[PMID: 38517084 DOI: 10.14309/ajg.0000000000002775] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Accepted: 03/13/2024] [Indexed: 03/23/2024]
Abstract
INTRODUCTION Limited evidence exists on the optimal strategy to correct iron deficiency anemia after variceal bleeding (VB) in cirrhosis. This trial compared the efficacy and safety of intravenous ferric carboxymaltose (IV-FCM) with those of oral iron therapy in this cohort. METHODS In this open-label, single-center, randomized controlled trial, eligible patients with hemoglobin <10 g/dL and iron deficiency (ferritin <100 ng/mL) after VB received either IV-FCM (1,500-2,000 mg) divided into 2 doses (n = 48) or oral carbonyl iron (100 mg elemental iron/day) (n = 44) for 3 months. The primary outcome was change in hemoglobin at 3 months. Secondary outcomes included improvement in anemia (last hemoglobin >12 g/dL), normalization of iron stores (ferritin >100 ng/mL), liver-related adverse events, adverse drug reactions, and changes in quality of life (CLDQOL questionnaire). RESULTS Baseline characteristics, including median Child-Turcotte-Pugh score 7 (interquartile range [IQR] 6-9), Model for End-Stage Liver Disease score 12 (IQR 10-17), blood hemoglobin (8.25 ± 1.06 g/dL), and ferritin (30.00 ng/mL [15.00-66.50]), were comparable in both arms. The median increase in hemoglobin at 3 months in the IV and oral arms was 3.65 g/dL (IQR 2.55-5.25) and 1.10 g/dL (IQR 0.05-2.90 g/dL) ( P < 0.001), respectively. Iron stores normalized in 84.6% and 21% of the IV and oral arms, respectively ( P < 0.001). Anemia improved in 50% and 21.9% in the IV and oral arms, respectively ( P < 0.009). Patients in the IV arm showed a significant improvement in all domains of CLDQOL. Liver-related adverse events were comparable in both arms. Transient mild/moderate hypophosphatemia developed in 43% of patients receiving IV-FCM. DISCUSSION Intravenous iron replacement is efficacious and safe to treat iron deficiency anemia after VB in patients with cirrhosis.

Abstract
INTRODUCTION Anemia is a risk factor for all-cause mortality in older adults. Iron deficiency may also be associated with adverse outcomes, independent of its role in causing anemia. This study tested the hypotheses that anemia, and low ferritin among non-anemic participants, were associated with all-cause and cause-specific mortality in a community-based cohort of older adults. METHODS Fasting blood was obtained from 5,070 ARIC participants (median age: 75 years) in 2011-2013. Anemia was defined by hemoglobin concentrations <12 g/dL in women and <13 g/dL in men. We classified 4,020 non-anemic participants by quartiles of plasma ferritin, measured by the SomaScan proteomics platform. Cox proportional hazards regression was used. Mortality was ascertained via phone calls with proxies as part of twice-yearly cohort follow-up, surveillance of local hospital discharge indexes, state death records, and linkage to the National Death Index. RESULTS Of the total participants, 21% had anemia at baseline. Over a median of 7.5 years, there were 1,147 deaths, including 357 due to cardiovascular disease (CVD), 302 to cancer, and 132 to respiratory disease. Compared to those with normal hemoglobin, participants with anemia had a higher risk of all-cause mortality (hazard ratio 1.81 [95% CI: 1.60-2.06]), and mortality due to CVD (1.77 [1.41-2.22]), cancer (1.81 [1.41-2.33]), and respiratory disease (1.72 [1.18-2.52]) in demographics-adjusted models. In fully adjusted models, associations with all-cause mortality (1.37 [1.19-1.58]) and cause-specific mortality were attenuated. In non-anemic participants, lower ferritin levels were not associated with all-cause or cause-specific mortality, though associations were observed among participants with lesser evidence of inflammation (CRP below the median level of 1.9 mg/L) and for cancer mortality in men only. CONCLUSION Anemia is common among older adults and is associated with all-cause mortality, as well as mortality due to CVD, cancer, and respiratory disease. Our results do not provide evidence that iron deficiency, independent of anemia, is associated with mortality in this population.

[PMID: 38733250 PMCID: PMC11231948 DOI: 10.1093/eurheartj/ehae284] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 02/29/2024] [Accepted: 04/23/2024] [Indexed: 05/13/2024] Open
Abstract
Current understanding of iron-deficient heart failure is based on blood tests that are thought to reflect systemic iron stores, but the available evidence suggests greater complexity. The entry and egress of circulating iron is controlled by erythroblasts, which (in severe iron deficiency) will sacrifice erythropoiesis to supply iron to other organs, e.g. the heart. Marked hypoferraemia (typically with anaemia) can drive the depletion of cardiomyocyte iron, impairing contractile performance and explaining why a transferrin saturation < ≈15%-16% predicts the ability of intravenous iron to reduce the risk of major heart failure events in long-term trials (Type 1 iron-deficient heart failure). However, heart failure may be accompanied by intracellular iron depletion within skeletal muscle and cardiomyocytes, which is disproportionate to the findings of systemic iron biomarkers. Inflammation- and deconditioning-mediated skeletal muscle dysfunction-a primary cause of dyspnoea and exercise intolerance in patients with heart failure-is accompanied by intracellular skeletal myocyte iron depletion, which can be exacerbated by even mild hypoferraemia, explaining why symptoms and functional capacity improve following intravenous iron, regardless of baseline haemoglobin or changes in haemoglobin (Type 2 iron-deficient heart failure). Additionally, patients with advanced heart failure show myocardial iron depletion due to both diminished entry into and enhanced egress of iron from the myocardium; the changes in iron proteins in the cardiomyocytes of these patients are opposite to those expected from systemic iron deficiency. Nevertheless, iron supplementation can prevent ventricular remodelling and cardiomyopathy produced by experimental injury in the absence of systemic iron deficiency (Type 3 iron-deficient heart failure). These observations, taken collectively, support the possibility of three different mechanistic pathways for the development of iron-deficient heart failure: one that is driven through systemic iron depletion and impaired erythropoiesis and two that are characterized by disproportionate depletion of intracellular iron in skeletal and cardiac muscle. These mechanisms are not mutually exclusive, and all pathways may be operative at the same time or may occur sequentially in the same patients.

Packer M. Iron homeostasis, recycling and vulnerability in the stressed kidney: A neglected dimension of iron-deficient heart failure. Eur J Heart Fail 2024; 26:1631-1641. [PMID: 38727795 DOI: 10.1002/ejhf.3238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Revised: 03/26/2024] [Accepted: 03/29/2024] [Indexed: 07/26/2024] Open
Abstract
The available evidence suggests that the kidney may contribute importantly to the development of an iron deficiency state in patients with heart failure and may be injured by therapeutic efforts to achieve iron repletion. The exceptional workload of the proximal renal tubule requires substantial quantities of iron for ATP synthesis, which it derives from Fe3+ bound to transferrin in the bloodstream. Following ferrireduction, Fe2+ is conveyed by divalent transporters (e.g. DMT1) out of the endosome of the proximal renal tubule, and highly reactive Fe2+ can be directed to the mitochondria, sequestered safely in a ferritin nanocage or exported through the actions of hepcidin-inhibitable ferroportin. The actions of ferroportin, together with transferrin endocytosis and DMT1-mediated transport, play a key role in the recycling of iron from the tubular fluid into the bloodstream and preventing the loss of filtered iron in the urine. Activation of endogenous neurohormonal systems and proinflammatory signalling in heart failure decrease megalin-mediated uptake and DMT1 expression, and increase hepcidin-mediated suppression of ferroportin, promoting the loss of iron in the urine and contributing to the development of an iron deficiency state. Furthermore, the failure of ferroportin-mediated efflux at the basolateral membrane heightens the susceptibility of the renal tubules to cytosolic excesses of Fe2+, causing lipid peroxidation and synchronized cell death (ferroptosis) through the iron-dependent free radical theft of electrons from lipids in the cell membrane. Ferroptosis is a central mechanism to most disorders that can cause acute and chronic kidney disease. Short-term bolus administration of intravenous iron can cause oxidative stress and is accompanied by markers of renal injury. Experimentally, long-term maintenance of an iron-replete state is accompanied by accelerated loss of nephrons, oxidative stress, inflammation and fibrosis. Intravenous iron therapy increases glomerular filtration rate rapidly in patients with heart failure (perhaps because of a haemodynamic effect) but not in patients with chronic kidney disease, and the effects of intravenous iron on the progression of renal dysfunction in the long-term trials - AFFIRM-AHF, IRONMAN and HEART-FID - have not yet been reported. Given the potential role of dysregulated renal iron homeostasis in the pathogenesis of iron deficiency and the known vulnerability of the kidney to intravenous iron, the appropriate level of iron repletion with respect to the risk of acute and chronic kidney injury in patients with heart failure requires further study.

