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.
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]
Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
Risk increases if the ejection fraction decreases or if the individual develops symptoms. [36] Individuals with chronic (severe) aortic regurgitation follow a course that once symptoms appear, surgical intervention is needed. AI is fatal in 10 to 20% of individuals who do not undergo surgery for this condition.
Paroxysmal nocturnal dyspnea is a common symptom of several heart conditions such as heart failure with preserved ejection fraction, in addition to asthma, chronic obstructive pulmonary disease, and sleep apnea. [8] Other symptoms that may be seen alongside paroxysmal nocturnal dyspnea are weakness, orthopnea, edema, fatigue, and dyspnea. [9]

Heart failure, both with and without preserved ejection fraction, though through different mechanisms, result in an increase in left ventricular end-diastolic pressure (LVEDP). [7] Because CPP is measured by the difference in aortic and LVEDP pressures, an increase in LVEDP will decrease CPP.
Stroke volume is an important determinant of cardiac output, which is the product of stroke volume and heart rate, and is also used to calculate ejection fraction, which is stroke volume divided by end-diastolic volume. Because stroke volume decreases in certain conditions and disease states, stroke volume itself correlates with cardiac function.
