Introduction: A comprehensive assessment of congestion, including circulating biomarkers, is recommended in patients with acute heart failure. The circulating biomarkers natriuretic peptides (NPs) and carbohydrate antigen-125 (CA125) could be useful for congestion assessment in ambulatory chronic heart failure (CHF), but there is only limited information about their applicability in this context. Therefore, this study aimed to examine the association of plasma CA125 and NP levels with clinical and ultrasound congestion parameters in CHF. Methods: This is a cross-sectional substudy of the Cardioren Spanish Registry, which enrolled 1,107 patients with CHF from 13 tertiary hospitals in Spain between October 2021 and February 2022. Through ambulatory visits, we performed a comprehensive assessment of congestion-related parameters, including clinical variables (orthopnea, peripheral edema, and jugular engorgement, represented by the composite congestion score [CCS]), echocardiography variables (lung B-lines and inferior vena cava [IVC] diameter), and circulating biomarkers (CA125 and NPs). The association of the NP and CA125 levels with the clinical and echocardiographic congestion parameters was examined by multiple linear and logistic regression analyses. Results: This substudy included 802 patients for whom all the biomarker parameters were available {median age, 74 (interquartile range [IQR], 63-81) years; 65% male}. The proportion of patients with left ventricular ejection fraction ≥50% and estimated glomerular filtration rate <60 was 34% and 58%, respectively. The median CCS was 0 (IQR: 0-1), with 45% of the sample exhibiting a median CCS of ≥1. The jugular engorgement, peripheral edema, and orthopnea rates were 32%, 21%, and 21%, respectively. A total of 35% of patients who underwent ultrasound examination showed lung B-lines, and the median IVC diameter was 16 mm. The median CA125 and NTproBNP levels were 14 U/mL (IQR: 9-28) and 1,382 pg/mL (IQR: 563-3,219), respectively. Multivariate analysis showed that higher CA125 levels were independently associated with higher odds of peripheral edema (p = 0. 023) and lung B-lines (p < 0. 001). Further, NTproBNP was positively associated with jugular engorgement (p < 0. 001), orthopnea (p = 0. 034), and enlarged IVC diameter (p = 0. 031). Conclusions: Clinical signs of congestion are frequent in CHF. In the ambulatory setting, NTproBNP was associated with parameters linked to intravascular congestion such as orthopnea, jugular engorgement, and IVC diameter, whereas CA125 was associated with extravascular volume overload parameters (peripheral edema and lung B-lines). |