Abstract
Iron is an essential nutrient for humans and microbes, such as bacteria. Iron deficiency commonly occurs in critically ill patients, but supplementary iron therapy is not considered during the acute phase of critical illness since it increases iron availability for invading microbes and oxidative stress. However, persistent iron deficiency in the recovery phase is harmful and has potential adverse outcomes such as cognitive dysfunction, fatigue, and cardiopulmonary dysfunction. Therefore, it is important to treat iron deficiency quickly and efficiently. This article reviews current knowledge about iron-related biomarkers in critical illness with a focus on patients with sepsis, and provides possible criteria to guide decision-making for iron supplementation in the recovery phase of those patients.

Abstract
Iron deficiency and heart failure frequently co-occur, sparking clinical research into the role of iron repletion in this condition over the last 20 years. Although early nonrandomized studies and subsequent moderate-sized randomized controlled trials showed an improvement in symptoms and functional metrics with the use of intravenous iron, 3 recent larger trials powered to detect a difference in hard cardiovascular outcomes failed to meet their primary endpoints. Additionally, there are potential concerns related to side effects from intravenous iron, both in the short and long term. This review discusses the basics of iron biology and regulation, the diagnostic criteria for iron deficiency and the clinical evidence for intravenous iron in heart failure, safety concerns, and alternative therapies. We also make practical suggestions for the management of patients with iron deficiency and heart failure and outline key areas in need of future research.

Abstract
AIMS Among persons with prevalent heart failure (HF), iron deficiency has been linked to HF admissions, and intravenous iron replacement improves HF outcomes. Recent studies in persons with chronic kidney disease (CKD) demonstrate that iron deficiency is associated with incident HF. This study aimed to determine the relationship of iron status with incident HF in community-dwelling older adults irrespective of their kidney function. METHODS In this case-cohort study, 1,006 Cardiovascular Health Study participants (785 from the random sub-cohort [including 193 HF cases] and 221 additional HF cases [N = 414 total HF cases]) aged ≥ 65 years without HF (41% with CKD), we used weighted Cox models to evaluate associations of iron status with incident HF. Participants were categorized based on quartiles of transferrin saturation and ferritin as "iron replete" (27.3%), "functional iron deficiency" (7.7%), "iron deficiency" (11.8%), "mixed iron deficiency" (5.6%), "high iron" (9.3%) and "non-classified" (38.1%), consistent with prior studies. RESULTS Compared to older persons who were iron replete, those with iron deficiency were at higher risk of incident HF (HR 1.47; 1.02-2.11) in models adjusting for demographics, HF risk factors, and estimated glomerular filtration rate. Other iron categories did not associate with incident HF. The relationship of iron deficiency with incident HF did not differ by CKD status (interaction P value 0.2). CONCLUSIONS Among community-dwelling elders, iron deficiency is independently associated with incident HF, an association that was similar irrespective of CKD status. Our findings support conduct of clinical trials of iron replacement for prevention of HF in older adults with iron deficiency.

Abstract
BACKGROUND Iron deficiency is a common comorbidity in heart failure (HF) and is independently associated with a worse quality-of-life and exercise capacity, as well as increased risk of hospitalization, regardless of anemia status. Although international guidelines have provided recommendations for the management of iron deficiency in patients with HF, guidelines in Asia are less established, and practical use of guidelines for management of iron deficiency is limited in the region. METHODS A panel comprising cardiologists from China, Hong Kong, India, Japan, Malaysia, Pakistan, Philippines, Singapore, South Korea, Taiwan, and Thailand convened to share insights and provide guidance for the optimal management of iron deficiency in patients with HF, tailored for the Asian community. RESULTS Expert opinions were provided for the screening, diagnosis, treatment and monitoring of iron deficiency in patients with HF. It was recommended that all patients with HF with reduced ejection fraction should be screened for iron deficiency, and iron-deficient patients should be treated with intravenous iron. Monitoring of iron levels in patients with HF should be carried out once or twice yearly. Barriers to the management of iron deficiency in patients with HF in the region include low awareness of iron deficiency amongst general physicians, lack of reimbursement for screening and treatment, and lack of proper facilities for administration of intravenous iron. CONCLUSIONS These recommendations provide a structured approach to the management of iron deficiency in patients with HF in Asia.

Abstract
BACKGROUND Iron deficiency (ID) is a frequent comorbidity in patients with acute (AHF) and chronic heart failure (CHF) associated with morbidity and death. We aimed to better characterize iron homeostasis in patients with heart failure applying different biomarkers and to evaluate the accuracy of current ID definition by the European Society of Cardiology/American College of Cardiology/American Heart Association to indicate tissue iron availability and demand. METHODS AND RESULTS We performed a retrospective cohort study investigating 277 patients with AHF and 476 patients with CHF between February 2021 and May 2022. Patients with AHF had more advanced ID than patients with CHF, reflected by increased soluble transferrin receptor and soluble transferrin receptor-ferritin index, and lower ferritin, serum iron, transferrin saturation, hepcidin, and reticulocyte hemoglobin. Decreased iron availability or increased tissue iron demand, reflected by increased soluble transferrin receptor-ferritin index and decreased reticulocyte hemoglobin, was found in 84.1% (AHF) and 28.0% (CHF) with absolute ID and in 50.0% (AHF) and 10.5% (CHF) with combined ID according to the current European Society of Cardiology/American College of Cardiology/American Heart Association-based ID definition. Low hepcidin expression as an indicator of systemic ID was found in 91.1% (AHF) and 80.4% (CHF) of patients with absolute ID and in 32.3% (AHF) and 18.8% (CHF) of patients with combined ID. ID definitions with higher specificity reduce the need for iron supplementation by 25.5% in patients with AHF and by 65.6% in patients with CHF. CONCLUSIONS Our results suggest that the current European Society of Cardiology/American College of Cardiology/American Heart Association-based ID definition might overestimate true ID, particularly in CHF. More stringent thresholds for ID could more accurately identify patients with heart failure with reduced tissue iron availability who benefit from intravenous iron supplementation.

Abstract
INTRODUCTION Approximately 45% of patients with heart failure had iron deficiency for the rest of their lives. OBJECTIVE To determine the effect of iron treatment in patients with heart failure and iron deficiency or anemia. MATERIALS AND METHODS The studies were selected in: PubMed, Scopus, Cochrane and Google Scholar, from the beginning of June to July 2023. The selected articles that met the inclusion criteria, the relevant information of the studies were collected according to the selection variables and were recorded in the Revman 5.0 program of the Cochrane collaboration. The primary outcome was composed of hospitalization for heart failure or cardiovascular death. RESULTS Of the 7 included studies, 6717 patients were obtained, the average age was 70 years with a predominance of the male gender (57%). The primary outcome was lower in patients in the control group compared to the placebo group (OR, 0.62; 95%CI, 0.54-0.70). The 6-minute walk test (6-MWT) was improved in the iron-supplemented group compared to the placebo group (OR, 0.79; 95%CI, 0.64-0.98). Adverse events were fewer in the iron supplement group compared to the placebo group (OR, 0.78; 95%CI, 0.67-0.91). CONCLUSION In this meta-analysis of randomized controlled trials, the effect of iron supplementation is found to reduce the incidence rate of hospitalization for heart failure or cardiovascular death. In addition to a reduction in adverse events, such as gastrointestinal and neurological disorders, it also improves 6-MWT.

