diseases and risk factors Flashcards
what are statins
Statins are a class of prescription drugs that help to lower cholesterol. Statins block the enzyme that the body uses to make cholesterol in the liver. The liver, along with other cells in the body, makes about 75 percent of the body’s cholesterol. By blocking this enzyme, the amount of cholesterol your liver makes is significantly reduced.
Give 2 advantages of statins
Most statins successfully help lower low-density lipoproteins, also known as LDL or “bad” cholesterol. Lowering your cholesterol levels with statins helps decrease your risk of stroke, heart attack, and other vessel-related diseases. For example, they help stabilize the blood vessel lining, which benefits the whole body. This also makes plaque less likely to rupture in the heart, lowering the risk of a heart attack. Statins also help to relax the blood vessels, which leads to a decrease in blood pressure.
