Cohort study

Sodium–glucose cotransporter 2 inhibitors vs. sitagliptin in heart failure and type 2 diabetes: an observational cohort study

Eur Heart JPublished

  • Retrospective cohort study
  • propensity-score fine stratification weighted
  • Medicare claims data

Authors' conclusion

In routine US clinical practice, SGLT2i demonstrated robust clinical effectiveness in older adults with HF and type 2 diabetes compared with sitagliptin, with no evidence of heterogeneity across the SGLT2i class or across ejection fraction.

Study context

Population
Older adults (≥65 years) with heart failure (HF) and T2DM, US Medicare claims, April 2013 to December 2019
Participants
16,253 vs 43,352
Exposure
SGLT2 inhibitors vs sitagliptin
  • SGLT2in = 16,253
  • Sitagliptinn = 43,352reference
Outcome
Composite of:
  • All-cause mortality
  • HF hospitalisation
  • Urgent visit requiring IV diuretics

Main finding

As reported in the abstract

Adjusted hazard ratio

0.72

95% CI 0.67–0.77

SGLT2i vs Sitagliptin
adjusted HR 0.72 (95% CI 0.67–0.77)

Observational data: associations, not effects.

Secondary outcomes

Primary composite outcome by SGLT2i agent, by reduced vs preserved EF, and in subgroups

Similar associations for all three SGLT2i agents, for reduced and preserved EF, and in subgroups by demographics, comorbidities and other HF treatments

Bias-calibrated HRs for the primary endpoint (negative and positive control outcomes)

Bias-calibrated HRs ranged between 0.81 and 0.89; observed benefit not fully explained by residual confounding
