  • Prospective cohort study
  • matched healthy control cohort

Authors' conclusion

Plasma sFlt-1 concentrations have potential as an independent predictor of survival and may be complementary to established prognostic biomarkers in HF.

Study context

Population
Patients after an episode of acute decompensated heart failure (HF)Cox model n = 695, 246 deaths
Participants
890 vs 201
Exposure
Plasma sFlt-1, placental growth factor (PlGF) and vascular endothelial growth factor (VEGF) system gene single nucleotide polymorphisms (SNPs) as prognostic biomarkers in HF
  • PEOPLEn = 890
  • Canterbury Healthy Volunteers Study (CHVS)n = 201reference
Outcome
All-cause death

Main finding

As reported in the abstract

All-cause death (Cox proportional hazards, PEOPLE)

Plasma sFlt-1 predicted survival, HR (95% CI 2.57-16.1; p < 0.001), independent of age, NT-proBNP, ischaemic aetiology, diabetic status and beta-blocker therapy

6.44

Observational data: associations, not effects.

Further findings

sFlt-1, HFrEF vs HFpEF

sFlt-1 higher in HFrEF than HFpEF
P = 0.005

rs2268616 univariately associated with death
P = 0.016
rs2268616 and rs2268614 genotypes associated with PlGF levels
