BOSTON, MA — Cardiovascular side effects aren't limited to the use
of the newer painkillers called COX-2 inhibitors-a category that
includes Celebrex and the recently discontinued Vioxx and Bextra. Old
standbys, like ibuprofen and aspirin, aren't entirely blameless,

aspirin, and COX-2s all belong to the class of medicines called

They can also impair blood vessels' ability to relax and may stimulate
the growth of smooth muscle cells inside arteries. All these changes
can contribute to the artery-clogging process known as atherosclerosis.
