Abstract/OtherAbstract:
We aimed to investigate the association between aortic distensibility (AD) and left ventricle myocardial performance index (MPI) in patients with newly diagnosed hypertension (HT). We studied 49 patients with HT and 24 healthy control subjects. AD was calculated from the echocardiographically derived ascending aorta diameters. The MPI was calculated from both conventional flow Doppler echocardiography and tissue Doppler echocardiography recordings. Conventional Doppler E/A and tissue Doppler derived Ea/Aa were determined for all the subjects. Aortic distensibility was lower, and both conventional and tissue Doppler MPI values were higher (p<0.001 for all) in patient group compared with control group. AD was correlated with systolic blood pressure (SBP) (beta=-0.436, p=0.037), Ea/Aa (beta=0.228, p=0.038) and tissue derived MPI (beta=-0.302, p=0.043) in multiple linear regression analysis. Aortic distensibility was independently related to tissue derived MPI and Ea/Aa besides SBP.
