The level of adropin and von Willebrand factor in patients with arterial hypertension, excess body weight, and obesity

Abstract

Objective. To investigate changes in adropin and von Willebrand factor (vWF) levels in patients with arterial hypertension (AH), excess body weight, and obesity.Material and methods. All patients were divided into two main groups: group 1 included 69 patients with AH and excess body weight; group 2 – 55 people with AH and obesity, and 20 healthy people of the control group. Anthropometric measurement, biochemical blood test, echocardiographic examination of the heart, and enzyme immunoassay (adropin, vWF) were performed.Results. The level of vWF was significantly higher in patients with AH, overweight, and obesity compared to healthy individuals (p=0,001). Meanwhile, the adropin level decreased with increasing BMI. The lowest adropin level was observed in individuals with AH and obesity (p=0,011). Additionally, a significant positive correlation was identified between vWF and the size of the LA (r=0,667; p=0,001), RV (r=0,487; p=0,021), MMLV (r=0,795; p=0,001) and IMMLV (r=0,731; p=0,001), whereas a negative correlation was found with EF (r=-0,461; p=0,031).Conclusions. An increase in vWF level was observed in patients with hypertension, overweight, and obesity which contributes to the emergence of endothelial dysfunction and structural myocardial changes, related to AH. The decrease in adropin level – a regulator of the cardiovascular system functions – was associated with an increase in BMI and elevated BP. Negative correlations were found between adropin and systolic and diastolic blood pressure values. It plays an important role in blood pressure and cardiovascular function regulation.
