'''Injection fraction''', IF=EDV/ESV, is the inverse operation of the [[myocardial]] [[ejection fraction]]. "Ejection Fraction" is historically and mathematically derived from [[Cardiac Output]] first posited by [[Adolph Fick]] 1829-1901. Ejection fraction (EF) is most readily appreciated as the difference between [[end systolic volume]] and [[end diastolic volume]]. Mathematical derivation as [[stroke volume]] and [[minimum volume]] or MinV similarly apply as determinants of [[Systole (medicine)|Systole]].

Ejection Fraction is noninvasively and inexpensively reproduced echocardiographically in many languages as EF=ESV/EDV.

Determinants of [[Diastole]] implies an inverse mathematical approach to the work of Fick. Injection fraction as a determinant of diastole is the difference between end diastolic volume and end systolic volume. IF=EDV/ESV. Decline of injection fraction further implies a measurable determinant of diastolic heart failure.

Decline of injection fraction will likely closely follow clinically relevant time ratios such as E:A intervals across the mitral valve.

It can be measured with a [[MUGA scan]].<ref name="pmid12862017">{{cite journal |author=Mininni NC, Tasota FJ |title=Measuring injection fraction with a MUGA scan |journal=Nursing |volume=33 |issue=7 |pages=26 |year=2003 |month=July |pmid=12862017 |doi= |url=http://meta.wkhealth.com/pt/pt-core/template-journal/lwwgateway/media/landingpage.htm?issn=0360-4039&volume=33&issue=7&spage=26}}</ref>

<!--what's this? Mininni/Tasota - Your early MUGA evidence of diastolic heart failure is compelling and valuable to the ongoing discussion. -->
