Lakkireddy acknowledged that currently left ventricular ejection fraction is the primary surrogate marker cardiologists rely on to identify post-MI patients who are at increased risk for ventricular arrhythmia.
His echocardiogram showed a very poor bi-ventricular function with a left ventricular ejection fraction of 20% and right ventricular ejection fraction of 30%.
A Left ventricular ejection fraction (LVEF) is the percentage of blood pumped out of the heart's main pumping chamber during each contraction.
We presented the case of a patient who developed heart failure secondary to right ventricular pacing, with a severely decreased left ventricular ejection fraction (from 60 to 30% in four months) and severe mitral regurgitation.
They examined 4,255 participants, conducted Cardiac magnetic resonance imaging to measure left ventricular volume (structure), and left ventricular ejection fraction (function), Medical Daily reported.
cTnT is uniquely located in the myocardium and its release closely relates to infarct size; therefore, inversely correlates with left ventricular ejection fraction (LVEF).
In a meta-analysis of beta blocker trials, patients with heart failure (HF) and reduced left ventricular ejection fraction (LVEF) who took beta blockers (e.g., Propranolol, Metoprolol) showed reduced risk of HF-related mortality and hospitalizations.
The patient was able to return to normal life two weeks after the AMIRST procedure, and the main findings of the study showed a significant improvement in the left ventricular ejection fraction (LVEF) from 35 percent at patient's initial assessment to 60.3 percent at 24 months post-AMIRST intervention.
Witte and colleagues found significant evidence of improved function and a reversal of left ventricular remodeling as measured by left; ventricular ejection fraction +6.07% (95% confidence interval, 3.20-8.95; P less than .0001); left ventricular end diastolic diameter -2.49 mm (95% Cl, -4.09 to -0.90; P = .002); and left ventricular end systolic diameter -2.09 mm (95% Cl, -4.11 to-0.06; P= .043).
The left ventricular ejection fraction data were collected from 2-dimensional echocardiogram.
Planar radionuclide ventriculography (RVG) also commonly known as multigated acquisition (MUGA) cardiac blood pool scintigraphy has long been a simple and noninvasive method to assess ventricular function and, in particular, left ventricular ejection fraction (LVEF).
