Small doses of aspirin can lower the risk of heart attack in people who never had heart disease.
Researchers pooled results from nine trials that tested aspirin in the prevention of heart disease.
Nearly 100,000 men and women were involved.
The team found a 19% reduction in non-fatal heart attacks among participants who took aspirin.
They also found a small decrease in stroke and death risks with aspirin, although they admit those chances might have been due to pure chance.
The analysis revealed that aspirin increased the rate of bleeding in those taking it.
These findings making the authors conclude the drug had "uncertain value."
The study appears in the American Journal of Cardiology.
