Cholesterol: what good care looks like

What high cholesterol is, in plain language

Cholesterol is a fatty substance your body needs to build cells and hormones, carried through the blood by particles called lipoproteins. LDL ("bad" cholesterol) deposits cholesterol into artery walls, where it builds up as plaque over years; HDL ("good" cholesterol) helps carry cholesterol away. Triglycerides are a different type of blood fat, and very high levels raise the risk of pancreatitis.

High LDL usually causes no symptoms. The danger is silent: plaque narrows and stiffens arteries, and a plaque can rupture suddenly and trigger a heart attack or stroke. Lowering LDL, especially over many years, reduces that risk substantially, which is why cholesterol is treated even though it does not make you feel sick.

What the current guidelines recommend

The main guideline is the 2026 ACC/AHA Multisociety Guideline on the Management of Dyslipidemia (March 2026), which replaced the 2018 cholesterol guideline. Key points: LDL goals of under 55, 70, or 100 mg/dL by risk; the PREVENT risk calculator; Lp(a) measured once in a lifetime; calcium scoring for borderline risk; ezetimibe, bempedoic acid, or a PCSK9 inhibitor added sooner when a statin alone is not enough; no supplements or fish oil pills for cholesterol.

The treatments, and why each one is recommended

Statins (atorvastatin, rosuvastatin, and others) are the foundation of treatment for almost everyone who needs medicine. They lower LDL by 30 to 55 percent depending on the dose, and decades of trials show they reduce heart attacks, strokes, and cardiovascular death. Muscle aches are the most talked-about side effect, but true statin intolerance is uncommon, and a different statin or dose can usually be found.

Ezetimibe is added when a statin alone does not reach the LDL goal; it blocks cholesterol absorption in the gut and adds another 15 to 20 percent LDL lowering with minimal side effects.

PCSK9 inhibitors (alirocumab, evolocumab), given as an injection every two to four weeks, and inclisiran, given twice a year, lower LDL by 50 percent or more and are used for people at very high risk who are not at goal on oral therapy, or who cannot tolerate a statin.

Bempedoic acid is an oral, non-statin option for people who cannot tolerate statins, lowering LDL by about 15 to 25 percent.

For high triglycerides, icosapent ethyl (a purified, prescription fish oil, not an over-the-counter supplement) has been shown to reduce cardiovascular events in people with elevated triglycerides who are already on a statin.

What guideline-based care looks like at a visit

A good clinician orders a lipid panel, calculates your 10-year cardiovascular risk (the guideline now uses the AHA PREVENT calculator), and sets an LDL goal based on that risk rather than treating a single number the same way for everyone. Lipoprotein(a), or Lp(a), should be checked at least once in your life, since a high level raises risk independent of LDL and does not change much over time. A coronary artery calcium scan may be offered when your risk level is borderline, to help decide how aggressively to treat.

After starting or changing a medicine, expect a follow-up lipid panel in 4 to 12 weeks to check whether you are at goal, then rechecks every 3 to 12 months once stable.

Why choosing a guideline-based clinician matters

Large trial meta-analyses show that for every 39 mg/dL reduction in LDL cholesterol, the risk of a major cardiovascular event (heart attack, stroke, or cardiovascular death) drops by roughly a quarter, and the benefit grows the longer treatment continues. Statins remain the best-studied and most effective tool for this, which is why a clinician who avoids proven medicine in favor of supplements or unproven "cleanses" is working against evidence that has been confirmed in millions of patients.

Questions to ask your doctor

1. Which guideline do you follow for high cholesterol, and what year is it from?
2. Which of the recommended treatments am I on, and if not, why not?
3. What targets are we aiming for, and how will we track them?
4. What should make me call you before my next visit?
5. Do you sell any supplements or compounded medicines? (A guideline-based clinic does not.)
