title: Serum soluble RAGE level inversely correlates with left ventricular hypertrophy in essential hypertension patients.
abstract: Soluble receptor for advanced glycation end-products (sRAGE) acts as a decoy to prevent interaction between RAGE and its pro-inflammatory ligands. sRAGE levels have been found to decrease in chronic inflammatory diseases, including hypertension. However, few data have been reported concerning the association between serum sRAGE levels and hypertensive left ventricular hypertrophy (LVH). Fasting blood samples were obtained from 209 essential hypertensive patients, and sRAGE levels were measured using a commercially available double-sandwich enzyme-linked immunosorbent assay kit. All patients underwent complete transthoracic echocardiographic examination. LVH was defined as a left ventricular mass index >115 g/m(2) for men and >95 g/m(2) for women. Eighty-one hypertensive patients (38.76%) were categorized in the LVH(+) group. Age (P = 0.009), hypertension duration (P = 0.013), triglyceride levels (P = 0.028), and systolic blood pressure (P = 0.026) were higher, and sRAGE and high-density lipoprotein cholesterol levels were lower in the LVH(+) group compared with the LVH(-) group. Multivariate logistic regression analysis showed that sRAGE level [odds ratio (OR) = 0.916; 95% confidence interval (CI) = 0.864-0.984; P = 0.003], hypertension duration (OR = 1.024; 95%CI = 1.003-1.052; P = 0.027), and triglyceride level (OR = 1.017; 95%CI = 1.005-1.039; P = 0.018) were independent predictors of LVH in hypertensive patients. In conclusion, serum sRAGE level was inversely associated with LVH in hypertensive patients.
