Ventriculo‐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 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 کاملArterial 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 کاملVentriculo-arterial coupling and the areas under the end-systolic pressure-volume relation.
Ventriculo-arterial coupling is expressed as the ratio Emax/eam (maximum ventricular elastance/arterial elastance). Different areas under the end-systolic pressure-volume relation (ESPVR) are expressed in terms of Emax/eam. The explicit inclusion of the active force of the myocardium in the mathematical formalism describing the pressure-volume relation (PVR) leads to new insight into the mechan...
متن کاملRight ventricular pulsatile afterload and right ventriculo-arterial coupling in pulmonary hypertension
Contact address: Ruxandra Jurcut, Cardiology Department, Emergency Institute for Cardiovascular Diseases “Prof. Dr. C. C. Iliescu”, Sos. Fundeni 258, Sector 2 022328 Bucuresti, Romania e-mail: [email protected] INTRODUCTION In pulmonary hypertension (PH), right ventricular (RV) function is correlated with functional status and is a strong predictor of survival, whereas the pulmonary artery (PA)...
