OBJECTIVES The aim of this study was to evaluate the association between antigen carbohydrate 125 (CA125) and the risk of 1-year clinical outcomes in patients with worsening heart failure (HF).

BACKGROUND CA125 is a widely available biomarker that is up-regulated in patients with acute HF and has been postulated as a useful marker of congestion and risk stratification.

METHODS hi a large multicenter cohort of patients with worsening HF, either in-hospital or in the outpatient setting, the independent associations between CA125 and 1-year death and the composite of death/HF readmission (adjusted for outcome-specific prognostic risk score [BIOSTAT risk score]) were determined by using the Royston-Parmar method (N = 2356). In a sensitivity analysis, the prognostic implications of CA125 were also adjusted for a composite congestion score (CCS). Data were validated in the B1OSTAT-CHF (Biology Study to Tailored Treatment in Chronic Heart Failure validation) cohort (N = 1,630).

RESULTS Surrogates of congestion, such as N-terminal pro-B-type natriuretic peptide and CCS, emerged as independent predictors of CA125. In muttivariabte survival analyses, higher CA125 was associated with an increased risk of mortality and the composite of death/HF readmission (p <0.001 for both comparisons), even after adjustment for the CCS (p <0.010 for both comparisons). The addition of CA125 to the B1OSTAT score led to a significant risk reclassification for both outcomes (category-free net reclassification improvement 0.137 [p <0.001] and 0.104 [p 0.003] respectively). AR outcomes were confirmed in an independent validation cohort.

CONCLUSIONS In patients with worsening HF, higher levels of CA125 were positively associated with parameters of congestion. Furthermore, CA125 remained independently associated with a higher risk of clinical outcomes, even beyond a predefined risk model and clinical surrogates of congestion.
