Heart Failure with Reduced Ejection Fraction (HFrEF)
Heart failure with reduced ejection fraction (HFrEF) is a condition where the heart muscle becomes weakened and cannot pump blood efficiently. This results in a decreased ejection fraction (EF), typically defined as an EF of ≤40%. Understanding Ejection Fraction (EF) Ejection fraction is a measurement of the percentage of blood the left ventricle pumps out
