International audience; Rationale: The relationship between the initial treatment strategy and survival in pulmonary arterial hypertension (PAH) remains uncertain. Objectives: To evaluate the long-term survival of patients with PAH categorized according to the initial treatment strategy. Methods: A retrospective analysis of incident patients with idiopathic, heritable, or anorexigen-induced PAH enrolled in the French Pulmonary Hypertension Registry (January 2006 to December 2018) was conducted. Survival was assessed according to the initial strategy: monotherapy, dual therapy, or triple-combination therapy (two oral medications and a parenteral prostacyclin). Measurements and Main Results: Among 1,611 enrolled patients, 984 were initiated on monotherapy, 551 were initiated on dual therapy, and 76 were initiated on triple therapy. The triple-combination group was younger and had fewer comorbidities but had a higher mortality risk. The survival rate was higher with the use of triple therapy (91% at 5 yr) as compared with dual therapy or monotherapy (both 61% at 5 yr) (P < 0.001). Propensity score matching of age, sex, and pulmonary vascular resistance also showed significant differences between triple therapy and dual therapy (10-yr survival, 85% vs. 65%). In high-risk patients (n = 243), the survival rate was higher with triple therapy than with monotherapy or dual therapy, whereas there was no difference between monotherapy and double therapy. In intermediate-risk patients (n = 1,134), survival improved with an increasing number of therapies. In multivariable Cox regression, triple therapy was independently associated with a lower risk of death (hazard ratio, 0.29; 95% confidence interval, 0.11-0.80; P = 0.017). Among the 148 patients initiated on a parenteral prostacyclin, those on triple therapy had a higher survival rate than those on monotherapy or dual therapy. Conclusions: Initial triple-combination therapy that includes parenteral prostacyclin seems to be associated with a higher survival rate in PAH, particularly in the youngest high-risk patients.

Common variable immunodeficiency (CVID) is known to cause infectious, inflammatory, and autoimmune manifestations. Pulmonary hypertension (PH) is an unusual complication of CVID with largely unknown characteristics and mechanisms. We report the clinical, functional, hemodynamics, radiologic and histologic characteristics, and outcomes of CVID-associated PH patients from the French PH Network. Ten patients were identified. The median (range) age at CVID diagnosis was 36.5 (4–49) years and the median delay between CVID and PH diagnosis was 12 (0–30) years. CVID-associated PH affected predominantly women (female-to-male ratio 9:1). Most patients were New York Heart Association functional class III with a severe hemodynamic profile and frequent portal hypertension (n = 6). Pulmonary function tests were almost normal in 70% of patients and showed a mild restrictive syndrome in 30% of patients while the diffusing capacity for carbon monoxide was decreased in all but one patient. High-resolution computed tomography found enlarged mediastinal nodes, mild interstitial infiltration with reticulations and nodules. Two patients had a CIVD-interstitial lung disease, and one presented with bronchiectasis. Pathologic assessment of lymph nodes performed in 5 patients revealed the presence of granulomas (n = 5) and follicular lymphoid hyperplasia (n = 3). At last follow-up (median 24.5 months), 9 patients were alive, and one patient died of Hodgkin disease. PH is a possible complication of CVID whose pathophysiological mechanisms, while still unclear, would be due to the inflammatory nature of CVID. CVID-associated PH presents as precapillary PH with multiple possible causes, acting in concert in some patients: a portal hypertension, a pulmonary vascular remodeling, sometimes a pulmonary parenchymal involvement and occasionally an extrinsic compression by mediastinal lymphadenopathies, which would be consistent with its classification in group 5 of the current PH classification.

