2. Heart failure with reduced ejection fraction - Wikipedia

   en.wikipedia.org/wiki/Heart_failure_with_reduced...

   Heart failure with reduced ejection fraction (HFrEF, hef-REF) is a form of heart failure in which the ejection fraction is reduced. [1] This is defined as a left ventricular ejection fraction (LVEF) of 40% or less. About half of heart failure patients have a reduced ejection fraction. [2]

3. Heart failure - Wikipedia

   HFrEF is associated with an ejection fraction less than 40%. [62] Heart failure with mildly reduced ejection fraction (HFmrEF), previously called "heart failure with mid-range ejection fraction", [63] is defined by an ejection fraction of 41–49%. [63] Heart failure with preserved ejection fraction (HFpEF): Synonyms no longer recommended ...

4. Heart failure with preserved ejection fraction - Wikipedia

   Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – 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 – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.

5. Ejection fraction - Wikipedia

   en.wikipedia.org/wiki/Ejection_fraction

   A heart which cannot pump sufficient blood to meet the body's requirements (i.e., heart failure) will often, but not invariably, have a reduced ventricular ejection fraction. [6] In heart failure, the difference between heart failure with a reduced ejection fraction, and heart failure with a preserved ejection fraction, is significant, because ...

   en.wikipedia.org/wiki/XXB_750

   XXB750 is an investigational drug developed by Novartis Pharmaceuticals, designed to treat resistant hypertension (rHTN) and heart failure with reduced ejection fraction (HFrEF). It functions as a natriuretic peptide receptor 1 (NPR1) agonist and is administered via subcutaneous injection.
