A blood clot is a pile of blood cells in a vein or artery in your body that blocks the vein or artery. Can be caused by several things including plaque due to high cholesterol. If a piece breaks off and gets to the brain it can cause a stroke. In the heart. A heart attack. Remember I said CAN. not WILL CAUSE.
