RESUMO
Heart failure remains, despite increasing therapeutic advances, a major burden in terms of public health. It is associated with a significant mortality and dramatically impacts the daily life of these patients with, among other things, repeated and prolonged hospitalizations. This article aims to focus on the therapeutic modalities for the management of patients with heart failure and reduced ejection fraction (HFrEF) recommended by the European Society of Cardiology. A significant change is taking place in pharmacological treatment following the discovery of new drug classes.
L'insuffisance cardiaque (IC) demeure, malgré des avancées thérapeutiques croissantes, un fardeau majeur en termes de santé publique (1). Elle est grevée d'une importante mortalité et impacte de manière significative le quotidien de ces patients avec, entre autres, des hospitalisations répétées et prolongées (hIC). Cet article vise à mettre l'accent sur les modalités thérapeutiques de prise en charge du patient présentant une IC à fraction d'éjection réduite (HFrEF) recommandées par la Société Européenne de Cardiologie. Un changement important s'opère au niveau du traitement pharmacologique suite à la découverte de nouvelles classes médicamenteuses.

While euthanasia has been legalized in a growing number of countries, organ donation after euthanasia is only performed in Belgium, the Netherlands, Spain, and Canada. Moreover, the clinical practice of heart donation after euthanasia has never been reported before. We describe the first case of a heart donated after euthanasia, reconditioned with thoraco-abdominal normothermic regional perfusion, preserved using cold storage while being transported to a neighboring transplant center, and then successfully transplanted following a procurement warm ischemic time of 17 min. Heart donation after euthanasia using thoraco-abdominal normothermic regional perfusion is feasible, it could expand the heart donor pool and reduce waiting lists in countries where organ donation after euthanasia can be performed.

Heart donation after circulatory death (DCD) can significantly expand the heart donor pool, helping to overcome the problem of organ shortage and the increase in waiting list mortality and morbidity. To improve the outcome of DCD heart transplantation, thoraco-abdominal normothermic regional perfusion (TA-NRP) can be performed by selectively restoring circulation followed by in vivo functional heart assessment. Here, we report on the use of periprocedural transoesophageal echocardiography (TOE) as a minimally invasive cardiac assessment tool during different stages of a DCD heart procurement procedure using TA-NRP. We conclude that TOE is a valuable method to assess the donor heart for transplantation eligibility before and after withdrawal of life-sustaining therapy and during subsequent TA-NRP.

BACKGROUND: The improvement in survival rates for heart transplant recipients (HTRs) has increased their risk of developing extracardiac diseases such as abdominal aortic aneurysms (AAAs). The purposes of this study were to evaluate the prevalence and to describe the clinical features and natural history of AAA in HTRs. METHODS: A retrospective review of all patients (375) who underwent heart transplantation (HT) at our center over a 32-year period (1983-2015) was carried out. RESULTS: We identified 20 patients (5.3%) with AAA. All but one patient were male (95%), and most of them (80%) had a history of ischemic heart disease (IHD) prior to transplantation. The mean age of the patients with AAA at transplant was 57.2 ± 7.3 years (range: 42-62 years). Seven of the 20 patients with AAA already had an AAA (30-55 mm) prior to transplantation. The average aneurysm size at the time of diagnosis was 40.9 ± 9.6 mm, and the average patient age at the time of diagnosis was 62.2 ± 8.3 years. The mean linear expansion rate was 10.6 ± 2.12 mm/y, and the exponential expansion rate was 0.220 ± 0.040 year-1, respectively. The median follow-up time was 5.4 years (range 0.1-27.4 years). The median survival was 143 months (95% confidence interval (CI) 65 to 180 months) for the 20 HTRs with AAA and 68.8 months (95% CI 46 to 88 months) for the other HTRs. CONCLUSIONS: The natural history of AAA in HTR is characterized by an increased expansion rate. Male HTR with end-stage IHD are particularly at risk and should be closely followed-up after HT.

