2. Heart failure with reduced ejection fraction - Wikipedia

   This is defined as a left ventricular ejection fraction (LVEF) of 40% or less. About half of heart failure patients have a reduced ejection fraction. [2] Other types of heart failure are heart failure with mildly reduced ejection fraction (LVEF between 40% and 50%) and heart failure with preserved ejection fraction (LVEF 50% or higher). [1] [3]

   Heart failure with recovered ejection fraction (HFrecovEF or HFrecEF): patients previously with HFrEF with complete normalization of left ventricular ejection (≥50%). [64] [65] Heart failure may also be classified as acute or chronic. Chronic heart failure is a long-term condition, usually kept stable by the treatment of symptoms.

   This reduction in ejection fraction is considered heart failure. [2] Heart failure patients are generally considered if in New York Heart Association (NYHA) class II or III heart failure. Current National Institute for Health and Care Excellence (NICE) guidelines state that CRT-D device placement is inappropriate for class IV heart failure, but ...

   In simplest terms, heart failure, or congestive heart failure, occurs when the heart can’t pump enough blood to meet the body’s needs. There are four stages of heart failure. People in this ...

   Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.

   Heart failure is categorized by a measurement known as ejection fraction. Ejection fraction is the amount of blood that the left ventricle of your heart pumps out each time it contracts.