OBJECTIVES: The objectives were to compare clinical pharmacist interventions between two care groups: COVID-19-positive and COVID-19-negative patients, and to identify drugs that require particular attention, especially those involved in COVID-19 management. METHODS: A prospective cohort study was conducted on patients with positive and negative COVID-19 statuses admitted to Lille University Hospital over 1 month. Pharmaceutical analysis instigated interventions to rectify drug-related errors. For each pharmaceutical intervention (PI), the anatomical therapeutic chemical classification of the drug and the outcome of such an intervention were specified. RESULTS: The study included 438 patients. Prescription analysis led to 188 PIs performed on 118 patients (64 COVID-19-positive patients and 54 COVID-19-negative patients). Most drug-related problems were incorrect dosage representing 36.7% (69/188) of all interventions: 27.9% (29/104) for the COVID-19-positive group and 47.6% (40/84) for the COVID-19-negative group. The most frequent PI in 34% (64/188) of cases was terminating a drug: 27.9% (29/104) for the COVID-19-positive group and 47.6% (40/84) for the COVID-19-negative group. The main drug classes involved were antithrombotic agents (20.7%, 39/188), antibacterials for systemic use (13.8%, 26/188) and drugs for gastric acid-related disorders (6.4%, 12/188). Study population was limited to a single centre over 1 month. CONCLUSION: No difference in PI was noted between the two groups. The presence of pharmacists led to a reduction in drug-related prescription problems, especially for antithrombotic and antibacterial drugs for both groups. Clinical pharmacy commitment in such a pandemic is therefore important.

Aims Major bleeding events in heart failure (HF) patients are poorly described. We sought to investigate the importance of major bleeding and its impact on outcomes in HF patients. Methods and results We analysed incident bleeding and ischaemic events during a 3 year follow‐up in 2910 HF outpatients included in a prospective multicentre registry. Major bleeding was defined as a Type ≥3 bleed using the Bleeding Academic Research Consortium definition. Ischaemic event was a composite of ischaemic stroke and myocardial infarction. Events were adjudicated by a blinded committee. At inclusion, most patients (89%) received at least one antithrombotic: anticoagulation (53.9%) and/or antiplatelet therapy (46.2%). Bleeding occurred in 111 patients {3 year cumulative incidence: 3.6% [95% confidence interval (CI) 3.0–4.3]} and ischaemic events in 102 patients [3 year cumulative incidence: 3.3% (95% CI 2.7–4.0)]. Most bleedings were Bleeding Academic Research Consortium 3a (32.5%) or 3b (31.5%). Most frequent sites of bleeding were gastrointestinal (40.6%) and intracranial (27.9%). Variables associated with bleeding were atrial fibrillation [hazard ratio (HR) = 2.63 (95% CI 1.66–4.19), P

Background & Aims Long-term outcomes in portopulmonary hypertension (PoPH) are poorly studied in the current era of pulmonary hypertension management. We analysed the effect of pulmonary arterial hypertension (PAH)-targeted therapies, survival and predictors of death in a large contemporary cohort of patients with PoPH. Methods Data from patients with PoPH consecutively enrolled in the French Pulmonary Hypertension Registry between 2007 and 2017 were collected. The effect of initial treatment strategies on functional class, exercise capacity and cardiopulmonary haemodynamics were analysed. Survival and its association with PAH- and hepatic-related characteristics were also examined. Results Six hundred and thirty-seven patients (mean age 55 ± 10 years; 58% male) were included. Fifty-seven percent had mild cirrhosis, i.e. Child-Pugh stage A. The median model for end-stage liver disease (MELD) score was 11 (IQR 9–15). Most patients (n = 474; 74%) were initiated on monotherapy, either with a phosphodiesterase-5 inhibitor (n = 336) or with an endothelin-receptor antagonist (n = 128); 95 (15%) were initiated on double oral combination therapy and 5 (1%) on triple therapy. After a median treatment time of 4.5 months, there were significant improvements in functional class (p Conclusion Survival of patients with PoPH is strongly associated with the severity of liver disease. Patients who underwent liver transplantation had the best long-term outcomes. Lay summary Portopulmonary hypertension is defined by the presence of pulmonary arterial hypertension in the context of chronic liver disease and is characterized by progressive shortness of breath and exercise limitation. The presence of severe pulmonary arterial hypertension in liver transplant candidates represents a contraindication for such a surgery; however, treatments targeting pulmonary arterial hypertension are efficacious, allowing for safe transplantation and conferring good survival outcomes in those who undergo liver transplantation.

