By for heart attack or stroke is not recommended for adults over 70 years, according to the guidelines published on Sunday.
The recommendations, jointly issued by the American College of Cardiology and the American Heart Association, are a reversal of previous recommendations The daily intake of a baby aspirin to prevent cardiovascular problems in adults over 50 years old. The two groups agreed that the risk of gastrointestinal bleeding outweighs cardiac benefit in older low-risk adults with no history or stroke. The change comes after a large international study has found that long-term use of Aspirin can be detrimental even at low doses without providing benefit to older people who have not had a heart attack or stroke.  "Clinicians should be very selective in prescribing aspirin for people without known cardiovascular disease," Dr. Roger Blumenthal, co-chair of the ACC / AHA Directive of 2019 on the primary prevention of cardiovascular disease, in a statement. "Aspirin should be limited to people who have the highest risk of cardiovascular disease and a very low risk of bleeding."
The Committee recalled that a healthy lifestyle is the most important way to prevent the onset of atherosclerotic cardiovascular disease and heart failure and atrial fibrillation.
"The guidelines confirm what we have known for more than a decade," Dr. Steven Nissen, chair of the Department of Cardiovascular Medicine, Cleveland Clinic. "In patients without heart disease, the risks of aspirin, especially bleeding, are significant. For most patients without middle-risk heart disease, the benefits do not exceed the risks. "
Earlier this year, the AHA released a statistical update showing that nearly half of US adults have some form of cardiovascular disease. The increased risk was mainly due to hypertension.
"We follow a medical imperative of" do not harm "and aspirin is not benign," said Dr. Clyde Yancy, chief physician of cardiology at Northwestern Memorial Hospital in Chicago. "Understanding how best to take aspirin or other medicines is the kind of refinement that enables our best health."
Nearly 80 percent of all cardiovascular diseases can be prevented with lifestyle changes, Heart Association says. Doctors recommend regular physical activities and follow herbal diets such as DASH, a diet that emphasizes fruits, vegetables and whole grains to reduce heart disease risk.
