2023年6月14日 · Ejection fraction (EF) is a measurement, expressed as a percentage, of how much blood the left ventricle pumps out with each contraction. An ejection fraction of 60 percent means that 60 percent of the total amount of blood in the left ventricle is pushed out with each heartbeat. A normal heart’s ejection fraction is between 55 and 70 percent.

2024年5月5日 · This patient education includes an explanation of diastolic heart failure, which is also called heart failure with preserved ejection fraction, or HFpEF. Heart failure symptoms and ejection fraction are discussed.

2024年2月6日 · You could have heart failure with preserved ejection fraction (HFpEF). It happens when your heart muscle thickens to the point that the left ventricle holds less than the usual amount of blood ...

2024年10月14日 · Normal EF is in the range of 55% to 70%. As the percentage falls, it tells the doctor that the heart failure is getting worse. In general, if the EF falls below 30%, it's relatively severe. A...

2021年6月1日 · Based on emerging evidence, revised nomenclature is proposed defining heart failure with “reduced” (<40%), “mildly reduced,” and “normal” (≥55% in men, ≥60% in women) ejection fraction. Such nomenclature signals consideration of potentially beneficial therapies in the largest group of patients with reduced or mildly reduced ejection fraction.

2024年3月19日 · Heart failure with preserved ejection fraction (HFpEF), previously known as diastolic heart failure, is currently defined as a left ventricular ejection fraction of ≥50% with evidence of spontaneous or provokable increased left ventricular filling pressures; HFpEF comprises at least 50% of all heart failure diagnoses.

It is also possible to have a diagnosis of heart failure with a seemingly normal (or preserved) ejection fraction of greater than or equal to 50%. With the proper care and treatment, many people are able to improve their ejection fraction and live a longer and healthier life. Talk with your health care professional about your options.

Patients with HF are frequently classified by left ventricular ejection fraction (LVEF). This classification system acknowledges the different prognoses and responses to guideline-directed medical therapy (GDMT) for patients with heart failure.

2024年3月19日 · Heart Failure with Mildly Reduced Ejection Fraction (HFmrEF): patients with an LVEF 41% to 49% with evidence of spontaneous or provokable increased left ventricular filling pressures (LVFPs), characterized by elevated natriuretic peptides or …

2024年12月11日 · Heart failure with reduced ejection fraction (HFrEF) is HF with left ventricular ejection fraction (LVEF) of 40% or less. Heart failure with mildly reduced EF (HFmrEF) is HF with LVEF 41% to 49%. HF is a major and growing public health problem.
