    Abstract:
    BACKGROUND: Although gender-related differences in ventricular remodeling and arterial stiffness have been described, the impact of gender on the association between vascular compliance and left ventricular hypertrophy (LVH) has not been investigated. The current study was designed to determine the gender-related differences in the association between echographically determined LVH measures and arterial stiffness in hypertensive men and women. METHODS: In the current study, 104 hypertensive participants (61 men and 43 women) were enrolled. Large artery elasticity index (LAEI) and small artery elasticity index (SAEI) were determined using pulse wave contour analysis (HDI CR 2000, Eagan, Minnesota). Left ventricular hypertrophy parameters including intraventricular septum thickness (IVST), posterior wall thickness (PWT), and left ventricular mass index (LVMI) were assessed echographically. RESULTS: Hypertensive male versus female were similar in terms of age, body mass index (BMI), blood pressure, concomitant medications, and cardiovascular risk factors. Left ventricular mass index was significantly, inversely associated with IVST (r = -.32, P = .01), PWT (r = -.32, P = .01), and LVMI (r = -.28, P = .03) in men and significantly, inversely associated with IVST (r = -39, P = .01), PWT (r = -.42, P = .005), LVMI (r = -.54, P < .0001) in women. Small artery elasticity index was significantly, inversely associated with LVMI (r = -0.36, P = .02) in women only. In regression analysis, LAEI explained more variability than SAEI and was an independent predictor of LVH parameters in hypertensive men and women. CONCLUSIONS: Compliance of large arteries is potentially an independent predictor of LVH in hypertensive men and women. Therefore, arterial compliance is being considered an important tool in predicting LVH in hypertensive participants.
