Abstract   Background, As a consequence of the worldwide increase in life expectancy and due to significant progress in the pharmacological and interventional treatment of heart failure (HF), the proportion of patients that reach an advanced phase of disease is steadily growing. Hence, more and more numerous group of patients is qualified to the heart transplantation (HT), whereas the number of potential heart donors has remained invariable since years. It contributes to deepening in disproportion between the demand for organs which can possibly be transplanted and number of patients awaiting on the HT list. Therefore, accurate identification of patients who are most likely to benefit from HT is imperative due to an organ shortage and perioperative complications. Purpose The aim of this study was to identify the factors associated with reduced survival during a 1.5-year follow-up in patients with end-stage HF awating HT. Method We propectively analysed 85 adult patients with end-stage HF, who were accepted for HT at our institution between 2015 and 2016. During right heart catheterization, 10 ml of coronary sinus blood was additionally collected to determine the panel of oxidative stress markers. Oxidative-antioxidant balance markers included glutathione reductase (GR), glutathione peroxidase (GPx), glutathione transferase (GST), superoxide dismutase (SOD) and its mitochondrial isoenzyme (MnSOD) and cytoplasmic (Cu/ZnSOD), catalase (CAT), malondialdehyde (MDA), hydroperoxides lipid (LPH), lipofuscin (LPS), sulfhydryl groups (SH-), ceruloplasmin (CR). The study protocol was approved by the ethics committee of the Medical University of Silesia in Katowice. The endpoint of the study was mortality from any cause during a 1.5 years follow-up. Results The median age of the patients was 53.0 (43.0–56.0) years and 90.6% of them were male. All included patients were treated optimally in accordance with the guidelines of the European Society of Cardiology. Mortality rate during the follow-up period was 40%. Multivariate logistic regression analysis showed that ceruloplasmin (odds ratio [OR] = 0.745 [0.565–0.981], p=0.0363), catalase (OR = 0.950 [0.915–0.98], p=0.0076), as well as high creatinine levels (OR = 1.071 [1.002–1.144], p=0.0422) were risk factors for death during 1.5 year follow-up. Conclusions Coronary sinus lower ceruloplasmin and catalase levels, as well as higher creatinine level are independently associated with death during 1.5 year follow-up.

Abstract Background Risk stratification is a critical component of selection process of the patients with end-stage heart failure (HF) who are considered for heart transplantation (HT). Due to the constantly increasing number of the patients placed on the transplant waiting lists and a global shortage of organs available for HT, the key issue becomes an accurate risk stratification of death and proper organ allocation to these patients who will benefit the most from this form of treatment. Purpose The aim of this study was to identify the factors associated with mortality during a 1.5-year follow-up in patients with end-stage HF awaiting HT. Methods We prospectively analysed 72 patients with advanced HF awaiting HT at our institution between 2015 and 2016. At the time of inclusion in the study routine laboratory tests, cardiopulmonary exercise test, echocardiography, and right heart catheterisation were performed in all patients. During right heart catheterisation, 10 ml of coronary sinus blood was collected. Fetuin serum concentration was measured by the sandwich enzyme-linked immunosorbent assay (ELISA) with the commercially available kit.The end-point was defined as all-cause mortality during a 1.5 years follow-up. Our medical university local Institutional Review Board approved the study protocol, and all patients provided informed consent. The study was performed in accordance with the ethical standards as laid down in the 1964 Declaration of Helsinki and its later amendments. Results Patients' median age was 53.00 (46.00–58.00) years, and 91.7% were men. During the 1.5-year follow-up, 31 (43.1%) patients died. The area under the receiver operating characteristic curve indicated a good discriminatory power of fetuin (AUC: 0.917 [95% CI: 0.858–0.977]). The cut-off point for fetuin (<632.36) had a sensitivity of 87% and a specificity of 83%. Patients with a lower fetuin level had a significantly worse 1.5-year survival compared to the group with a higher fetuin level (20.6% versus 89.5%; (long rank p<0.001). Fetuin OR 0.990 (0.986–0.996); p<0.001) and plasma sodium levels (OR, 0.640 [0.464–0.882]; p<0.001) were independent predictors of death during 1.5-year follow-up period. Conclusions Our study demonstrated that a low coronary sinus fetuin and peripheral blood sodium levels are associated with mortality patients with advanced HF accepted for HT. In addition, fetuin level, with excellent prognostic strength, allows for the risk stratification of death in analysed group of patients.

