Characteristics and outcomes for patients with heart failure diagnosed according to the universal definition and classification of heart failure. Data from a single-center registry.

BACKGROUND: There are no data on the characteristics and outcomes for patients with heart failure (HF) with reduced (HFrEF), mildly reduced (HFmrEF), and preserved (HFpEF) ejection fraction diagnosed according to the universal definition and classification of HF. AIMS: We used the universal HF definition to compare baseline characteristics, hospital readmission and mortality rates in individuals with HFrEF, HFmrEF, and HFpEF diagnosed retrospectively. RESULTS: The study was designed as a single-center retrospective analysis of all consecutive 40732 hospital admissions between 2013 and 2021 in a tertiary department of cardiology. All patients with HF, defined according to the universal definition and classification of HF, were identified. The study included 8471 patients with a mean age of 65.1 (12.8) years, of whom 2823 (33.3%) were females. Most individuals had a prior diagnosis of HF (76.3%) and elevated N-terminal pro-B-type natriuretic peptide levels (99.0%) with a median of 1548 (629-3786) pg/ml. Mean ejection fraction (EF) was 36.2 (14.9)%. The median follow-up was 39.1 (18.1-70.5) months. The most frequent type of HF was HFrEF (n = 4947; 58.4%), followed by HFpEF (n = 1138; 28.2%) and HFmrEF (n = 2386; 13.4%). Urgent HF readmissions and all-cause deaths were highest in HFrEF (40.8% and 42.7%), followed by HFmrEF (25.4% and 31.5%) and HFpEF (15.2% and 23.8%, respectively). CONCLUSIONS: The highest rates of urgent HF readmissions and all-cause mortality were observed in patients with HFrEF, followed by HFmrEF and HFpEF. In all HF groups, the all-cause mortality rate was higher than the rates of urgent HF readmission.

Spot Urinary Creatinine Concentration in Patients with Chronic Heart Failure Identifies a Distinct Muscle-Wasting Phenotype with a Strikingly Different Risk of Mortality.

BACKGROUND: There is a raising awareness that heart failure (HF) is a highly heterogeneous, multiorgan syndrome with an increasing global prevalence and still poor prognosis. The comorbidities of HF are one of the key reasons for presence of various phenotypes with different clinical profile and outcome. Heterogeneity of skeletal muscles (SMs) quantity and function may have an impact on patient's phenotype. AIM: We intended to compare clinical characteristics of phenotypes defined by a combination of various SM mass taken as a fat-free compartment from DEXA scans and different levels of SUCR (Spot Urinary Creatinine). All-cause mortality with mortality predicted by MAGGIC in such phenotypes were compared. METHODS: In 720 HF patients with reduced ejection fraction (age: 52.3 ± 10 years, female: 14%, NYHA: 2.7 ± 0.7, LVEF: 24.3 ± 7.3%), admitted to the hospital for heart transplantation candidacy assessment, morning SUCR along with body composition scanning (DEXA) was performed. All study participants were dichotomized twice, first by low or normal appendicular muscle mass index (ASMI) and second by SUCR (Spot Urinary Creatinine) < and ≥of 1.34 g/L. Four study groups (phenotypes) were created as combinations of lower or higher SUCR and low or normal ASMI. RESULTS: Low ASMI was found in 242 (33.6%) patients, while the remaining 478 had normal muscle mass. In 446 patients (61.9%), SUCR was <1.34 g/L. During 3 years of follow-up, 223 (31.0%) patients died (all-cause). The phenotype of lower both ASMI and SUCR was associated with the highest mortality. The death rate in phenotype with both low ASMI and SUCR exceeded by 70% the risk estimated by MAGGIC. This difference was significant as judged by the 95% confidence interval for MAGGIC estimation. In Cox regression analysis adjusted for MAGGIC and parameters known to increase risk, the relative risk of patients with phenotype of low both ASMI and SUCR was elevated by 45-55% as compared to patients with all other phenotypes. The protective role of higher SUCR in patients with muscle wasting was, therefore, confirmed in Cox analysis. CONCLUSIONS: Measurement of SUCR in HF patients can identify clinical phenotypes with skeletal muscle wasting but strikingly different risk of death that is actually not captured by MAGGIC score. The higher level of SUCR was associated with similar risk independently of presence of muscle wasting. As the analysis of SUCR is cheap and easy to perform, it should be further tested as a potentially useful biomarker, which may precisely phenotype HF patients independently of their skeletal muscle status.