Abstract
OBJECTIVES To determine optional therapeutic strategies by comparing monotherapies and combination therapies to reduce RBC transfusion requirement for patients in the ICU. DATA SOURCES MEDLINE, CENTRAL, and Embase were searched for studies published from database inception until July 2023. DATA EXTRACTION We included randomized controlled trials comparing erythropoiesis-stimulating agents (Epo), iron, combination therapy with iron and Epo, hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI), vitamin D 3 (VD3), and placebo/no treatment. A frequentist network meta-analysis (NMA) was performed using a random effects model, and the confidence in NMA was rated. DATA SYNTHESIS Of 117 eligible studies, 75 studies (15,091 patients) were included in the quantitative analysis. Compared with placebo/no treatment, the combination therapy reduces the requirement for RBC transfusion (risk ratio [RR]: 0.60; 95% CI, 0.49-0.74; confidence rating: moderate). The Epo or iron monotherapy may reduce the requirement for RBC transfusion (RR: 0.81; 95% CI, 0.63-1.04; confidence rating: low; RR: 0.83; 95% CI, 0.70-0.98; confidence rating: low, respectively). Combination therapy may not increase the prevalence of both venous thromboembolism (VTE) (RR: 0.73; 95% CI, 0.25-2.08; confidence rating: low) and infection. Epo monotherapy may not increase the prevalence of VTE but may increase that of infections (RR: 1.27; 95% CI, 0.94-1.73; confidence rating: low). Iron monotherapy may not increase the prevalence of both VTE and infection. Evidence for VD3 and HIF-PHI remains uncertain. CONCLUSIONS Combination therapy with iron and Epo likely reduces the requirement for RBC transfusion and may be less harmful than other therapies.

Abstract
BACKGROUND There is limited evidence regarding the prevalence and impact of iron deficiency (ID) in children with dilated cardiomyopathy (DCM). METHODS Retrospective single-center review of all children between 2010 and 2020 with a diagnosis of DCM and complete iron studies. ID was defined as ≥2 of ferritin <20 μg/liter, iron <9 μmol/liter, transferrin >3 g/liter, or transferrin saturation (TSat) <15%. Clinical and laboratory indices and freedom from a composite adverse event (CAE) of mechanical circulatory support (MCS), heart transplant, or death were compared between children with and without ID. RESULTS Of 138 patients with DCM, 47 had available iron studies. Twenty-nine (62%) were iron deficient. Children with ID were more likely to be receiving inotropes (17, 59%, p = 0.005) or invasive/noninvasive ventilation (13, 45%, p = 0.016) than those who were iron replete. They had a higher incidence of anemia (22, 76%, p = 0.004) and higher NT-proBNP (1,590 pmol/liter, IQR 456-3,447, p = 0.001). Children with ID had significantly less freedom from the CAE at 1-year (54% ± 10%), 2-years (45 ± 10), and 5-years (37% ± 11%) than those without (p = 0.011). ID and anemia were the only significant predictors of the CAE on univariate Cox regression. CONCLUSIONS ID is highly prevalent in children with DCM. Iron studies are undermeasured in clinical practice, but ID is associated with severe heart failure (HF) and an increased risk of the CAE. The need for iron replacement therapy should be considered in children who present in HF with DCM.

Abstract
INTRODUCTION Iron deficiency anaemia (IDA) is common in patients with heart failure (HF) and is associated with advanced HF and increased mortality. Intravenous iron supplementation increases exercise tolerance, improves quality of life, and decreases symptoms among patients with HF with reduced ejection fraction (HFrEF) and iron deficiency. Despite this, many patients are not screened or treated for IDA. We aimed to increase rates of screening and treatment of IDA among HF patients through the introduction of curated materials to aid HF clinicians with appropriate screening and treatment. METHODS We conducted a retrospective chart review to identify the baseline number of HFrEF patients screened and treated for IDA at two ambulatory cardiology clinics in Toronto, Ontario. A quality improvement initiative was then introduced, which consisted of education and curated materials to aid clinicians in the screening and treatment of IDA among HFrEF patients. The proportion of patients screened and treated for IDA preintervention and postintervention were compared using χ2 tests of Independence. RESULTS In the preintervention cohort, 36.3% (n=45) of patients with anaemia were screened for IDA. Among those screened, 64.4% (n=29) had IDA. Only 17.2% (n=5) of these were treated with IV iron. After implementation of the quality improvement initiative, 90.9% (n=60) of patients with anaemia were screened for IDA (p<0.001) and 90.3% (n=28) of those with IDA were treated with IV iron (p<0.001). CONCLUSION The introduction of curated materials to aid clinicians was associated with increased rates of screening and treatment of IDA among ambulatory HFrEF patients. Further work is required to identify barriers and implement strategies to increase screening and treatment rates of IDA among HFrEF patients.

Abstract
Acute heart failure (HF) is associated with poor prognosis. After the acute event, there is a vulnerable period during which the patient has a marked risk of readmission or death. Therefore, early optimization of treatment is mandatory during the vulnerable period. The objective of this article is to provide recommendations to address the management of patients with HF during the vulnerable period from a practical point of view. A group of Mexican experts met to prepare a consensus document. The vulnerable period, with a duration of up to 6 months after the acute event - either hospitalization, visit to the emergency department or the outpatient clinic/day hospital - represents a real window of opportunity to improve outcomes for these patients. To best individualize the recommendations, the management strategies were divided into three periods (early, intermediate and late vulnerable period), including not only therapeutic options but also evaluation and education. Importantly, the recommendations are addressed to the entire cardiology team, including physicians and nurses, but also other specialists implicated in the management of these patients. In conclusion, this document represents an opportunity to improve the management of this population at high risk, with the aim of reducing the burden of HF.

Abstract
BACKGROUND Chronic heart failure (HF) is frequently associated with various comorbidities. These comorbid conditions, such as anemia, diabetes mellitus, renal insufficiency, and sleep apnea, can significantly impact the prognosis of patients with HF. OBJECTIVE This review aims to synthesize current evidence on the prevalence, impact, and management of comorbidities in patients with chronic HF. METHODS A comprehensive review was conducted, with a rigorous selection process. Out of an initial pool of 59,030 articles identified across various research modalities, 134 articles were chosen for inclusion. The selection spanned various research methods, from randomized controlled trials to observational studies. RESULTS Comorbidities are highly prevalent in patients with HF and contribute to increased hospitalization rates and mortality. Despite advances in therapies for HF with reduced ejection fraction, options for treating HF with preserved ejection fraction remain sparse. Existing treatment protocols often lack standardization, reflecting a limited understanding of the intricate relationships between HF and associated comorbidities. CONCLUSION There is a pressing need for a multidisciplinary, tailored approach to manage HF and its intricate comorbidities. This review underscores the importance of ongoing research efforts to devise targeted treatment strategies for HF patients with various comorbid conditions.

Abstract
OBJECTIVE We investigated the association of oral iron replacement with the incidence of chronic kidney disease (CKD) in a population with normal kidney function to study the effects of iron replacement on the development of new onset CKD. METHODS In a national cohort of US Veterans with no pre-existing CKD, we identified 33 894 incident new users of oral iron replacement and a comparable group of 112 780 patients who did not receive any iron replacement during 2004-2018. We examined the association of oral iron replacement versus no iron replacement with the incidence of eGFR <60 mL/min/1.73 m2 and the incidence of urine albumin creatinine ratio (UACR) ≥30 mg/g in competing risk regressions and in Cox models. We used propensity score weighing to account for differences in key baseline characteristics associated with the use of oral iron replacement. RESULTS In the cohort of 146 674 patients, a total of 18 547 (13%) patients experienced incident eGFR <60 mL/min/1.73 m2 , and 16 117 patients (11%) experienced new onset UACR ≥30 mg/g. Oral iron replacement was associated with significantly higher risk of incident eGFR <60 mL/min/1.73 m2 (subhazard ratio, 95% confidence interval [CI]: 1.3 [1.22-1.38], p < .001) and incident albuminuria (subhazard ratio, 95% CI: 1.14 [1.07-1.22], p < .001). CONCLUSION Oral iron replacement is associated with higher risk of new onset CKD. The long-term kidney safety of oral iron replacement should be tested in clinical trials.

