Myocardial infarction is the medical name for a heart attack. When the blood flow to a section of your heart muscle is blocked, the result is a heart attack. When this occurs, the blocked section is deprived of oxygen and begins to die if the normal flow of blood is not quickly restored.

The kidneys are a pair of organs located on either side of your spine, just above your waist. These organs are four to five inches long, and their function is to filter impurities from the blood, balance electrolytes in your body, and control blood pressure.