Expert opinion of the Heart Failure Association of the Polish Society of Cardiology, the College of Family Physicians in Poland, and the Polish Society of Family Medicine on the peri discharge management of patients with heart failure.

Despite advances in the treatment of heart failure (HF), the rate of hospitalisation for exacerbations of the disease remains high. One of the underlying reasons is that recommended guidelines for the management of HF are still too rarely followed in daily practice. Disease exacerbation requiring inpatient treatment is always afactor that worsens the prognosis, and thus signals disease progression. This is also akey moment when therapy should be modified for HF exacerbation, or initiated in the case of newly diagnosed disease. Inpatient treatment and the peri­discharge period is the time when the aetiology and mechanism of HF decompensation should be established. Therapy should be individualised based on aetiology, HF phenotype, and comorbidities; it should take into account the possibilities of modern treatment. According to the recommendations of the European Society of Cardiology (ESC), patients with HF should receive multidisciplinary management. Cooperation between the various members of the multidisciplinary team taking care of patients with HF improves the efficiency and quality of treatment. This document expands and details the information on the peri­discharge management of HF contained in the 2021 ESC guidelines and the 2022 American Heart Association (AHA)/American College of Cardiology (ACC)/Heart Failure Society of America (HFSA) guidelines.

Long-term prognostic scores may underestimate the risk of death in patients with heart failure with reduced ejection fraction in whom red cell distribution width is elevated.

INTRODUCTION: Risk prediction in patients with heart failure with reduced ejection fraction (HFrEF) is one of the key challenges for clinicians. Novel biomarkers aggregating several important pathophysiological pathways may modify the diagnostic discrimination of validated scores. The red cell distribution width (RDW) is a cheap and easily available measure of anisocytosis, and was shown to have a strong independent prognostic power in short- and medium­term prognosis in HFrEF. OBJECTIVES: Our aim was to assess the prognostic power of RDW in optimally treated chronic HFrEF, and to investigate whether different RDW may impact the prognostic accuracy of validated long­term scores in HFrEF. PATIENTS AND METHODS: The study included 551 patients at a median (interquartile range [IQR]) age of 54 (47-59) years, of whom 86.6% were men. The patients represented the median New York Heart Association class III (IQR, II-III), and ischemic etiology occurred in 56.6% of the cases. In all patients, RDW as a coefficient of variation was calculated, along with Meta­Analysis Global Group in Chronic Heart Failure Score (MAGGIC­HF) and Seattle Heart Failure Survival Model (SHFSM). RESULTS: The patients were followed for 5 years and all­cause mortality was assessed. We recorded 166 (30.1%) and 225 (40.8%) deaths at 3 and 5 years, respectively. Scores based on MAGGIC­HF and SHFSM algorithms for the respective prediction of 3- and 5­year mortality were calculated for each patient and compared with the observed mortality. There was a significant underestimation of mortality in the patients with RDW above 15.4% (reference values, 11.5%-14.5%), while in those with lower RDW SHFSM overestimated the actual risk. The excess mortality in the higher RDW group was confirmed by the Hosmer-Lemeshow statistic. CONCLUSIONS: The RDW has a strong prognostic value in chronic HFrEF, independently of the risk assessed by the MAGGIC­HF or the SHFSM score.

Prognostic Value of Spot Urinary Creatinine Concentration and Its Relationship with Body Composition Parameters in HF Patients.

