What is ‘normal’ left ventricular ejection fraction?

Heart, 2020
Abstract Despite the recent availability of complete genome sequences of tumors from thousands of patients, isolating disease-causing (driver) non-coding mutations from the plethora of somatic variants is notoriously challenging, and only a handful of validated examples exist.

Left Ventricular Size and Ejection Fraction

Heart Failure Clinics, 2019
Despite the rapid development of emerging imaging technologies, left ventricular ejection fraction represents the cornerstone of diagnosis, choice of treatment, and prognosis in heart failure. However, true myocardial function often remains underestimated or overestimated in different conditions underlying this heterogeneous syndrome.

Effect of propafenone on left ventricular ejection fraction

The American Journal of Cardiology, 1984
The effects of orally administered propafenone on ejection fraction (EF) determined by radionuclide angiography were studied in 2 groups of patients receiving different dosing regimens. Fourteen group A patients had no clinical evidence of left ventricular (LV) dysfunction and were not receiving digoxin therapy. In this group a mean daily dosage of 879

Effect of flecainide on left ventricular ejection fraction

European Heart Journal, 1987
Antiarrhythmic agents may depress cardiac contractility and worsen heart failure. Flecainide is an effective antiarrhythmic drug, but when administered orally in patients with left ventricular (LV) dysfunction, its effect on LV function is unknown. To assess the effects of flecainide on cardiac function, LV ejection fraction (LVEF) was measured by ...

Cardiac imaging—Diminished resting left ventricular ejection fraction

Seminars in Nuclear Medicine, 1983
A 55-year-old man with a history of rheumatic heart disease and aortic valve replacement was admitted with shortness of breath. Physical examination revealed signs of congestive heart failure. A chest x-ray showed cardiomegaly with vascular congestion.

Comparison of Left Ventricular Ejection Fraction Calculation Methods

Echocardiography, 1998
Left ventricular ejection fraction (LVEF) has been used for many years to assess left ventricular systolic function. Over time, patients may have LVEF measurements performed with the use of different imaging modalities. It is important for the clinician to appreciate how these different methods compare with each other.

Cine MR determination of left ventricular ejection fraction

American Journal of Roentgenology, 1987
Cine MR imaging provides tomographic images of the heart with both high spatial and high temporal resolution. As many as 32 images per cardiac cycle can be acquired with up to four separate anatomic slices and a total imaging time of 128 cardiac cycles.

Statins and Left Ventricular Ejection Fraction Following Doxorubicin Treatment

NEJM Evidence, 2022
Statins taken for cardiovascular indications by patients with breast cancer and lymphoma during doxorubicin treatment may attenuate left ventricular ejection fraction (LVEF) decline, but the effect of statins on LVEF among patients with no cardiovascular indications is unknown.A double-blind, placebo-controlled, 24-month randomized trial of 40 mg of ...

Development of a depressed left ventricular ejection fraction in patients with left ventricular hypertrophy and a normal ejection fraction

The American Journal of Cardiology, 2004
The progression from concentric left ventricular (LV) hypertrophy to heart failure has not been well defined. Of 159 predominantly hypertensive African-American patients with LV hypertrophy and a normal ejection fraction (EF), 28 (18%) developed a reduced EF after a median follow-up of approximately 4 years.
