Tumor marker levels in patients aged 85 years and older with chronic heart failure

Prognostic value of carbohydrate antigen 125 in patients undergoing surgical left ventricular reconstruction

BACKGROUND

Carbohydrate antigen 125 (CA125) is a biomarker often used in diagnosis of ovarian tumors. Studies also show that elevated CA125 implicates worse outcomes among patients with heart failure, while latter of which plays an important role in the pathophysiology of left ventricular aneurysm (LVA). However, the prognostic value of CA125 in LVA patients undergoing surgical left ventricular reconstruction (SLVR) remains unclear.

METHODS

In this single-centered cohort study, a total of 309 patients with LVA undergoing SLVR were retrospectively recruited. Univariable regression analysis was performed to identify the potential confounders for each outcome, followed by multivariable adjustment to confirm the association between CA125 and outcomes. The primary outcome was the overall mortality, and the secondary outcome was the major adverse cardiovascular and cerebrovascular events (MACCE) and perioperative outcomes. A receiver operating characteristic (ROC) curve was use to find the optimal cut-off value of CA125.

RESULTS

The median follow-up time was 55 months. The cohort was predominantly male (86.4%), with an average age of 58.6 years. Log (CA125) was associated with overall mortality (hazard ratio [HR]: 2.15, 95% confidence interval [CI]: 1.06-4.36, P = 0.033), prolonged hospital-stay time (HR:1.07, 95%CI: 1.03-1.12, P = 0.001) and increased risk of postoperative ventricular support (HR: 2.81, 95%CI: 1.10-7.18, P = 0.031) after multivariate adjustment. The optimal cut-off value for the CA125 for all-cause mortality was 13.825 U/ml with the area under curve of 0.675.

CONCLUSION

Elevated-CA125 implicates poorer short- and long-term prognosis in LVA patients undergoing SLVR.

The Diagnostic and Therapeutic Value of Multimarker Analysis in Heart Failure. An Approach to Biomarker-Targeted Therapy

Background: Heart failure is a pathophysiological state, which is still associated with high morbidity and mortality despite established therapies. Diverse well-known biomarkers fail to assess the variety of individual pathophysiology in the context of heart failure. Methods: An analysis of prospective, multimarker-specific therapeutic approaches to heart failure based on studies in current literature was performed. A total of 159 screened publications in the field of biomarkers in heart failure were hand-selected and found to be eligible for this study by a team of experts. Results: Established biomarkers of the inflammatory axis, matrix remodeling, fibrosis and oxidative stress axis, as well as potential therapeutic interventions were investigated. Interaction with end organs, such as cardio-hepatic, cardio-renal and cardio-gastrointestinal interactions show the complexity of the syndrome and could be of further therapeutic value. MicroRNAs are involved in a wide variety of physiologic and pathophysiologic processes in heart failure and could be useful in diagnostic as well as therapeutic setting. Conclusion: Based on our analysis by a biomarker-driven approach in heart failure therapy, patients could be treated more specifically in long term with a consideration of different aspects of heart failure. New studies evaluating a multimarker - based therapeutic approach could lead in a decrease in the morbidity and mortality of heart failure patients.

CA125 as a Marker of Heart Failure in the Older Women: Population-Based Analysis

(1) Background: Cancer antigen 125 (CA125) is a glycoprotein that is expressed by tissue derived from coelomic epithelium in the pleura, peritoneum, pericardium. It has been shown that CA125 concentrations are correlated with NT-proBNP in older with congestive heart failure (HF). We conducted a study on the association between concentrations of CA125 and NT-proBNP in a population-based cohort of older Polish women. (2) Methods: The current research is sub-study of a large, cross-sectional research project (PolSenior). The study group consisted of 1565 Caucasian women aged 65-102 years. To assess the relationship between CA125 and other variables a stepwise backward multivariate normal and skew-t regression analyses were performed. (3) Results: The median of CA125 concentration was 13.0 U/mL and values over the upper normal range limit (35 U/mL) were observed in 5.1% (n = 79) of the study cohort. The concentration of CA125 was positively related to age, hospitalization for HF and history of atrial fibrillation and chronic obstructive pulmonary disease, levels of NT-proBNP, IL-6, hs-CRP and triglycerides. We found, in multivariate analyses, that increased CA125 levels were independently associated with log10 (IL-6) (β = 11.022), history of hospitalization for HF (β = 4.619), log10 (NT-proBNP) (β = 4.416) and age (β = 3.93 for 10 years). (4) Conclusion: Despite the association between CA125 and NT-proBNP, the usefulness of CA125 for the detection of HF in older women is limited by factors such as inflammatory status and age.
