Primary aldosteronism (PA) has been associated with increased target organ damage (TOD), most likely through mineralocorticoid receptor-dependent endothelial dysfunction, in comparison with essential hypertension (EH). The aim of this study was to evaluate the level of biomarkers of endothelial dysfunction in PA and the relationship with left ventricular hypertrophy (LVH) and microalbuminuria (MAU). A total of 50 PA patients and 51 patients with EH individually matched for age, sex, blood pressure and duration of hypertension participated in this study. Biomarkers of endothelial dysfunction, including von Willebrand factor (vWF), intercellular adhesion molecule 1 (ICAM-1) and oxidized low-density lipoprotein (ox-LDL), were measured. Plasma aldosterone concentration (PAC), MAU and echocardiography were also evaluated. In PA patients, vWF, ICAM-1, ox-LDL, LVH and MAU were all significantly higher than in EH patients (all P<0.05). Furthermore, LVH was positively correlated with PAC (P=0.002), vWF (P=0.013) and ox-LDL (P=0.020). MAU was positively correlated with PAC (P<0.001), vWF (P=0.013) and ICAM-1 (P=0.001). Multiple regression analysis indicated that vWF, ICAM-1 and PAC independently predicted MAU (all P<0.05). Likewise, PAC, vWF and ox-LDL were significant predictors of LVH (all P<0.05). Taken together, our results suggest that endothelial dysfunction may contribute to TOD in PA patients.
