Talk:Heart failure with preserved ejection fraction

note
Language used to describe Heart Failure in medical writing, laboratory parameters, clinical studies, journals and imaging formulas is necessarily concise. HFpEF is perhaps the most accurate representation of diastolic heart failure yet devised. Conceptually it appears this formula is half mathematics and half physiology. As a contribution to encyclopedic documentation it should probably be first approved as an authentic medical term by the US Library of Congress Medicine. If approved the mathematical models that would follow are promising.

Merger proposal
This page covers the same topic as diastolic heart failure, and I believe both are synonyms for the same condition --Ben Best:Talk 21:10, 12 April 2016 (UTC)

I think it would be best to merge HFpEF and diastolic HF as diastolic HF is a largely dated term, however it might make sense to make a new page on diastolic dysfunction as many individuals suffer from diastolic dysfunction that never develops into heart failure.

Contradictory Information
Under the diastolic dysfunction header the following statements appear to contradict:

"Diastolic failure is characterized by an elevated diastolic pressure in the left ventricle, despite an essentially normal/physiologic end diastolic volume (EDV)."

"In diastolic heart failure, the volume of blood contained in the ventricles during diastole is lower than it should be, and the pressure of the blood within the chambers is elevated."

I propose that the statements on end diastolic volume and diastolic dysfunction be changed to something along the lines of: "Diastolic failure is characterized by an elevated left ventricular end diastolic pressure (EDP) despite a normal EDV at rest. The elevated resting EDP results in an impaired ability to elevate EDV upon exertion, thus reducing cardiac output."

This explanation is in-line with figure 5 of this 2011 review.

Definition of ejection fraction
I am a patient diagnosed with HFpEF, not a medical professional. The definition of ejection fraction provided in this article: “the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled” appears to be grammatically incorrect.

As the Wikipedia article on ejection fraction explains, ejection fraction is a percentage, measured by dividing one volume by another volume. This article appears to describe ejection fraction as a percentage divided by a volume. This is surely incorrect and confusing if not misleading.

Perhaps it could be better described as: "the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled, expressed as a percentage”. 94.105.118.252 (talk) 04:25, 29 December 2023 (UTC)
