Painkiller showdown: which is safer for the heart?

This study looked at how two common pain relievers—celecoxib (a Coxib) and naproxen (an NSAID)—affect blood clotting in people with rheumatoid arthritis who also have heart disease or are at high risk for it. All participants took low-dose aspirin daily. The goal was to see if one pain reliever interfered more with aspirin's blood-thinning effects. Only 8 people enrolled before the study was stopped early, so results are limited.
