US cholesterol guidelines: Why 21.5 million more Americans may now qualify for statins as doctors shift to lifetime heart disease risk

More than half of adults between the ages of 30 and 79, about 87.5 million people, in the United States now fulfill the criteria to take cholesterol-lowering drugs called statins to prevent future heart attacks, strokes and other issues, according to a study by University of Pittsburgh School of Medicine researchers. An additional 21.5 million Americans are now recommended for statins, bringing the total to just under 57% of adults ages 30 to 79, according to the new paper by a team from the University of Pittsburgh and the University of Michigan.

“The shift to a longer view of cardiovascular disease risk is a sea change for doctors in counseling patients,” said Timothy S. Anderson, M.D., M.A.S., a primary care physician, health quality researcher and assistant professor of medicine at Pitt.

“We wanted to better understand the potential population-health effect of this shift.”

He added, “Before the new guidelines, people who were flagged with high cholesterol in their 30s and 40s tended to be recommended to focus on diet and exercise and were not recommended medication, unless the patient already had heart disease or other factors that made them particularly high risk, like diabetes.”

US cholesterol guidelines statins: What it means?

Instead of looking only at your risk of having a heart attack over the next 10 years, the new guidelines ask doctors to consider your risk over your entire lifetime or the next 30 years. This means many more people—especially younger adults who think they're healthy—may now qualify for statins, even if their cholesterol or other test results were previously considered normal.

Jeremy Sussman, M.D., M.Sc., the study’s senior author and a primary care physician at the VA Ann Arbor Healthcare System who is an associate professor in internal medicine at the U-M Medical School, notes that risks, and therefore statin eligibility under any guideline, rise with age.

“Under the new guidelines, about 10% of Americans in their 30s and 40% in their 40s are recommended statins. By the time people are in their 50s, however, that number goes up to around 80%, and for people in their 60s, it's 85%. And over 90% of all people in their 70s are recommended statins under today’s guidelines.”

Sussman also stressed that it’s important for patients to talk with their physician or other prescriber about their eligibility for statins and any concerns they might have.

“Statins have been in use for well over 40 years in America, many are very inexpensive, and they have been proven generally very safe and very effective,” he said.

“There are some side effects possible, but they're not that severe and not as common as we expect them to be.”

What's new in the statin guidelines?

New guidelines from the American Heart Association (AHA), American College of Cardiology (ACC) and other medical groups could make 21.5 million more Americans eligible for statins, according to an analysis published in JAMA. That would bring the total number of eligible adults aged 30 to 79 to about 87.5 million.

Heart risk will now be measured differently

Instead of looking only at your risk over the next 10 years, doctors are now encouraged to assess your 30-year or lifetime risk using the PREVENT calculator, which can be used from age 30. The aim is to identify people who may develop heart disease later in life, even if they seem healthy today.

Lower cholesterol targets

The new guidance also recommends lower LDL ("bad") cholesterol goals:

Below 100 mg/dL for most adults without heart disease
Below 70 mg/dL for people at higher risk
Even lower targets may be recommended for those at the highest risk
Does this mean everyone will need statins?

No. Being eligible doesn't automatically mean you'll be prescribed a statin. Doctors will also consider your blood pressure, diabetes, smoking history, kidney health, family history and overall heart disease risk before making a decision.

Healthy habits still matter

Experts say statins should complement—not replace—a healthy lifestyle. Eating a balanced diet, exercising regularly, maintaining a healthy weight and avoiding smoking remain the best ways to lower your risk of heart disease.

Are statins safe?

Most people take statins without major problems. Some may experience muscle pain, tiredness or mild stomach issues. Rarely, statins can affect liver enzymes or slightly increase the risk of type 2 diabetes, but studies show they can significantly reduce the risk of heart attacks and strokes in people who need them.
