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 ...
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.
Angiographic LM 50%, or two or more primary vessels 70% stenosis, or isolated branch stenosis 70% in all 3 systems; or ISHLT CAV1 or CAV2 with allograft dysfunction (defined as LVEF 45% usually in the presence of regional wall motion abnormalities) or evidence of significant restrictive physiology
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]
[10] [11] [18] To investigate its use for heart failure in those with a preserved LVEF (HFpEF), Novartis funded the PARAGON-HF trial which was designed to investigate the use of sacubitril/valsartan in the treatment of HFpEF patients with a LVEF of 45% or more. Concluding in 2019, it failed to show significance for reducing hospitalisation ...
Peripartum cardiomyopathy is a heart failure caused by a decrease in left ventricular ejection fraction (LVEF) to <45% which occurs towards the end of pregnancy or a few months postpartum. Symptoms include shortness of breath in various positions and/or with exertion, fatigue, pedal edema, and chest tightness.
take (often effectively a noun meaning "prescription"—medical prescription or prescription drug) rep. repetatur: let it be repeated s. signa: write (write on the label) s.a. secundum artem: according to the art (accepted practice or best practice) SC subcutaneous "SC" can be mistaken for "SL," meaning sublingual.

The FDA approved the OPTIMIZER Smart System, which delivers cardiac contractility modulation therapy, as indicated to improve 6-minute hall walk distance, quality of life, and functional status of NYHA Class III heart failure patients who remain symptomatic despite guideline directed medical therapy, who are in normal sinus rhythm, are not indicated for cardiac resynchronization therapy, and ...
