This article provides a list of autoimmune diseases. These conditions, where the body's immune system mistakenly attacks its own cells, affect a range of organs and systems within the body. Each disorder is listed with the primary organ or body part that it affects and the associated autoantibodies that are typically found in people diagnosed ...
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.
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 ...
In summary, the diagnosis of autoimmune disorders is a complex process that requires a thorough evaluation of clinical, laboratory, and imaging data. Due to the diverse nature of these diseases, an individualized approach, often involving multiple specialists, is crucial for an accurate diagnosis.
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 ...
An autoimmune disease is a condition arising from an abnormal immune response to a normal body part. [5] There are at least 80 types of autoimmune diseases. [5] Nearly any body part can be involved. Common symptoms include low-grade fever and feeling tired. [5] Often symptoms come and go. [5]
It is a type of cardiomyopathy, a group of diseases that primarily affects the heart muscle. [3] The diagnosis may be supported by an electrocardiogram, chest X-ray, or echocardiogram. [9] In those with heart failure, treatment may include medications in the ACE inhibitor, beta blocker, and diuretic families. [9] A low salt diet may also be ...
The dilated left ventricle causes an increase in the wall stress of the cardiac chamber as well.While the ejection fraction is less in the chronic decompensated phase than in the acute phase or the chronic compensated phase, it may still be in the normal range (i.e.: > 50 percent), and may not decrease until late in the disease course.
