Abstract

Among 11,464 matched patients aged 80 years and older, GLP-1 RA users had a lower risk of major adverse cardiovascular events compared to DPP4i users.

  • GLP-1 RA users experienced a 14% reduction in the risk of major adverse cardiovascular events.
  • The risk of major adverse kidney events was also reduced by 14% in GLP-1 RA users.
  • All-cause hospitalization rates were 9% lower for patients using GLP-1 RAs compared to those on DPP4is.
  • A significant decrease of 18% in all-cause mortality was observed among GLP-1 RA users.
  • No significant differences in heart failure or bone fracture rates were noted between the two groups.
