People with extremely high levels of cholesterol are at risk of getting heart attacks. Cholesterol is a cheesy substance that coats the inner lining of blood vessels. The body needs cholesterol to build healthy cells, but high levels are harmful.
With long-standing high levels of cholesterol, that fatty particle streak into the lining of blood vessels makes them stiff unable to allow enough blood to flow through. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.
