No Link Between PPI Use and Risk for Cardiovascular Events


TOPLINE:

There is no significant association between the use of proton pump inhibitors (PPIs) and risk for cardiovascular events, a meta-analysis shows. However, patients with gastroesophageal reflux disease (GERD) do experience a slight increase in cardiovascular events with PPI use.

METHODOLOGY:

  • PPIs are commonly used gastric acid suppressants; however, they have pleiotropic effects, some of which have been hypothesized to augment cardiovascular disorders.
  • Researchers conducted a meta-analysis of randomized clinical trials with at least 100 patients and treatment durations > 30 days, which compared groups receiving PPIs to those on placebo or other active treatments.
  • The primary outcome was a composite of nonfatal myocardial infarctions, nonfatal strokes, fatal cardiovascular adverse events, coronary revascularizations, and hospitalizations for unstable angina.

TAKEAWAY:

  • Researchers included data from 52 placebo-controlled trials, with 14,988 patients and 8323 patients randomized to receive a PPI or placebo, respectively; the mean treatment duration was 0.45 person-years for those treated with PPIs and 0.32 person-years for those treated with placebo.
  • Among placebo-controlled trials, 24 were conducted in patients with GERD.
  • Researchers also included 61 active-controlled trials that compared PPIs with histamine-2 receptor antagonists (51 trials) or other active treatments.
  • The incidence rate ratio for the primary outcome was 0.72 when comparing PPI to placebo, indicating no significant association between PPI and cardiovascular events.
  • Among patients with GERD, cardiovascular events occurred only in those treated with PPIs, leading to approximately one excess cardiovascular event per 100 person-years of PPI treatment relative to placebo.
  • Researchers found no association between PPI treatment and the risk for cardiovascular events in trials comparing PPIs with other active treatments.

IN PRACTICE:

“We found no association of cardiovascular events with PPI treatment,” the authors wrote. “Cardiovascular events appeared more frequent with PPI treatment in GERD trials, but results from this subgroup should be interpreted with the limitations of the analysis in mind.”

SOURCE:

The study, led by Andrew D. Mosholder, MD, MPH, Division of Epidemiology, US Food and Drug Administration Center for Drug Evaluation and Research, Silver Spring, Maryland, was published online in The American Journal of Gastroenterology.

LIMITATIONS:

This study lacked individual patient data, which precluded a time-to-event analysis or an analysis accounting for patient characteristics such as age or sex. The mean duration of PPI treatment in these trials was a few months, limiting the assessment of cardiovascular risk with extended use. The risk estimates were influenced the most by data on omeprazole and esomeprazole.

DISCLOSURES:

This study did not receive any funding. The authors declared no conflicts of interests.
