HFrEF is defined by EF in which range?

Explanation:
HFrEF reflects reduced systolic function, shown by a low ejection fraction. This means the EF is in the lower part of the spectrum, below what is considered normal. Higher EF values indicate preserved systolic function (HFpEF), while an intermediate EF sits in the mid-range. Therefore, the range for HFrEF is the lower end of the EF spectrum.