BACKGROUND: Low 24-h urinary excretion of creatinine in patients with heart failure (HF) is believed to reflect muscle wasting and is associated with a poor prognosis. Recently, spot urinary creatinine concentration (SUCR) has been suggested as a useful prognostic factor in selected HF cohorts. This more practical and cheaper approach has never been tested in an unselected HF population. Moreover, neither the relation between SUCR and body composition markers nor the association of SUCR with the markers of volume overload, which are known to worsen clinical outcome, has been studied so far. The aim of the study was to check the prognostic value of SUCR in HF patients after adjusting for body composition and indirect markers of volume overload. METHODS: In 911 HF patients, morning SUCR was determined and body composition scanning using dual X-ray absorptiometry (DEXA) was performed. Univariable and multivariable predictors of log SUCR were analyzed. All participants were divided into quartiles of SUCR. RESULTS: In univariable analysis, SUCR weakly correlated with fat-free mass (R = 0.09, p = 0.01). Stronger correlations were shown between SUCR and loop diuretic dose (R = 0.16, p < 0.0001), NTproBNP (R = -0.15, p < 0.0001) and serum sodium (R = 0.16, p < 0.0001). During 3 years of follow-up, 353 (38.7%) patients died. Patients with lower SUCR were more frequently female, and their functional status was worse. The lowest mortality was observed in the top quartile of SUCR. In the unadjusted Cox regression analysis, the relative risk of death in all three lower quartiles of SUCR was higher by roughly 80% compared to the top SUCR quartile. Apart from lower SUCR, the significant predictors of death were age and malnutrition but not body composition. After adjustment for loop diuretic dose and percent of recommended dose of mineralocorticoid receptor antagonists, the difference in mortality vanished completely. CONCLUSIONS: Lower SUCR levels in HF patients are associated with a worse outcome, but this effect is not correlated with fat-free mass. Fluid overload-driven effects may link lower SUCR with higher mortality in HF.

I Am the 1 in 10-What Should I Eat? A Research Review of Nutrition in Endometriosis.

Endometriosis is a chronic, painful, estrogen-related inflammatory disease that affects approximately 10% of the female population. Endometriosis has a significant negative impact on quality of life. Nutrition may be involved in the development and severity of endometriosis. The purpose of this paper is to discuss in detail the nutritional recommendations for patients with endometriosis. This article discusses the importance of nutrients such as polyphenols, vitamins C, D and E, PUFAs, and iron in the development of endometriosis. Alternative diets, such as the Mediterranean, anti-inflammatory, vegetarian, low-nickel and low-FODMAP diets, have also been presented in the context of their potential beneficial effects on the course of endometriosis.

Sodium-Glucose Cotransporter-2 Inhibitors-from the Treatment of Diabetes to Therapy of Chronic Heart Failure.

Sodium-glucose cotransporter-2 (SGLT2) inhibitors are currently the second-line pharmacotherapy in type 2 diabetes, particularly through their effectiveness in reducing glycemia, but also due to their cardioprotective and nephroprotective effects. In light of surprisingly satisfactory results from large, randomized trials on gliflozins, SGLT2 received the highest recommendation (Class IA) with the highest level of evidence (A) in the treatment algorithm for HF with reduced LVEF in recent ESC HF guidelines. This great breakthrough in the treatment of HF is due to different mechanisms of action of gliflozins that are reported to be able to change the natural course of HF by reducing the risk of both hospitalization and death. They are recommended regardless of the patient's diabetes status. This review summarizes the up-to-date literature on their beneficial and pleiotropic impact on the cardiovascular system.

The Impact of Short-Term Outdoor Air Pollution on Clinical Status and Prognosis of Hospitalized Patients with Coronary Artery Disease Treated with Percutaneous Coronary Intervention.

BACKGROUND: The aim of this study was to determine the influence of acute exposure to air pollutants on patients' profile, short- and mid-term outcomes of hospitalized patients with coronary artery disease (CAD) treated with coronary angioplasty. METHODS: Out of 19,582 patients of the TERCET Registry, 7521 patients living in the Upper Silesia and Zaglebie Metropolis were included. The study population was divided into two groups according to the diagnosis of chronic (CCS) or acute coronary syndromes (ACS). Data on 24-h average concentrations of particulate matter with aerodynamic diameter <10 µm (PM10), sulfur dioxide (SO2), nitrogen monoxide (NO), nitrogen dioxide (NO2), and ozone (O3) were obtained from eight environmental monitoring stations. RESULTS: No significant association between pollutants' concentration with baseline characteristic and in-hospital outcomes was observed. In the ACS group at 30 days, exceeding the 3rd quartile of PM10 was associated with almost 2-fold increased risk of adverse events and more than 3-fold increased risk of death. Exceeding the 3rd quartile of SO2 was connected with more than 8-fold increased risk of death at 30 days. In the CCS group, exceeding the 3rd quartile of SO2 was linked to almost 2,5-fold increased risk of 12-month death. CONCLUSIONS: The acute increase in air pollutants' concentrations affect short- and mid-term prognosis in patients with CAD.

