Hearts: They are very different to physicians and to the physiology of specific heart diseases and how they are treated. Heart failure is a failure of the pump mechanism of the heart to effectively pump oxygenated blood to the body and bring it back. There can be many causes of this problem. Heart attack represents an acute blockage of oxygen flow to some specific muscular area of the heart.

Difference....: They are different. A heart attack is when a blockage occurs in one (or more) of the blood vessels that supplies blood to the heart muscle. Heart failure is when the heart is not able to pump adequate blood to the bodily organs. A stroke (not heart stroke) occurs when there is a blockage of one of the blood vessels supplying the brain or when a blood vessel in the brain leaks.
