AIM: To discuss the pathophysiology of iron metabolism in chronic heart failure (CHF), the current knowledge of the efficacy of intravenous (IV) iron therapy in patients with CHF and identify points of controversy as well as highlight areas for future research. DISCUSSION: Iron deficiency is a recognised complication of many chronic conditions. Numerous studies have reported that iron deficiency is highly prevalent in patients with CHF and is associated with exercise intolerance, reduced quality of life, and increased risk of hospitalisation and mortality...

Iron deficiency is a prevalent and clinically relevant comorbidity in up to 50% of patients with chronic heart failure (CHF). Iron deficiency in CHF patients is associated with impaired quality of life, reduced exercise capacity and increased mortality, irrespective of the presence of anaemia. It is diagnosed by determining circulating ferritin levels and transferrin saturation. Three randomised trials (CONFIRM-HF, FAIR-HF, and EFFECT-HF) of intravenous ferric carboxymaltose in the treatment of iron deficiency in CHF patients with reduced left ventricular ejection fraction demonstrated improvement of symptoms, functional capacity and quality of life...

AIMS: To define iron deficiency in chronic heart failure (CHF), both, ferritin<100μg/L (indicating reduced iron storage) and transferrin saturation (TSAT)<20% (indicating reduced iron transport) are used. The aim of the study was to evaluate clinical outcomes and prognosis of either low ferritin or low TSAT in patients with CHF. METHODS AND RESULTS: We evaluated the clinical impact of impaired iron storage (IIS) and impaired iron transport (IIT) either alone or in combination compared to patients with normal iron status (NIS), in an international cohort of 1821 patients with CHF with a mean age of 66±13years and mean left ventricular ejection fraction of 35%±15...

Ami Belmont, Janet L Kwiatkowski
Transfusional iron overload can lead to hepatic fibrosis, arrhythmias and congestive heart failure and a number of endocrinopathies. Deferiprone is an oral iron chelator approved for use in the United States as a second line agent for the treatment of transfusional iron overload in patients with thalassemia. Areas covered: This article will review the data regarding the efficacy of deferiprone for iron chelation and prevention and reversal of iron related complications, the drug's adverse effect profile, and the use of this drug in combination regimens...

Eisenmenger syndrome (ES) is the most severe form of pulmonary arterial hypertension (PAH) associated with congenital heart disease. It is an extremely devastating condition with a serious impact on patients' life. Classical therapy of ES remains directed to avoid complications, such as erythrocytosis, treatment of congestive heart failure, prevention of infection, and secondary haematological abnormalities such as iron deficiency and coagulation disorders. However, the only effective treatment is heart-lung transplantation; still, morbidity and mortality after transplantation remain substantially high...

Epirubicin (EPI) is one of the most widely used anticarcinogens; however, serious side effects, including cardiomyopathy and congestive heart failure, limit its long‑term administration. To overcome this problem, the HAIYPRH peptide ligand was used with EPI in the synthesis of a HAIYPRH‑EPI conjugate. The anticancer activity and cellular uptake of the conjugate were measured and evaluated. The results of the present study indicated that the cytotoxicity of HAIYPRH‑EPI was correlated with the expression of the cell surface transferrin receptor (TfR)...

The blue glow of the mucus from Chaetopterus involves a photoprotein, iron and flavins. Identity and respective role of these components remain, however, largely unresolved today, likely because of viscosity issues and inhibition of this system by oxidizers conventionally used to track bioluminescence activity. Here, we used gentle centrifugation to obtain a mucus supernatant showing no inhibition to oxidizers, allowing for further analysis. We applied conventional chromatographic techniques to isolate major proteins associated with light emission...

Anemia is an independent risk factor for adverse patient outcomes. There are no guidelines for management of anemia in patients with congestive heart failure (CHF), despite its high incidence. Four objectives were defined by the International Anemia Management and Clinical Outcomes Expert Panel (AMCO), a multinational group of interdisciplinary experts identified by the Society for the Advancement of Blood Management (SABM) to: determine the prevalence of anemia in outpatients; to determine the prevalence of hospital-acquired anemia; to assess the impact of anemia management on clinical outcomes such as quality of life and functional status; and to provide recommendations for primary care physicians and specialists for the diagnosis, evaluation, and management of anemia in patients with CHF...

Anthracycline-induced cardiotoxicity (ACT) is a severe complication in children and young adults that may lead to congestive heart failure. Some risk factors have been identified: high anthracycline cumulative dose, high radiation dose delivered on the cardiac area, or young age during the treatment. Primary prevention is not clearly defined in children. The dexrazoxane iron chelator seems to be interesting based on its short-term cardioprotective property in patients receiving doxorubicin-containing regimens...