Glimepiride, a novel soluble epoxide hydrolase inhibitor, protects against heart failure via increasing epoxyeicosatrienoic acids. J Mol Cell Cardiol 2023; 185:13-25.

Abstract
BACKGROUND Epoxyeicosatrienoic acids (EETs), which exert multiple endogenous protective effects, are hydrolyzed into less active dihydroxyeicosatrienoic acids (DHETs) by soluble epoxide hydrolase (sEH). However, commercial drugs related to EETs or sEH are not yet in clinical use. METHODS Firstly, the plasma concentration of EETs and DHETs of 316 patients with heart failure (HF) were detected and quantitated by liquid chromatography-tandem mass spectrometry. Then, transverse aortic constriction (TAC)-induced HF was introduced in cardiomyocyte-specific Ephx2-/- mice. Moreover, Western blot, real-time PCR, luciferase reporter, ChIP assays were employed to explore the underlying mechanism. Finally, multiple sEH inhibitors were designed, synthesized, and validated in vitro and in vivo. RESULTS The ratios of DHETs/EETs were increased in the plasma from patients with HF. Meanwhile, the expression of sEH was upregulated in the heart of patients and mice with HF, especially in cardiomyocytes. Cardiomyocyte-specific Ephx2-/- mice ameliorated cardiac dysfunction induced by TAC. Consistently, Ephx2 knockdown protected Angiotensin II (AngII)-treated cardiomyocytes via increasing EETs in vitro. Mechanistically, AngII could enhance the expression of transcript factor Krüppel-like factor 15 (KLF15), which in turn upregulated sEH. Importantly, glimepiride was identified as a novel sEH inhibitor, which benefited from the elevated EETs during HF. CONCLUSIONS Glimepiride attenuates HF in mice in part by increasing EETs.

Jankowska EA, Ponikowski P. Iron Deficiency in Heart Failure: A Korea-Oriented Review. INTERNATIONAL JOURNAL OF HEART FAILURE 2023; 5:173-183. [PMID: 37937204 PMCID: PMC10625879 DOI: 10.36628/ijhf.2023.0032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 08/24/2023] [Accepted: 09/27/2023] [Indexed: 11/09/2023]
Abstract
Iron deficiency (ID) occurs at high frequency across the spectrum of heart failure (HF), with HF severity and race being potentially important predictors for its development. ID, irrespective of anaemia status, leads to poor outcomes in patients with HF, including exacerbated reduction in exercise capacity, poor quality of life (QoL) and increased risk of HF hospitalisation. As ID has a large public health and economic burden in Asia, and patients hospitalised with acute HF in the Asia Pacific vs. other regions commonly present with more severe clinical symptoms, there is a clear need to identify and treat ID promptly in Asian patients with HF. The biomarkers serum ferritin and transferrin saturation are used for ID diagnosis, and periodic screening is recommended in all patients with HF. The intravenous iron treatments, ferric carboxymaltose (FCM) and ferric derisomaltose, have demonstrated efficacy and tolerability in patients with acute or chronic HF and ID, with FCM shown to be cost-effective (and in some cases cost-saving). Meta-analyses support the likely benefits of intravenous FCM for improving QoL and reducing HF hospitalisation, without reducing mortality risk in patients with HF and ID. Accordingly, European Society of Cardiology guidelines recommend considering intravenous FCM for patients with symptomatic HF with left ventricular ejection fraction ≤50% who were recently hospitalised for HF and have ID. Although analyses of Asian patients with HF and ID are limited, the effects of intravenous iron would be expected to be similar to that in White populations; further clarifying studies may be of interest.

Abstract
Background Iron deficiency (ID) has been shown to be a significant co-morbidity in patients with heart failure (HF), independent of their anaemia status. Correction of ID has been shown to improve quality of life, recurrent heart failure hospitalizations and morbidity. A quality improvement project was designed to improve the assessment and treatment of iron deficiency in HF patients in our tertiary care centre. Methods and results An initial baseline dataset was collected, followed by two cycles of interventions to help improve the care of HF patients admitted to our hospital over a two-month period. The Plan-Do-Study-Act (PDSA) cycle approach was applied, with the first intervention involving raising awareness of the importance and need to assess the iron status of HF patients through education provided to doctors, nurses and patients. Furthermore, information leaflets were produced and disseminated across the medical wards and through social media forums. The post-intervention datasets were collected and compared to the baseline outcomes. Baseline data showed that only four (20%) of heart failure patients had their iron status checked. Following the interventions, screening for ID increased to 80% (16), of which 85% (11) of those who identified as iron deficient received intravenous iron replacement. Conclusion The project was successful in improving the practice of screening for iron deficiency and intravenous replacement of iron in patients with HF.

Abstract
PURPOSE Intravenous iron therapy is recommended to improve symptoms and exercise tolerance in patients with heart failure (HF) with -reduced ejection fraction and iron deficiency (ID), but there are limited published data on the implementation of intravenous iron therapy in practice. A pharmacist-provider collaborative ID treatment clinic was established within an advanced HF and pulmonary hypertension service to optimize IV iron therapy. The objective was to evaluate the clinical impacts of the pharmacist-provider collaborative ID treatment clinic. METHODS A retrospective cohort study was performed to compare clinical outcomes among patients of the collaborative ID treatment clinic (the postimplementation group) and a cohort of patients who received usual care (the preimplementation group). The study included patients 18 years of age or older with diagnosed HF or pulmonary hypertension who met prespecified criteria for ID. The primary outcome was adherence to institutional intravenous iron therapy guidance. A key secondary outcome was ID treatment goal achievement. RESULTS A total of 42 patients in the preimplementation group and 81 in the postimplementation group were included in the study. The rate of adherence to the institutional guidance was significantly improved in the postimplementation group (93%) compared to the preimplementation group (40%). There was no significant difference in the ID therapeutic target achievement rate between the pre- and postimplementation groups (38% vs 48%). CONCLUSION Implementing a pharmacist-provider collaborative ID treatment clinic significantly increased the number of patients who adhered to intravenous iron therapy guidance compared to usual care.

Impact of comorbidities on health status measured using the Kansas City Cardiomyopathy Questionnaire in patients with heart failure with reduced and preserved ejection fraction. Eur J Heart Fail 2023; 25:1606-1618. [PMID: 37401511 DOI: 10.1002/ejhf.2962] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 06/18/2023] [Accepted: 06/28/2023] [Indexed: 07/05/2023] Open
Abstract
AIM Patients with heart failure (HF) often suffer from a range of comorbidities, which may affect their health status. The aim of this study was to assess the impact of different comorbidities on health status in patients with HF and reduced (HFrEF) and preserved ejection fraction (HFpEF). METHODS AND RESULTS Using individual patient data from HFrEF (ATMOSPHERE, PARADIGM-HF, DAPA-HF) and HFpEF (TOPCAT, PARAGON-HF) trials, we examined the Kansas City Cardiomyopathy Questionnaire (KCCQ) domain scores and overall summary score (KCCQ-OSS) across a range of cardiorespiratory (angina, atrial fibrillation [AF], stroke, chronic obstructive pulmonary disease [COPD]) and other comorbidities (obesity, diabetes, chronic kidney disease [CKD], anaemia). Of patients with HFrEF (n = 20 159), 36.2% had AF, 33.9% CKD, 33.9% diabetes, 31.4% obesity, 25.5% angina, 12.2% COPD, 8.4% stroke, and 4.4% anaemia; the corresponding proportions in HFpEF (n = 6563) were: 54.0% AF, 48.7% CKD, 43.4% diabetes, 53.3% obesity, 28.6% angina, 14.7% COPD, 10.2% stroke, and 6.5% anaemia. HFpEF patients had lower KCCQ domain scores and KCCQ-OSS (67.8 vs. 71.3) than HFrEF patients. Physical limitations, social limitations and quality of life domains were reduced more than symptom frequency and symptom burden domains. In both HFrEF and HFpEF, COPD, angina, anaemia, and obesity were associated with the lowest scores. An increasing number of comorbidities was associated with decreasing scores (e.g. KCCQ-OSS 0 vs. ≥4 comorbidities: HFrEF 76.8 vs. 66.4; HFpEF 73.7 vs. 65.2). CONCLUSIONS Cardiac and non-cardiac comorbidities are common in both HFrEF and HFpEF patients and most are associated with reductions in health status although the impact varied among comorbidities, by the number of comorbidities, and by HF phenotype. Treating/correcting comorbidity is a therapeutic approach that may improve the health status of patients with HF.

