“…A standard 2D Doppler echocardiographic study with ASI measurement was carried out in all subjects with a commercially available echocardiography system (Toshiba Artida™, Toshiba Medical Systems, Tokyo, Japan) using a 1-5 MHz PST-30SBP phased-array transducer. LV internal dimensions and systolic (SD) and diastolic (DD) ascending aortic diameters 3 cm above the aortic valve were measured by M-mode echocardiography in parasternal long-axis view (8,9) (Fig. 1).…”

“…LV strains are quantitative features of LV deformation, which could easily be determined by three-dimensional (3D) speckle-tracking echocardiography (3DSTE) (1,11). Echocardiographic aortic elastic properties could be assessed simultaneously with LV strain measurements allowing us to find relationship between LV and aortic functions (8,9). Due to the fact that sport activity is frequently associated with changes in both LV and arterial functions, the correlations were aimed to be found between 3DSTE-derived segmental LV strains and echocardiographically assessed aortic stiffness index (ASI) in the elite athletes in this study.…”

Introduction Myocardial contractility of the left ventricle (LV) is related to arterial distensibility. Sport activity is frequently associated with changes in both LV and arterial functions. This study aimed to find correlations between three-dimensional speckle-tracking echocardiography-derived segmental LV deformation parameters and echocardiographically assessed aortic stiffness index (ASI) in athletes. This study comprised 26 young elite athletes (mean age: 26.7 ± 8.4 years, nine men). Results Among segmental circumferential strains (CSs), only that of apical anterior (r = 0.40, p = 0.05), septal (r = 0.47, p = 0.01), inferior (r = 0.59, p = 0.001), lateral (r = 0.44, p < 0.05), and midventricular anteroseptal (r = 0.44, p < 0.05) segments correlated with ASI, whereas LV-CS of the midventricular anterior segment showed a correlation tendency. Only longitudinal strain of basal anteroseptal (r = -0.46, p < 0.05) and inferoseptal (r = -0.57, p < 0.01) segments showed correlations with ASI, whereas that of the basal anterior segment had only a tendency to correlate. Some segmental multidirectional strains also correlated with ASI. Conclusions Correlations could be demonstrated between increased aortic stiffness and circular function of the apical and midventricular LV fibers and longitudinal motion of the basal septum and LV anterior wall (part of LV outflow tract) in maintaining circulation in the elite athletes.

“…Increased arterial stiffness is one of the earliest indicators of vascular dysfunction, an important cardiovascular risk factor and a predictor of clinical outcomes (8,9). Using echocardiographically assessed aortic diameter data respecting cardiac cycle in combination with forearm blood pressure values, a number of echocardiographic aortic elasticity parameters could be calculated (4,7).…”

Background: Persistent eosinophilia and eosinophil-mediated single-or multiple-organ damage are typical features of hypereosinophilic syndrome (HES). Theoretically, eosinophilic infiltration of the ascending aortic wall could not be excluded in HES, therefore the present study aimed to test whether HES is associated with abnormalities in aortic elastic properties.Methods: The present study comprised 10 HES patients (mean age: 57.6±10.1 years, 5 males) without

Hypertrophic cardiomyopathy is a hereditary, not uncommon cardiac disease, which is associated with asymmetric thickening and hypertrophy of the interventricular septum unrelated to hemodynamic reasons. Despite hypertrophic cardiomyopathy is considered to be a disorder of the heart muscle, several associated vascular alterations have been described. The aim of the present review is to summarize vascular functional alterations in hypertrophic cardiomyopathy.