Managed Care after Acute Myocardial Infarction (MC-AMI) improves prognosis in AMI survivors with pre-existing heart failure: A propensity score matching analysis of Polish nationwide program of comprehensive post-MI care.

BACKGROUND: Despite improvement in acute myocardial infarction (AMI) treatment, post-discharge mortality remains high. The outcomes are supposed to be even worse in patients with post-MI heart failure (HF), as only a half of patients with newly diagnosed HF survive four years. AIMS: The study aimed to analyze whether managed care after acute myocardial infarction (MC-AMI) is associated with better survival in AMI survivors with a pre-existing diagnosis of HF. RESULTS: The study included 7228 patients with a pre-existing diagnosis of HF who survived the hospitalization for AMI in Poland between November 2017 and December 2020, of whom 2268 (31.4%) were referred for the MC-AMI program. The median follow-up was 1.5 (0.7-2.3) years. In the unmatched analysis, patients without MC-AMI had more than twice higher 12-month mortality (21.8% vs. 9.9%; P <0.01) than MC-AMI participants. The difference remained significant after propensity score matching (16,8% vs. 10.0%; P <0.01). In multivariable analysis, participation in MC-AMI was an independent factor of 12-month survival. MC-AMI participants had a lower stroke rate (1.5% vs. 3.0%; P <0.01) and fewer hospital admissions due to HF (22.9% vs. 27.6%; P <0.01). CONCLUSIONS: After propensity score matching, participation in MC-AMI was associated with lower rates of stroke, HF hospitalizations, and all-cause mortality in the 12-month follow-up and was an independent factor of 12-month survival in AMI survivors with pre-existing HF.

Cardiorenal syndrome: Decongestion in heart failure across wide spectrum of kidney pathophysiology.

Heart failure (HF) is a pathophysiologically complex disease that is exceptionally heterogeneous in terms of its etiology. It is associated with unsatisfactorily high mortality, both in-hospital and post-discharge, as well as with very frequent rehospitalizations. High phenotypic variability, coexistence of various hemodynamic disorders (such as changes in systemic and pulmonary vascular resistance, increased central venous pressure, impaired heart cardiac output, and fluid overload) and coexisting metabolic and neurohormonal disorders may eventually lead to impaired systemic perfusion. Congestion that impairs renal perfusion has a significant impact on both glomerular filtration and the renal tubular function. This review article discusses the importance of changes caused by HF in various nephron segments, phenotyping of cardiorenal syndromes, the role of effective natriuresis in decongestion, and the importance of known and new diagnostic biomarkers in predicting renal dysfunction. A better understanding of cardiac and renal interactions may help in selecting an effective, efficient and nephroprotective strategy of treatment for patients with HF.

An expert opinion of the Heart Failure Association of the Polish Cardiac Society on the 2021 European Society of Cardiology guidelines for the diagnosis and treatment of acute and chronic heart failure: Heart failure guidelines from a national perspective.

The Polish expert opinion of the Heart Failure Association of the Polish Cardiac Society on the 2021 European Society of Cardiology (ESC) guidelines for the diagnosis and treatment of heart failure points to differences in many aspects related to heart failure in Poland compared with other European countries. These differences include population issues, epidemiology, diagnostic and treatment options, or the organization of healthcare. This expert opinion also includes a review of new results of clinical trials completed after the publication of the ESC guidelines.

Nutritional and Non-Nutritional Predictors of Low Spot Urinary Creatinine Concentration in Patients with Heart Failure.

Low spot urinary creatinine concentration (SUCR) is a marker of muscle wasting and clinical outcome. The risk factors for low SUCR in heart failure (HF) remain poorly understood. We explored the risk factors for low SUCR related to poor outcomes. In 721 HF patients (age: 52.3 ± 11 years, female: 14%, NYHA: 2.7 ± 0.7) SUCR and Dexa body composition scans were performed. BMI prior HF-onset, weight loss, and appendicular muscle mass were obtained. Each patient was classified as malnutrition or normal by GLIM criteria and three other biochemical indices (CONUT, PNI, and GRNI). Sarcopenia index (SI) as creatinine to cystatin C ratio was also calculated. Within 1 year, 80 (11.1%) patients died. In ROC curve we identified a SUCR value of 0.628 g/L as optimally discriminating surviving from dead. In low SUCR group more advanced HF, higher weight loss and catabolic components of weight trajectory (CCWT), more frequent under-nutrition by GLIM, and lower SI were observed. In multivariate analysis the independent predictors of low SUCR were SI, CCWT, and GNRI score. In conclusion: the risk of low SUCR was associated with a worse outcome. Low SUCR was associated with greater catabolism and sarcopenia but not with biochemical indices of malnutrition.

