Heart disease is the narrowing or blockage of the arteries and vessels that provide oxygen and nutrient-rich blood to the heart. It is caused by atherosclerosis, an accumulation of fatty materials on the inner linings of arteries that restricts blood flow. When the blood flow to the heart is completely cut off, the result is a heart attack because the heart is starved of oxygen.
