Briefly describe the following: Heart failure.
✓

Answer

Heart failure: It is the state of heart when it does not pump blood effectively enough to meet the need of the body. Congestion of lungs is one of the main symptoms of this disease. Heart failure is not the same as cardiac arrest (when the heart stops beating) or a heart attack (when the heart muscle is suddenly damaged by inadequate blood supply).