Gliflozins (sodium-glucose cotransporter type 2 inhibitors or SGLT2is) reduced hospitalisations for heart failure in all large prospective cardiovascular outcome trials performed in patients with type 2 diabetes at risk of cardiovascular disease. This protective effect was confirmed in two dedicated trials that specifically targeted patients with heart failure and reduced left ventricular ejection fraction (DAPA-HF with dapagliflozin and EMPEROR-reduced with empagliflozin) and in two trials in patients with preserved left ventricular ejection fraction (EMPEROR-preserved with empagliflozin and DELIVER with dapagliflozin), independently of the presence of diabetes. These favourable results contribute to give a privileged position to SGLT2is in recent international guidelines produced by diabetologists and cardiologists.
Les gliflozines (inhibiteurs des cotransporteurs sodium-glucose de type 2 (iSGLT2)) réduisent les hospitalisations pour insuffisance cardiaque (IC) dans tous les grands essais prospectifs chez les patients avec diabète de type 2 à risque cardiovasculaire. Les effets ont été confirmés dans 2 essais ciblant spécifiquement les patients avec IC à fraction d'éjection réduite (DAPA-HF avec la dapagliflozine et EMPEROR-Reduced avec l'empagliflozine) et dans 2 essais chez des patients à fraction d'éjection préservée (EMPEROR-Preserved avec l'empagliflozine et DELIVER avec la dapagliflozine), qu'ils soient diabétiques ou non. Ces résultats favorables ont donné aux iSGLT2 une place privilégiée chez les patients avec IC dans les dernières recommandations internationales de diabétologie et de cardiologie.

BACKGROUND: There are limited data on Coronavirus disease 2019 (COVID-19) in solid organ transplant patients, especially in heart transplant recipients, with only a few case reports and case series described so far. Heart transplant recipients may be at particular high risk due to their comorbidities and immunosuppressed state. CASE PRESENTATION: This report describes the clinical course and the challenging management of early COVID-19 infection in two heart transplant recipients who tested positive for the SARS-CoV-2 virus in the perioperative period of the transplant procedure. The two patients developed a severe form of the disease and ultimately died despite the initiation of an antiviral monotherapy with hydroxychloroquine coupled with the interruption of mycophenolate mofetil. CONCLUSIONS: These two cases illustrate the severity and poor prognosis of COVID-19 in the perioperative period of a heart transplant. Thorough screening of donors and recipients is mandatory, and the issue of asymptomatic carriers needs to be addressed.

Background Previous studies have suggested that exercising may induce cardiac damage. Galectin-3 (Gal-3) and soluble suppression of tumorigenicity 2 (ST2) are very interesting biomarkers for heart failure and myocardial fibrosis. We aimed to compare the kinetics of emerging fibrosis cardiac biomarkers as Gal-3 and ST-2 in endurance runners, and recreational runners before and after a running event represented by a marathon and an ultratrail event. Methods Blood samples were taken from 19 healthy non-elite marathon runners (42 km), 27 ultratour runners (67 km), and 14 recreational runners who represented the control group (10 km) just before the run (T0), just after (T1) and 3 h after (T2), in order to analyze Gal-3, ST2, hsTnT, NT-proBNP, CKMB and hsCRP. We compared the percentage of evolution and the slopes obtained from T0 to T1 (pT0T1) and from T1 to T2 (pT1T2), between the different groups of runners participating in three different races. Results Plasma cardiac biomarker concentrations increased significantly from baseline to immediately post-exercise and most of the time decreased over the subsequent 3-h period. For pT0T1 and pT1T2, the markers Gal-3 and ST2 showed a significant difference between types of run (p < 0.05 and p < 0.0001, respectively). During the recovery time, Gal-3 returned to the baseline values but not ST2 which continued to increase. Conclusions Gal-3 and ST2 are considered as a reflection of cardiac fibrosis and remodeling. The evolution of both was different, particularly after the recovery time. ST2 values exceeding cutoff values at any time.

