Cholesterol is a waxy substance that comes from two sources: your body and food. Excess cholesterol can form plaque between layers of artery walls, making it harder for your heart to circulate blood.
Plaque can break open and cause blood clots. If a clot blocks an artery that feeds the brain, it causes a stroke. If it blocks an artery that feeds the heart, it causes a heart attack.
Heart disease, stroke and other cardiovascular diseases are among the leading cause of death and now kill more than 800,000 adults in the US each year. Two main reasons people have heart disease or stroke are high blood pressure and cholesterol.