Background: Heart failure (HF) remains a main cause of mortality worldwide. Risk stratification of patients with systolic chronic HF is critical to identify those who may benefit from advanced HF therapies. The aim of this study is to identify plasmatic proteins that could predict early death of HF patients. Methods: The subproteome targeted by the aptamer-based assay (SOMAscan) of 1310 proteins was profiled in blood samples from 168 HF patients with reduced ejection fraction hospitalized in CHRU de Lille. Patient's outcome was assessed 3 years after inclusion. Findings: Among the 1310 proteins, 203 were significantly modulated between dead and alive patients (Wilcoxon tests, FDR 5%). The INCA molecular network was built using these 203 proteins and contained 2881 molecules (1639 proteins, 1072 microRNAs, 170 metabolites). To assess mechanistic context of HF, molecules were assigned to 34 clusters annotated to biological pathways from Gene Ontology. Analysis of the INCA network model allowed to highlight extracellular matrix organization as mechanism involved in HF. In parallel, an adaptive LASSO was performed on these 203 proteins and six proteins were selected as candidates to predict early death of HF patients: complement C3, cathepsin S and FAM107B were decreased and MAPKAPK5, MMP1 and MMP7 increased in dead patients compared with patients alive. By conventional assays, complement C3, MMP1 and MMP7 were validated but not cathepsin S due to the low sensitivity and specificity of the assay used. Interpretation: A proteomic signature of 6 plasma proteins allows identifying HF patients with a risk of early death.

International audience; Introduction The significant morbidity and mortality in patients with heart failure (HF), notably in the most advanced forms of the disease, justify the need for novel therapeutic options. In the last year, the soluble guanylate cyclase (sGC) stimulator, vericiguat, has drawn the attention of the medical community following the report of reduced clinical outcomes in patients with worsening chronic HF (WCHF).Areas Covered The authors review the available data on the mechanism of action of vericiguat (cyclic guanosine monophosphate (cGMP) pathway), its clinical development program, its role in HF management, and its future positioning in the therapeutic recommendations.Expert opinion cGMP deficiency has deleterious effects on the heart and contributes to the progression of HF. Different molecules, including nitric oxide (NO) donors, phosphodiesterase inhibitors, and natriuretic peptides analogues, target the NO-sCG-cGMP pathway but have yielded conflicting results in HF patients. Vericiguat acts as a sGC stimulator thus targeting the NO-sGC-cGMP pathway by a different mechanism that complements the current pharmacotherapy for HF. Vericiguat has shown an additional statistical add-on therapy efficacy by reducing morbi-mortality in patients with WCHF. A better evaluation of HF severity might be an important determinant to guide the use of vericiguat among the available therapies.

We lack recent data on the incidence, correlates, and prognosis associated with heart failure (HF) development in patients with stable coronary artery disease (CAD). Here, we analyzed HF development in a contemporary population of outpatients with stable CAD.Of 4184 unselected outpatients with stable CAD (ie, myocardial infarction [MI] and/or coronary revascularization1 year earlier) included in the multicenter CORONOR registry, we identified 3871 patients with no history of hospitalization for HF at inclusion and followed 3785 (98%) of them for 5 years. During follow-up, 211 patients were hospitalized for HF (5-year cumulative incidence 5.7%) and 163 patients had incident MIs. Independent predictors of hospitalization for HF were older age, lower left ventricular ejection fraction (LVEF), atrial fibrillation, higher body mass index, diabetes mellitus, history of hypertension, angina at inclusion, and multivessel CAD. Most hospitalizations for HF (62.6%) occurred in patients with LVEF ≥50% at inclusion, and most (92.4%) were not preceded by an incident MI. Hospitalization for HF was a powerful predictor of mortality (adjusted hazard ratio 5.97, 95% confidence interval 4.55-7.83; P.0001). After hospitalization for HF, mortality rates were similar in patients with LVEFs ≥50% and50% at hospitalization.Outpatients with stable CAD were frequently hospitalized for HF, and HF was associated with high mortality. Most HF hospitalizations were associated with preserved LVEF at inclusion and were not preceded by an incident MI.

