Indexes Derived From Non-linear ESPVR For
Evaluation Of Ventricular Performance
Author(s)
R. M. Shoucri
Abstract
Indexes derived from the non-linear end-systolic pressure-volume relation
(ESPVR) are introduced in a way to study the performance of the left ventricle
of the heart. The study sheds some light on the problem of heart failure with
normal or preserved ejection fraction (HFpEF). It is shown that the ejection
fraction (EF) is one index of several indexes that can be derived from the
ESPVR in order to assess the performance of the left ventricle. Pressures acting
on the left ventricle (ordinates of the ESPVR) as well as areas under the ESPVR
(units of energy) can be used in assessing the performance of the left ventricle.
Keywords: cardiac mechanics, mathematical physiology, pressure-volume
relation in the ventricles, peak isovolumic pressure, active force of the
myocardium, ventricular elastance, heart failure with preserved ejection
fraction.
