J Clin Hypertens (Greenwich) . 2011;13:710–715. ©2011 Wiley Periodicals, Inc. The authors investigated whether high‐density lipoprotein (HDL) cholesterol plays a role in arterial stiffening and left diastolic dysfunction in essential hypertension. Carotid arterial stiffness parameter and left ventricular (LV) diastolic function index were evaluated in 217 patients with essential hypertension. The correlations of dyslipidemia, especially low HDL cholesterol, to LV diastolic function and arterial stiffness were investigated in these patients. Arterial stiffness parameter increased with the increasing of E/Em (LV diastolic function index: the ratio of transmitral peak velocity of early filling to peak early diastolic motion velocity of mitral annulus) ( r =0.26, P <.01). In univariate regression analysis, HDL cholesterol was inversely associated with arterial stiffness parameter and E/Em ( r =−0.23 and r =−0.27, respectively, P <.01). The association of HDL cholesterol with arterial stiffness and LV diastolic function was observed in both men and women. Triglycerides were weakly correlated with arterial stiffness parameter and E/Em, while low‐density lipoprotein and total cholesterol were not. In multiple regression analysis, only low HDL cholesterol was found as an independent predictor for both arterial stiffness and LV diastolic dysfunction. Enhanced arterial stiffness is associated with LV diastolic dysfunction. Low HDL cholesterol may lead to the deterioration of both arterial stiffness and LV diastolic function in patients with essential hypertension.
