Aims A decrease in carbohydrate antigen 125 (CA‐125) predicts survival advantage in chronic heart failure (HF); the impact of its variation in acute HF is unknown. We studied the association of CA‐125 decrease with prognosis in acute HF. Methods and results We studied acute hospitalized HF patients. Predictors of admission and discharge CA‐125 were determined by linear regression. Follow‐up was 1 year; endpoint was all‐cause death. The association of admission and discharge CA‐125 with mortality was assessed using a Cox‐regression analysis. A Cox‐regression analysis was also used to assess the prognostic impact of CA‐125 decrease during hospitalization. Analysis was stratified by length of hospital stay (LOS). We studied 363 patients, 51.5% male, mean age 75 ± 12 years, 51.5% ischaemic, 30.0% with preserved ejection fraction, and 57.3% with reduced ejection fraction; patients presented elevated comorbidity burden. Median LOS was 7 (5–11) days. In the subgroup of 262 patients with CA‐125 measured both at admission and at discharge, we reported a significant increase in its levels: 56.0 (26.0–160.7) U/mL to 74.0 (32.3–195.0) U/mL. Independent predictors of admission CA‐125 were higher BNP and lower creatinine. Predictors of discharge CA‐125 were higher discharge BNP, lower discharge albumin, and younger age. Both admission and discharge CA‐125 predicted mortality. During follow‐up, 75 (31.8%) patients died. A decrease in CA‐125 predicted a 68% reduction in the 1 year death risk only in patients with LOS > 10 days. Conclusions Our results suggest that an early re‐evaluation (>10 days) with CA‐125 measurement after an acute HF hospitalization may be of interest in patient management.