Abstract
Iron deficiency is an independent risk factor for heart failure (HF) exacerbation. We aim to study the safety and efficacy of intravenous (IV) iron therapy in patients with HF with reduced ejection fraction (HFrEF). A literature search was conducted on MEDLINE (Embase and PubMed) using a systematic search strategy by PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) until October 2022. CRAN-R software (The R Foundation for Statistical Computing, Vienna, Austria) was used for statistical analysis. The quality assessment was performed using the Cochrane Risk of Bias and Newcastle-Ottawa Scale. We included 12 studies with a total of 4,376 patients (IV iron n = 1,985 [45.3%]; standard of care [SOC] n = 2,391 [54.6%]). The mean age was 70.37 ± 8.14 years and 71.75 ± 7.01 years in the IV iron and SOC groups, respectively. There was no significant difference in all-cause mortality and cardiovascular mortality (risk ratio [RR] 0.88, 95% confidence interval [CI] 0.74 to 1.04, p <0.15). However, HF readmissions were significantly lower in the IV iron group (RR 0.73, 95% CI 0.56 to 0.96, p = 0.026). Non-HF cardiac readmissions were not significantly different between the IV iron and SOC groups (RR 0.92, 95% CI 0.82 to 1.02, p = 0.12). In terms of safety, there was a similar rate of infection-related adverse events in both arms (RR 0.86, 95% CI 0.74 to 1, p = 0.05). IV iron therapy in patients with HFrEF is safe and shows a significant reduction in HF hospitalizations compared with SOC. There was no difference in the rate of infection-related adverse events. The changing landscape of HFrEF pharmacotherapy in the last decade may warrant a re-demonstration of the benefit of IV iron with current SOC. The cost-effectiveness of IV iron use also needs further study.

Abstract
Anemia is a common complication of chronic kidney disease (CKD) and is associated with a decrease in quality of life and an increased risk of transfusions, morbidity and mortality, and progression of CKD. The Anemia Working Group of the Sociedad Española de Nefrología conducted a Delphi study among experts in anemia in CKD to agree on relevant unanswered questions by existing evidence. The RAND/UCLA consensus methodology was used. We defined 15 questions with a PICO structure, followed by a review in scientific literature databases. Statements to each question were developed based on that literature review. Nineteen experts evaluated them using an iterative Two-Round Delphi-like process. Sixteen statements were agreed in response to 8 questions related to iron deficiency and supplementation with Fe (impact and management of iron deficiency with or without anemia, iron deficiency markers, safety of i.v. iron) and 7 related to erythropoiesis stimulating agents (ESAs) and/or hypoxia-inducible factor stabilizers (HIF), reaching consensus on all of them (individualization of the Hb objective, impact and management of resistance to ESA, ESA in the immediate post-transplant period and HIF stabilizers: impact on ferrokinetics, interaction with inflammation and cardiovascular safety). There is a need for clinical studies addressing the effects of correction of iron deficiency independently of anemia and the impact of anemia treatment with various ESA on quality of life, progression of CKD and cardiovascular events.

Abstract
BACKGROUND Reduced kidney function is common among patients with heart failure. In patients with heart failure and/or kidney disease, iron deficiency is an independent predictor of adverse outcomes. In the AFFIRM-AHF trial, patients with acute heart failure with iron deficiency treated with intravenous ferric carboxymaltose demonstrated reduced risk of heart failure hospitalization, with improved quality of life. We aimed to further characterize the impact of ferric carboxymaltose among patients with coexisting kidney impairment. METHODS The double-blind, placebo-controlled AFFIRM-AHF trial randomized 1132 stabilized adults with acute heart failure (left ventricular ejection fraction <50%) and iron deficiency. Patients on dialysis were excluded. The primary end point was a composite of total heart failure hospitalizations and cardiovascular death during the 52-week follow-up period. Additional end points included cardiovascular hospitalizations, total heart failure hospitalizations, and days lost to heart failure hospitalizations or cardiovascular death. For this subgroup analysis, patients were stratified according to baseline eGFR. RESULTS Overall, 60% of patients had an eGFR <60 ml/min per 1.73 m 2 (the lower eGFR subgroup). These patients were significantly older, more likely to be female and to have ischemic heart failure, and had higher baseline serum phosphate levels and higher rates of anemia. For all end points, event rates were higher in the lower eGFR group. In the lower eGFR group, the annualized event rates for the primary composite outcome were 68.96 and 86.30 per 100 patient-years in the ferric carboxymaltose and placebo arms, respectively (rate ratio, 0.76; 95% confidence interval, 0.54 to 1.06). The treatment effect was similar in the higher eGFR subgroup (rate ratio, 0.65; 95% confidence interval, 0.42 to 1.02; Pinteraction = 0.60). A similar pattern was observed for all end points ( Pinteraction > 0.05). CONCLUSIONS In a cohort of patients with acute heart failure, left ventricular ejection fraction <50%, and iron deficiency, the safety and efficacy of ferric carboxymaltose were consistent across a range of eGFR values.

Abstract
AIMS Iron deficiency (ID) is common in heart failure (HF) and linked with poor prognosis regardless of anaemia. We assessed temporal trends in ID testing, ID prevalence, ID incidence, iron need, and outcomes associated with ID in HF across the ejection fraction (EF) spectrum. METHODS AND RESULTS From the Swedish HF registry, we enrolled 15 197 patients from Region Stockholm with available EF and collected laboratory tests from routine practice. Iron screening improved since 2016 but remained <25% as of 2018. In 1486 patients with iron biomarkers at baseline, the prevalence of ID was 55% (HF with reduced EF 54%; mildly reduced EF 51%; preserved EF 61%). Iron need was ≥1500 mg in 72% of patients. ID was independently associated with higher risk for HF rehospitalizations (incidence rate ratio [IRR] 1.62, 95% confidence interval [CI] 1.13-2.31) and with cardiovascular (CV) death or repeated HF hospitalizations (IRR 1.63, 95% CI 1.15-2.30) regardless of EF (p-interaction 0.21 and 0.26, respectively), but not with all-cause death, CV death, or first HF hospitalization. Among 96 patients without ID at baseline and with follow-up iron biomarkers, 21% developed ID within 6 months. CONCLUSIONS Iron deficiency screening improved over time but is still limitedly implemented, despite being highly prevalent and incident, and independently associated with CV death or HF rehospitalizations regardless of EF. Most patients with ID had an iron need necessitating either repeated administrations of intravenous iron or a preparation permitting >1000 mg doses. These data highlight the need for improved screening for ID in HF.

