Arterial hypertension, insulin resistance, diabetes mellitus are associated with obesity. However exact mechanisms of this association have not been determined yet. Biologically active substances produced by adipose tissue participate in pathogenesis of cardiovascular diseases and complications. In this review we present data on the role of adiponectin - adipocytokine with unique antiatherogenic, antiinflammatory, and insulin sensitizing properties. Hypoadiponectinemia is considered to be potentially modifiable cardiovascular risk factor and novel therapeutic target. Therapy with PPAR gamma agonists, blockers of renin-angiotensin and sympathetic nervous systems is associated with elevation of concentration of adiponectin.
