2. Heart failure with preserved ejection fraction - Wikipedia

   en.wikipedia.org/wiki/Heart_failure_with...

   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.

3. Ejection fraction - Wikipedia

   en.wikipedia.org/wiki/Ejection_fraction

   An ejection fraction (EF) is the volumetric fraction (or portion of the total) of fluid (usually blood) ejected from a chamber (usually the heart) with each contraction (or heartbeat). It can refer to the cardiac atrium , [ 1 ] ventricle , [ 2 ] gall bladder, [ 3 ] or leg veins, [ 4 ] although if unspecified it usually refers to the left ...

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. Pathophysiology of heart failure - Wikipedia

   en.wikipedia.org/wiki/Pathophysiology_of_heart...

   Whilst left-sided heart failure will reduce cardiac output to the systemic circulation, the initial symptoms often manifest due to effects on the pulmonary circulation. In systolic dysfunction, the ejection fraction is decreased, leaving an abnormally elevated volume of blood in the left ventricle.

8. Management of heart failure - Wikipedia

   en.wikipedia.org/wiki/Management_of_heart_failure

   The RALES trial [30] showed that the addition of spironolactone can improve mortality, particularly in severe cardiomyopathy (ejection fraction less than 25%.) The related medication eplerenone was shown in the EPHESUS trial [ 31 ] to have a similar effect, and it is specifically labelled for use in decompensated heart failure complicating ...

9. High-output heart failure - Wikipedia

   en.wikipedia.org/wiki/High-output_heart_failure

   High-output heart failure is a heart condition that occurs when the cardiac output is higher than normal because of increased peripheral demand. There is a circulatory overload which may lead to pulmonary edema secondary to an elevated diastolic pressure in the left ventricle .
