2024年3月8日 · For the person with de novo HFrEF, therapies should be initiated with a goal of reaching target or maximally tolerated doses of the 4 key medication classes as soon as possible, and ideally no longer than 3 months.

2024年5月5日 · Heart failure (HF) is a prevalent and potentially life-threatening condition when not addressed. This article strives to delineate the various forms of heart failure, elucidating the stages, types of HF, and methods of diagnosis and treatment.

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 …

2022年4月1日 · RCTs with evidence of survival benefit in patients with HF have mainly enrolled patients with HF with an LVEF ≤35% or ≤40%, often labeled HF with reduced ejection fraction (HFrEF). 1 In this guideline, HFrEF is defined as LVEF ≤40% (Table 4).

2023年10月26日 · Heart failure with reduced ejection fraction (HFrEF) means your left heart ventricle has weakened and less blood is being pumped into your body. HFrEF requires ongoing treatment to...

2023年3月23日 · Learn about the types of heart failure, including congestive heart failure, systolic failure (HFrEF), and diastolic failure (HFpEF).

HF due to left ventricular (LV) dysfunction is categorized according to LV ejection fraction (LVEF) into HF with reduced ejection fraction (with LVEF ≤40 percent, known as HFrEF; also referred to as systolic HF), HF with preserved ejection fraction (with LVEF ≥50 percent; known as HFpEF; also referred to as diastolic HF), and HF with mid ...

Symptoms and signs of heart failure due to a reduced EF is termed HFrEF or heart failure with reduced EF. However, when a patient has similar symptoms and signs as in HFrEF, but they have a normal EF, the term HFpEF (heart failure with preserved ejection fraction) is …

Left ventricular ejection fraction (EF) remains the major parameter for diagnosis, phenotyping, prognosis and treatment decisions in heart failure. The 2016 ESC heart failure guidelines introduced a third EF category for an EF of 40–49%, defined as …

The amount of blood pumped out of the heart with each beat is called the ejection fraction (EF). A normal EF is usually around 55 to 70 percent, but it can be lessened in some forms of heart failure. 1 People with heart failure with reduced ejection fraction (HFrEF) have an EF that is 40 to 50 percent or lower.
