Normal Left Ventricular Ejection Fraction (LVEF) ranges from 50% to 70%, according to the American College of Cardiology (ACC).
Understanding LVEF
LVEF, or Left Ventricular Ejection Fraction, is a measurement of how much blood the left ventricle of the heart pumps out with each contraction. It's a key indicator of heart function and is expressed as a percentage.
LVEF Classification
The American College of Cardiology (ACC) provides a simple classification for LVEF that is widely used in clinical practice:
| LVEF Classification | LVEF Range | Midpoint |
|---|---|---|
| Hyperdynamic | Greater than 70% | |
| Normal | 50% to 70% | 60% |
| Mild Dysfunction | 40% to 49% | 45% |
Practical Insights into LVEF
- Normal LVEF: An LVEF of 50% to 70% indicates that the heart is pumping blood effectively to meet the body's needs.
- Clinical Significance: LVEF is a crucial parameter in diagnosing and managing heart failure. It helps clinicians assess the severity of heart dysfunction and tailor treatment strategies accordingly.
