Sažetak
Adiponectin, secreted by fat tissue, is down – regulated in obesity and may be involved in obesity-related disorders. It
has anti-inflammatory, antiatherosclerotic and antidiabetic effect. Obesity is a strong predictor for hypertension and cardiovascular
diseases. Recent studies showed that adiponectin level has important role in metabolic disorders, arterial
hypertension and ischemic heart disease but its effect on left ventricular hypertrophy (LVH) has not been fully clarified.
The aim of this research is to determine whether the protective effect of adiponectin against development of left ventricular
hypertrophy is decreased in hypertensive overweight patients. The study included 61 adult, overweight hypertensive
patients, with body mass index in range 25–30 kg/m2. Patients had regular morning glucose serum values and regular
creatinine level. They were divided into four groups, according to sex and the presence of LVH. There were 16 female and
15 male hypertensive patients with LVH and 15 female and 15 male hypertensive patients without LVH, who were a control
group. Glucose profile, lipidogram, creatinine clearance and anthropometric measures were determined in all patients.
Cardiovascular measurements were taken applying two-dimensional ultrasound. Adiponectin serum level was
measured using enzyme immunoassay (ELISA). Results showed that adiponectin serum level was significantly lower in
hypertensive, overweight females and males with LVH than in the control groups without LVH. Adiponectin serum level
did not correlate significant with intraventricular or with posterior wall thickness of left ventricle. Hypoadiponectinemia
presents part of neurohumoral, non-haemodynamic system who contributes to obesity-related hypertension and left ventricular
hypertrophy development. Low adiponectin level together with others adipokines, cytokines and chemokines secreted
by fat tissue could contribute to pathophysiologic changes of the myocardium via unknown molecular mechanisms
yet.
