White adipose tissue in the lean (left) vs. obese (right) state
Adipocytes are shown with yellow triglyceride droplets and blue cytoplasm. In the lean state
the light blue cytoplasm represent a state of normoxia, whereas the dark blue in the obese state
represents a hypoxic state. Pre adipocytes are shown in brown, macrophages in green, blood
vessels/endothelial cells in red, and the extracellular matrix as black.

Clinical studies showed that:• in patients with essential hypertension plasma
adiponectin concentration is decreased,• high blood pressure values were related to low
plasma adiponectin concentration,• organ complications of essential hypertension
(left ventricular hypertrophy, diastolic left ventricular dysfunction, increased arterial stiffness, increased carotid artery intima-media thicknesses (cIMT), occurrence of higher grades of hypertensive retinopathy and albuminuria)were related to low plasma adiponectin concentration.

Can hypoadiponectinemia predispose to hypertension?
Decreased plasma adiponectin concentration in individuals with increased risk of hypertension:
in young normotensive men with a family history of essential hypertension,in young men with high-normal blood pressure (SBP 130–139 or DBP
85–89 mmHg),in individuals with prehypertension (SBP 120–139 or DBP 80–89
mmHg).
