If you are unsure whether you should take low-dose aspirin to reduce the risk of a heart attack (and possibly colorectal cancer), a free, easy-to-use smartphone app called the Aspirin Guide can help you and your doctor decide. You can also use it online.
Developed by Harvard researchers, it is based on 2016 guidelines from the influential U.S. Preventive Services Task Force, which assess the appropriateness of aspirin therapy based on your 10-year risk of cardiovascular disease and your risk of adverse effects from aspirin.
The app simplifies matters by incorporating the risk calculator and provides explanations that put the results into context. You need to know your medical history, blood pressure, and total and HDL (“good”) cholesterol numbers.
Consult your doctor before starting aspirin therapy.
