HFmrEF is defined by EF in which range?

Explanation:
Ejection fraction-based classification is being tested. Ejection fraction is the percentage of blood pumped out of the left ventricle with each heartbeat. Heart failure with mid-range EF is defined as an EF of 41% to 49%. This places HFmrEF between reduced EF (≤40%) and preserved EF (≥50%). The other ranges correspond to either reduced EF or higher-preserved EF, not the mid-range. So 41-49% is the standard definition for HFmrEF.
