Echocardiography has emerged as the preferred modality by which diastolic function (DF) is
assessed for clinical or research purposes. Echocardiographic indexes and parameters of
DF such as E/A, DT, E/E', etc., deteriorate with advancing age. Whether the efficiency of
filling depends on age is unknown. To better characterize the filling process and DF in
causal rather than correlative terms, we have previously modeled diastole kinematically. We
introduced and validated a dimensionless measure of DF termed the kinematic filling …
