Older adults without heart disease shouldn’t take daily low-dose aspirin to prevent a first heart attack or stroke, an influential health guidelines group said in preliminary updated advice released last month.

Bleeding risks for adults in their 60s and up who haven’t had a heart attack or stroke outweigh any potential benefits from aspirin, the U.S. Preventive Services Task Force said in its draft guidance.

For the first time, the panel said there may be a small benefit for adults in their 40s who have no bleeding risks. For those in their 50s, the panel softened advice and said evidence of benefit is less clear.

The recommendations are meant for people with high blood pressure, high cholesterol, obesity or other conditions that increase their chances for a heart attack or stroke.

Regardless of age, adults should talk with their doctors about stopping or starting aspirin to make sure it’s the right choice for them, said task force member Dr. John Wong, a primary-care expert at Tufts Medical Center.

“Aspirin use can cause serious harms, and risk increases with age,” he said. Newer studies and a re-analysis of older research prompted the updated advice, Wong said.

If finalized, the advice for older adults would backtrack on recommendations the panel issued in 2016 for helping prevent a first heart attack and stroke, but it would be in line with more recent guidelines from other medical groups.

Doctors have long recommended daily low-dose aspirin for many patients who already have had a heart attack or stroke. The task force guidance does not change that advice.

Aspirin is best known as a pain reliever but it is also a blood thinner that can reduce chances for blood clots. But aspirin also has risks, even at low doses — mainly bleeding in the digestive tract or ulcers, both of which can be life-threatening.

The guidance was posted online to allow for public comments until Nov. 8. The group will evaluate that input and then make a final decision.
