Authors' conclusion

MRAs did not influence SGLT2i effects on the composite of HHF/CVD, HHF or all-cause mortality; however, findings hinted at a more pronounced relative reduction in CVD in chronic HF patients regardless of EF who were randomized to SGLT2i and receiving an MRA compared to those randomized to SGLT2i and not receiving MRAs. SGLT2i attenuated the risk of MRA-associated treatment-emergent hyperkalaemia.

Study context

Population
People with heart failure (HF) regardless of ejection fraction (EF), with or without mineralocorticoid receptor antagonist (MRA) use
Participants
21,947 people · 5 studies
Comparison
SGLT2 inhibitors vs placebo, by concomitant MRA use
Outcome
Composite of:
  • First hospitalization or urgent visit for HF/CV death (HHF/CVD)
  • HHF
  • CVD

Further pooled results

All-cause mortality and adverse renal endpoints, by MRA use

SGLT2i reduced all-cause mortality regardless of MRA use
P for interaction = 0.27

P for interaction = 0.73

Safety

Volume depletion and hyperkalaemia, by MRA use

Higher risk of volume depletion with concomitant MRAs
P for interaction = 0.082
SGLT2i attenuated MRA-associated mild hyperkalaemia
P for interaction < 0.001
