Sep 10, 2016. Contractility is best measured by the slope, Emax, of the end-systolic pressure– volume relationship. Ventricular systole is usefully characterized.

Compliance is the ability of a hollow organ (vessel) to distend and increase volume with increasing transmural pressure or the tendency of a hollow organ to resist recoil toward its original dimensions on application of a distending or compressing force. It is the reciprocal of "elastance", hence elastance is a measure of the tendency of a hollow.

Systolic dysfunction refers to impaired ventricular contraction (loss of inotropy). In chronic heart failure, this is most likely due to changes in the signal transduction mechanisms regulating cardiac excitation-contraction coupling.The loss of cardiac inotropy (i.e., decreased contractility) causes a downward shift in the Frank-Starling.
