Diagnosis and Treatment of Iron Deficiency in Heart Failure: OFICSel study by the French Heart Failure Working Group.

AIMS: Iron deficiency (ID) occurs in about 50% of patients with heart failure (HF). The European Society of Cardiology (ESC) recommends ID diagnostic testing in newly diagnosed patients with HF and during follow-up, with intravenous iron supplementation (IS) only recommended in patients with HF with reduced ejection fraction (HFrEF). This study aimed to assess prevalence, clinical characteristics, and application of ESC guidelines for ID and IS in patients with HF in the real-life clinical setting. METHODS AND RESULTS: The French transversal multicentre OFICSel registry (300 cardiologists) conducted in 2017 included patients hospitalized for HF at least once in the previous 5 years. Diverse adult patients were eligible including inpatients and outpatients and those with acute and chronic HF. Data were collected from cardiologists and patients using study-specific surveys. Data included demographic and clinical data, as well as HF and ID management data. Overall, 2822 patients, mainly male (69.3%) with a median age of 69 years (interquartile range 58-78), were included. A total of 1075 patients (38.1%) were tested for ID, with 364 (33.9%) diagnosed. Of these, 168 (46.2%) received IS: 128 (76.2%) intravenous IS and 40 (23.8%) oral. Among the 201 patients with HFrEF diagnosed with ID, 99 (49.3%) received IS: 79 (79.8%) intravenous IS and 20 (20.2%) oral. CONCLUSIONS: In clinical practice, only one-third of patients with HF had a diagnostic test for ID. In patients with ID with HFrEF, only 39.3% received intravenous IS as recommended. Thus, in general, cardiologists should be encouraged to follow the ESC guidelines to ensure optimal treatment for patients with HF.

Management of valvulopathies with acute severe heart failure and cardiogenic shock.

Cardiogenic shock is a critical clinical situation, requiring rapid diagnosis, aetiological assessment and immediate initiation of therapy. In industrialized countries, aortic stenosis is the most frequent left-sided valvulopathy, followed by mitral regurgitation, aortic regurgitation and mitral stenosis. Severe valvulopathies leading to cardiogenic shock are not rare conditions, but few data are available on their optimal management. Therapeutic options for such critical conditions include inotropic agents, mechanical support (when feasible) and rapid valvular intervention. Although surgery remains the gold-standard treatment for severe valvular disease, mortality is frequently prohibitive in the setting of cardiogenic shock, necessitating consideration of alternative therapies. Percutaneous management of valvulopathies has emerged as an alternative treatment for patients deemed at high surgical risk in a stable condition. Although few published data are available, catheter-based interventions may be feasible in the cardiogenic shock setting. This review offers an overview of different valvulopathies in the cardiogenic shock setting, and summarizes the different therapeutic options currently available in such critical situations.

Extracorporeal membrane oxygenation support in acute circulatory failure: A plea for regulation and better organization.

Emergent implantation of temporary mechanical circulatory support using venoarterial ECMO (ECLS for extracorporeal Life Support) is increasingly adopted in various indications of acute circulatory failure refractory to optimal medical treatment. To implant such devices, but also to provide appropriate daily management, expertise and adapted technical platform are required. Organization, coordination and regulation of such program are not clearly established in our country. We propose a dedicated territorial organization to improve and facilitate management of these specific and most severe patients.

Is hypertriglyceridemia atherogenic?

PURPOSE OF REVIEW: Hypertriglyceridemia occurs mainly because of metabolic disorders secondary to diabetes, alcohol intake, and/or overweight. Genetic factors have also been clearly identified in most severe cases. Triglycerides are generally considered as 'bystanders' for cardiovascular diseases. However, biological and basic research provides strong data suggesting that triglyceride-rich lipoproteins could be involved in the pathophysiology of cardiovascular diseases. RECENT FINDINGS: The REDUCE-IT trial recently showed that icosapent ethyl reduces major cardiovascular events and related death. SUMMARY: For many years, low-density lipoproteins (LDLs) have been considered the Holy Grail for atherosclerotic cardiovascular disease management. New data from basic research in biology, epidemiology, genetics, and preliminary clinical trials support the hypothesis that triglyceride-rich lipoproteins could be the causal factors for atherosclerotic cardiovascular disease; hence, triglyceride should be taken into consideration in the management of these patients. Omega-3-fatty acids used in the REDUCE-IT trial reduced the residual cardiovascular risk efficiently beyond statins. However, its effect has to be completely understood as it seems to be unrelated to LDLc or triglyceride reduction, but linked to pleiotropic effects involving inflammation, platelet adhesion, and plaque instability reduction, paving the way for trials that will target more specific potential pathophysiologic pathways.

Impact of sacubitril-valsartan combination in patients with chronic heart failure and sleep apnoea syndrome: the ENTRESTO-SAS study design.