OBJECTIVES: Ventilator-associated pneumonia diagnosis remains a debatable topic. New definitions of ventilator-associated conditions involving worsening oxygenation have been recently proposed to make surveillance of events possibly linked to ventilator-associated pneumonia as objective as possible. The objective of the study was to confirm the effect of subglottic secretion suctioning on ventilator-associated pneumonia prevalence and to assess its concomitant impact on ventilator-associated conditions and antibiotic use. DESIGN: Randomized controlled clinical trial conducted in five ICUs of the same hospital. PATIENTS: Three hundred fifty-two adult patients intubated with a tracheal tube allowing subglottic secretion suctioning were randomly assigned to undergo suctioning (n = 170, group 1) or not (n = 182, group 2). MAIN RESULTS: During ventilation, microbiologically confirmed ventilator-associated pneumonia occurred in 15 patients (8.8%) of group 1 and 32 patients (17.6%) of group 2 (p = 0.018). In terms of ventilatory days, ventilator-associated pneumonia rates were 9.6 of 1,000 ventilatory days and 19.8 of 1,000 ventilatory days, respectively (p = 0.0076). Ventilator-associated condition prevalence was 21.8% in group 1 and 22.5% in group 2 (p = 0.84). Among the 47 patients with ventilator-associated pneumonia, 25 (58.2%) experienced a ventilator-associated condition. Neither length of ICU stay nor mortality differed between groups; only ventilator-associated condition was associated with increased mortality. The total number of antibiotic days was 1,696 in group 1, representing 61.6% of the 2,754 ICU days, and 1,965 in group 2, representing 68.5% of the 2,868 ICU days (p < 0.0001). CONCLUSIONS: Subglottic secretion suctioning resulted in a significant reduction of ventilator-associated pneumonia prevalence associated with a significant decrease in antibiotic use. By contrast, ventilator-associated condition occurrence did not differ between groups and appeared more related to other medical features than ventilator-associated pneumonia.

BACKGROUND: Heart transplantation (HTx) in adults with congenital heart disease (ACHD) remains challenging because of structural anomalies and often previous procedure. The aim of this retrospective study was to describe the outcomes of heart transplantation (HTx) in a cohort of ACHD patients at our tertiary centre. PATIENTS AND METHODS: Between January 1993 and December 2010, 223 consecutive adult patients (age > 18 years) underwent HTx at our institution. Fifteen (6.7%) were ACHD patients. Outcomes were reviewed using our institution's HTx database. We looked at 30-day, 1, 5 and 10-years survival, as well as post-transplantation complications. RESULTS: The mean age at HTx of the groups of ACHD was 42 ± 14.4 years, vs 54.2 ± 9.8 years for the non-CHD patients. Prior to transplant, thirteen of the fifteen ACHD had undergone one or more surgical procedures including palliative or corrective open-heart procedures in 66.6% of them. Seven of the fifteen ACHD (47%) required additional surgical procedures at transplantation. The mean follow-up was 95,44 ± 84.3 months. There was no significant difference in survival (ACHD vs non-CHD) at 30 days (87% vs. 90%), 1 year (73% vs. 74.5%) or 5 years (53% vs. 55%). Survival at 10 years was respectively 53% and 41% for ACHD patients and non-CHD patients. CONCLUSION: Despite the surgical challenge, HTx in ACHD has a good long-term result. However, the small sample size of our cohort limits any definitive conclusions.

BACKGROUND: When advanced heart failure occurs in cardiac amyloidosis, prognosis is poor. In this setting heart transplantation (HTX) is a treatment option for selected patients. We here present the results of post-transplantation outcomes in cardiac amyloidosis within the Eurotransplant area, investigating possible predictors of survival. METHODS: Of 115 patients undergoing HTX due to cardiac amyloidosis in the Eurotransplant region between November 1987 and May 2020, detailed assessment prior to transplantation was available in 85 patients. The present study was conducted in a retrospective approach. Primary endpoint was mortality after HTX. Baseline variables were entered in a Cox proportional hazards model with the primary endpoint as a dependent variable. RESULTS: Median overall survival following HTX was 6.3 years in the overall collective and the subgroup. Univariate Cox proportional hazards model revealed a significant relationship between overall survival and the transplantation period (2008 to 2020 vs 1987 to 2007; median survival 9.7 years vs 1.8 years, hazard ratio 0.45, p = 0.01). Further predictors were albumin concentration (hazard ratio 0.92, p < 0.001), and systolic blood pressure (hazard ratio 0.96, p < 0.001). The transplant period as well as albumin concentration remained significant independent predictors in the AL sub cohort in a multivariate Cox proportional hazards model. CONCLUSIONS: HTX is a viable treatment option for patients at an advanced stage of cardiac amyloidosis as overall survival after transplantation has improved in the modern age. Patients at a very advanced stage of the disease, indicated by low serum albumin and blood pressure, show worse outcomes following HTX. Optimal timing and careful patient selection may therefore be particularly important to further improve post-HTX survival in amyloidosis patients.

