New heart guidelines are urging Americans to take cholesterol more seriously earlier in life, with doctors now recommending screening and possible treatment starting in their 30s.
The updated guidance from the American College of Cardiology and the American Heart Association marks a shift in how doctors evaluate heart disease risk. Instead of focusing mainly on a 10-year window, doctors are now encouraged to look at a person’s 30-year risk.
Under the new recommendations, adults as young as 30 with LDL cholesterol levels of 160 or higher may be considered for statins, especially if they also have risk factors such as family history, high blood pressure, diabetes, or smoking.
Statins are widely used medications that lower LDL, often called “bad” cholesterol. Over time, high LDL can build up in the arteries and lead to heart attacks or strokes.
“The time-averaged value of your LDL cholesterol over your lifetime is one of the strongest predictors of whether you’re going to have a heart-related event,” said Dr. Steven Nissen of the Cleveland Clinic. “It’s really about reducing lifelong risk, not 10-year risk.”
The guidelines also set clearer cholesterol targets. For most people, LDL should be below 100. For higher-risk patients, the goal is below 70, and for those who already have heart disease, below 55.
Doctors are advised to use a newer tool called the PREVENT calculator, which estimates both 10-year and 30-year cardiovascular risk using factors such as body weight, cholesterol levels, and smoking status.
The guidelines also recommend at least one lipoprotein(a), or Lp(a), test in adulthood. This inherited risk factor does not show up on standard cholesterol tests.
Heart disease remains the leading cause of death in the United States, with one person dying every 34 seconds. About one in four adults has high LDL cholesterol.
Doctors say lifestyle changes still come first, including diet, exercise, blood pressure control, blood sugar control, and avoiding tobacco.
“We always want to try to improve lifestyle habits at each and every visit, but sometimes medication can be very helpful if lifestyle doesn’t do the trick,” said Dr. Roger Blumenthal of Johns Hopkins.
Gigi Gari Campos, 37, said she knew for years that she faced a higher risk because of a genetic condition that raises cholesterol levels, but treatment was delayed.
“If there was medical consensus, and every single doctor I saw would have said, ‘We know you need to start now or as soon as possible,’ then it would have been a very different journey for me,” Campos said.
She had a heart attack at 34.
“I was on a two-mile walk with my husband. It was a beautiful, ordinary day,” she said. “I felt that I had some chest pressure.”
Campos later went into cardiac arrest but survived. She now takes medication and has lowered her cholesterol to healthy levels.
“The most important thing is to educate yourself and know that whatever treatment options you choose, if you don’t hit those lower levels, you are increasing your chance of ending up with a heart event,” she said.
“If you wait until people get to 55 or 60, a lot of the damage has already been done,” Nissen said.
The new guidelines reflect a broader shift toward prevention, with doctors aiming to address
heart disease risk decades before it becomes life-threatening.
