New Guidelines Call for Earlier Cholesterol Screening

Doctors should begin checking and treating high cholesterol earlier in adulthood, according to new guidance from the American Heart Association and other medical groups.

The updated recommendations encourage physicians to pay closer attention to cholesterol risk in adults as young as 30. The goal is to spot problems sooner, especially high LDL cholesterol, often called “bad” cholesterol, before it has decades to damage the heart and blood vessels.

High cholesterol is a major risk factor for heart disease and stroke. LDL cholesterol can build up inside arteries, forming plaque that narrows the space where blood flows. Over time, that buildup can raise the risk of heart attack, stroke, and other serious cardiovascular problems.

The new guidance urges doctors to use a tool called PREVENT to estimate a person’s 10-year risk of heart disease. The tool is designed for adults ages 30 to 59 and helps doctors look beyond a single cholesterol number. It can include several risk factors, giving patients and providers a clearer picture of long-term heart health.

The message is simple: do not wait until middle age or later to think about cholesterol. Many people can have high LDL cholesterol without symptoms. That means a person may feel healthy while plaque is slowly building in the arteries.

Earlier screening gives patients more time to act. For some people, lifestyle changes may be enough to lower risk. These can include eating more fruits, vegetables, whole grains, beans, nuts, and lean proteins; cutting back on saturated fats; exercising regularly; avoiding tobacco; and maintaining a healthy weight.

For others, medication may be needed. Cholesterol-lowering drugs can reduce LDL levels and help lower the risk of heart attack and stroke, especially for people with a higher risk or a family history of early heart disease.

The updated recommendations are also a reminder for younger adults to know their numbers. Blood pressure, cholesterol, blood sugar, family history, smoking status, and weight can all help shape a person’s heart risk.

Heart disease often develops slowly, over many years. That is why earlier action matters. Finding and treating high cholesterol in a person’s 30s or 40s may help prevent serious problems in their 50s, 60s, and beyond.

The takeaway is clear: cholesterol screening is not just for older adults. Asking your doctor when to be tested,  and what your LDL number means, can be an important step toward protecting your heart for the long run.
