Patients taking Plavix, PPIs have 25 percent increased chance of death, rehospitalization

TUESDAY, March 3 (HealthDay News) -- Heart attack patients given the blood thinner Plavix, plus a proton pump inhibitor such as Prilosec or Nexium, may be at increased risk of death or another heart attack, a new study finds.

Many patients are given Plavix (clopidogrel) to help reduce the risk of another heart attack after treatment for a first heart attack. Plavix makes blood platelets less sticky, helping to prevent clots from forming.

Many doctors also prescribe proton pump inhibitors (PPIs), which are drugs used to help prevent gastric reflux, but they help prevent gastrointestinal bleeding while taking Plavix.

"A lot of patients are on Plavix and also a lot of patients are being prescribed PPI medication just prophylactically to prevent a stomach bleed," said lead researcher Dr. P. Michael Ho, a cardiologist at the Denver VA Medical Center.

The study doesn't change the reasons for prescribing Plavix, Ho said. "But both clinicians and patients should look at why the PPI is being prescribed. It shouldn't be prescribed prophylactically just to prevent a GI bleed, because there might be an interaction between the PPI and Plavix," he said.

A proton pump inhibitor should only be prescribed to patients who have had a stomach bleed, since they are at higher risk of another bleed, Ho said. "Oftentimes, the PPIs are just being prescribed routinely to patients who may not have an indication for the medication," he noted.

For the study, Ho's team collected data on 8,205 patients discharged from 127 Veterans Affairs hospitals after suffering a heart attack or unstable angina. Among these patients, 63.9 percent were prescribed a proton pump inhibitor.

The researchers found that 29.8 percent of patients given a PPI and Plavix died or were re-hospitalized, compared with 20.8 percent of the patients
