Your cardiologist put you on aspirin to prevent your platelets from sticking together and forming blood clots (which DOES reduce the risk of heart attack). Although it is widely established that aspirin also reduces inflammation, I don't think it is yet known whether aspirin affects the type of inflammation that the C-reactive protein is an indicator of.
Don't some people recommend that patients have their C-reactive protein levels checked as a means of assessing their risk?
Sheesh, I cannot keep up with everything!