Abstract
PURPOSE OF REVIEW Iron deficiency (ID) complicates heart failure (HF) at different stages of the natural history of the disease; however, this frequent comorbidity is still not comprehensively understood and investigated in terms of pathophysiology. Intravenous iron therapy with ferric carboxymaltose (FCM) should be considered to improve the quality of life, exercise capacity, and symptoms in stable HF with ID, as well as to reduce HF hospitalizations in iron-deficient patients stabilized after an episode of acute HF. The therapy with intravenous iron, however, continues to generate important clinical questions for cardiologists. RECENT FINDINGS In the current paper, we discuss the class effect concept for intravenous iron formulations beyond FCM, based on the experiences of nephrologists who administer different intravenous iron formulations in advanced chronic kidney disease complicated with ID and anemia. Furthermore, we discuss the neutral effects of oral iron therapy in patients with HF, because there are still some reasons to further explore this route of supplementation. The different definitions of ID applied in HF studies and new doubts regarding possible interactions of intravenous iron with sodium-glucose co-transporter type 2 inhibitors are also emphasized. The experiences of other medical specializations may provide new information on how to optimally replenish iron in patients with HF and ID.

BACKGROUND Iron deficiency (ID) is a common comorbidity among patients with heart failure and reduced ejection fraction (HFrEF), and is associated with poorer outcomes independent of anemia. This study aimed to evaluate the prevalence and prognostic significance of ID in Taiwanese patients with HFrEF. METHODS We included HFrEF patients from two multicenter cohorts at different periods. The multivariate Cox regression analysis was applied to assess the risk of outcomes associated with ID, accounting for the varying risk of death. RESULTS Of the 3612 patients with HFrEF registered from 2013 to 2018, 665 patients (18.4%) had available baseline iron profile measurements. Of these, 290 patients (43.6%) were iron deficient; 20.2% had ID+/anemia+, 23.4% ID+/anemia-, 21.5% ID-/anemia+, and 34.9% ID-/anemia-. Regardless of anemia status, patients with coexisting ID had a higher risk than those without ID (all-cause mortality: 14.3 vs 9.5 per 100 patient-years, adjusted hazard ratio [HR] 1.33; 95% confidence interval [CI], 0.96-1.85; p = 0.091; cardiovascular mortality: 10.5 per 100 patient-years vs 6.1, adjusted HR 1.54 [95% CI, 1.03-2.30; p = 0.037]; cardiovascular mortality or first unplanned hospitalization for HF: 36.7 vs 19.7 per 100 patient-years, adjusted HR 1.57 [95% CI, 1.22-2.01; p < 0.001]). Among patients eligible for treatment in the IRONMAN trial design (43.9%), parenteral iron therapy was estimated to reduce heart failure hospitalizations and cardiovascular deaths by 13.7 per 100 patient-years. CONCLUSION Iron profiles were tested in less than one-fifth of the Taiwanese HFrEF cohort. ID was present in 43.6% of tested patients and was independently associated with poor prognosis in these patients.

Abstract
This review examines the pharmacotherapy and lifestyle recommendations of the most recent iterations of the Canadian Cardiovascular Society (CCS) / Canadian Heart Failure Society (CHFS), the European Society of Cardiology (ESC), and the American Heart Association (AHA) / American College of Cardiology (ACC) / Heart Failure Society of America (HFSA) heart failure (HF) guidelines, which all have been updated in response to therapeutic developments across the spectrum of left ventricular ejection fraction. Identified areas of unanimity across these guidelines include the following: recommending quadruple therapy for patients with HF with reduced ejection fraction (HFrEF; although no guideline proposed an ideal sequence of initiation); intravenous iron administration for patients with HFrEF and iron deficiency; and sodium restriction for patients with HF. Recent evidence regarding the harms of HFrEF medication withdrawal in patients with HF with improved ejection fraction has prompted subsequent guidelines to recommend against withdrawal. Due to the lower quality of evidence, there are disagreements regarding management of HF with preserved ejection fraction and uncertainty regarding management of HF with mildly reduced ejection fraction. Practical guidance is provided to clinicians navigating these challenging areas. In addition to these clinically focused comparisons, we describe opportunities for guideline improvement and harmonization. Specifically, these include opportunities regarding HFrEF sequencing, the need for timely updates, shared decision-making, Grading of Recommendations, Assessment, Development and Evaluations (GRADE) framework adoption, and the creation of recommendations where high-quality evidence is lacking. Although these guidelines have broad agreement, key areas of controversy remain that may be addressed by emerging evidence and changes in guideline methodology.

Abstract
Iron deficiency is present in approximately 50% of patients with symptomatic heart failure and is independently associated with worse functional capacity, lower quality of, life and increased mortality. The purpose of this document is to summarize current knowledge of how iron deficiency is defined in heart failure and its epidemiology and pathophysiology, as well as pharmacological considerations for repletion strategies. This document also summarizes the rapidly expanding array of clinical trial evidence informing when, how, and in whom to consider iron repletion.

Abstract
PURPOSE OF REVIEW Heart failure (HF) is commonly associated with iron deficiency (ID), defined as insufficient levels of iron to meet physiological demands. ID's association with anaemia is well understood but it is increasingly recognised as an important comorbidity in HF, even in the absence of anaemia. This review summarises contemporary evidence for the measurement and treatment of ID, in both HFrEF and HFpEF, and specific HF aetiologies, and highlights important gaps in the evidence-base. RECENT FINDINGS ID is common among patients with HF and associated with increased morbidity and mortality. Correcting ID in patients with HF can impact upon functional status, exercise tolerance, symptoms, and overall quality of life, irrespective of anaemia status. ID is a modifiable comorbidity in HF. Therefore, recognising and treating ID has emerging therapeutic potential and is important for all clinicians who care for patients with HF to understand the rationale and approach to treatment.

Abstract
Background Randomized clinical trials (RCTs) evaluating the role of intravenous (IV) iron administration in patients with heart failure (HF) and iron deficiency (ID) have yielded inconsistent results. Methods Electronic search of MEDLINE, EMBASE and OVID databases was performed until November 2022 for RCTs that evaluated the role of IV iron administration in patients with HF and ID. The main study outcomes were the composite of HF hospitalization or cardiovascular mortality, and individual outcome of HF hospitalization. Summary estimates were evaluated using random effects model. Results The final analysis included 12 RCTs with 3,492 patients (1,831 patients in the IV iron group and 1,661 patients in the control group). The mean follow-up was 8.3 months. IV iron was associated with a lower incidence in the composite of HF hospitalization or cardiovascular mortality (31.9% vs. 45.3%; relative risk [RR] 0.72; 95% confidence interval [CI] 0.59-0.88) and individual outcome of HF hospitalization (28.4% vs. 42.2; RR 0.69; 95% CI 0.57-0.85). There was no significant difference between both groups in cardiovascular mortality (RR 0.88; 95% CI 0.75-1.04) and all-cause mortality (RR 0.95; 95% CI 0.83-1.09). IV iron was associated with lower New York Heart Association class and higher left ventricular ejection fraction (LVEF). Meta-regression analyses showed no effect modification for the main outcomes based on age, hemoglobin level, ferritin level or LVEF. Conclusion Among patients with HF and ID, IV iron administration was associated with reduction in the composite of HF hospitalization or cardiovascular mortality and driven by a reduction in HF hospitalization.

Abstract
The timely correction of anaemia before major surgery is important for optimising perioperative patient outcomes. However, multiple barriers have precluded the global expansion of preoperative anaemia treatment programmes, including misconceptions about the true cost/benefit ratio for patient care and health system economics. Institutional investment and buy-in from stakeholders could lead to significant cost savings through avoided complications of anaemia and red blood cell transfusions, and through containment of direct and variable costs of blood bank laboratories. In some health systems, billing for iron infusions could generate revenue and promote growth of treatment programmes. The aim of this work is to galvanise integrated health systems worldwide to diagnose and treat anaemia before major surgery.

