The Claim

In adults with type 2 diabetes, once-weekly exenatide does not significantly reduce all-cause mortality or the composite outcome of death or heart failure hospitalization in those with preexisting heart failure (HR 1.05 and HR 1.07, respectively), whereas it is associated with a 21% reduction in mortality in those without heart failure, indicating that preexisting heart failure modifies the treatment effect of exenatide on cardiovascular outcomes.

In plain English

If you have type 2 diabetes and already have heart failure, the weekly diabetes shot exenatide might not help you live longer or keep you out of the hospital for heart problems. But if your heart is healthy, it could lower your risk of dying by 21%.

See the scientific wording

The cardiovascular benefits of once-weekly exenatide on all-cause death and the composite of death or heart failure hospitalization are attenuated in adults with type 2 diabetes who have preexisting heart failure, with no significant reduction in mortality (HR 1.05) or death/hospitalization (HR 1.07), in contrast to a 21% reduction in mortality in those without heart failure. This suggests that preexisting heart failure may modify the treatment effect of exenatide.

1 study
  1. Study: Effect of Once-Weekly Exenatide in Patients With Type 2 Diabetes With and Without Heart Failure and Heart Failure-Related Outcomes: Insights From the EXSCEL Trial.

    The study found that a diabetes drug called exenatide helped lower the risk of death in people without heart failure, but not in those who already had heart failure, which supports the claim.
