Effect of dapagliflozin in DAPA-HF according to background glucose-lowering therapy
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
Research design and methods: We examined the effect of study treatment by the use or not of GLT, and by GLT classes and combinations. The primary outcome was a composite of worsening HF (hospitalization or urgent visit requiring intravenous therapy) or cardiovascular death.
Results: In the 2139 type 2 diabetes patients, the effect of dapagliflozin on the primary outcome was consistent by GLT use/no use (hazard ratio 0.72 [95%CI 0.58-0.88] versus 0.86 [0.60-1.23]; P-interaction=0.39) and across GLT classes.
Conclusions: In DAPA-HF, dapagliflozin improved outcomes irrespective of use/no use of GLT or by GLT type used in patients with type 2 diabetes and HFrEF.
