Aspirin is a commonly used medication for pain relief and as a blood thinner. However, the use of aspirin as a daily preventative measure for heart disease is a controversial topic. According to the Mayo Clinic[2], aspirin therapy may be recommended for individuals who have had a heart attack, stroke, or have a high risk of developing heart disease. However, the American College of Cardiology and the American Heart Association recommend that people over the age of 70 should not start taking aspirin daily as a preventative measure. This is because the risk of bleeding increases with age and the benefits of aspirin may not outweigh the risks in older adults[3]. It is important to consult with a healthcare provider before starting a daily aspirin regimen, as they can assess individual risk factors and determine if aspirin therapy is appropriate. Additionally, it is important to follow the recommended dosage and not exceed the recommended daily amount.
