Data on hepcidin levels in patients with heart failure (HF) are contradictory and do not make clear its contribution to the progression of multiple organ failure. There remain a number of issues about the prognostic significance of the N-terminal pro-brain natriuretic peptide (NT-proBNP) in HF with preserved ejection fraction (EF). The authors suggested the relationships between these markers in decompensated HF, as well as their associations with other clinical and laboratory parameters.Aim. To identify the association of NT-proBNP and hepcidin levels with clinical and laboratory parameters in patients with HF with various severity of left ventricular (LV) systolic dysfunction.Material and methods. The study included 68 patients (29 women, 39 men; mean age — 72,3±11,7 years) hospitalized due to decompensated HF. Patients were divided into three groups: reduced (HFrEF) (n=20), mid-range (HFmrEF) (n=23), and preserved EF (HFpEF) (n=24). Upon admission, along with standard diagnostic tests, all patients were examined for NT-proBNP and hepcidin levels by enzyme-linked immunosorbent assay. Statistical processing was carried out using the software package Statistica 8.0.Results. NT-proBNP levels in the entire sample was 315,9 [129,9; 576,1] pg/ml. Significantly higher concentrations of NT-proBNP were found in patients with lower EF: 433,05 (346,8-892,6) pg/ml for HFrEF, 289,97 (185,9-345,3) pg/ml for HFmrEF pg/ml and 214,98 (207,37-562,31) pg/ ml for HFpEF (p<0,05). At the same time, hepcidin levels in the HFrEF group (31,63 ng/ml [22,0; 71,6]) was significantly higher than in the HFmrEF (23,89 ng/ml [21,1; 27,9]) (p<0,05) and HFpEF (26,91 ng/ml [18,6; 31,1]) (p<0,05). In HFpEF patients, there was a correlation of hepcidin level with body mass index (r=0,47, p<0,05) and chronic obstructive airway diseases (r=0,44, p<0,05). A correlation of hepcidin level with cardiac arrhythmias (r=0,61, p<0,05) was revealed in the HFmrEF group. In the HFrEF group, there were correlations of a significantly increased level of NT-proBNP (median — 433,05; 95% confidence interval: 346,8-892,6) with indicators of disease severity and multiple organ dysfunction: decrease in systolic blood pressure, cardiorenal syndrome, decrease in hemoglobin level and mean corpuscular hemoglobin concentration, characteristic of iron-deficiency anemia.Conclusion. Patients with lower EF showed higher NT-proBNP values and a trend towards higher hepcidin levels. Relationships of hepcidin and NT-proBNP levels with following clinical parameters were found: body mass index, presence of obstructive airway diseases, cardiac arrhythmias, as well as low cardiac output syndrome, cardiorenal syndrome and anemia.

Data on the changes in hepcidin levels in heart failure (HF) patients are contradictory and do not give an answer about its effect on the progression of multiple organ failure. Since the model of end-stage liver disease excluding INR (MELD-XI) reflects the severity of liver and kidney dysfunction, these markers have been suggested to be associated with decompensated HF.Aim. To assess the MELD-XI score and serum hepcidin levels in patients with decompensated HF with different values of left ventricular ejection fraction (EF).Material and methods. The study included 68 patients (29 women, 39 men; mean age 72,3±11,7 years) hospitalized due to decompensated HF. Patients were divided into three groups: reduced (HFrEF) (n=20), mid-range (HFmrEF) (n=23), and preserved EF (HFpEF) (n=24)). Upon admission, along with standard diagnostic tests, all patients were examined for hepcidin-25 levels by enzyme-linked immunosorbent assay. MELD-XI score was calculated. Statistical processing was carried out using the software package Statistica 8.0.Results. Hepcidin levels in the HFrEF group (31,63 ng/ml [22,0; 71,6]) were significantly higher than in the HFmrEF (23,89 ng/ml [21,1; 27,9]) (p<0,05) and HFpEF (26,91 ng/ml [18,6; 31,1]) (p<0,05) groups. In HFpEF, there was a correlation of hepcidin level with body mass index (r=0,47, p<0,05) and chronic obstructive airway diseases (r=0,44, p<0,05). A correlation of hepcidin level with significant cardiac arrhythmias (r=0,61, p<0,05) was revealed in HFmrEF patients. MELD-XI score were significantly increased from 9,44±3,96 for HFpEF and 11,53±3,82 for HFmrEF to 14,3±4,3 for HFrEF (p<0,005). We also revealed correlation of MELD-XI score with hepcidin levels (r=0,3, p<0,05) and EF (r=-0,43, p<0,0003). Patients with a MELD-XI score of >10,4 were more likely to have NYHA class III-IV HF, HFrEF and significantly higher levels of hepcidin (p<0,05 for all) These patients were also more likely to have chronic kidney disease (p<0,05).Conclusion. Hepcidin level and MELD-XI score in patients with decompensated HF are inversely related to left ventricular EF. There is a direct relationship between hepcidin levels and other clinical parameters: body mass index, the presence of chronic obstructive airway diseases and cardiac arrhythmias.

Patients With Heart Failure

The identification of prognostic markers in patients with heart failure of both ischemic and non ischemic etiology is an increasing need in the era of devices therapy. Risk stratification for sudden cardiac death (SCD) remains problematic with reliance on left ventricular function which predicts total mortality rather than arrhythmic events (AE). Recently cardiac magnetic resonance was employed to predict susceptibility for malignant arrhythmias. This study sought to determine the utility of late gadolinium enhancement (LGE) to predict AE. Three hundred consecutive patients with symptomatic heart failure and systolic dysfunction of both ischemic and non ischemic cause undergoing CMR, were classified into two groups attending to the presence (n 160) or absence of LGE (n 140), and were followed prospectively during 842 days. The primary endpoint was the combined of SCD or Ventricular tachycardia (VT). 23 patients had AE (8 SCD/15 VT) during the follow-up, 19 of them presenting LGE (83%). The presence of LGE was associated to a significantly higher AE rate (11.8.% vs 2.8% p< 0.001)(figure ). Compared to patients without LGE, midwall fibrosis and an ischemic pattern of LGE predicted AE. (3% vs 5% vs 14%, p= 0.001) LGE is a new non-invasive predictor of AE in patients with heart failure and systolic dysfunction. This suggest a potential role for risk stratification and better selection of patients who needs device therapy
