Healthy people taking a daily dose of aspirin to prevent heart attacks may be doing themselves more harm than good, according to a new study by British scientists.
Researchers found that the risks of bleeding from taking aspirin were such that its routine use in healthy people "cannot be supported" -- although they did not dispute its use in patients with a history of vascular problems.
The results of the Aspirin for Asymptomatic Atherosclerosis (AAA) study add to a long-running debate about whether the potential dangers of taking aspirin could outweigh the benefits from reducing the risk of clots.
"We know that patients with symptoms of artery disease, such as angina, heart attack or stroke, can reduce their risk of further problems by taking a small dose of aspirin each day," said Professor Peter Weissberg, medical director of the British Heart Foundation which helped fund the research.
"The findings of this study agree with our current advice that people who do not have symptomatic or diagnosed artery or heart disease should not take aspirin, because the risks of bleeding may outweigh the benefits."
The study was led by Professor Gerry Fowkes from the Wolfson Unit for Prevention of Peripheral Vascular Diseases in Edinburgh, Scotland, and presented at the European Society of Cardiology Congress in Barcelona yesterday.