Ceruloplasmin as Redox Marker Related to Heart Failure Severity.

This study examined ceruloplasmin levels in patients with HFrEF, depending on cardiopulmonary exercise testing (CPET) parameters; a correlation was found between ceruloplasmin (CER) and iron and hepatic status, inflammatory and redox biomarkers. A group of 552 patients was divided according to Weber's classification: there were 72 (13%) patients in class A (peak VO2 > 20 mL/kg/min), 116 (21%) patients in class B (peak VO2 16-20 mL/kg/min), 276 (50%) patients in class C (peak VO2 10-15.9 mL/kg/min) and 88 (16%) patients in class D (peak VO2 < 10 mL/kg/min). A higher concentration of CER was found in patients with peak VO2 < 16 mL/kg/min and VE/CO2 slope > 45 compared to patients with VE/CO2 slope < 45 (escectively CER 30.6 mg/dL and 27.5 mg/dL). A significantly positive correlation was found between ceruloplasmin and NYHA class, RV diameter, NT-proBNP, uric acid, total protein, fibrinogen and hepatic enzymes. CER was positively correlated with both total oxidant status (TOS), total antioxidant capacity (TAC) and malondialdehyde. A model constructed to predict CER concentration indicated that TOS, malondialdehyde and alkaline phosphatase were independent predictive variables (R2 0.14, p < 0.001). CER as a continuous variable was an independent predictor of pVO2 ≤ 12 mL/kg/min after adjustment for sex, age and BMI. These results provide the basis of a new classification to encourage the determination of CER as a useful biomarker in HFrEF.

Serum Sulfhydryl Groups, Malondialdehyde, Uric Acid, and Bilirubin as Predictors of Adverse Outcome in Heart Failure Patients due to Ischemic or Nonischemic Cardiomyopathy.

Oxidative stress plays a significant role in the pathogenesis of heart failure (HF). The aim of the study was to investigate the prognostic value of oxidation-reduction (redox) markers in patients with HF due to ischemic and nonischemic cardiomyopathy. The study included 707 patients of HF allocated into two groups depending on ethology: ischemic cardiomyopathy (ICM) (n = 435) and nonischemic cardiomyopathy (nICM) (n = 272), who were followed up for one year. The endpoint occurrence (mortality or heart transplantation) in a 1-year follow-up was similar in the ICM and nICM group. The predictive value of endpoint occurrence of oxidative stress biomarkers such as the serum protein sulfhydryl groups (PSH), malondialdehyde (MDA), uric acid (UA), bilirubin, and MDA/PSH ratio and other clinical and laboratory data were assessed in both groups (ICM and nICM) separately using univariate and multivariate Cox regression analyses. In multivariate analysis, the higher concentrations of UA (p = 0.015, HR = 1.024, 95% CI (1.005-1.044)) and MDA (p = 0.004, HR = 2.202, 95% CI (1.296-3.741)) were significantly associated with adverse prognosis in patients with ICM. Contrastingly, in patients with nICM, we observed that higher bilirubin concentration (p = 0.026, HR = 1.034, 95% CI (1.004-1.064)) and MDA/PSH ratio (p = 0.034, HR = 3.360, 95% CI (1.096-10.302)) were significantly associated with increased risk of death or HT. The results showed the association of different oxidative biomarkers on the unfavorable course of heart failure depending on etiology.

Iron deficiency contributes to resistance to endogenous erythropoietin in anaemic heart failure patients.

