WASHINGTON
Harvard researchers reported Monday that millions of people consuming aspirin to prevent a heart attack may need to reconsider their habit.
People who have already suffered a heart attack or a cardiovascular episode, as well as those who have been diagnosed with heart disease, are advised to recommend a low dose of aspirin daily.
But for healthy people, this recommendation could have adverse effects. This year, guidelines have been published that exclude the usual use of aspirin in many older people without heart disease and point out that it is only for some younger people and for medical orders.
How many people need to receive the message?
In the United States, some 29 million people aged at least 40 years have consumed an aspirin daily in 2017 despite the absence of heart disease, the latest available data, according to a study conducted jointly by Harvard and the center. Doctor
Beth Israel Deaconess. About 6.6 million of these people did so without a referral from a doctor.
And nearly half of people aged at least 70 years old and not suffering from heart disease, or about 10 million people, consume aspirin daily as a preventative, reported researchers in Annals of Internal Medicine.
"This confuses many patients," said Dr. Colin O. Brien, senior resident in internal medicine at Beth Israel, who led the report.
After all, doctors have been urging patients for years to use the anticoagulant qualities of aspirin to reduce the risk of a first heart attack. But last year, three surprising new studies were published that challenged this hypothesis. These reports are among the most exhaustive and profound for testing the effects of aspirin in people with low or moderate risk of having a heart attack and have shown only marginal benefits, if at all. whether, especially among the elderly. However, aspirin users have had a clear increase in digestive tract bleeding and other side effects.
In March, these findings changed the guidelines of the American Heart Association and the American College of Cardiology:
People over the age of 70 who do not have heart disease or who are younger but who have a higher risk of bleeding should stop taking daily aspirin.
Only some people aged 40 to 70 who are not already suffering from heart disease are at a high enough risk to deserve between 75 and 100 milligrams of aspirin a day, if a doctor so decides.
Nothing has changed for survivors of heart attacks: aspirin consumption is always recommended.
But there is no way to know how many healthy people have been informed of the new recommendations.
"We anticipate that more GPs will discuss the use of aspirin with their patients and more patients to talk to their doctor," said O & # 39; Brien.
