Resistant to aspirin?
Ask the doctor
Q. I recently started taking low-dose aspirin, per my doctor's advice. But I heard that for some people, aspirin doesn't help prevent heart attacks. Is this true, and is there any way to find out if I'm one of those people?
A. The phenomenon you're referring to is sometimes called aspirin resistance. However, true aspirin resistance is very uncommon. There are tests for the problem, but I don't recommend them.
