If your heart is only working at 30 percent, it indicates a significantly reduced ejection fraction (EF), suggesting relatively severe heart failure.
Understanding Ejection Fraction (EF)
Ejection fraction is a measurement of how well your heart pumps blood with each beat. It's the percentage of blood pumped out of the left ventricle (the heart's main pumping chamber) with each contraction. A normal EF is typically between 55% and 70%.
Implications of a 30% Ejection Fraction
According to the reference, when the EF falls below 30%, it signifies a worsening condition of heart failure, indicating a more severe state. An EF of 20% or below is considered very severe.
Severity Levels
| Ejection Fraction (EF) | Severity Level |
|---|---|
| 55% - 70% | Normal |
| Below 30% | Relatively Severe |
| 20% or Below | Very Severe |
Important Considerations
- It's essential to know that the correlation between symptoms and the EF is not always perfect. Some individuals may experience severe symptoms even with a slightly higher EF, while others might have fewer symptoms despite a low EF.