Abstract Background Despite advances in the treatment, end-stage heart failure (HF) is a disease with a severe prognosis, showing an annual mortality rate of 30 to 50%. Due to a poor prognosis in this population of patients, it is necessary to accurately stratify the risk of death, including simple and effective prognostic markers. Objective This study aimed to determine biomarkers associated with mortality in patients with end-stage HF. Material and methods The study was a prospective analysis of optimally treated patients with end-stage HF, who were hospitalised at the Cardiology Department between 2016 and 2018. At the time of enrollment to the study routine laboratory tests, cardiopulmonary exercise tests, echocardiography and right heart catheterization were performed in all patients. Human Interleukin 33 (IL-33) and IL-1 Receptor Like 1 (IL1RL1) were measured by sandwich enzyme-linked immunosorbent assay (ELISA) with the commercially available kit (Human Il-33 and IL1RL1 ELISA kit, SunRedBio Technology Co, Ltd, Shanghai, China). Plasma concentration of N-terminal brain natriuretic peptide (NT-proBNP) was measured using a commercially available kit (Human NTproBNP ELISA kit, Roche Diagnostics, Mannheim, Germany). The endpoint was all-cause mortality during a one-year follow-up. The Medical University of Silesia's local Institutional Review Board approved the study protocol, and all patients provided informed consent. Results The final study group consisted of 282 patients (87.6% males, median age 57.0 years). One-year mortality rate in the analysed population was 28%. In a multivariate analysis, independent risk factors of death included NT-proBNP [Hazard Ratio (HR) 1.056 (95% Confidence Interval (CI): 1.024–1.089); P<0.001], sodium [HR 0.877 (95% CI: 0.815–0.944); p<0.001], IL33 [HR 0.977 (95% CI: 0.965- 0.989); p<0.001] and IL1RL1 [HR 1.015 (95% CI: 1.008–1.023); p<0.001) serum levels. Conclusions Our study showed that lower sodium and IL-33 levels, as well as higher NT-proBNP and IL1RL1 levels are associated with an increased risk of death in patients with end-stage HF during a one-year follow-up.

Abstract Introduction Despite significant advances in the prevention and treatment of heart failure (HF), the prognosis for patients with advanced stage of the disease is still poor. Therefore, a better understanding of the underlying HF pathophysiological mechanisms is crucial to improve prognosis in patients with advanced HF. One important research area is the role of inflammation in the pathophysiology of HF. Purpose This study aimed to investigate factors associated with mortality in HF patients with particular emphasis placed on inflammatory markers. Methods This is a prospective analysis of 282 optimally treated HF patients hospitalised in Cardiology Department between 2016 and 2018 for heart transplantation (HT) evaluation. Patients with contraindications to HT were excluded from the study. At the baseline echocardiography, routine laboratory tests, an ergospirometric exercise test, and right heart catheterisation were performed in all patients. In addition, 10 ml of peripheral blood was collected to determine inflammatory biomarkers. Human procalcitonin and copeptin concentrations were measured by the sandwich enzyme-linked immunosorbent assay (ELISA) with the commercially available kit. A highly sensitive latex-based immunoassay was used to detect plasma C-reactive protein (CRP) using the COBAS Integra 70 analyzer. The end-point of the study was all-cause mortality during one-year follow-up. The study protocol was approved by the Local Ethics Committee of our medical university. All patients provided informed, voluntary consent to participate in the study. Results The median age of patients was 57 (51–60) and 87.6% of them were male. A total of 79 (28%) patients died during a one-year follow-up. Multivariate analysis of the Cox proportional hazard model confirmed that procalcitonin [hazard ratio (HR) 1.003 (1.002–1.003), p<0.001], high sensitivity C-reactive protein (CRP) [HR 1.109 (1.039–1.183), p<0.002], copeptin [HR 1.109 (1.019–1.207), p<0.02] and albumin [HR 0.925 (0.873–0.979), p<0.01] serum concentrations, as well as Erythrocyte Sedimentation Rate (ESR) [HR 1.031 (1.001–1.063) p<0.05] were associated with mortality during a one-year follow-up. Conclusions Our study demonstrated that higher procalcitonin, CRP and copeptin serum concentrations as well as higher ESR and lower albumin serum concentrations are independently associated with reduced survival in patients with advanced HF.

