Cardiology: Ejection fraction is the percentage of blood in the left ventricle that is removed with each contraction. 65% is considered normal. 25 is a low number and implies a weakness of the left ventricle that is usually referred to as a cardiomyopathy. Dilated cardiomyopathy is when the wall thins out and the ventricle gets large like a thin ballon. It can be caused by many conditions.

Abnormal: Due to the valve disorder, the heart has overworked, strained and dilated-thickened and expanded. The normal ef is 55-65%, so 25% is damaged but livable if the cause is correctable.
