The state of the heart when it is not able to pump blood effectively to meet the requirements of the body is known as heart failure. Another term used to describe heart failure is congestive heart failure as congestion of the lungs is one of the main symptom of this disease. Heart failure is not the same as heart attack or cardiac arrest. Cardiac arrest is the term used when the heart stops beating where as heart attack denotes damage to heart muscles due to inadequate blood supply.
