RESUMO

INTRODUCTION: Accurate risk assessment in patients with heart failure (HF) is crucial. Developing new models that combine biochemical and clinical variables with novel biomarkers is the best approach to improving the management and prognostic evaluation in this population. OBJECTIVES: We aimed to assess and compare the predictive utility of a new prognostic scale, the Barcelona Bio­Heart Failure (BCN Bio­HF) risk calculator, as well as traditional risk scores, the Heart Failure Survival Score (HFSS) and the Seattle Heart Failure Model (SHFM), in patients with end­stage HF. We also searched for other risk factors associated with worse prognosis in the analyzed population. PATIENTS AND METHODS: This was a prospective analysis of 279 patients with end­stage HF listed for heart transplant between 2018 and 2021. The BCN Bio­HF, HFSS, and SHFM scores were calculated in all patients, and the accuracy of these 3 models for predicting 1­year mortality was assessed using receiver operating characteristic (ROC) analysis. RESULTS: Median (interquartile range) age of the patients was 56 (50-60) years, and 87.1% of the study population were men. During 1­year follow­up, a total of 95 patients (34.1%) died. The areas under the ROC curves for predicting 1­year mortality were 0.95 (95% CI, 0.92-0.97) for BCN Bio­HF, 0.81 (95% CI, 0.76-0.86) for HFSS, and 0.7 (95% CI, 0.63-0.76) for SHFM. We found that the BCN Bio­HF (hazard ratio [HR], 1.015; 95% CI, 1.012-1.019; P <0.001) and HFSS scores (HR, 2.801; 95% CI, 1.848-4.237; P <0.001), along with the circulating bilirubin concentration (HR, 1.015; 95% CI, 1.002-1.028; P = 0.02), were associated with 1­year mortality in the analyzed population. CONCLUSIONS: The BCN Bio­HF risk score had significantly better prognostic performance than HFSS or SHFM. Lower BCN and HFSS scores and a higher bilirubin concentration were independently associated with a higher risk of 1­year death in patients with end­stage HF.

RESUMO

BACKGROUND: Growth differentiation factor-15 (GDF-15) is a hormone that regulates inflammatory responses, tissue repair, and cardiac remodeling, the three key processes underlying the development and progression of heart failure (HF). Furthermore, GDF-15 integrates information from cardiac and extracardiac disease pathways that are linked to multiorgan dysfunction in advanced stages of HF. AIM: This study aimed to determine which factors are associated with one-year mortality in patients with end-stage HF, with particular emphasis on GDF-15. METHODS: We prospectively analyzed 315 consecutive hospitalized patients with end-stage HF who underwent heart transplantation evaluation between 2018 and 2022. The endpoint was all-cause mortality during one-year follow-up. We measured routine laboratory parameters and the serum GDF-15 concentration using a sandwich enzyme-linked immunosorbent assay (ELISA) (SunRedBio Technology Co, Ltd, Shanghai, China). RESULTS: The median age of the patients was 57 (50-62) years. During follow-up, 97 patients died. Higher serum concentrations of GDF-15 (hazard ratio [HR], 1.119; 95% CI, 1.095-1.144; P <0.001), high-sensitivity C-reactive protein (HR, 1.140; 95% CI, 1.037-1.253; P = 0.006), fibrinogen (HR, 1.003; 95% CI, 1.001-1.005; P = 0.003), bilirubin (HR, 1.055; 95% CI, 1.027-1.084; P <0.001), N-terminal pro-B-type natriuretic peptide (HR, 1.342; 95% CI, 1.206-1.493; P <0.001), and gamma-glutamyl transpeptidase (HR, 1.007; 95% CI, 1.002-1.012; P = 0.003) were independently associated with one-year mortality. CONCLUSIONS: Higher GDF-15, high-sensitivity C-reactive protein, fibrinogen, bilirubin, gamma-glutamyl transpeptidase, and N-terminal pro-B-type natriuretic peptide concentrations were independently associated with worse survival in patients with end-stage HF.

RESUMO

The role of oxidative/antioxidative system imbalances in advanced heart failure (HF) has not been fully investigated. The aim of this study was to identify factors associated with one-year mortality in patients with advanced HF, with particular emphasis on oxidative/antioxidative balance parameters. We analyzed 85 heart transplant candidates who were hospitalized at our institution for right heart catheterization. Ten milliliters of coronary sinus blood was collected to measure oxidative/antioxidative markers. The median age was 58 (50-62) years, and 90.6% of them were male. The one-year mortality rate was 40%. Multivariable logistic regression analysis revealed that ceruloplasmin (OR = 1.342 [1.019-1.770], p = 0.0363; per unit decrease), catalase (OR = 1.053 [1.014-1.093], p = 0.0076; per unit decrease), and creatinine (OR = 1.071 [1.002-1.144], p = 0.0422; per unit increase) were independently associated with one-year mortality. Ceruloplasmin, catalase, and creatinine had areas under the curve of 0.9296 [0.8738-0.9855], 0.9666 [0.9360-0.9971], and 0.7682 [0.6607-0.8756], respectively. Lower ceruloplasmin and catalase in the coronary sinus, as well as higher creatinine in peripheral blood, are independently associated with one-year mortality in patients with advanced HF. Catalase and ceruloplasmin have excellent prognostic power, and creatinine has acceptable prognostic power, allowing the distinction of one-year survivors from nonsurvivors.

RESUMO

Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and cells' ability to neutralize them by antioxidant systems. The role of oxidative stress in hypertrophic cardiomyopathy (HCM) is not fully understood. The aim of the study was to examine selected parameters of oxidative stress in patients with HCM compared to the control group. We enrolled 85 consecutive HCM patients and 97 controls without HCM. The groups were matched for sex, the body mass index, and age. Oxidative stress markers included superoxide dismutase (SOD), ceruloplasmin (CER), and lipofuscin (LPS). The median age of the HCM patients was 53 (40-63) years, and 41.2% of them were male. HCM patients, compared to the control ones, had significantly increased levels of CER and LPS. The areas under the receiver operating characteristics curves (AUC) indicated a good discriminatory power of CER (AUC 0.924, sensitivity 84%, and specificity 88%), an acceptable discriminatory power of LPS (AUC 0.740, sensitivity 66%, and specificity 72%), and poor discriminatory power of SOD (AUC 0.556, sensitivity 34%, and specificity 94%) for HCM detection. CER with good predictive strength, as well as LPS with acceptable predictive power, allows for HCM detection. The utility of SOD for HCM detection is limited.