Abstract
Heart failure (HF) is one of the most common causes of death in industrialized countries and increases steadily with age. Patients with HF present many comorbidities that affect their clinical management, quality of life, and prognosis. Iron deficiency is a relevant comorbidity of all patients with heart failure. It remains the most prevalent nutritional deficiency worldwide, affecting an estimated 2 billion people and has a negative prognostic impact on hospitalization and mortality rate. To date, none of the previous studies, have provided evidence of reduced mortality or decrease in hospitalization with intravenous iron supplementation. This review describes the prevalence, clinical implications, and current trials on the treatment of iron deficiency in heart failure and discusses the Improvement of exercise and functional capacity and quality of life in patients with heart failure by iron therapy. Despite compelling evidence of the significant prevalence of ID in HF patients and current guidelines, ID is often not properly managed in clinical practice. Therefore, ID should be given greater consideration in HF health care practice to improve patient quality of life and outcome.

Abstract
Iron is an essential micronutrient for several physiological processes in the body beyond erythropoiesis. Iron deficiency (ID) is a common comorbidity observed in about 50% of patients with stable heart failure (HF) irrespective of the left ventricular function. The presence of ID is often as a multi-factorial condition, and it is associated with exercise intolerance, reduced quality of life, increased hospitalization rate, and mortality risk regardless of anaemia. The intravenous administration of iron to correct ID has emerged as a promising treatment in HF with reduced ejection fraction as it has been shown to alleviate symptoms, improve quality of life and exercise capacity, and reduce hospitalizations.

Abstract
BACKGROUND This study aims to analyse whether in acute heart failure (AHF) with iron deficiency (ID), the administration of ferric carboxymaltose (FCM) produces a greater benefit in renal dysfunction. METHODS A total of 812 consecutive patients admitted for AHF and ID were studied. Untreated (n:272) and treated (n:540) patients were compared. The six-month prevalence of a combined event (readmission for HF, all-cause death, and emergency department visit for decompensation) was analysed. Three grades of renal dysfunction (KDIGO) were compared, Group 1 (grades 1 and 2), Group 2 (grades 3a and 3b), and Group 3 (grades 4 and 5). RESULTS There were differences in sex distribution (untreated group: males 39.7% vs. treated group: males 51.9%; p < 0.001). Sex-adjusted combined event analysis showed a greater benefit in Group 1 (OR: 0.31, 95% CI:0.19-0.5; p < 0.001) and Group 2 (OR: 0.23, 95% CI:0.14-0.38; p < 0.001), but not in Group 3 (OR: 0.51, 95% CI:0.17-0.55; p: 0.237). CONCLUSIONS The administration of FCM in patients with AHF and ID reduces the combined event analysed. The benefit is greater when renal dysfunction is present, except in very advanced degrees where no significant benefit is obtained.

Abstract
The coronavirus disease (COVID-19) outbreak affected the utilization and management of blood products in hospitals. Blood shortages occurred owing to social distancing policies and reduction in blood donors. However, only a few studies examined whether these changes affected blood usage and transfusion patterns. We retrospectively reviewed blood component usage according to hospital departments and phases of surgery in transfused patients admitted between 1 March 2019 and 28 February 2021, in a single center in Anyang, Korea. We also analyzed the length of hospital stay and mortality to determine prognosis. In 2020, 32,050 blood components were transfused to 2877 patients, corresponding to 15.8% and 11.8% less than the rates in 2019, respectively. Postoperative usage of blood products significantly decreased in 2020 (3.87 ± 6.50) compared to 2019 (7.12 ± 21.71) (p = 0.047). The length of hospital stay of the patients who underwent postoperative transfusion in 2019 (n = 197) was 13.97 ± 11.95 days, which was not significantly different from that in 2020 (n = 167), i.e., 16.44 ± 17.90 days (p = 0.118). Further, 9 of 197 postoperative transfusion patients died in 2019, while 8 of 167 patients died in 2020 (p = 0.920). The COVID-19 pandemic resulted in limited blood supply and reduced postoperative transfusions; however, patient prognosis was not affected.

Abstract
The cardiovascular system requires iron to maintain its high energy demands and metabolic activity. Iron plays a critical role in oxygen transport and storage, mitochondrial function, and enzyme activity. However, excess iron is also cardiotoxic due to its ability to catalyze the formation of reactive oxygen species and promote oxidative damage. While mammalian cells have several redundant iron import mechanisms, they are equipped with a single iron-exporting protein, which makes the cardiovascular system particularly sensitive to iron overload. As a result, iron levels are tightly regulated at many levels to maintain homeostasis. Iron dysregulation ranges from iron deficiency to iron overload and is seen in many types of cardiovascular disease, including heart failure, myocardial infarction, anthracycline-induced cardiotoxicity, and Friedreich's ataxia. Recently, the use of intravenous iron therapy has been advocated in patients with heart failure and certain criteria for iron deficiency. Here, we provide an overview of systemic and cellular iron homeostasis in the context of cardiovascular physiology, iron deficiency, and iron overload in cardiovascular disease, current therapeutic strategies, and future perspectives.

Abstract
Heart failure (HF) is a complex syndrome that affects mortality/morbidity and acts at different levels in the patient's life, resulting in a drastic impairment in multiple aspects of daily activities (e.g. physical, mental/emotional, and social) and leading to a reduction in quality of life. The definition of disease status and symptom severity has been traditionally based on the physician assessment, while the patient's experience of disease has been long overlooked. The active participation of patients in their own care is necessary to better understand the perception of disease and the multiple aspects of life affected, and to improve adherence to treatments. Patient-reported outcomes (PROs) aim to switch traditional care to a more patient-centred approach. Although PROs demonstrated precision in the evaluation of disease status and have a good association with prognosis in several randomized controlled trials, their implementation into clinical practice is limited. This review discusses the modalities of use of PROs in HF, summarizes the most largely adopted PROs in HF care, and provides an overview on the application of PROs in trials and the potential for their transition to clinical practice. By discussing the advantages and the disadvantages of their use, the reasons limiting their application in daily clinical routine, and the strategies that may promote their implementation, this review aims to foster the systematic integration of the patient's standpoint in HF care.

Trends and Predictors of Poor Outcomes in Patients With Right Heart Failure: Insights From the National Readmission Database. Curr Probl Cardiol 2023; 48:101625. [PMID: 36724819 DOI: 10.1016/j.cpcardiol.2023.101625] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Accepted: 01/23/2023] [Indexed: 01/30/2023]
Abstract
Right heart failure (RHF) is a complex clinical syndrome that confers high risk of morbidity and mortality. We sought to study RHF using large national database. The study is a retrospective analysis of the National Readmission Database (NRD) of years 2017-2019. Admissions with a primary diagnosis of RHF were included. Study outcomes were temporal trends of RHF diagnosis and predictors of in-hospital mortality and 30-day readmission. Subgroup analysis according to co-presence of reduced or preserved left ventricular ejection fraction (LVEF). Multivariate logistic regression was utilized to detect predictors of poor outcome and difference between subgroups. A total of 127,503 admissions were identified from the database of which 4,717 primary RHF admissions were included in our cohort. There was a trend of increasing RHF diagnosis from 2017 4th Quarter to 2019 4th Quarter. Age, liver disease and reduced LVEF were amongst predictors of in-hospital mortality while iron deficiency anemia and a Charlson Comorbidity Score ≥ 3 were predictors of 30-day readmission. The study of real-world data contributes to a better understanding of RHF outcomes. Further studies are needed to investigate the association between RHF and different types of heart failure and its implications on clinical practice.

