Arterial and Ventricular Elastance and Ventriculo-arterial Coupling in Asthmatic Children.
OBJECTIVE To compare arterial and ventricular end-systolic elastance and ventriculo-arterial coupling between asthma and healthy children and correlate these all three parameters with pulmonary function tests in subjects with asthma. STUDY DESIGN Across-sectional analytical study. PLACE AND DURATION OF STUDY Department of Pediatrics, Bozok University Medical Faculty,Yozgat, Turkey, from Jan...
متن کاملEffects of nicardipine on ventriculo-arterial coupling in humans.
The ratio of effective arterial elastance (Ea) to left ventricular elastance (Ees) is an indicator of the coupling between ventricular properties and arterial load properties. Another criterion for the coupling between an energy source and its load is the principle of economical fuel consumption, or mechanical efficiency, which is defined as the ratio of stroke work (SW) to myocardial oxygen co...
متن کاملVentriculo‐arterial coupling in children with Still's murmur
Still's murmur is the most common innocent heart murmur in children and considered flow related; however, so far the cause of the murmur has not yet been fully explained. Assessment of the hemodynamic ventriculo-arterial interaction and the proportional anatomical dimensions of the left ventricle and the aortic root were the objective for this study. This case-control study was conducted at the...
متن کامل0590. Impact of arterial tone changes on dynamic arterial elastance and the arterial pressure response to fluid administration
Introduction Dynamic arterial elastance (Eadyn), the relationship between pulse pressure variation (PPV) and stroke volume variation (SVV), has been suggested as a functional assessment of arterial load for predicting the arterial pressure response after volume expansion (VE). Although changes in Eadyn have been related with variations in arterial load, the effect of acute arterial tone changes...
متن کاملArterial elastance and heart-arterial coupling in aortic regurgitation are determined by aortic leak severity.
BACKGROUND In aortic valve regurgitation (AR), aortic leak severity modulates left ventricle (LV) arterial system interaction. The aim of this study was to assess (1) how arterial elastance (E(a)), calculated as the ratio of LV end-systolic pressure and stroke volume, relates to arterial properties and leak severity and (2) the validity of E(a)/E(max) (with E(max) the slope of the end-systolic ...
