Iron deficiency (ID) is an emerging problem in patients with chronic heart failure (HF) and can be a potential therapeutic target. However, not much is known about the prevalence, predictors, and prognosis of ID in patients with chronic HF. In an international pooled cohort comprising 1,506 patients with chronic HF, we studied the clinical associates of ID and its prognostic consequences. Iron deficiency (defined as a ferritin level <100 μg/L or ferritin 100-299 μg/L with a transferrin saturation <20%) was present in 753 patients (50%). Anemic patients were more often iron deficient than nonanemic patients (61.2% vs 45.6%, P < .001). Other independent predictors of ID were higher New York Heart Association class, higher N-terminal pro-brain-type natriuretic peptide levels, lower mean corpuscular volume levels, and female sex (all P < .05). During follow-up (median 1.92 years, interquartile range 1.18-3.26 years), 440 patients died (29.2%). Kaplan-Meier survival analysis revealed ID as a strong predictor for mortality (log rank χ2 10.2, P = .001). In multivariable hazard models, ID (but not anemia) remained a strong and independent predictor of mortality (hazard ratio 1.42, 95% confidence interval 1.14-1.77, P = .002). Finally, the presence of ID significantly enhanced risk classification and integrated discrimination improvement when added to a prediction model with established risk factors. Iron deficiency is common in patients with chronic HF, relates to disease severity, and is a strong and independent predictor of outcome. In this study, ID appears to have greater predictive power than anemia.

Iron deficiency (ID) is a common co‐morbidity in patients with heart failure (HF). The present meta‐analysis evaluates the effect of intravenous (IV) iron‐carbohydrate complex supplementation in patients with HF with reduced ejection fraction (HFrEF) and ID/iron deficiency anaemia (IDA). Randomized controlled trials (RCTs) comparing IV iron‐carbohydrate complexes with placebo/standard of care in patients with HFrEF with ID/IDA were identified using Embase (from 1957) and PubMed (from 1989) databases through 25 May 2021. Twelve RCTs including 2381 patients were included in this analysis. The majority (90.8%) of patients receiving IV iron‐carbohydrate therapy were administered ferric carboxymaltose (FCM); 7.5% received iron sucrose and 1.6% received iron isomaltoside. IV iron‐carbohydrate therapy significantly reduced hospitalization for worsening HF [0.53 (0.42–0.65); P < 0.0001] and first hospitalization for worsening HF or death [0.75 (0.59–0.95); P = 0.016], but did not significantly impact all‐cause mortality, compared with control. IV iron‐carbohydrate therapy significantly improved functional and exercise capacity compared with the control. There was no significant difference in outcome between IV iron‐carbohydrate formulations when similar endpoints were measured. No significant difference in adverse events (AE) was observed between the treatment groups. IV iron‐carbohydrate therapy resulted in improvements in a range of clinical outcomes and increased functional and exercise capacity, whereas AEs were not significantly different between IV iron‐carbohydrate and placebo/standard of care arms. These findings align with the European Society of Cardiology's 2021 HF guidelines, which recommend the consideration of FCM in symptomatic patients with a left ventricular ejection fraction < 45% and ID.

In patients with chronic heart failure, iron deficiency, even in the absence of anaemia, can aggravate the underlying disease and have a negative impact on clinical outcomes and quality of life. The 2016 European Society of Cardiology guidelines for the diagnosis and treatment of acute and chronic heart failure recognize iron deficiency as a co‐morbidity in chronic heart failure and recommend iron status screening in all newly diagnosed patients with chronic heart failure. Furthermore, the guidelines specifically recommend considerations of intravenous iron therapy, ferric carboxymaltose, for the treatment of iron deficiency. However, in spite of these recommendations, iron deficiency remains often overlooked and undertreated. This may be due, in part, to the lack of clinical context and practical guidance accompanying the guidelines for the treating physician. Here, we provide practical guidance complemented by a case study to assist and improve the timely diagnosis, treatment, and routine management of iron deficiency in patients with chronic heart failure.

Heart failure (HF), particularly of an ischemic etiology, is steadily increasing worldwide. Non-anemic iron deficiency (ID) is highly prevalent among HF patients, and it has been related to worse outcomes. Growth differentiation factor 15 (GDF15) has been related to atherosclerotic cardiovascular (CV) disease, HF and iron pathophysiology. Nevertheless, the specific potential role of GDF15 in HF patients with ID has not been fully explored. In this cross-sectional study we determined serum GDF15 levels in 60 HF patients with ID from the IRON-PATH II study. The discriminative capacity of GDF15 in logistic regression models for classifying these patients according to ischemic etiology was defined as the primary endpoint. Additionally, relationships between GDF15 levels and impaired right ventricle function, impaired functional capacity and HF were included as secondary endpoints. GDF15 was inversely related to tricuspid annular plane systolic excursion (TAPSE) and the six-minute walking test (6MWT), and positively related to hallmarks of HF [i.e., N-terminal prohormone of brain natriuretic peptide (NT-proBNP)] and other molecules influenced by HF progression [i.e., creatinine and ferritin]. Moreover, GDF15 was inversely related to hemoglobin, suggesting a potential link to iron homeostasis. Furthermore, GDF15 showed good classification capacity and improved the accuracy of a logistic regression model for ischemic HF classification in patients with ID. Overall, the findings of this study propose serum GDF15 levels as a potential tool for the classification of HF patients with ID according to the ischemic etiology.

