How good are statins?

Answer 1

When there are high levels of cholesterol in the blood stream, it can collect within the blood vessels causing them to become narrowed or blocked. This is bad enough when in a peripheral artery, but can be lethal if it occurs in the coronary arteries. These are the vessels that provide the blood supply to heart muscle. If they become narrowed, blood struggles to get to the tissue meaning the oxygen level in the tissue becomes depleted and it is at risk of dying. If the coronary arteries become completely blocked the chance of suffering from a heart attack is very high. By helping the blood cholesterol to drop the arteries are not only more protected from becoming more blocked, but may in fact force the cells to take their cholesterol from existing supplies and reduce any existing blockages; this can help reduce the damage that has already occurred.
