Heart failure (HF), also known as congestive heart failure (CHF), is a syndrome caused by an impairment in the heart's ability to fill with and pump blood.. Although symptoms vary based on which side of the heart is affected, HF typically presents with shortness of breath, excessive fatigue, and bilateral leg swelling. [3]
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.
Studies show that left ventricular function often improves within 1 month of treatment of the tachyarrhythmia, and normalization of the left ventricular ejection fraction occurs in the majority of patients by 3 to 4 months. [1] [5] In some patients however, recovery of this function can take greater than 1 year or be incomplete. [5]
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 ...
The progression of heart failure is associated with left ventricular remodeling, which manifests as gradual increases in left ventricular end-diastolic and end-systolic volumes, wall thinning, and a change in chamber geometry to a more spherical, less elongated shape. This process is usually associated with a continuous decline in ejection fraction
Individuals with poor kidney perfusion are especially at risk for kidney impairment inherent with these medications. [15] Beta-blockers. Beta-blockers are stopped or decreased in people with acutely decompensated heart failure and a low blood pressure. However, continuation of beta-blockers may be appropriate if the blood pressure is adequate. [16]
To better understand diastolic function, it is crucial to realize that the left ventricle is a mechanical suction pump at, and for a little while after, the mitral valve opening. [5] In other words, when mitral valve opens, the atrium does not push blood into the ventricle, instead, it is the ventricle that mechanically "sucks" in blood from ...
Weight reduction – through physical activity and dietary modification, as obesity is a risk factor for heart failure and left ventricular hypertrophy. Effective weight management has been shown to significantly improve the heart's functional status and reduce the risk of all-cause mortality.
