To put it simply, heart failure is the inability of the heart to function well to meet the needs of the body. When the heart is not able to pump out enough blood it is known as heart failure with reduced ejection fraction. Ejection fraction is the fraction of the blood ejected out from the filled heart. The lower chambers of the heart fill when they relax after a contraction.
