To assess serum levels of tumor marker carbohydrate antigen 125 (CA125) in patients with heart failure (HF) and to investigate possible correlation with echocardiographic parameters and level of brain natriuretic peptide (BNP). We included 76 patients with different cardiac symptoms hospitalized at Clinic for heart disease and rheumatism. Control group (n = 26) was consisted of patients without signs and symptoms of HF, normal left ventricle ejection fraction (LVEF) and normal BNP level. Patients with diagnosis of HF (n = 50) were subdivided into 2 group depending on signs and symptoms of fluid overload: compensated (compHF, n = 10) and decompensated group (decompHF, n = 40). Serum CA125 and BNP were measured on admission and all patient underwent ECG recording and trans thoracic echocardiographic examination. The median CA125 level in HF group was significantly higher compared to control group (71.05 [30.70-141.47]U/ml vs 10.75 [8.05- 14.32] U/ml, p < 0.0005). Higher CA125 levels were found in decompHF group compared to compHF group (94.90 [49.75-196.75]U/ml vs 11.90 [10.25-15.80]U/ml, p < 0.0005). In decompHF group 13 of patients had pleural and/or pericardial effusion- their CA125 levels were significantly higher compared to patients without serosal effusion (n = 27) (205.10 [106.50-383.90]U/ml vs. 71.50 [47.30-109.55] U/ml, p < 0.002). We found significant difference in CA125 levels between patients with atrial fibrillation and sinus rhythm (98.40 [48.20-242.70] U/ml vs. 47.30 [12.95-99.05] U/ml, p = 0.015). There was no significant difference in CA125 levels in group with enlarged left atrium compared to normal sized atrium (p = 0.282), as well as in group with moderate/severe mitral regurgitation compared to group with no/mild mitral regurgitation (p = 0.99). Finally, levels of serum CA125 positively correlated with serum level of BNP (r = 0.293, p = 0.039), but not with LVEF (p = 0.369) and left atrium diameter (p = 0.636). Serum CA125 is elevated in decompensated HF patients: more pronounced elevation was found in patients with pleural and/or pericard effusion compared to patients with no serosal effusion. CA125 level correlated with BNP, but not with left atrium diameter nor with LVEF. Tumor marker CA125 could be used as a marker of systemic congestion and volume overload in decompensated HF. We hypothesized that high CA125 level indicates that measured high BNP is actually wet BNP.

Heart failure (HF) has very high rate of repeat hospitalizations due to HF decompensation (HHFD), sometimes very shortly after discharge for acute HF. The aim of this paper is to investigate rate of HHFD and to identify their possible predictors. Total amount of 222 patients hospitalized at Clinic for heart and vessel disease and rheumatism in acute HF were followed for next 18 months for occurrence of HHFD. During hospitalization were collected demographic data, risk factors, routine laboratory tests and admission BNP (brain natriuretic peptide), discharge BNP, percentage change of BNP during hospitalization, high sensitive troponin I, CA125 (cancer antigen125) and cystatin C. In next 18 months 129 patients (58.11%) reached end-point HHFD- mean time of its occurrence was 2.2 (95% CI=1.67-2.7) months. Patients with HHFD had more often arterial hypertension (HTA) (p=0.006), had higher BMI (p=0.035) and had higher values of bilirubin, admission BNP (p=0.031), discharge BNP (p 25 and discharge BNP are independent predictors of HHFD. This could help us to identify high-risk patients for readmission who should be monitored more frequently and treated with sophisticated drug and device therapy.

Background/Objectives: Elevated lipoprotein(a) [Lp(a)] is an independent causal risk factor for atherosclerotic cardiovascular disease and may contribute to increased coronary complexity and adverse outcomes after acute myocardial infarction (AMI). Data regarding its prognostic significance in Southeastern Europe remains limited. This study aimed to evaluate the association between elevated Lp(a) levels, coronary artery disease severity, and major adverse cardiovascular events (MACE) at 1 and 6 months after AMI. Methods: This prospective study included 150 consecutive patients with STEMI and NSTEMI enrolled between December 2024 and August 2025. MACE was defined as a composite of overall cardiac death, recurrent myocardial infarction, cerebrovascular insult, heart failure with reduced ejection fraction occurrence, and new revascularization, either PCI or CABG. Results: Patients with elevated Lp(a) had significantly greater coronary disease burden, reflected by higher mean SYNTAX scores (17.3 ± 7.0 vs. 13.8 ± 7.0; p = 0.011) and a greater proportion of intermediate- and high-risk SYNTAX classifications (p = 0.016). Although the number of diseased vessels did not differ significantly, three-vessel disease was more frequent in the elevated Lp(a) group. At 1-month follow-up, overall MACE incidence was numerically higher but not statistically significant between groups. At 6 months, heart failure with reduced ejection fraction was significantly increased in patients with elevated Lp(a) (27.7% vs. 12.2%; p = 0.027). Binary logistic regression demonstrated that elevated Lp(a) independently predicted 6-month MACE (OR 2.768, p = 0.011, 95% CI 1.262–6.072), but not 1-month outcomes. Conclusions: Elevated Lp(a) is associated with increased coronary artery disease severity and higher mid-term MACE risk after AMI.