AIMS: Abnormal endogenous erythropoietin (EPO) constitutes an important cause of anaemia in chronic diseases. We analysed the relationships between iron deficiency (ID) and the adequacy of endogenous EPO in anaemic heart failure (HF) patients, and the impact of abnormal EPO on 12-month mortality. METHODS AND RESULTS: We investigated 435 anaemic HF patients (age: 74 ± 10 years; males: 60%; New York Heart Association class I or II: 39%; left ventricular ejection fraction: 43 ± 17%). Patients with EPO higher than expected for a given haemoglobin were considered EPO-resistant whereas those with EPO lower than expected - EPO-deficient. ID was defined as serum ferritin <100 µg/L or 100-299 µg/L with transferrin saturation <20%. EPO-resistant patients (22%) had more advanced HF whereas those with EPO deficiency (57%) were more frequently females and had worse renal function. Lower serum ferritin (indicating depleted body iron stores) was related to higher EPO observed/predicted ratio when adjusted for significant clinical confounders, including C-reactive protein. One year all-cause mortality was 28% in patients with EPO resistance compared to 17% in patients with EPO deficiency and 10% in patients with adequate EPO (log-rank test for the comparison EPO resistance vs. adequate EPO: P = 0.02). When adjusted for other prognosticators, there was still a trend towards increased 12-month mortality in patients with higher EPO level. CONCLUSION: Anaemic HF patients with endogenous EPO deficiency vs. resistance have different clinical and laboratory characteristics. In such patients, ID contributes to EPO resistance independently of inflammation.

Expert opinion of the Heart Failure Working Group of the Polish Cardiac Society on the use of dapagliflozin in the treatment of heart failure with reduced ejection fraction.

Heart failure (HF) is a global health problem inherent in an aging population with coexisting cardiovascular diseases. Based on data from the Polish National Health Fund (Polish, Narodowy Fundusz Zdrowia), approximately 1.2 million people in Poland currently suffer from HF, and 140 000 of them die annually. Recently, Poland was ranked fifth among the European Union countries regarding the number of patients with diagnosed HF and first in terms of the number of HF hospitalizations (547 per 100 000 population) among 34 countries associated in the Organization for Economic Cooperation and Development. In recent years, a significant progress has been made in the diagnosis and treatment of HF with reduced left ventricular ejection fraction (HFrEF), which has resulted in a reduction in cardiovascular and total mortality. Despite these advantages, 5-year survival in the course of HF is still worse than that observed in some types of cancer, both in the populations of men and women. Hence, the search for drugs improving the prognosis in this group of patients is still ongoing. Sodium-glucose cotransporter 2 inhibitors represent a new group of drugs that will undoubtedly be a milestone in the treatment of patients with HFrEF. This expert opinion covers the history of dapagliflozin, which, from a drug dedicated to the treatment of type 2 diabetes, has become one of the most effective drugs improving prognosis and quality of life as well as reducing the number of hospitalizations in patients with HF. This document presents the opinion from the experts of the Heart Failure Working Group of the Polish Cardiac Society on the most relevant studies on dapagliflozin and indications for its use.

Long term outcome of heart failure patients disqualified from heart transplantation.

BACKGROUND: The prognosis of patients with advanced heart failure is unfavourable. However, little is known about the survival of patients referred for heart transplantation but finally disqualified from transplantation due to contraindications. This study aimed to evaluate the prognosis of patients' disqualified from heart transplantation. METHODS: It was a retrospective study based on medical records of patients disqualified from heart transplantation. RESULTS: One hundred and fifty-one patients were included and 94 deaths were recorded during long-term follow-up (range 0.02-10.1 years). The survival rate at 5 years was 25%. The mean age of the studied population was 57.7 years and the majority of patients were males, 87.4%. The ischaemic aetiology (66.2%) was the most dominant aetiology of heart failure. In the Cox regression model, supervision by the specialist cardiology centre (HR 0.61;p = 0.04) and pharmacotherapy with beta-blockers (HR = 0.47;p = 0.02) positively influenced the prognosis. On the contrary, well-known heart failure risk factors like a renal failure (HR 1.59;p = 0.049), pulmonary hypertension (HR 1.55;p = 0.046), liver failure (HR 2.65;p = 0.02) were negative predictors of outcome. By Kaplan-Meier analysis, patients with other than pulmonary hypertension causes of disqualification from heart transplantation had a better survival rate, p = 0.047. CONCLUSIONS: The prognosis of patients disqualified from heart transplantation is unfavourable. However, some of the patients experience relatively long survival. Therefore, careful clinical assessment and identification of factors influencing prognosis may improve adequate patients' qualifications for heart transplantation.
