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 ...
Nearly one of every four people (24.7%) hospitalized in the U.S. with congestive heart failure is readmitted within 30 days. [145] 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.
Symptoms usually include one or more of the following: orthopnea (difficulty breathing while lying flat), dyspnea (shortness of breath) on exertion, pitting edema (swelling), cough, frequent night-time urination, excessive weight gain during the last month of pregnancy (1-2+ kg/week; two to four or more pounds per week), palpitations (sensation of racing heart-rate, skipping beats, long pauses ...
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. [2]
A transthoracic echocardiogram (TTE) is the most common type of echocardiogram, which is a still or moving image of the internal parts of the heart using ultrasound.In this case, the probe (or ultrasonic transducer) is placed on the chest or abdomen of the subject to get various views of the heart.
Dapagliflozin is used along with diet, exercise, and usually with other glucose-lowering medications, to improve glycaemic control in adults with type 2 diabetes. . Dapagliflozin, in addition to other SGLT2-inhibitors, was shown to reduce the rate of decline in kidney function and kidney failure in non-diabetic and type 2 diabetic adults when added to the existing treatment
When employees cannot perform their work within standard times, performance can suffer. Effective training can increase performance by improving the skills that directly impact the quality of output. A skilled operator knows how to measure work, understands the impacts of variability, and knows to stop production for corrective actions when ...
