Heart failure

Heart Failure (HF) is a serious heart condition related to its inability to pump in sufficient supply of blood to the body.

When the heart muscle doesn't pump blood as well as it should, it causes heart failure, also known as congestive heart failure. When this happens, blood can back up in the lungs and fluid can build up, causing shortness of breath.

Heart attacks and cardiac failure are both forms of heart disease, but they are not the same thing. Heart attacks occur when the heart loses blood flow, whereas heart failure occurs when the heart is unable to adequately pump blood around the body.