Background: In arrhythmogenic right ventricular cardiomyopathy (ARVC) non-invasive scar evaluation is not included among the diagnostic criteria or the predictors of ventricular arrhythmias (VA) and sudden death (SD). Computed tomography (CT) has excellent spatial resolution and allows a clear distinction between myocardium and fat; thus, it has great potential for the evaluation of myocardial scar in ARVC. Objective: The objective of this study is to evaluate the feasibility, and the diagnostic and prognostic value of semi-automated quantification of right ventricular (RV) fat replacement from CT images. Methods: An observational case–control study was carried out including 23 patients with a definite (19) or borderline (4) ARVC diagnosis and 23 age- and sex-matched controls without structural heart disease. All patients underwent contrast-enhanced cardiac CT. RV images were semi-automatically reconstructed with the ADAS-3D software (ADAS3D Medical, Barcelona, Spain). A fibrofatty scar was defined as values of Hounsfield Units (HU) <−10. Within the scar, a border zone (between −10 HU and −50 HU) and dense scar (<−50 HU) were distinguished. Results: All ARVC patients had an RV scar and all scar-related measurements were significantly higher in ARVC cases than in controls (p < 0.001). The total scar area and dense scar area showed no overlapping values between cases and controls, achieving perfect diagnostic performance (sensitivity and specificity of 100%). Among ARVC patients, 16 (70%) had experienced sustained VA or aborted SD. Among all clinical, ECG and imaging parameters, the dense scar area was the only one with a statistically significant association with VA and SD (p = 0.003). Conclusions: In ARVC, RV myocardial fat quantification from CT is feasible and may have considerable diagnostic and prognostic value.

A reduced estimated glomerular filtration rate (eGFR) has been described as a predictor of heart failure (HF). However, the increased risk across eGFR categories has not been fully evaluated, which is especially relevant in older individuals in whom both the prevalence of HF and decreased eGFR are higher. Furthermore, this association has not been studied in Mediterranean populations, where coronary heart disease (CHD), a frequent cause of HF, has a low prevalence. We performed a retrospective cohort study using the electronic medical records from primary and hospital settings in northeastern Spain. We included 125,053 individuals ≥60 years old with the determination of creatinine and without diagnosis or previous admission due to HF. The eGFR was calculated according to the CKD-EPI formula and classified by clinical categories. The association between eGFR, as a continuous and categorical variable, and the risk of admission due to HF was assessed by Cox proportional risk analysis, considering death as a competitive risk. During a median follow-up of 38.8 months, 2,176 individuals (1.74%) were hospitalized due to HF. The unadjusted admission rates were 4.02, 13.0, 26.0, and 48.6 per 1000 person-years for eGFR > 60, 45-59, 30-44, and 15-29 ml/min/1.73 m , respectively. The corresponding hazard ratios (95% confidence interval; reference eGFR 60-89) were 1.38 (95% CI 1.23-1.55), 2.02 (95% CI 1.76-2.32) and 3.46 (95% CI 2.78-4.31). In this Mediterranean community-based cohort of individuals ≥60 years old without previous HF, the risk of admission due to HF gradually increased with decreasing eGFR.

Aims CORE is a continuing medical education initiative designed to support the evidence‐based management of heart failure (HF) in the primary and secondary care settings. The goal of the CORE Needs Assessment Survey is to describe current clinical practice patterns and attitudes among global stakeholders in HF care. Methods and results The CORE Steering Committee guided the development of survey questions to assess clinical practice, confidence, and attitudes/perceptions among cardiologists, primary care physicians, and nurses involved in HF management. In total, 346 healthcare professionals from Australia (n = 59), Austria (n = 59), Canada (n = 60), Spain (n = 58), Sweden (n = 52), and the UK (n = 58) contributed survey data. Results revealed multiple gaps over the spectrum of HF care, including diagnosis (low recognition of the signs and symptoms of HF and limited use of diagnostic tests), treatment planning (underuse of recommended agents and subtherapeutic dosing), treatment monitoring and adjustment (lack of adherence to recommendations), and long‐term management (low confidence in providing patient education). Although primary care and specialist physicians and nurses shared common unmet needs, healthcare professional‐specific clinical gaps were also identified. Conclusions The CORE Needs Assessment Survey provides timely data describing current clinical practices and attitudes among physicians and nurses regarding key aspects of HF care. These findings will be useful for guiding the development of interventions tailored to the specific educational needs of different provider types and designed to support the evidence‐based care of patients with HF.

