The relation between mitral annulus motion and ejection fraction: a nonlinear function.

K Emilsson1, M Alam, B Wandt.   

Abstract

In previous studies of the relation between mitral annulus motion (MAM) and left ventricular ejection fraction (EF), a linear relationship has been suggested. In this meta-analysis of 434 patients, we show that the relation is nonlinear and that a linear regression model overestimates EF in the lower range of MAM. The relation is better described by an S function and is influenced by age and heart size.
