Roughly 56.6 percent of US adults ages 30 to 79 now qualify for a cholesterol-lowering statin under the 2026 dyslipidemia guideline from the American College of Cardiology and American Heart Association. That is about 87.5 million people.
The estimate comes from a JAMA analysis published on July 20, 2026, based on national health survey data from 2017 to 2023.
Led by Timothy S. Anderson at the University of Pittsburgh, the study identified 21.5 million adults as newly eligible compared with the 2018 rules. Their average 10-year heart-disease risk is only 3.1 percent, meaning most are added on the basis of long-term risk.
Eligibility climbs sharply with age. About 11 percent of adults in their 30s qualify, rising to 85 percent in their 60s and 93 percent in their 70s.

The biggest jump sits in the 50s, where 26.5 percent more adults are newly eligible than under the earlier rules, followed by a 17 percent gain in the 40s.
What actually changed
The ACC and AHA released the guideline on March 13, 2026 and extended risk assessment from adults 40 to 75 to those 30 to 79. They also replaced the older risk equations, which had overestimated 10-year heart attack and stroke risk by 40 to 50 percent.
The new rules lower the bar for a class-I statin recommendation, with 10-year risk at or above 5 percent instead of 7.5 percent.
They also add a 30-year risk track, which brings adults in their 30s and 40s into the conversation earlier, even when their short-term numbers look fine.

Roger Blumenthal, chair of the guideline writing committee, said in the AHA announcement that "lower LDL cholesterol for longer, just like lower blood pressure for longer, results in much greater protection against future heart attack and stroke risk."
What to do if your doctor has not raised it
The 2026 rules put weight on shared decision-making rather than automatic prescribing. LDL cholesterol targets sit below 100 mg/dL for borderline or intermediate risk, below 70 for high risk, and below 55 for people with established cardiovascular disease.
Adults with borderline or intermediate 10-year risk who want a clearer picture can ask about a coronary artery calcium scan, which the guideline lists as a selective tool to refine the decision.
The rules also recommend measuring lipoprotein(a), a genetically inherited particle, at least once in adulthood, since a high level flags added risk on top of LDL.

A companion analysis of NHANES data found that about 76 percent of adults who qualified for a primary-prevention statin under the earlier rules were not on any lipid-lowering therapy at all.
