Adiponectin as an independent predictor of left ventricular hypertrophy in nondiabetic patients with hypertension

Abstract

We evaluated novel and traditional biomarkers as well as hemodynamic parameters associated with the development of left ventricular hypertrophy (LVH) in nondiabetic patients with hypertension. Nondiabetic patients with hypertension (n = 86) were evaluated for lipids, glucose, insulin, homeostasis model assessment-insulin resistance (HOMA-IR), adiponectin, aldosterone, renin, matrix metalloproteinase 2, and endothelin. Arterial elasticity was evaluated using pulse wave contour. The LVH parameters were assessed echographically. Adiponectin was significantly and inversely associated with left ventricular mass (LVM; P = .032). The aldosterone-renin ratio (ARR) was significantly, positively associated with LVM (P = .031). Fasting insulin as well as HOMA-IR was significantly, positively associated with LVM (P = .036 and P = .025, respectively). In multiple linear regression analysis, adiponectin and ARR remained a significant predictor of LVM. The present study found that adiponectin and ARR are important independent determinants of LVH in nondiabetic patients with hypertension.