Abstract Background Oxidative stress is a cause of cardiac diseases and contribute to apoptosis, cardiac remodeling, cardiac growth and repair. The end-stage heart failure (HF) is associated with ischemia-reperfusion, increased neurohumoral activity, cytokine stimulation and presence of inflammatory cells. Above factors are stimuli which generate free radicals and can induce oxidative stress in the heart and cause damage to essential myocardial structures and function. However, the role of oxidative stress in end-stage HF has not been fully understood. Purpose This study aimed to evaluate the prognostic value of the oxidative stress markers in ambulatory patients with end-stage HF awaiting heart transplantation (HT) during a 1.5 year follow-up period. Method The study was a prospective analysis of 85 optimally treated adult patients with end-stage HF, who were added to the HT waiting list at the Cardiology Department between 2015 and 2016. At the time of enrollment to the study routine laboratory tests, cardiopulmonary exercise test, echocardiography, spirometry and right heart catheterization were performed in all patients. During right heart catheterization, 10 ml of coronary sinus blood was additionally collected to determine total oxidant status (TOS) and total antioxidant capacity (TAC) levels. TOS and TAC were measured by Erel's method. The endpoint was all-cause mortality during a 1.5 years follow-up. The Medical University of Silesia's local Institutional Review Board approved the study protocol, and all patients provided informed consent. Results Median age of the patients was 53.0 (43.0–56.0) years and 90.6% of them were male. During the observation period, the mortality rate was 40%. The area under the receiver operating characteristics (ROC) curves indicated an acceptable discriminatory power of TAC (AUC: 0.780 [CI: 0.677–0.883]; sensitivity 56%, and specificity 90%); and excellent power of TOS (AUC: 0.9530 [CI: 0.9279–0.9781]; sensitivity 88%, and specificity 94%) for 1.5 years mortality. Patients with a low TAC level (≤1.10) had a significantly worse 1.5-year survival compared to the group with a high TAC level (>1.10) (1.5 year survival: 20.8% versus 75.4%; (long rank p<0.001). Similarly, patients with a high TOS level (≥3.11) had a significantly worse survival compared to the group with a low TOS level (<3.11) (1.5- year survival: 9.1% versus 92.3%; p<0.001). Conclusion TAC with acceptable prognostic power and TOS with excellent prognostic power allows assessment of the prognosis in end-stage HF during a 1.5 year follow-up period.

Heart failure is a major public health problem and its management requires a significant amount of health care resources. Even with administration of the best available medical treatment, the mortality associated with the disease remains high. As therapeutical strategies for heart failure have been refined, the number of patients suffering from the disease has expanded dramatically. Although heart transplantation still represents the gold standard therapeutical approach, the implantation of mechanical circulatory support devices (MCSDs) evolved to a well-established management for this disease. The limited applicability of heart transplantation caused by a shortage of donor organs and the concurrent expand of the patient population with end-stage heart failure led to a considerable utilization of MCSDs. This paper outlines the current status of mechanical circulatory support.

Abstract Background Risk stratification for death and heart transplantation (HTx) in myocarditis is complex. A random forest (RF) is a tree-based machine learning technique (MLT) which is being increasingly used for clinical data analysis; it allows the detection of complex relationships between the outcome of interest and the covariates, overcoming the limits of traditional statistical analysis (i.e. regression approaches). Purpose To assess the potential role of clinical and diagnostic features at presentation as predictors of death and HTx in biopsy (Bx)-proven myocarditis using RF. Methods From January 1993 to August 2019, we consecutively enrolled 357 patients with Bx-proven myocarditis (65% male, median age 39 years, interquartile range (IQR) 26–51). An RF approach for survival data was used. Variables included in the analysis were: histology type by Bx, NYHA, type of presentation (infarct-like, arrhythmia, heart failure), viral genome detection on Bx, serum antiheart (AHA), antiintercalated disk (AIDA), anticardiac endothelial cells (AECA), antinuclear (ANA) autoantibodies, immunosuppressive therapy, cardiac catheterisation (left ventricular enddiastolic volume (LVEDV), mean capillary wedge pressure, right and left ventricular enddiastolic pressure) and 2-D echocardiographic measures (LVEDV, left ventricular ejection fraction (LVEF) at presentation and at follow-up, right ventricular fractional area change (FAC%), right ventricular diastolic area). Results The median follow-up time was of 1352 days (IQR 423.25–2535.75). At the end of follow-up, 42 patients were dead or transplanted. The 1-year, 5-year, and 10-year survival probabilities were of 0.928, 0.854, and 0.817, respectively. The most relevant predictors of death or HTx identified by the RF algorithm (according to the variable importance measure) were histological type, NYHA, clinical presentation, LVEF, and FAC%. Among the circulating auto-antibodies AECA were found to be the most important. Histological type was the strongest predictor of death/HT (100% relative importance, (RI)), giant cell myocarditis having a lower survival probability compared to other types. The next stronger predictors were advanced (III-IV) NYHA and heart failure presentation with lower survival probabilities (90% and 84% RI respectively). AECA-positive patients had lower survival probability compared to AECA negative ones (20% RI). The RF algorithm revealed an excellent predictive performance in the correct identification of all alive patients, with only 5 dead patients being misclassified (balanced accuracy 94%). Conclusions Autoimmune features, i.e Giant cell myocarditis and AECA, as well as severity of heart failure and of left ventricular disfunction at presentation were the strongest predictors of dismal prognosis. Our RF approach provides a new automated powerful tool for accurate risk stratification for death/HTx in Bx-proven myocarditis. Funding Acknowledgement Type of funding source: Public Institution(s).

