P1007Aortic root diameters and aortic regurgitation in hypertensive patients and normal subjects

Purpose : The association between aortic root diameters and aortic regurgitation in hypertension (HT) is disputed with lack of understanding of the underline mehanisms lT. We investigate the relationship between aortic root diameters and aortic regurgitation in newly diagnosed and never treated hypertensive patients and in a group healthy subjects. Method: Participants were 175 hypertensives (42 F and 133 M) and 305 normotensives (134 F, 168 M) age matched (mean age 52.4±13 vs 52.6 ±15.2 years). Antropometric, office blood pressure (BP) measurements, a comprehensive echocardiography and local carotid stiffness study were performed. Aortic measures for annulus, sinuses of Valsalva, sinotubular junction and ascending aorta were taken in late diastole according to the leading edge method. The sinotubular junction/annulus ratio was calculated. Results: Hypertensive patients had significantly higher body surface area (BSA), systolic (SBP) and diastolic pressure (DBP), mean arterial pressure (MAP) and pulse?pressure (PP) (p
