Cholesterol is needed by the body, but the amount and type of cholesterol in the blood matter for cardiovascular risk. LDL is one lipoprotein that carries cholesterol. Higher LDL levels can contribute to plaque buildup in artery walls over time, but a single lab number is only one part of a person’s overall risk.
What an LDL result can—and cannot—tell you
An LDL result helps a clinician assess risk alongside factors such as age, blood pressure, smoking, diabetes, family history, and prior cardiovascular disease. The right interpretation depends on the person and the clinical context. The American Heart Association’s 2026 dyslipidemia guideline summary describes current approaches to assessing and managing blood lipids.
What statins do
Statins lower LDL cholesterol and can reduce the risk of cardiovascular events for people who are likely to benefit. The expected benefit, dose, and possible side effects depend on individual health history and risk. A clinician can explain why a statin is recommended, what result to monitor, and what to do if a side effect occurs.
Questions to discuss with a clinician
- What is my LDL result, and what target or range applies to my level of risk?
- Which factors are driving my estimated heart and stroke risk?
- What benefit is expected from a statin in my case?
- Which side effects or medication interactions should I watch for?
- When should we repeat a blood test or review the treatment plan?
Lifestyle still matters
Food choices, physical activity, not smoking, and managing conditions such as high blood pressure and diabetes can support cardiovascular health. The right changes depend on a person’s circumstances; they do not always replace medication when medication is indicated. The AHA provides diet and lifestyle information for managing high cholesterol.
Do not start or stop a statin on your own
If you are concerned about side effects, interactions, or whether you still need a medication, contact the clinician who prescribed it. The National Heart, Lung, and Blood Institute advises people living with high blood cholesterol to follow their care plan and discuss concerns with their healthcare provider. See its guidance on living with high blood cholesterol. Stopping a medicine without advice may interrupt a plan intended to reduce cardiovascular risk.
