Takeaway

  • In patients with type 2 diabetes (T2D), sodium-glucose co-transporter-2 inhibitors (SGLT2i) significantly reduced the risk of all-cause mortality and hospitalisations for heart failure (HF) and chronic kidney disease (CKD) compared with dipeptidyl peptidase-4 inhibitors (DPP4i), irrespective of the presence or absence of cardiovascular and renal disease (CVRD).

Why this matters

  • Findings highlight the need to introduce SGLT2i early in the management of high-risk patients with T2D.

Study design

  • The retrospective cohort study matched 24,438 patients with T2D receiving an SGLT2i (1:1) with those receiving a DPP4i using propensity score matching, stratified based on the presence of CVRD.

  • Primary outcomes: all-cause mortality, cardiovascular (CV) death or hospitalisation for HF, myocardial infarction, stroke, and CKD.

  • Funding: AstraZeneca.

Key results

  • SGLT2i vs DPP4i was associated with a lower risk of (HR; 95% CI):

    • all-cause mortality (0.73; 0.63-0.84);

    • CV mortality (0.80; 0.66-0.97); and

    • hospitalisation for HF (0.74; 0.65-0.84) and CKD (0.51; 0.47-0.856 P<.001 for all).

  • In patients without CVRD, SGLT2i vs DPP4i was associated with a lower risk of (HR; 95% CI):

    • all-cause mortality (0.71; 0.57-0.88; P=.002); and

    • hospitalisation for HF (0.76; 0.59-0.98; P=.035) and CKD (0.75; 0.63-0.88; P<.001).

  • Similarly, in patients with CV disease or at high risk, SGLT2i vs DPP4i was associated with a lower risk of (HR; 95% CI):

    • all-cause mortality (0.69; 0.59-0.82; P<.001);

    • CV mortality (0.76; 0.62-0.95; P=.014); and

    • hospitalisation for HF (0.73; 0.63-0.85; P<.001), stroke (0.75; 0.59-0.94; P=.013), and CKD (0.49; 0.43-0.54; P<.001).

  • Results were consistent across subgroups and sensitivity analyses.

Limitations

  • Retrospective.
