Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently.
Congestive heart failure (CHF) is a clinical syndrome in which the heart fails to pump blood at the rate required by the metabolizing tissues or in which the heart can do so only with an elevation in filling pressure.Signs of CHF are demonstrated in the image below.Chest radiograph shows signs of congestive heart failure (CHF). The heart's inability to pump a sufficient amount of blood to meet the needs of the body's tissues may be a result of insufficient or defective cardiac filling and/or impaired contraction and emptying.igns of CHF are demonstrated in the image below.