Multicomponent intervention for frail and pre-frail older adults with acute cardiovascular conditions: The TARGET-EFT randomized clinical trial. J Am Geriatr Soc 2023; 71:1406-1415. [PMID: 36645227 DOI: 10.1111/jgs.18228] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 12/06/2022] [Accepted: 12/18/2022] [Indexed: 01/17/2023]
Abstract
BACKGROUND Hospitalization for cardiovascular disease (CVD) may be complicated by hospital-acquired disability (HAD) and subsequently poor health-related quality of life (HRQOL). While frailty has been shown to be a risk factor, it has yet to be studied as a therapeutic target to improve outcomes. OBJECTIVES This trial sought to determine the effects of an in-hospital multicomponent intervention targeting physical weakness, cognitive impairment, malnutrition, and anemia on patient-centered outcomes compared to usual care. METHODS A single-center parallel-group randomized clinical trial was conducted in older patients with acute CVD and evidence of frailty or pre-frailty as measured by the Essential Frailty Toolset (EFT). Patients were randomized to usual care or a multicomponent intervention. Outcomes were HRQOL (EQ-5D-5L score) and disability (Older Americans Resources and Services score) at 30 days post-discharge and mood disturbances (Hospital Anxiety and Depression Scale) at discharge. RESULTS The trial cohort consisted of 142 patients with a mean age of 79.5 years and 55% females. The primary diagnosis was heart failure in 29%, valvular heart disease in 28%, ischemic heart disease in 14%, arrhythmia in 11%, and other CVDs in 18%. The intervention improved HRQOL scores (coefficient 0.08; 95% CI 0.01, 0.15; p = 0.03) and mood scores (coefficient -1.95; 95% CI -3.82, -0.09; p = 0.04) but not disability scores (coefficient 0.18; 95% CI -1.44, 1.81; p = 0.82). There were no intervention-related adverse events. CONCLUSION In frail older patients hospitalized for acute CVDs, an in-hospital multicomponent intervention targeted to frailty was safe and led to modest yet clinically meaningful improvements in HRQOL and mental well-being. The downstream impact of these effects on event-free survival and functional status remains to be evaluated in future research, as does the generalizability to other healthcare systems. CLINICAL REGISTRATION NUMBER NCT04291690.

Abstract
Cardiac cachexia is a muscle wasting process that often develops in those with chronic heart failure resulting in weight loss, low levels of physical activity, reduced quality of life, and is associated with a poor prognosis. The pathology of cardiac cachexia is complex with new evidence emerging that implicates several body systems. This review describes the pathophysiology associated with cardiac cachexia and addresses: 1) hormonal changes- neurohormonal abnormalities and metabolic hormone imbalance; 2) mechanisms of muscle wasting in cardiac cachexia, and the integral mechanisms between changed hormones due to cardiac cachexia and muscle wasting processes, and 3) associated abnormalities of gastrointestinal system that contribute to cardiac cachexia. These pleiotropic mechanisms demonstrate the intricate interplay between the affected systems and account for why cardiac cachexia is difficult to manage clinically. This review summarises current pathophysiology of cardiac cachexia and highlights symptoms of cardiac cachexia, implications for clinical practice and research gaps.

Abstract
In addition to drug therapy, lifestyle modification, including physical activity, and nutrition management are an integral part of current guidelines for patients with chronic heart failure (CHF). However, evidence on which clinical parameters are most influenced by nutritional behaviour, exercise capacity, or iron status is scarce. For a multicenter intervention study, we included participants with diagnosed CHF (n = 165) as well as participants with elevated NT-proBNP values and risk factors for CHF (n = 74). Cardiorespiratory fitness was tested with a bicycle test, and adherence to the Mediterranean diet (MedDiet) was assessed with the MDS questionnaire. Our data strengthened previous results confirming that the higher a person's adherence to MedDiet, the higher the cardiorespiratory fitness and the lower the body fat. Furthermore, our results showed that anemia in patients with CHF has an impact in terms of cardiorespiratory fitness, and functional outcomes by questionnaire. Since our data revealed gaps in iron supply (37.9% with iron deficiency), malnutrition (only 7.8% with high adherence to MedDiet), and both symptomatic and non-symptomatic study participants failed to meet reference values for physical performance, we encourage the enforcement of the guidelines in the treatment of CHF more strongly.

Abstract
Among different pathomechanisms involved in the development of heart failure, adverse metabolic myocardial remodeling closely related to ineffective energy production, constitutes the fundamental feature of the disease and translates into further progression of both cardiac dysfunction and maladaptations occurring within other organs. Being the component of key enzymatic machineries, iron plays a vital role in energy generation and utilization, hence the interest in whether, by correcting systemic and/or cellular deficiency of this micronutrient, we can influence the energetic efficiency of tissues, including the heart. In this review we summarize current knowledge on disturbed energy metabolism in failing hearts as well as we analyze experimental evidence linking iron deficiency with deranged myocardial energetics.

Abstract
Iron interactions with the cardiovascular system were proposed about half a century ago, yet a clear-cut understanding of this micronutrient and its intricacies with acute and chronic events is still lacking. In chronic heart failure, patients with decreased iron stores appear to benefit from intravenous administration of metallic formulations, whereas acute diseases (e.g., myocardial infarction, stroke) are barely studied in randomized controlled trials in humans. However, proof-of-concept studies have indicated that the dual redox characteristics of iron could be involved in atherosclerosis, necrosis, and ferroptosis. To this end, we sought to review the currently available body of literature pertaining to these temporal profiles of heart diseases, as well as the pathophysiologic mechanism by which iron enacts, underlining key points related to treatment options.

Abstract
ABSTRACT Iron deficiency is common in patients with heart failure and has been associated with worse outcomes, including increases in mortality, disease progression, and hospitalizations. As such, several studies have evaluated the role of iron supplementation in mitigating these risks. Evidence for the role of intravenous iron in improving exercise capacity, quality of life, and hospitalizations is promising, although the benefits of oral iron remain less clear. This review will evaluate the literature surrounding iron supplementation in heart failure and provide practical recommendations for its management.

Abstract
Hospitalizations for heart failure (HF) have become a global problem worldwide. Each episode of HF decompensation may lead to deleterious short- and long- term consequences, but on the other hand is an unique opportunity to adjust the heart failure pharmacotherapy. Thus, in-hospital and an early post-discharge period comprise an optimal timing for initiation and optimization of the comprehensive management of HF. This timeframe affords clinicians an opportunity to up titrate and adjust guideline-directed medical therapies (GDMT) to potentially mitigate poor outcomes associated post-discharge and longer-term. This review will cover this timely concept, present the data of utilization of GDMT in HF populations, discuss recent evidence for in-hospital initiation and up-titration of GDMT with a need for post-discharge follow-up and implementation this into clinical practice in patients with heart failure and reduced ejection fraction.

Abstract
AIMS This review aimed to assess whether oral iron supplementation in a chronic heart failure (HF) population with iron deficiency (ID) or mild anaemia is safe and effective according to evidence-based medicine. METHODS We retrieved 1803 records from the PubMed, Embase, and the Cochrane Library databases from 1 January 1991 to 15 September 2021. The clinical outcome of oral iron supplementation for ID anaemia in patients with HF was the primary endpoint. The primary safety measures included adverse events and all-cause mortality, and efficacy measures included transferrin saturation (Tsat), ferritin levels, and the 6-min walk test (6MWT). The rate ratio (RR) was used to pool the efficacy measures. RESULTS Five randomized controlled trials that compared oral iron treatment for patients with the placebo group and included a combined total of 590 participants were analysed. No significant difference was found in all-cause death between oral iron treatment and placebo groups (RR = 0.77; 95% confidence intervals (CI), 0.46-1.29, Z = 0.98; P = 0.33). However, adverse events were not significantly higher in the iron treatment group (RR = 0.83; 95% CI, 0.60-1.16, Z = 1.07; P = 0.28). In addition, ferritin levels and Tsat were slightly increased after iron complex administration in patients with HF but were not statistically significant (ferritin: mean difference [MD] = 2.70, 95% CI, -2.41 to 7.81, Z = 1.04; P = 0.30; Tsat: MD = 27.42, 95% CI, -4.93 to 59.78, Z = 1.66; P = 0.10). No significant difference was found in exercise capacity, as indicated by the 6MWT results (MD = 59.60, 95% CI, -17.89 to 137.08, Z = 1.51; P = 0.13). We also analysed two non-randomized controlled trials with follow-up results showing that oral iron supplementation increased serum iron levels (MD = 28.87, 95% CI, 1.62-56.12, Z = 2.08; P = 0.04). CONCLUSIONS Based on the current findings, oral iron supplementation can increase serum iron levels in patients with HF and ID or mild anaemia but does not improve Tsat and 6MWT. In addition, oral iron supplementation is relatively safe.
