"Clinicians should be very selective in prescribing aspirin for people without known cardiovascular disease," according to a statement from Dr. Roger Blumenthal, co-chair of the 2019 ACC/AHA Guideline on the Primary Prevention of Cardiovascular Disease, and professor of cardiology at Johns Hopkins University in Baltimore.
"It's much more important to optimize lifestyle habits and control blood pressure and cholesterol as opposed to recommending aspirin," Blumenthal said.
Blumenthal said that "Aspirin should be limited to people at the highest risk of cardiovascular disease and a very low risk of bleeding."
The guidelines also pointed out that those who have had a heart attack or stroke could still use aspirin to prevent another cardiovascular event.
"Ultimately, we must individualize treatment for each patient, based on their individual situation," North Carolina cardiologist Dr. Kevin Campbell, told CNN.
Campbell wasn't involved in the new guidelines.
