Aspirin Therapy for Preventing Heart Attack and Stroke

You may have heard about studies linking a daily dose of aspirin with a reduced risk of heart attack and stroke. Is aspirin therapy right for you?

Aspirin appears to lower the risk of blood clots that can cause a heart attack or stroke, and research has shown that people who are at high risk for cardiovascular disease can benefit from a low dose (75 to 325 mg) taken daily. Aspirin therapy seems especially helpful for those who have already had a heart attack, a stroke, or some other evidence of atherosclerotic vascular disease, or those who are at significantly increased risk because of abnormal cholesterol, high blood pressure, or diabetes.

However, for people at lower risk, the benefits of taking aspirin are less clear — and may be overshadowed by an increased risk of bleeding, a side effect of aspirin that can be quite dangerous. The risk of bleeding is also increased in those who take blood-thinning medications such as warfarin (brand name Coumadin).

The bottom line: Talk to your doctor to see whether low-dose aspirin therapy is right for you. Have the doctor assess your cholesterol level, blood pressure, and other factors to determine your heart disease and stroke risk. Don't forget to mention any other medical conditions you have and any other medications or supplements you take on a regular basis (including nonprescription products).

And remember, the other healthy lifestyle changes you are making — including eating a healthy, balanced diet rich in fiber and whole grains, avoiding unhealthy weight gain or losing weight, and getting regular exercise — also cut your risk of heart problems and stroke in the future.
