Introduction: Arterial stiffening may contribute to the increase of left ventricular mass (LVM) and the development of left ventricular hypertrophy (LVH). Although male gender has been also found to be an independent determinant of LVH, it is unknown if the adverse effect of increased aortic stiffening on LVM differs between males and females.

Aim: To evaluate the association of aortic stiffness as assessed by carotid-to-femoral pulse wave velocity (cf-PWV) with LVM and LVH in a general population and compare these associations between males and females.

Methods: Demographic, laboratory and clinical data of 1686 subjects (693 males and 993 females) from the cross-sectional, observational study “Corinthia” were analyzed. All subjects underwent applanation tonometry and pulse wave analysis for the measurement of cf-PWV and echocardiography examination for the computation of LVM which was adjusted by body surface area providing the LVM index (LVMI). Multivariate linear regression analysis was performed for the determination of independent factors related with LVMI. Receiver operator curve analysis (ROC) was used to compare the ability of cf-PWV to predict LVH, in males and females separately.

Results: In the female population, significant and independent determinants of LVMI were: age (beta=0.243, p<0.001), urea (beta=0.119, p=0.001), hypertension (beta=0.089, p=0.028) and cf-PWV (beta=0.096, p=0.021). In contrast, in the male population, LVMI was independently related with age (beta=0.242, p<0.001), systolic blood pressure (beta=0.095, p=0.027), LDL (beta=-0.087, p=0.047) and creatinine (beta=0.092, p=0.031). ROC analysis showed that cf-PWV is a stronger predictor of LVH in females than in males (figure).

Conclusion: Increased aortic stiffness measured by cf-PWV is significantly related with increased LVMI regardless from age and other risk factors only in females. Moreover cf-PWV was a stronger predictor of left-ventricular hypertrophy in females than males. These findings should be further explored in prospective studies.