BACKGROUND: While transfusion and iron chelation therapy for thalassemia major (TM) has improved dramatically in recent years, the consequences of this improvement (current rates of survival and TM-related complications) remain unknown. METHODS: This nationwide population-based cohort study analyzed 2007-2011 data obtained from the Taiwanese National Health Insurance Research Database. RESULTS: After excluding those patients receiving hematopoietic stem cell transplantation, we enrolled 454 patients with TM who received transfusion and chelation therapy (median age, 17...

PURPOSE OF REVIEW: Loss of skeletal muscle oxidative capacity is a common feature of chronic diseases such as chronic obstructive pulmonary disease, type 2 diabetes, and congestive heart failure. It may lead to physical impairments and has been suggested to contribute to metabolic inflexibility-induced cardiometabolic risk. The mechanism underlying loss of muscle oxidative capacity is incompletely understood. This review discusses the role of mitophagy as a driving force behind the loss of skeletal muscle oxidative capacity in these patients...

INTRODUCTION: Iron deficiency in congestive heart failure (CHF), with or without concomitant anaemia, is associated with health-related quality of life, NYHA functional class, and exercise capacity. Prospective, randomised studies have demonstrated that correcting iron deficiency improves the quality of life and functional status of patients with CHF, including those who do not have anaemia. OBJECTIVE: The aim of this study was to analyse how frequently these iron parameters are tested and thus determine the extent to which this quality improvement tool has been implemented in patients admitted with CHF...

PHD3 belongs to the family of 2-oxoglutarate and iron-dependent dioxygenases and is a critical regulator of HIF-1α. Its expression is increased in cardiovascular diseases such as cardiomyopathy, myocardial ischemia-reperfusion injury, and congestive heart failure. However, the association between PHD3 and atherosclerosis has not been clearly elucidated. In the present study, we investigated the potential effect and mechanism of PHD3 in apolipoprotein E-deficient (ApoE-/-) mice. Murine PHD3 lentivirus and shRNA -PHD3 lentivirus were constructed and injected intravenously into ApoE-/- mice fed on a high fat diet...

Chronic kidney disease (CKD), cardiac damage (CD) and the combination of the two are associated with increased morbidity and death in patients admitted to vascular surgery units. We assessed the prevalence of cardiac and renal damage and cardiorenal syndrome (CRS) in 563 patients with abdominal aortic aneurysms (AAA) who underwent cardiac screening before either an endovascular procedure (EVAR) or open surgery (OS) for aneurysm repair. CD was defined by ≥stage B as per the ACC/AHA classification of congestive heart failure (CHF), while CKD was defined by estimated GFR <60 mL/min/1...

Cardiotoxicity is a serious complication of anticancer therapy by anthracycline antibiotics. Except for intercalation into DNA/RNA structure, inhibition of DNA-topoisomerase and histone eviction from chromatin, the main mechanism of their action is iron-mediated formation of various forms of free radicals, which leads to irreversible damage to cancer cells. The most serious adverse effect of anthracyclines is, thus, cardiomyopathy leading to congestive heart failure, which is caused by the same mechanisms. Here, we briefly summarize the basic types of free radicals formed by anthracyclines and the main processes how to scavenge them...

Renal anemia is caused by the deficiency of endogenous erythropoietin (Epo) due to renal dysfunction. We think that it is possible to slow the progression of chronic kidney disease (CKD) in case we initiate Epo early in pre-dialysis patients, especially in the non-diabetic population. Erythropoiesis stimulating agent (ESA) treatments targeting mild anemia (10-12 g/dl) can decrease the risk of occurrence of cardiovascular disease (CVD) in patients with hypertension, diabetes mellitus and congestive heart failure...

Iron deficiency and anaemia occur frequently in patients with chronic kidney disease (CKD) or chronic heart failure (CHF) and are associated with lower quality of life and higher mortality. Treating anaemia with erythropoietic growth factors produces no improvement. In recent years, the focus has therefore shifted to correction of iron deficiency. Chronic inflammation in CKD increases the production of hepcidin, which blocks iron absorption from the intestine and leads to less efficient re-use of iron from the macrophages...

OBJECTIVES: Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality. Iron deficiency, with or without anaemia, is associated with other chronic conditions, such as congestive heart failure, where it predicts a worse outcome. However, the prevalence of iron deficiency in COPD is unknown. This observational study aimed to determine the prevalence of iron deficiency in COPD and associations with differences in clinical phenotype. SETTING: University hospital outpatient clinic...

OBJECTIVE: In chronic kidney disease (CKD), both anemia and deregulated phosphate metabolism are common and predictive of adverse outcome. Previous studies suggest that iron status influences phosphate metabolism by modulating proteolytic cleavage of FGF23 into C-terminal fragments. Red cell distribution width (RDW) was recently identified as a strong prognostic determinant for cardiovascular morbidity and mortality, independently of iron status. We assessed whether RDW is associated with FGF23 cleaving in CKD patients with heart failure...
