- W4313138581 abstract "Introduction: Right heart failure (RHF) is associated with worse clinical outcomes in patients with heart failure (HF) and pulmonary hypertension. Previous studies have shown elevated circulating proinflammatory cytokines in patients with HF; however, no study has compared the inflammatory signature in patients with RHF to those with HF and preserved right ventricular (RV) function. Hypothesis: We predicted that patients with RHF would have a distinct inflammatory milieu compared to normal and HF patients. Methods: We recruited adult patients undergoing right heart catheterization (RHC) and excluded those with a history of transplant, autoimmune disease, malignancy, or infection. Patients underwent blood sampling during RHC and were classified into normal, HF, and RHF cohorts a priori . We then performed multiplex protein assay on serum targeting cytokines, chemokines, and growth factors. Results: A total of 43 patients were included. HF and RHF patients had similar demographics and cardiac indices, but the RHF cohort had elevated markers of congestion characterized by higher right atrial pressure and creatinine, and a trend towards higher bilirubin (Figure). Patients with RHF had elevated levels of select proinflammatory cytokines, chemokines, and growth factors. Of the factors measured, VEGF-A, soluble CD163, and CXCL12 were predictive of all-cause mortality and LVAD/transplant-free survival. Conclusion: Patients with RHF have a distinct proinflammatory signature compared to those with preserved RV function. VEGF-A, soluble CD163, and CXCL12 predicted clinical outcomes in an advanced HF population." @default.
