The aim of this study was to evaluate the influence of sex on cardiovascular hemodynamics and heart remodeling in 144 patients with arterial hypertension that underwent: (1) echocardiography (that is, indices of left ventricular diastolic function: e', E/e'), (2) impedance cardiography (that is, systemic vascular resistance (SVR), total artery compliance (TAC) and Heather index (HI)) and (3) applanation tonometry (augmentation index (AI), central systolic and diastolic blood pressure (CSBP, CDBP), central pulse pressure (CPP)). Women, in comparison with men, revealed to have: (1) stiffer arteries--lower TAC (1.93±0.55 vs 2.16±0.59 ml per mm Hg; P=0.025), higher CSBP (128.7±14.9 vs 123.4±13.2 mm Hg; P=0.036), CPP (39.9±9.5 vs 33.8±9.0 mm Hg; P=0.0002), AI (31.5±8.7 vs 17.5±12.7%; P<0.00001), SVR (1257.6±305.6 vs 1091.2±240.7 dyn × s × cm(-)(5); P=0.002) and (2) higher left ventricular performance--HI (16.3±4.3 vs 11.7±3.2 Ohm  × s(2); P<0.00001). In women CSBP, CPP and AI were more clearly associated with left ventricular filling pressure (e') (r=-0.39, r=-0.45, r=-0.44, P<0.01; respectively). These relations were remarkably weaker in men. Hypertensive women characterized with lower large artery compliance, more pronounced augmentation of central blood pressure and more distinctive association of central blood pressure with left ventricular diastolic function. Sex differences in cardiovascular function can impact the individualized management of arterial hypertension.

BP (27.3% vs. 12.1%; p = 0.013). More pronounced improvement in the left ventricular diastolic dysfunction (delta E/A 0.34 vs. 0.12, p = 0.017) (Cardiol J 2016; 23, 2: 132-140)
