Elevated circulating sST2 associated with subclinical atherosclerosis in newly diagnosed primary hypertension
Abstract
The aims of this study were to measure the levels of interleukin-33 (IL-33) and soluble Suppression of Tumorigenicity 2 (sST2) in patients with newly diagnosed primary hypertension (HT) and to determine the relationship between carotid intima-media thickness (CIMT) and IL-33/sST2. Eighty-two patients with newly diagnosed primary HT and ninety healthy volunteers were included in the study. CIMT ⩾0.9 mm was considered as significant for subclinical atherosclerosis. The sST2 levels of patients with primary HT were higher than those of the control group, whereas the IL-33 levels of these patients were much lower than those of the control group. The sST2 levels were higher in patients with subclinical atherosclerosis than in control subjects or patients with primary HT but not with subclinical atherosclerosis. In the primary HT group, sST2 had a positive correlation with CIMT, 24-h systolic-diastolic blood pressure, low-density lipoprotein and C-reactive protein, whereas sST2 had a negative correlation with the IL-33 level. A stepwise multivariable logistic regression analysis revealed that sST2 is an independent risk factor for subclinical atherosclerosis. Although the diagnostic predictive value of HT risk was determined as >51.8 ...Continue Reading
