Heart Attack
Also known as myocardial infarction, a heart attack happens when the blood vessles that service the heart become blocked. With no blood flowing to the cells around those arteries, the cells die causing portions of the heart muscle to die as well. Once these cells are lost, they are not replaced, therefore causing permanent damage. Current research indicates that it may be possible to regrow the "damaged heart cells, heart tissue, valves and establish new blood supply to them." They would do this with the help of stem cells. Stem cells are the cells from which all other cells originate. They have the potential to develop into many different types of cells. These cells could be designed to develop into myocardial cells. They could then be used to replace the damaged heart tissue.

Famous quotes containing the words heart and/or attack:
“They borrow words for thoughts they cannot feel,
That with a seeming heart their tongue may speak;
And in their show of life more dead they live
Than those that to the earth with many tears they give.”
—Jones Very (1831–1880)
“Scandal is an importunate wasp, against which we must make no movement unless we are quite sure that we can kill it; otherwise it will return to the attack more furious than ever.”
—Sébastien-Roch Nicolas De Chamfort (1741–1794)
