Heart failure refers to the heart’s inability to pump enough blood to satisfy the needs of the body.
Heart failure, sometimes called congestive cardiac failure (CCF), is a condition in which the heart muscle is weakened and can’t pump as well as it usually does. The main pumping chambers of the heart (the ventricles) can change size and thickness, and either can’t contract (squeeze) or can’t relax (fill) as well as they should. This triggers fluid retention, particularly in the lungs, legs and abdomen
