Carbohydrate antigen-125 (CA-125) has recently been reported to correlate with the severity of systolic heart failure (HF). However, the association between this marker and HF with preserved ejection fraction (HFpEF) remains elusive. We studied 158 consecutive women with preserved ejection fraction, who were categorized into 3 groups: those with HF (HFpEF group, n = 35), those with ¡Ý1 cardiovascular risk (at-risk group, n = 78), and 45 normal controls (n = 45). All subjects underwent echocardiography with serum N-terminal pro-brain type natriuretic peptide (NT-ProBNP), CA-125 level, and other tumor markers obtained. HFpEF group showed significantly greater baseline levels of CA-125 and NT-ProBNP than both normal and at-risk groups (p <0.05). In addition, the serum CA-125 level correlated with the maximum left atrial volume (r = 0.24, p = 0.002). During a mean follow-up of 828.1 days (interquartile range 38 to 1,504.5), those with CA-125 levels >17.29 U/ml had a greatest incidence of HF hospitalization (hazard ratio 6.2, p <0.01) and remained an independent prognosticator in the multivariate Cox models. CA-125 superimposed on NT-ProBNP successfully expanded the receiver operating characteristic curve further in predicting HF hospitalization (area under curve 0.72 to 0.82, c-statistic 0.0049). In conclusion, serum CA-125 might serve as a novel biomarker for HFpEF and predicting HF hospitalization in women.
