A stroke is a brain attack, it occurs when the blood supply to part of the brain is cut off. Blood carries essential nutrients and oxygen to the brain. Without a blood supply, brain cells can be damaged or destroyed and won't be able to do their job. (Stroke Association)
An acute myocardial infarction or heart attack occurs when an area of the heart muscle dies or is damaged due to an inadequate supply of oxygen. A blood clot forms in one of the coronary arteries, the blood vessels that supply blood to the heart. This clot prevents blood, and consequently, oxygen from reaching the heart cells in that area, leading to their death.