Abstract Background Mutations in dystrophin gene (DMD) can cause skeletal myopathy and dilated cardiomyopathy (DCM) independently or in combination. Natural history of DMD mutation carriers and dystrophin-associated DCM is poorly understood. Objectives This study sought to describe phenotype and prognosis of DMD mutations in a large multicenter cohort of Non-Duchenne DMD mutations carriers. Methods The study cohort comprised 223 individuals with a DMD mutation (83% males, 33±15 years at first evaluation) followed at 26 European centers. Major adverse cardiac events (MACE) were defined as a composite of cardiac death, heart transplant, LVAD implantation, aborted SCD or appropriate ICD shock. Results At initial evaluation, 85 patients (38%) had DCM (52 in combination with muscular disease) and 92 (41%) had isolated muscular disease. After a median follow-up of 96 months, 112 individuals (53%) had DCM and 20% of the individuals who had normal cardiac function at baseline developed DCM. DCM penetrance by age 30 was 56%. DCM onset was associated with male sex and was independent of the type of mutation, the presence of skeletal myopathy or serum creatine kinase levels. MACE occurred in 11% and 22% individuals from the entire cohort and with DCM respectively, and were more frequent in DCM patients without muscular disease than in those with skeletal myopathy (35.5% vs 17.7%; p=0.04). Among patients with DCM, 18% developed end-stage heart failure and 9% a major arrhythmic event (SCD/aborted SCD/ICD shock/VT). There were not differences in survival between patients with isolated DCM and those with DCM and muscular phenotype. Decreased LVEF and increased left ventricular end-diastolic diameter at baseline were associated with MACE. Atrial fibrillation and neurological events were also frequent. Prognosis of individuals who did not develop DCM was good with 96% survival during follow-up. Conclusions DCM caused by mutations in DMD is characterized by moderate penetrance but a high risk of MACE, progression to end-stage heart failure and ventricular arrythmias. DCM onset is the major determinant of prognosis in DMD mutation carriers with similar survival irrespectively of the presence of concomitant muscular disease.

Abstract Background Sudden cardiac death (SCD) is responsible for 20–40% of mortality following acute myocardial infarction (AMI). The risk of SCD is even higher among patients with AMI complicated by heart failure (HF) (either clinically apparent HF or left ventricular dysfunction). The temporal relationship between an AMI complicated by HF and subsequent SCD and the association of non-fatal cardiovascular (CV) events following AMI with SCD has yet to be described. Purpose Among patients with AMI complicated by HF, we evaluated the probability and temporal association of subsequent non-fatal cardiovascular (CV) events (HF hospitalization, recurrent MI, or stroke) and SCD. Methods The High-Risk Myocardial Infarction (HRMI) database contains 28,771 patients with signs of HF or reduced LV ejection fraction (<40%) after AMI. Among patients with an AMI complicated by HF, we used adjudicated cause of death from the HRMI Database to identify: 1) the temporal distribution of SCD among patients following an index AMI; 2) the probability of having SCD following a non-fatal CV event following the index AMI. Results Median follow-up was 1.9 years. Mean age was 65.0±11.5 years and 70% were male. The incidence of CV death was 7.9 per 100 patient-year [py] and for SCD was 3.1 per 100py (40% of CV deaths). SCD rates were highest in the early period (<90 days) after AMI and decreased over time. Recurrent MI preceded 9.6% of SCD after a median time of 145 days; HF hospitalization preceded 17.0% of SCD after a median 144 days; and stroke preceded 2.7% of SCD after a median of 138 days (vs. non-sudden CV death: MI 46.6% at 1 days, HF hospitalization: 30.9% at 67 days, stroke 12.9% at 9 days). The incidence of SCD preceded by HF hospitalization was significantly higher than SCD without preceding HF hospitalization. Conclusion Among patients with AMI complicated by HF, SCD predominantly occurred in the early “high-risk” period after AMI; SCD rates decreased afterwards. Patients with non-fatal HF hospitalizations during follow-up may have a higher subsequent SCD risk. Preventing HF onset after MI may help decreasing SCD.
