    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 ...

  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 ...

    In fact, a 2019 study at The Federal University of São Paulo concluded that moderate physical activity resulted in an increase in sleep efficiency and duration in adults diagnosed with insomnia. [34] The duration refers to the hours of sleep a person gets on a nightly basis, while the quality indicates how well or sufficient it was. [35]

    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.

  7. Pressure–volume loop analysis in cardiology - Wikipedia

    en.wikipedia.org/wiki/Pressure–volume_loop...

    Myocardial infarction or cardiomyopathy causes damage to the myocardium, which impairs the heart's ability to eject blood and, therefore, reduces ejection fraction. This reduction in the ejection fraction can manifest itself as heart failure. Low EF usually indicates systolic dysfunction, and severe heart failure can result in EF lower than 0.2 ...
