Practical Guidance for Diagnosing and Treating Iron Deficiency in Patients with Heart Failure:Why, Who and How?
Iron deficiency (ID) is a comorbid condition frequently seen in patients with heart failure (HF). Iron has an important role in the transport of oxygen, and is also essential for skeletal and cardiac muscle, which depend on iron for oxygen storage and cellular energy production. Thus, ID per se, even without anaemia, can be harmful. In patients with HF, ID is associated with a poorer quality of life (QoL) and exercise capacity, and a higher risk of hospitalisations and mortality, even in the absence of anaemia. Despite its negative clinical consequences, ID remains under-recognised. However, it is easily diagnosed and managed, and the recently revised 2021 European Society of Cardiology (ESC) guidelines on HF provide specific recommendations for its diagnosis and treatment. Prospective randomised controlled trials in patients with symptomatic HF with reduced ejection fraction (HFrEF) show that correction of ID using intravenous iron (principally ferric carboxymaltose [FCM]) provides improvements in symptoms of HF, exercise capacity and QoL, and a recent trial demonstrated that FCM therapy following hospitalisation due to acute decompensated HF reduced the risk of subsequent HF hospitalisations. This review provides a summary of the epidemiology and pathophysiology of ID in HFrEF, and practical guidance on screening, diagnosing, and treating ID
Screening, diagnosis and treatment of iron deficiency in chronic heart failure:putting the 2016 European Society of Cardiology heart failure guidelines into clinical practice
Iron deficiency is common in patients with chronic heart failure (CHF) and is associated with reduced exercise performance, impaired health-related quality of life and an increased risk of mortality, irrespective of whether or not anaemia is present. Iron deficiency is a serious but treatable condition. Several randomized controlled clinical trials have demonstrated the ability of intravenous (IV) iron, primarily IV ferric carboxymaltose (FCM), to correct iron deficiency in patients with heart failure with reduced ejection fraction (HFrEF), resulting in improvements in exercise performance, CHF symptoms and health-related quality of life. The importance of addressing the issue of iron deficiency in patients with CHF is reflected in the 2016 European Society of Cardiology (ESC) heart failure guidelines, which recognize iron deficiency as an important co-morbidity, independent of anaemia. These guidelines recommend that all newly diagnosed heart failure patients are routinely tested for iron deficiency and that IV FCM should be considered as a treatment option in symptomatic patients with HFrEF and iron deficiency (serum ferritin</p

Epidemiology and resource use in Spanish type 2 diabetes patients without previous cardiorenal disease: CaReMe Spain study summary.
To determine the first manifestation of cardiovascular or kidney disease (CVKD) and associated resource use in type 2 diabetes mellitus (T2DM) patients during seven years of follow-up. Observational-retrospective secondary data study using medical records of patients aged â„18 years with T2DM and without prior CVKD between 2013 and 2019. The index date was 01/01/2013 (fixed date). The manifestation of CVKD was defined by the first diagnosis of heart-failure (HF), chronic-kidney disease (CKD), myocardial-infarction (MI), stroke or peripheral-artery disease (PAD). The main variables were baseline characteristics, manifestation of CVKD, mortality, resource use and costs. Descriptive analyses and Cox model were applied to the data. 26,542 patients were selected (mean age: 66.6 years, women: 47.8%, mean duration of T2DM: 17.1 years). 18.7% (N=4974) developed a first CVKD manifestation during the seven years [distribution: HF (22.4%), CKD (36.6%), MI (14.5%), stroke (15.3%) and PAD (11.3%)]. Overall mortality was 8.3% (N=2214). The mortality risk of the group that developed HF or CKD as the first manifestation compared to the CVKD-free cohort was higher [HR: 2.5 (95% CI: 1.8-3.4) and 1.8 (95% CI: 1.4-2.3)], respectively. The cumulative costs per patient of HF (âŹ50,942.80) and CKD (âŹ48,979.20) were higher than MI (âŹ47,343.20) and stroke (âŹ47,070.30) and similar to PAD (âŹ51,240.00) vs. âŹ13,098.90 in patients who did not develop CVKD, p In T2DM patients, HF and CKD were the first most common manifestations and had higher mortality and re-hospitalisation rates. HF and CKD were associated with the highest resource use and costs for the Spanish National-Health-System
Genetic Etiology for Alcohol-Induced Cardiac Toxicity
Alcoholic cardiomyopathy (ACM) is defined by a dilated and impaired left ventricle due to chronic excess alcohol consumption. It is largely unknown which factors determine cardiac toxicity on exposure to alcohol. This study sought to evaluate the role of variation in cardiomyopathy-associated genes in the pathophysiology of ACM, and to examine the effects of alcohol intake and genotype on dilated cardiomyopathy (DCM) severity. The authors characterized 141 ACM cases, 716 DCM cases, and 445 healthy volunteers. The authors compared the prevalence of rare, protein-altering variants in 9 genes associated with inherited DCM. They evaluated the effect of genotype and alcohol consumption on phenotype in DCM. Variants in well-characterized DCM-causing genes were more prevalent in patients with ACM than control subjects (13.5% vs. 2.9%; p = 1.2 Ă10 â»â”), but similar between patients with ACM and DCM (19.4%; p = 0.12) and with a predominant burden of titin truncating variants (TTNtv) (9.9%). Separately, we identified an interaction between TTN genotype and excess alcohol consumption in a cohort of DCM patients not meeting ACM criteria. On multivariate analysis, DCM patients with a TTNtv who consumed excess alcohol had an 8.7% absolute reduction in ejection fraction (95% confidence interval: â2.3% to â15.1%; p < 0.007) compared with those without TTNtv and excess alcohol consumption. The presence of TTNtv did not predict phenotype, outcome, or functional recovery on treatment in ACM patients. TTNtv represent a prevalent genetic predisposition for ACM, and are also associated with a worse left ventricular ejection fraction in DCM patients who consume alcohol above recommended levels. Familial evaluation and genetic testing should be considered in patients presenting with ACM
Preoperative INTERMACS Profiles Determine Postoperative Outcomes in Critically Ill Patients Undergoing Emergency Heart Transplantation
Repetitive use of levosimendan in advanced heart failure : need for stronger evidence in a field in dire need of a useful therapy
Patients in the latest stages of heart failure are severely compromised, with poor quality of life and frequent hospitalizations. Heart transplantation and left ventricular assist device implantation are viable options only for a minority, and intermittent or continuous infusions of positive inotropes may be needed as a bridge therapy or as a symptomatic approach. In these settings, levosimendan has potential advantages over conventional inotropes (catecholamines and phosphodiesterase inhibitors), such as sustained effects after initial infusion, synergy with beta-blockers, and no increase in oxygen consumption. Levosimendan has been suggested as a treatment that reduces re-hospitalization and improves quality of life. However, previous clinical studies of intermittent infusions of levosimendan were not powered to show statistical significance on key outcome parameters. A panel of 45 expert clinicians from 12 European countries met in Rome on November 24-25, 2016 to review the literature and envision an appropriately designed clinical trial addressing these needs. In the earlier FIGHT trial (daily subcutaneous injection of liraglutide in heart failure patients with reduced ejection fraction) a composite Global Rank Score was used as primary end-point where death, re-hospitalization, and change in N-terminalprohormone-brain natriuretic peptide level were considered in a hierarchical order. In the present study, we tested the same end-point post hoc in the PERSIST and LEVOREP trials on oral and repeated i.v. levosimendan, respectively, and demonstrated superiority of levosimendan treatment vs placebo. The use of the same composite end-point in a properly powered study on repetitive levosimendan in advanced heart failure is strongly advocated
