Painkillers—new and
old—increase the risk for heart attack
Newswise — 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, reports the October 2006 issue
of the Harvard Heart Letter. The cardiovascular risks associated
with traditional NSAIDs are small, but worth being aware of.
Ibuprofen, aspirin, and COX-2s all
belong to the class of medicines called nonsteroidal
anti-inflammatory drugs (NSAIDs). Most of them boost blood pressure
and can counteract the effect of some blood-pressure drugs. 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.
Researchers have determined that
use of a COX-2 inhibitor increases the chances of having a heart
attack. Vioxx, which was taken off the market because of possible
heart complications, may lead to or worsen heart failure—but so can
traditional NSAIDs. In general, cardiovascular side effects are most
likely to happen in people with existing heart disease or those at
high risk for it.
The Heart Letter offers a simple
table to help people make an informed choice about pain relievers.
That choice depends in part on whether you are also taking aspirin
to protect your heart. If NSAIDs upset your stomach, try taking them
along with an acid blocker. If you don’t get relief from a
traditional NSAID and you don’t have heart disease or its risk
factors, don’t rule out a COX-2 inhibitor.
