2. Heart failure with reduced ejection fraction - Wikipedia

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

   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] Other types of heart failure are heart failure with mildly reduced ejection fraction (LVEF between 40% and 50%) and heart failure with preserved ejection fraction (LVEF 50% or higher). [1] [3]

3. 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 ...

4. Heart failure - Wikipedia

   en.wikipedia.org/wiki/Heart_failure

   Left-sided heart failure may be present with a reduced ejection fraction or with a preserved ejection fraction. [10] Heart failure is not the same as cardiac arrest, in which blood flow stops completely due to the failure of the heart to pump. [12] [13] Diagnosis is based on symptoms, physical findings, and echocardiography. [6]

   Heart failure is categorized by a measurement known as ejection fraction. Ejection fraction is the amount of blood that the left ventricle of your heart pumps out each time it contracts.

6. Management of heart failure - Wikipedia

   en.wikipedia.org/wiki/Management_of_heart_failure

   Most hospitals have abandoned this operation and it is no longer included in heart failure guidelines. [50] Newer procedures under examination are based on the observation that the spherical configuration of the dilated heart reduces ejection fraction compared to the elliptical form.

7. Cardiac resynchronization therapy - Wikipedia

   en.wikipedia.org/wiki/Cardiac_resynchronization...

   This reduction in ejection fraction is considered heart failure. [2] Heart failure patients are generally considered if in New York Heart Association (NYHA) class II or III heart failure. Current National Institute for Health and Care Excellence (NICE) guidelines state that CRT-D device placement is inappropriate for class IV heart failure, but ...
