a heart rate of 123 b.p.m., and an O2saturation of 100% on room air. Labs on admission revealed non-haemolytic anaemia with a haemoglobin level of 7.1 g/dL (normal range of 80.0–99.0 fL), which in...

Left ventricular ejection fraction (LVEF) ≤ 40% HF with preserved EF (HFpEF) or diastolic heart failure : Inadequate relaxation and filling of the ventricle but normal myocyte contractility → preserved ejection fraction despite low stroke volume LVEF ≥ 50% Heart failure with midrange EF (HFm...
Heart Left Ventricle Ejection Fraction In subject area: Medicine and Dentistry HFNEF, used as a term to describe a condition associated with HF symptoms and normal LVEF, and without obvious explanation for the symptoms (e.g., coronary artery disease, valvular heart disease), is typically associat...
Heart failure with reduced ejection fraction HNCM: Hypertrophic non-obstructive cardiomyopathy HOCM: Hypertrophic obstructive cardiomyopathy ID: Iron deficiency LA: Left atrial LAVI: Left atrial volume index LGE: Late gadolinium enhancement LV: Left ventricle/ventricular LVEDP: Left ventricular ...
Heart Left Ventricle Ejection Time In subject area: Biochemistry, Genetics and Molecular Biology The left ventricular ejection time (LVET) is defined as the time from the initial upstroke of the aortic pressure tracing to the dicrotic notch. ...
Clinical studies on heart failure with mildly reduced left ventricular ejection fraction (HFmrEF) have gradually increased. However, studies on the prognostic differences between men and women among patients with HFmrEF are few, and no evidence on sex di
coronary artery disease and structural damage to the heart. HFpEF occurs when the heart muscle contracts normally but the left ventricle does not fill with enough blood, often due to stiffening of the heart muscle. Both, HFrEF and HFpEF, are related to co-morbidities like hypertension, coronary...
One measurement ofhow much blood your heart pumps out per beat is the ejection fraction (EF). A normal EF is 50%-70%, which means that 50%-70% of the blood in your left ventricle is pumped out with each heartbeat. (It's normal for some blood to be left behind.) A reading of ...
there is incomplete mixing of the SVC and IVC blood due to the lack of the subpulmonary ventricle. As a result, the pulmonary artery is often mixed with both contrasted and non-contrasted blood with the standard protocol...
