New Cholesterol Guidelines Lower Screening Age to 30 and Set Clearer LDL Targets

The American College of Cardiology and the American Heart Association have released updated cholesterol guidelines that lower the recommended screening age to 30. The previous standard called for screening to begin at 40.

The new guidelines also set clearer LDL cholesterol targets based on a patient's risk level. Low-risk patients should aim for LDL below 100 mg/dL. Higher-risk patients should target below 70 mg/dL. Very high-risk patients, including those with a history of heart attack or stroke, should aim for below 55 mg/dL.

The guidelines also recommend that all adults receive one-time lipoprotein(a) testing. Lipoprotein(a) is a genetic marker that raises cardiovascular risk independently of standard LDL levels. Many people with elevated lipoprotein(a) do not know it because the test is not part of routine bloodwork.

The shift toward earlier screening reflects growing evidence that cardiovascular risk begins accumulating in young adulthood. Catching elevated cholesterol at 30 rather than 40 gives patients and doctors a longer window to make lifestyle changes or start treatment before damage occurs.

Woman's World covered the guideline update as part of its 2026 health breakthroughs series, noting that the changes are especially relevant for women, who are often undertreated for cardiovascular risk compared to men.

Doctors say the new targets will require more frequent conversations about medication for patients who cannot reach their LDL goals through diet and exercise alone. Statins remain the most common treatment, and newer options like PCSK9 inhibitors are available for patients who need more aggressive management.
