[53] [54] The multicenter RESTORE trial of 1198 participants demonstrated an increase in ejection fraction from about 30% to 40% with a concomitant shift in NYHA classes, with an early mortality of 5% and a 5-year survival of 70%. [55] It remains unknown if surgery is superior to optimal medical therapy.
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 ...
Because there is no evidence that prolapse has contributed to these arrhythmias, these complications may be due to mitral regurgitation or congestive heart failure. [20] The incidence of life-threatening arrhythmias in the general population with MVP remain low. [21] Sudden cardiac death results in 0.2% to 0.4% patients per year. [22]
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 include "diastolic heart failure" and "heart failure with normal ...
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.
Prognosis: Five-year survival rate ~50% [9] ... [20] [21] Genetics ... This process is usually associated with a continuous decline in ejection fraction. The concept ...
In clinical cardiology the term "diastolic function" is most commonly referred as how the heart fills. [1] Parallel to "diastolic function", the term "systolic function" is usually referenced in terms of the left ventricular ejection fraction (LVEF), which is the ratio of stroke volume and end-diastolic volume.

Survival rate is a part of survival analysis.It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions, and can be used for the assessment of standards of therapy.
