoassay.
  
  
  RESULTS
  Brachial artery flow mediated dilatation was 2.0+/-7.46%. Patients with hypertension compared with healthy subjects had significantly higher mean levels of VCAM-1S (713.9+/-123.2 and 590.8+/-51.8 pg/ml, respectively, p<0.001), aldosterone (105.41+/-50.17 and 42.7+/-13.16 ng/ml, respectively, p<0.001), and IGF (209.7+/-49.1 and 137+/-21 pg/ml, respectively, p<0.001). Direct significant correlations were found between humoral and functional markers of endothelial dysfunction in the group of patients with essential hypertension.
  
  
  CONCLUSIONS
  These results can be interpreted as indicative of pathogenetic role of IGF-1 and aldosterone in the development of the endothelial dysfunction and myocardial remodeling in essential hypertension