AIMS: Sleep-disordered breathing (SDB) is a highly prevalent co-morbidity in patients with chronic heart failure (CHF) and can play a detrimental role in the pathophysiology course of CHF. However, the best way to manage SDB in CHF remains a matter of debate. Sacubitril-valsartan has been included in the 2016 European Society of Cardiology guidelines as an alternative to angiotensin-converting enzyme inhibitors to further reduce the risk of progression of CHF, CHF hospitalization, and death in ambulatory patients. Sacubitril and valsartan are good candidates for correcting SDB of CHF patients because their known mechanisms of action are likely to counteract the pathophysiology of SDB in CHF. METHODS AND RESULTS: The ENTRESTO-SAS trial is a 3-month, multicentric, prospective, open-label real-life cohort study. Patients eligible for sacubitril-valsartan treatment (i.e. adults with left ventricular ejection fraction ≤35%, who remain symptomatic despite optimal treatment with an angiotensin-converting enzyme inhibitor, a beta-blocker, and a mineralocorticoid receptor antagonist) will be evaluated before and after 3 months of treatment (nocturnal ventilatory polygraphy, echocardiography, laboratory testing, and quality-of-life and SDB questionnaires). The primary outcome is the change in the Apnoea-Hypopnoea Index, before and after 3 months of treatment. One hundred twenty patients are required to detect a significant 20% improvement of the Apnoea-Hypopnoea Index with a power of 90% at an alpha risk of 5%. CONCLUSIONS: In the context of the SERVE-HF study, physicians are waiting for new trials and alternative therapies. We sought to assess in the ENTRESTO-SAS trial whether sacubitril-valsartan could improve the outcome of SDB in CHF patients.

The interleukin-1ß modulator gevokizumab reduces neointimal proliferation and improves reendothelialization in a rat carotid denudation model.

OBJECTIVE: Excessive neointima formation often occurs after arterial injury. Interleukin-1ß (IL-1ß) is a potent pleiotropic cytokine that has been shown to regulate neointimal proliferation. We investigated the effects of the IL-1ß modulator gevokizumab in a rat carotid denudation model. METHODS: Sprague-Dawley rats were subjected to balloon denudation of the right carotid artery and were then randomized to receive a single subcutaneous infusion immediately after balloon injury of saline (control group, n = 13) or gevokizumab (gevokizumab groups, n = 15 in each group: 1, 10 and 50 mg/kg). We evaluated the treatment effects on carotid intima-media thickness (IMT) using ultrasonography, on endothelial regrowth using Evans Blue staining and on inflammatory response using histology. We also assessed the effects of IL-1ß and gevokizumab on human umbilical vein endothelial cells (HUVEC) and rat smooth muscle cells. RESULTS: We found that carotid IMT, in the proximal part of the denuded artery at day 28, was decreased by gevokizumab 1 mg/kg compared with controls. Neointima area and the intima/media area ratio were both reduced in the gevokizumab 1 mg/kg-treated group. Gevokizumab at the 1 mg/kg dose also improved endothelial regrowth. No effect was observed with gevokizumab 10 or 50 mg/kg. Gevokizumab also decreased the inflammatory effect of IL-1ß in in vitro cell experiments and protected HUVECs from IL-1ß's deleterious effects on cell migration, apoptosis and proliferation. CONCLUSION: A single administration of gevokizumab 1 mg/kg improves endothelial regrowth and reduces neointima formation in rats following carotid denudation, at least in part through its beneficial effects on endothelial cells.

Systems medicine approaches for the definition of complex phenotypes in chronic diseases and ageing. From concept to implementation and policies.

Chronic diseases are diseases of long duration and slow progression. Major NCDs (cardiovascular diseases, cancer, chronic respiratory diseases, diabetes, rheumatologic diseases and mental health) represent the predominant health problem of the Century. The prevention and control of NCDs are the priority of the World Health Organization 2008 Action Plan, the United Nations 2010 Resolution and the European Union 2010 Council. The novel trend for the management of NCDs is evolving towards integrative, holistic approaches. NCDs are intertwined with ageing. The European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) has prioritised NCDs. To tackle them in their totality in order to reduce their burden and societal impact, it is proposed that NCDs should be considered as a single expression of disease with different risk factors and entities. An innovative integrated health system built around systems medicine and strategic partnerships is proposed to combat NCDs. It includes (i) understanding the social, economic, environmental, genetic determinants, as well as the molecular and cellular mechanisms underlying NCDs; (ii) primary care and practice-based interprofessional collaboration; (iii) carefully phenotyped patients; (iv) development of unbiased and accurate biomarkers for comorbidities, severity and follow up of patients; (v) socio-economic science; (vi) development of guidelines; (vii) training; and (viii) policy decisions. The results could be applicable to all countries and adapted to local needs, economy and health systems. This paper reviews the complexity of NCDs intertwined with ageing. It gives an overview of the problem and proposes two practical examples of systems medicine (MeDALL) applied to allergy and to NCD co-morbidities (MACVIA-LR, Reference Site of the European Innovation Partnership on Active and Healthy Ageing).
