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:
“Vanity is so anchored in the heart of man that a soldier, a soldier’s servant, a cook, a porter brags and wishes to have his admirers. Even philosophers wish for them. Those who write against vanity want to have the glory of having written well; and those who read it desire the glory of having read it. I who write this have perhaps this desire, and perhaps those who will read it.”
—Blaise Pascal (1623–1662)
“Hence that general is skilful in attack whose opponent does not know what to defend; and he is skilful in defense whose opponent does not know what to attack.”
—Sun Tzu (6th–5th century B.C.)
