what are statins for

Statins are medicines used to lower “bad” LDL cholesterol and reduce the risk of heart attack and stroke, especially in people at higher cardiovascular risk. They are usually taken long term as part of an overall heart‑health plan that also includes lifestyle changes like diet, exercise, and not smoking.

What statins are for

• Lower LDL (“bad”) cholesterol and often triglycerides in the blood.

• Reduce the chance of heart attack, stroke, and other problems caused by clogged arteries (atherosclerosis).

• Help both people who already have heart or blood vessel disease (secondary prevention) and those at high risk who have not yet had an event (primary prevention).

Who usually gets statins

Doctors typically consider statins for people who:

• Have known heart disease, prior heart attack, angina, or stroke.
• Have very high LDL cholesterol (for example, familial hypercholesterolemia).
• Have diabetes plus other risk factors, usually between ages 40–75.
• Have an estimated 10‑year risk of heart attack or stroke above certain guideline cut‑offs.

The exact decision is individualized, weighing benefits and risks in a discussion with a clinician.

How statins work

• Block HMG‑CoA reductase, a liver enzyme needed to make cholesterol, so the liver pulls more LDL out of the blood.

• Lower LDL levels and can modestly raise HDL (“good”) cholesterol.

• Help stabilize cholesterol plaques in arteries, making them less likely to rupture and cause a heart attack.

Common examples

• Atorvastatin, rosuvastatin, simvastatin, pravastatin, lovastatin, fluvastatin, pitavastatin.

• Dose and specific drug depend on cholesterol levels, other medicines, kidney/liver function, and overall risk.

Benefits and risks in brief

Potential benefits:

• Lower LDL cholesterol, often by 30–50% or more depending on dose and drug.

• Modest absolute reductions in risk of heart attack, stroke, and death from cardiovascular causes over years of use.

Potential risks/side effects (usually mild but important):

• Muscle aches or weakness; very rarely, serious muscle injury.

• Small increase in risk of developing diabetes in some people.

• Occasional liver‑enzyme changes, usually monitored with blood tests when indicated.

If you are taking or considering a statin, it is essential to review your personal risk factors, other medications, pregnancy plans, and any side effects with a healthcare professional before starting, stopping, or changing the dose.
