Heart failure & cardiomyopathies

Distinct Inflammatory Milieu in Patients With Right Heart Failure

Circ Heart FailPublished Mechanistic study

Authors' conclusion

RHF is associated with a distinct circulating inflammatory profile. Soluble CD163 and CXCL12 are novel biomarkers that can prognosticate patient outcomes.

Study context

Population
Patients undergoing right heart catheterization (blood from inferior vena cava and hepatic veins)
Comparison
Right heart failure (RHF) vs HF without RHF vs controls
Outcome
Circulating inflammatory markers (multiplex protein assay)
Methodological detailsindependent validation cohort
  • Independent validation cohort

Main finding

As reported in the abstract

  • RHF associated with elevated levels of a subset of cytokines/chemokines/growth factors vs controls
  • Soluble CD163 and CXCL12 higher in RHF
  • Soluble CD163 and CXCL12 predicted LV assist device/transplant-free survival in an independent validation cohort

Further findings

Hepatic expression (single-cell RNA sequencing, immunohistochemistry of human liver biopsies)

Soluble CD163 and CXCL12 expressed by Kupffer cells; may be liver derived