BACKGROUND: Constrictive pericarditis (CP) is a disease characterized by inflammation, progressive fibrosis, and thickening of the pericardium. Constrictive pericarditis after heart transplantation (HT) is a rare phenomenon, with a reported incidence of 1.4-3.9%. It is an important clinical problem which shares similar clinical features with entities such as restrictive cardiomyopathy. Therefore, it poses diagnostic challenges and therapeutic dilemmas even for experienced clinicians. CASE SUMMARY: A 53-year-old patient developed a zoster infection with pericardial effusion 9 months after HT for idiopathic dilated cardiomyopathy. Two months later, he presented with leg oedema and ascites and was treated by diuretics for volume overload. He was readmitted 8 months later with features of right heart failure. Multimodal imaging investigations were suggestive of CP. He successfully recovered after a radical pericardiectomy. DISCUSSION: Constrictive pericarditis is a rare complication in HT. Heart transplant recipients (HTR) with a history of post-operative pericardial effusion, or with rejection episodes are at high risk of developing CP. Differentiating CP from other conditions that cause apparent congestive heart failure in HTR is challenging. Management of CP is mainly surgical pericardiectomy.
RESUMO
AIM: Heart failure (HF) poses a unique medical burden of high morbidity and mortality. Elevated resting heart rate (HR) is associated with worse outcomes in chronic HF, but little is known about the prognostic impact of serial HR measurement during hospital stay after acute HF. We examined the association between HR obtained at admission at Day 4 and at discharge and long-term mortality in a cohort of 672 patients discharge from hospital after management of acute HF. METHODS AND RESULTS: All patients examined were in sinus rhythm. HR was derived from electrocardiogram and was defined as the first reported HR in the medical record. At 1 year follow up, 60 patients died. Median HR was 86 ± 17 b.p.m. (first tertile: 75 b.p.m., third tertile: 97 b.p.m.) at admission, 76 ± 14 b.p.m. (first tertile: 67 b.p.m., third tertile 85 b.p.m.) at Day 4, and 72 ± 11 b.p.m. (first tertile: 64 b.p.m., third tertile 80 b.p.m.) at discharge. Patients who died were significantly older (75 ± 11 vs. 71 ± 12 years; P = 0.027), had more frequently a history of ischemic cardiomyopathy (n = 34/60, P = 0.012) and of chronic obstructive pulmonary disease (n = 26/60, P = 0.027), had higher admission N terminal pro brain natriuretic peptide (14 572 ± 21 600 vs. 7647 ± 7964 pg/ml; P = 0.027), had lower systolic and diastolic blood pressures (P < 0.05), haemoglobin level (10.6 ± 2.2 vs. 12.2 ± 2.2 g/L; P = 0.005), albumin level (35.2 ± 4.3 vs 37.1 ± 4.1 g/dl; P = 0.003) and estimated glomerular filtration rate (47 ± 21 vs. 60 ± 28 ml/min/1.73 m2 ; P = 0.0017). There were no significant differences between survivors and nonsurvivors in left ventricular ejection, the use of beta-blocker and angiotensin-converting enzyme-inhibitor, and the rate of comorbidities (hypertension, diabetes) (P=NS, for all). HR at admission was not significantly associated with 1 year mortality (P = 0.20), whereas there was a significant increase in 1 year mortality for HRs>85 b.p.m. at Day 4 (P < 0.0001) and > 80 b.p.m. at discharge (P < 0.0001). In the multivariable model that included the third tertile at Day 4 and discharge HR and adjusted for all other significant covariates, haemoglobin (P = 0.019), and HR at Day 4 (P = 0.023) were independently associated with 1 year mortality. When only discharge HR was included haemoglobin (P = 0.0004) and HR at discharge (P = 0.00053) remained independently associated with 1 year mortality. CONCLUSIONS: In patients surviving the acute HF phase, a high HR at Day 4, and at a lesser degree at discharge, but not at admission, is a strong predictor of 1 year mortality.

