Rationale and design of Dapagliflozin vErsus SacubiTrIl-valsartaN therapY in Heart Failure with reduced ejection fraction (DESTINY-HF): a pragmatic randomised controlled trial protocol

Heart failure affects almost 64 million people, with more than half of it constituting heart failure with reduced ejection fraction (HFrEF). Angiotensin receptor-neprilysin inhibitors (ARNI) and sodium-glucose cotransporter-2 (SGLT2) inhibitors (SGLT2i) are in the first line for HFrEF, but no head-to-head trials are available. Moreover, growth differentiation factor-15 (GDF-15) has been demonstrated as a promising prognostic marker, specifically for HFrEF, but has not been explored much.