In patients with heart failure and iron deficiency, intravenous iron therapy improved functional capacity and the quality of life. The benefit was similar in patients with anemia and those without anemia. Iron therapy may have a role in treating heart failure when iron deficiency is also present. In patients with heart failure and iron deficiency, intravenous iron therapy improved functional capacity and the quality of life. Iron therapy may have a role in treating heart failure when iron deficiency is also present. Recent developments in the management of chronic heart failure in patients with an impaired left ventricular ejection fraction have changed the natural history of this clinical syndrome and improved patients' outcomes. 1 , 2 However, the normal daily activities of many patients with heart failure remain restricted; they report symptoms of fatigue and dyspnea that adversely affect their quality of life, leading to high morbidity. 3 , 4 Therapeutic options to improve functional capacity in patients with heart failure are limited, and novel therapies are needed. Numerous mechanisms unrelated to hemodynamic dysfunction may underlie impaired exercise tolerance in patients with chronic heart failure. Among . . .

Heart failure (HF) is frequent and its prevalence is increasing. We aimed to evaluate the epidemiologic features of HF patients, the 1-year follow-up outcomes and the independent predictors of those outcomes at a population level. Population-based longitudinal study including all prevalent HF cases in Catalonia (Spain) on December 31st, 2012. Patients were divided in 3 groups: patients without a previous HF hospitalization, patients with a remote (>1 year) HF hospitalization and patients with a recent (<1 year) HF admission. We analyzed 1year all-cause and HF hospitalizations, and all-cause mortality. Logistic regression was used to identify the independent predictors of each of those outcomes. A total of 88,195 patients were included. Mean age was 77 years, 55% were women. Comorbidities were frequent. Fourteen percent of patients had never been hospitalized, 71% had a remote HF hospitalization and 15% a recent hospitalization. At 1-year follow-up, all-cause and HF hospitalization were 53% and 8.8%, respectively. One-year all-cause mortality rate was 14%, and was higher in patients with a recent HF hospitalization (24%). The presence of diabetes mellitus, atrial fibrillation or chronic kidney disease was independently associated with all-cause and HF hospitalization and all-cause mortality. Hospital admissions and emergency department visits the previous year were also found to be independently associated with the three study outcomes. Outcomes are different depending on the HF population studied. Some comorbidity, an all-cause hospitalization or emergency department visit the previous year were associated with a worse outcome.

Background Iron deficiency (ID) is a common co‐morbidity associated with chronic heart failure (CHF), which has unfavourable clinical and prognostic consequences. In Ferinject Assessment in Patients with IRon Deficiency and Chronic Heart Failure (FAIR‐HF), the treatment with i.v. ferric carboxymaltose (FCM) improved symptoms and quality of life over a 24 week period. Ferric CarboxymaltOse evaluatioN on perFormance in patients with IRon deficiency in coMbination with chronic Heart Failure (CONFIRM‐HF) was designed to test a simplifieddosage scheme of FCM during a longer follow‐up period. Methods CONFIRM‐HF, a double‐blind, multi‐centre, prospective, randomized, two‐arm study, enrolled ambulatory patients with symptomatic CHF [New York Heart Association (NYHA) class II/III] with left ventricular ejection fraction ≤45%, BNP >100 pg/mL, or NT‐proBNP >400 pg/mL, presence of ID [defined as ferritin <100 ng/mL, or ferritin 100–300 ng/mL if transferrin saturation (TSAT) <20%], and haemoglobin (Hb) <15 g/dL. Patients were randomized 1:1 to treatment with FCM or placebo for 52 weeks. Primary endpoint is change in 6‐minute walk test (6MWT) distance from baseline to Week 24. Secondary endpoints are: change in 6MWT from baseline to Weeks 6, 12, 36, and 52; Patient Global Assessment score at Weeks 6, 12, 24, 36, and 52; and change from baseline to Weeks 6, 12, 24, 36, and 52 in NYHA class, fatigue score, and quality of life. Safety endpoints include overall safety over the treatment period of 52 weeks. Study medication was administered in single doses as undiluted bolus injection of up to 1000 mg of iron or normal saline at Day 0 and Week 6 up to iron repletion. Further doses of study medication could be administered at Weeks 12, 24, and 36 if a patient still had ID. Results Overall, 304 patients were recruited in 41 centres in nine countries. Conclusion This study will provide further information on the efficacy and safety of iron therapy with i.v. FCM in CHF patients with ID over a 1 year period using a simplified dosing scheme.