AIMS: The present study sought to assess the impact of aortic stenosis (AS) on myocardial function as assessed by layer-specific longitudinal strain (LS) and its relationship with symptoms and outcome. METHODS AND RESULTS: We compared 211 patients (56% males, mean age 73 ± 12 years) with severe AS and left ventricular ejection fraction (LVEF) ≥50% (114 symptomatic, 97 asymptomatic) with 50 controls matched for age and sex. LS was assessed from endocardium, mid-myocardium, and epicardium by 2D speckle-tracking echocardiography. Despite similar LVEF, multilayer strain values were significantly lower in symptomatic patients, compared to asymptomatic and controls [global LS: 17.9 ± 3.4 vs. 19.1 ± 3.1 vs. 20.7 ± 2.1%; endocardial LS: 20.1 ± 4.9 vs. 21.7 ± 4.2 vs. 23.4 ± 2.5%; epicardial LS: 15.8 ± 3.1 vs. 16.8 ± 2.8 vs. 18.3 ± 1.8%; P < 0.001 for all]. On multivariable logistic regression analysis, endocardial LS was independently associated to symptoms (P = 0.012), together with indexed left atrial volume (P = 0.006) and LV concentric remodelling (P = 0.044). During a mean follow-up of 22 months, 33 patients died of a cardiovascular event. On multivariable Cox-regression analysis, age (P = 0.029), brain natriuretic peptide values (P = 0.003), LV mass index (P = 0.0065), LV end-systolic volume (P = 0.012), and endocardial LS (P = 0.0057) emerged as independently associated with cardiovascular death. The best endocardial LS values associated with outcome was 20.6% (sensitivity 70%, specificity 52%, area under the curve = 0.626, P = 0.022). Endocardial LS (19.1 ± 3.3 vs. 20.7 ± 3.3, P = 0.02) but not epicardial LS (15.2 ± 2.8 vs. 15.9 ± 2.5, P = 0.104) also predicted the outcome in patients who were initially asymptomatic. CONCLUSION: In patients with severe AS, LS impairment involves all myocardial layers and is more prominent in the advanced phases of the disease, when the symptoms occur. In this setting, the endocardial LS is independently associated with symptoms and patient outcome.

AIMS: The present study sought to evaluate the correlation between indices of non-invasive myocardial work (MW) and left ventricle (LV) size, traditional and advanced parameters of LV systolic and diastolic function by 2D echocardiography (2DE). METHODS AND RESULTS: A total of 226 (85 men, mean age: 45 ± 13 years) healthy subjects were enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study. Global work index (GWI), global constructive work (GCW), global work waste (GWW), and global work efficiency (GWE) were estimated from LV pressure-strain loops using custom software. Peak LV pressure was estimated non-invasively from brachial artery cuff pressure. LV size, parameters of systolic and diastolic function and ventricular-arterial coupling were measured by echocardiography. As advanced indices of myocardial performance, global longitudinal strain (GLS), global circumferential strain (GCS), and global radial strain (GRS) were obtained. On multivariable analysis, GWI was significantly correlated with GLS (standardized beta-coefficient = -0.23, P < 0.001), ejection fraction (EF) (standardized beta-coefficient = 0.15, P = 0.02), systolic blood pressure (SBP) (standardized beta-coefficient = 0.56, P < 0.001) and GRS (standardized beta-coefficient = 0.19, P = 0.004), while GCW was correlated with GLS (standardized beta-coefficient = -0.55, P < 0.001), SBP (standardized beta-coefficient = 0.71, P < 0.001), GRS (standardized beta-coefficient = 0.11, P = 0.02), and GCS (standardized beta-coefficient = -0.10, P = 0.01). GWE was directly correlated with EF and inversely correlated with Tei index (standardized beta-coefficient = 0.18, P = 0.009 and standardized beta-coefficient = -0.20, P = 0.004, respectively), the opposite occurred for GWW (standardized beta-coefficient =--0.14, P = 0.03 and standardized beta-coefficient = 0.17, P = 0.01, respectively). CONCLUSION: The non-invasive MW indices show a good correlation with traditional 2DE parameters of myocardial systolic function and myocardial strain.

