Aspirin lowers heart attack risk but may cause severe internal bleeding

People without heart disease who take a daily aspirin may lower their risk of a heart attack or stroke, but a new study confirms they also have an increased risk of severe internal bleeding.

US doctors have long advised adults who have not had a heart attack or stroke but are at high risk for these events to take a daily aspirin pill, an approach known as primary prevention. Even though there is clear evidence aspirin works for this purpose, many physicians and patients have been reluctant to follow the recommendations because of the risk of rare but potentially fatal internal bleeding.

For the current study, researchers examined data from 13 clinical trials testing the effects of aspirin against a placebo or no treatment in more than 164,000 adults.

"The results demonstrate that there are cardiovascular benefits, but that they are quite closely matched by increased risks of serious bleeding," said lead study author Dr Sean Zheng of King's College London and Imperial College London.
