Statins block an enzyme the body needs
cholesterol. As a result,
LDL ("bad") cholesterol levels in the blood go down,
thereby lowering total blood cholesterol levels.
Statins help reduce the risk of heart attack and stroke. Along with reducing cholesterol levels in the blood, statins reduce inflammation around the cholesterol buildup (called a plaque). By stabilizing the plaque, there is less risk that it will rupture and cause a blood clot that can lead to a heart attack or stroke.
Statins are used to lower cholesterol and risk for heart attack and stroke.
Statins lower the levels of LDL cholesterol and triglycerides. Statins lower the risk of a heart attack and stroke in people who have heart disease or peripheral arterial disease, had a heart attack, or had a stroke. Statins can also lower risk in people who have risk factors such as high LDL cholesterol, low HDL cholesterol, high blood pressure, or diabetes.1