The functional integrity of the endothelium is essential for vascular health. In addition to maintaining a delicate balance between vasodilation and vasoconstriction, the endothelium has numerous other complex roles involved in the maintenance of vascular homeostasis. Chronic exposure to cardiovascular risk factors and oxidative stress results in an imbalance in these functions, creating an environment that favors reduced vasodilation and a proinflammatory and prothrombic state. The involvement of endothelial dysfunction in all stages of the cardiovascular continuum makes it an important target for treatment. One of the major endothelial-derived factors involved in the maintenance of endothelial function is nitric oxide (NO). Angiotensin-converting enzyme (ACE) inhibitors increase NO production both directly and indirectly by preventing production of angiotensin II (which diminishes NO production) and inhibiting the degradation of bradykinin (which stimulates local release of NO). Among the ACE inhibitors, perindopril appears to have the greatest effects on bradykinin and has demonstrated efficacy in a number of markers of endothelial dysfunction including arterial stiffness and progression of atherosclerosis. There is also strong evidence supporting the use of perindopril-based therapy for the treatment of hypertension and for reducing the risk of cardiovascular morbidity and mortality in a wide range of patients across the cardiovascular continuum.Funding: The journal's Rapid Service Fee was funded by Servier.
RESUMO
Objective: Hypoalbuminemia is common in heart failure (HF), especially in elderly patients. It is associated with an increased risk of death. The present study sought to examine the prognostic significance of serum albumin level in the prediction of long-term mortality in patients admitted for acute HF.Methods and results: We examined the association between albumin and hospital mortality in a cohort of 509 patients admitted for acute HF. None of the patients had infectious disease, severe arrhythmias (atrial fibrillation, ventricular tachycardia, ventricular fibrillation), required invasive ventilation or presented with acute coronary syndrome or primary valvular disease. Sixty-nine patients (14%) died during the 1-year follow-up. With multivariable analysis, haemoglobin level (p = .003), systolic blood pressure (p = .004) and serum albumin level (p = .003) emerged as independent predictors of long-term mortality. Hypoalbuminemia (<35.7 g/L) had a hazard ratio of 2.01 (95% CI 1.24-3.25) and haemoglobin of 2.6 (95% CI 1.29-5.22) for predicting long-term mortality.Conclusions: Serum albumin level measured at admission, especially if combined with anaemia, can serve as a simple prognostic factor in acute HF for predicting long-term outcome.

Heart transplantation (HT) from donation after circulatory death (DCD) is a promising alternative to expand the heart donor pool. Cold storage can be used in a strategy to successfully retrieve and transplant DCD hearts after reconditioning using normothermic regional perfusion for distant procurement. Herein, we present the first report of a pediatric DCD heart reconditioned with normothermic regional perfusion, preserved using only cold storage while being transported to a neighboring center, and then successfully transplanted after nearly 2 hours of cold static storage. If supported by an appropriate trial, this finding could obviate the need to use expensive perfusion devices for short interhospital distances for DCD heart transportation and stimulate more centers across the world to embrace DCD HT.

BACKGROUND: Previously, we showed that B-type natriuretic peptide (BNP) measured in the donor was related to cardiac performance after cardiac transplantation. The present study assesses the value of 3 biomarkers in the selection of donor hearts in a larger cohort. METHODS: Blood samples were prospectively obtained in 105 brain-dead patients scheduled for heart donation. BNP, soluble suppressor of tumorigenicity 2 (ST2), and troponin of heart donors were correlated with hemodynamic parameters early after transplantation as well as with the mortality of the recipients. RESULTS: A significant inverse relationship was found between donor BNP measured at the time of donation and recipient cardiac index and cardiac output at day 13 post-transplantation (r = -0.31, P = .005, and r = -0.34, P = .0016, respectively). Logistic regression analysis-including BNP, ST2, and troponin-showed that donor BNP was a predictor of a poor cardiac index (< 2.2 L/min/m2) in the recipient (P = .04). A donor BNP > 132 pg/mL has a sensitivity of 56% (95% confidence interval 21-86) and a specificity of 86% (95% confidence interval 77-93) to predict poor cardiac performance in the recipient. When the donor BNP is ≤ 132 pg/mL, the risk of a poor cardiac function in the recipient is very low (negative predictive value 94%). Mortality at 30 days was also correlated to donor BNP (r = 0.29, P = .0029). Long-term survival of the recipient was not correlated to the biomarkers measured in the donor. CONCLUSION: Donor BNP, but not donor ST2 or high-sensitivity troponin, provides information on the donor heart and early post-transplant performance, including 1-month mortality.
