Ejection fraction — the number that decides the whole regimen Not known
hf-ef-unknownNo one has reached this rule yetGet the number from an echocardiogram — nothing above can be chosen without it
No clinician has signed off this rule yet. It reflects our reading of the guidelines cited below, which has not been independently checked.
Word for word, as generated for the example person below. Figures in the text are theirs.
Find out your ejection fraction. It's one number from an echocardiogram, and it decides your entire treatment.
Ejection fraction is the percentage of blood the heart pushes out with each beat. Below 40% there are four drug classes that each help people live longer, and the goal is to be on all four. At 50% and above the treatment is different and much of it is about treating what caused it. Without this number nobody can tell you which set you belong in — including this page. Ask your doctor's office for the number from your most recent echo; it's on the report.
