Aspirin Therapy: Right for Your Heart?
Daily aspirin helps many, but age, gender, and heart disease risks play a part. Is it right for you?

Very Low-Risk Men and Women Who May Not Want Aspirin Therapy
Low-risk people include men under 40 and women under 50. While it helps to
know that aspirin does reduce healthy people's risk of heart disease and
stroke, their risk is low to begin with. And daily aspirin may increase their
risk of internal bleeding. For example, if 1,000 healthy people took an aspirin
daily for about six years:
- Daily aspirin would prevent three or four serious cardiovascular events
(heart attacks, strokes, or heart disease deaths).
- However, aspirin would cause about three life-threatening gastrointestinal
Unless you have risk factors for heart disease, an aspirin won't help, and
may do harm. Talk to a doctor before taking daily aspirin -- because you
Low to Medium Risk: Your Choice on Aspirin Therapy
So people at high risk should take an aspirin, and people at very low risk
shouldn't. What about everyone in between -- the vast majority of us?
The answer is: it depends. Jacobson suggests putting this question to your
doctor: Am I at high enough cardiovascular risk to justify taking an aspirin,
even with the small but real risk of significant bleeding?
"The more risk factors that you have, the greater the chance that you
will benefit" from daily aspirin, Jacobson tells WebMD.
Your doctor can calculate your cardiovascular disease risks based on the
- Your medical history
- High blood pressure
- Total and "good" cholesterol levels
- History of heart disease in close relatives
If you know your blood pressure and cholesterol, you can calculate your own
10-year risk of serious cardiovascular disease using the same tool that doctors
use. Called the "Framingham risk calculator," it's available online at:
If the benefits do outweigh the risks for you, how much aspirin should you
take? Talk to your doctor first. The standard dose is one baby aspirin (81
milligrams) a day. Higher doses are no more effective, and can cause more
Aspirin: Different Benefits for Men and Women
When it comes to heart attacks and strokes, men and women are not created
equal. Women develop cardiovascular disease later than men -- usually after
menopause, and often
well into their 70s. Their disease symptoms and survival can be very different
For many women, this difference means the risk of cardiovascular disease
doesn't justify aspirin until later in life. However, the risk of bleeding
while on aspirin also goes up with age, making the choice more complicated.
And women are different from men when it comes to the response to aspirin as
well, says Nanette Wenger, MD, spokesperson for the American Heart Association.
Based on study data:
- For healthy men aspirin seems to prevent heart attacks, but not
- For healthy women under 65, aspirin prevents strokes, but not heart
- For healthy women over 65, aspirin appears to prevent heart attacks
similarly to men.
