What does a heart pumping at 50-55 percent indicate?

A heart pumping at 50-55 percent typically refers to the ejection fraction (EF), which measures the percentage of blood that the heart pumps out with each contraction. An EF in this range can indicate reduced heart function and may be a sign of heart failure or other cardiovascular issues. It's important for individuals with this EF to consult a healthcare provider for further evaluation and management.
