You have probably heard that aspirin prevents heart attacks in people with coronary artery disease. It also works in healthy people without pre-existing cardiovascular problems. Research has shown that aspirin is effective in preventing first heart attacks in healthy people who have risk factors for the disease. It does this by reducing formation of blood clots that can trigger heart attacks. However, not everyone should be taking aspiring therapy. It should only be done under the guidance of your doctor.
The United States Preventive Services Task Force (USPSTF), an independent panel of medical experts, recommends aspirin therapy in the following groups:
The American Heart Association (AHA) recommends aspirin therapy for people who are considered to be at high risk of having a heart attack. A person is high risk if they have conditions such as established heart disease, peripheral artery disease, abdominal aortic aneurysm, chronic renal disease, or diabetes. People may also be at high risk they have high blood pressure, high cholesterol, or smoke. Your doctor will assess your risk. These factors are combined to assess your chance of a cardiovascular event. You may be requested to take aspirin if your combined risk is more than 10% within 10 years.
Heart disease is more common in people age 65 years or older, especially men. The risk is higher in people of African American, Mexican American, Native American, Native Hawaiian, and Asian American descent.
According to the AHA, major risk factors for heart disease include:
If you think aspirin therapy may be right for you, be sure to discuss the pros and cons with your doctor. The discussion should take into account your calculated risk for heart disease, the known protective effects of aspirin, potential side effects (such as gastrointestinal bleeding), factors that increase your risk of side effects, and your personal preferences about medical care.
