Key result
End-systolic pressure-volume relation (ESPVR) parameters can derive multiple new indices beyond ejection fraction to better understand heart failure with preserved ejection fraction.

ESPVR-derived indices may refine HFpEF phenotyping; hypothesis-generating and should not yet change practice.
In this study, the end-systolic pressure-volume relation (ESPVR) is used to derive new criteria that can help understand the problem of heart failure with normal or preserved ejection fraction (HFpEF). It is shown that the ejection fraction (EF) is just one index of several indexes that can be derived from the parameters describing the ESPVR and related areas under ESPVR.
