Full findingIn a LIVE substudy (231 HFrEF patients), liraglutide reduced natriuretic peptides only in the type-2-diabetes subgroup (NT-proBNP -25%, MR-proANP -27% vs placebo) with no change in non-diabetic patients (significant T2D interaction), indicating any neurohormonal benefit in HFrEF was confined to the diabetic subset.

SourceNielsen R et al., J Nucl Cardiol 2019;26(2):585-597 (LIVE PET substudy)Source
Full findingIn a LIVE PET sub-study (36 non-diabetic HFrEF patients), liraglutide did NOT change myocardial glucose uptake, myocardial blood flow or myocardial flow reserve versus placebo despite lowering weight and HbA1c - so the increased cardiac-event signal with liraglutide in chronic HF does not appear to be mediated by changes in myocardial perfusion or substrate uptake.

Full findingA systematic review of the two isolating GLP-1RA HFrEF RCTs (FIGHT and LIVE, combined n=541, 24-week liraglutide) found no benefit and an adverse-leaning signal - no between-group difference in FIGHT's global rank/deaths/HF rehospitalisation and no LVEF change in LIVE - concluding liraglutide use in HFrEF was associated with increased risk of HF-related outcomes.

Full findingIn a secondary analysis of the STEP-HFpEF programme, inflammation (CRP >=2 mg/L) was present in 71% of obesity-related HFpEF patients; semaglutide reduced CRP more than placebo across all baseline CRP strata, and the CRP fall was largely INDEPENDENT of the magnitude of weight loss.
