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.
Additionally, more than 50% of people seek readmission within 6 months after treatment and the average duration of hospital stay is 6 days. Heart failure is a leading cause of hospital readmissions in the U.S. People aged 65 and older were readmitted at a rate of 24.5 per 100 admissions in 2011.
People with heart failure, also known as congestive heart failure (CHF), are educated to undertake various non-pharmacological measures to improve symptoms and prognosis. Such measures include: [2] Moderate physical activity, when symptoms are mild or moderate; or bed rest when symptoms are severe. In individuals with heart failure, increasing ...
For others, if the enlarged heart begins to affect the body's ability to pump blood, then symptoms associated with congestive heart failure may arise, including: [15] Heart palpitations – the irregular beating of the heart, usually associated with a valve; Severe shortness of breath (especially when physically active) Chest pain
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 ...
Cardiomyopathy is a group of primary diseases of the heart muscle. [1] Early on there may be few or no symptoms. [1] As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. [1] An irregular heart beat and fainting may occur. [1]
Treatments for heart failure include medications, an intra-aortic balloon pump, a ventricular assist device, heart valve replacements, extracorporeal membrane oxygenation (if the heart failure worsens suddenly and especially if an infection was the cause), an artificial heart, or a heart transplant (from a deceased human donor, or from a pig ...
Ischemic cardiomyopathy is the cause of more than 60% of all cases of systolic congestive heart failure in most countries of the world. [6] [8] A chest radiograph that demonstrates coronary artery calcification is a probable indication of ischemic cardiomyopathy. [9] The following are causes of ischemic cardiomyopathy: [1] Diabetes ...
