ASPREE: The Aspirin Study

Study Type

Healthy Aging

Study Purpose

The purpose of this research study is to determine if daily aspirin can lower your risk of developing heart disease and dementia while maintaining your high quality of life.

About the Study

Can aspirin help prevent heart disease and dementia?

Over the last few years, we have heard of the benefits of aspirin in preventing heart disease. Did you know that aspirin may also help in preventing other age-related diseases as well? In order to get a better understanding of the benefits of aspirin, the National Institutes of Health (NIH) is conducting a multi-year research study at Pennington Biomedical Research Center.

The purpose of this research study is to find out if low dose aspirin will prevent age related diseases such as heart disease, stroke, cancer, and dementia in elderly people. In addition, this study will determine if these benefits will be greater than the possible risks of taking low dose aspirin. The ASPREE study is one of the first studies looking at how aspirin can benefit healthy, independent seniors so they may continue their high quality of life.
