Abstract

Much evidence suggests sexual dimorphism in the relationship linking blood pressure (BP) to both left ventricular mass (LVM) and geometry in hypertension. To better evaluate gender-associated characteristics in the relation BP-LVM among newly diagnosed hypertension (24-h average ambulatory BP monitoring, ABPM, > 125/80 mmHg), we measured indexed LVM and relative wall thickness (RWT) by standardized echographic methods in 209 Caucasian drug-naïve subjects, of whom 162 (100M/62F) were recognized to be hypertensive. Mean office systolic (SBP)/diastolic (DBP), 24-h average and night-time BP values were similar between sexes and significantly related to indexed LVM in both genders. Daytime SBP was significantly related to indexed LVM only in females (r = 0.41; p = 0.0008 in women; r = 0.11; p = NS in males), while LVM was more sensitive to day-to-night SBP change in females. RWT was, on the contrary, significantly related to ABPM values only in males. All these findings were confirmed after adjusting for possible confounders. Percentage of LVM variance explained by 24-h average, daytime or night-time SBP values were higher in females than in males (17% vs 3%; 11% vs 1%; and 17% vs 8%). In conclusion, in early hypertension, LVM was significantly associated with daytime BP and more sensitive to reduced percentage of night BP fall in females. LVM variance explained by ABPM SBP was much higher in females than in males. RWT, expressing concentric LVM remodelling was, conversely, more related to BP increase in males.
