What are the levels of ejection fraction?

What do the numbers mean?

• Ejection Fraction (EF) %: 55% to 70% Pumping Ability of the Heart: Normal.
• Ejection Fraction (EF) %: 40% to 54% Pumping Ability of the Heart: Slightly below normal.
• Ejection Fraction (EF) %: 35% to 39% Pumping Ability of the Heart: Moderately below normal.
• Ejection Fraction (EF) %: Less than 35%

How do you classify HFpEF?

HF with preserved ejection fraction (HFpEF): LVEF ≥ 50%; HF with a mid-range ejection fraction (HFmEF): LVEF 41-49%; HF with a reduced ejection fraction (HFrEF): LVEF ≤ 40%.

What is a mildly reduced ejection fraction?

A normal ejection fraction is more than 55%. This means that 55% of the total blood in the left ventricle is pumped out with each heartbeat. Heart failure with reduced ejection fraction happens when the muscle of the left ventricle is not pumping as well as normal. The ejection fraction is 40% or less.

What ejection fraction is considered severe?

Normal = LVEF 50% to 70% (midpoint 60%) Mild dysfunction = LVEF 40% to 49% (midpoint 45%) Moderate dysfunction = LVEF 30% to 39% (midpoint 35%) Severe dysfunction = LVEF less than 30%

What is the highest ejection fraction?

Typically, the left ventricle ejects 55% or more of its blood volume with each beat, so a “normal” ejection fraction is 55% (0.55) or higher.

What is an ejection fraction, and what does it mean to you?

Ejection fraction is a measurement of the percentage of blood leaving your heart each time it contracts . During each heartbeat pumping cycle, the heart contracts and relaxes. When your heart contracts, it ejects blood from the two pumping chambers (ventricles).

How is ejection fraction calculated?

Ejection fraction is calculated by the amount of blood pumped out of the heart with each beat divided by the amount of blood in the heart at its fullest. In other words, ejection fraction measures what percent of the blood in the heart is pumped out when the heart beats.

What factors affect ejection fraction values?

Since ejection fraction values deal with the pumping action of the ventricles, any condition that reduces this activity affects the values. Ineffective blood circulation to the heart or ineffective ventricle filling combined with faulty valves, weakened muscle tissue, or tissue death all contribute to the amount of blood leaving the heart.
