Heart failure is also known as congestive heart failure. Heart failure becomes more common with advancing age. Heart failure is a condition in which the heart can't pump enough blood through the body. Heart failure develops with time while the pumping action of the heart grows weaker.
Heart failure may derive from disorders that cause the heart's walls to stiffen, such as for example infiltrations and infections. Heart failure due to systolic dysfunction usually develops because the heart cannot contract normally. Heart failure has two main forms: systolic dysfunction (which is more common) and diastolic dysfunction.
In systolic dysfunction, the heart contracts less forcefully and cannot generate the maximum amount of the blood that's returned to it as it normally does. Heart valve disorders narrowing (stenosis) of a valve, which hinders blood flow through the heart, or leakage of blood backward (regurgitation) via a valve, could cause heart failure.

Some heart valve disorders, such as for example aortic valve stenosis, hinder blood flow out of the heart. Other causes may include diseases of the heart valves and weakened heart muscle due to viral infections or their poisonous products (called toxins).
People with heart failure are sensitive to small shifts inside their intravascular volume status (the amount of fluid inside their circulatory system). Often left heart failure leads to right heart failure and then both sides are affected.