Aims Our objective was to better understand the genetic bases of dilated cardiomyopathy (DCM), a leading cause of systolic heart failure. Methods and results We conducted the largest genome-wide association study performed so far in DCM, with 2719 cases and 4440 controls in the discovery population. We identified and replicated two new DCM-associated loci on chromosome 3p25.1 [lead single-nucleotide polymorphism (SNP) rs62232870, P = 8.7 × 10−11 and 7.7 × 10−4 in the discovery and replication steps, respectively] and chromosome 22q11.23 (lead SNP rs7284877, P = 3.3 × 10−8 and 1.4 × 10−3 in the discovery and replication steps, respectively), while confirming two previously identified DCM loci on chromosomes 10 and 1, BAG3 and HSPB7. A genetic risk score constructed from the number of risk alleles at these four DCM loci revealed a 3-fold increased risk of DCM for individuals with 8 risk alleles compared to individuals with 5 risk alleles (median of the referral population). In silico annotation and functional 4C-sequencing analyses on iPSC-derived cardiomyocytes identify SLC6A6 as the most likely DCM gene at the 3p25.1 locus. This gene encodes a taurine transporter whose involvement in myocardial dysfunction and DCM is supported by numerous observations in humans and animals. At the 22q11.23 locus, in silico and data mining annotations, and to a lesser extent functional analysis, strongly suggest SMARCB1 as the candidate culprit gene. Conclusion This study provides a better understanding of the genetic architecture of DCM and sheds light on novel biological pathways underlying heart failure.

International audience; Purpose: Risk stratification in chronic systolic heart failure (HF) is critical to identify the patients who may benefit from advanced therapies. It is aimed at identifying new biomarkers to improve prognosis evaluation and help to better understand HF physiopathology.Experimental design: Prognostic evaluation is performed in 198 patients with chronic systolic HF: 99 patients who died from cardiovascular cause within three years are individually matched for age, sex, and HF etiology (ischemic vs not) with 99 patients who are alive after three years of HF evaluation. A proteomic profiling of 15 apolipoproteins (Apo) is performed: Apo-A1, -A2, -A4, -B100, -C1, -C2, -C3, -C4, -D, -E, -F, -H, -J, -L1, and -M using LC-MRM-MS.Results: In univariate analysis, the levels of Apo-B100 and -L1 are significantly lower and the levels of Apo-C1, -J, and -M are significantly higher in patients who died from cardiovascular cause as compared with patients alive. In the final statistical model, Apo-C1, Apo-J, and Apo-M improve individually the prediction of cardiovascular death. Ingenuity pathway analysis indicates these three Apo in a network associated with lipid metabolism, atherosclerosis signaling, and retinoid X receptor activation.Conclusions: Proteomic profiling of apolipoproteins using LC-MRM-MS might be useful in clinical practice for risk stratification of HF patients.

To evaluate the concordance between DECT perfusion and ventilation/perfusion (V/Q) scintigraphy in diagnosing chronic thromboembolic pulmonary hypertension (CTEPH). Eighty patients underwent V/Q scintigraphy and DECT perfusion on a 2nd- and 3rd-generation dual-source CT system. The imaging criteria for diagnosing CTEPH relied on at least one segmental triangular perfusion defect on DECT perfusion studies and V/Q mismatch on scintigraphy examinations. Based on multidisciplinary expert decisions that did not include DECT perfusion, 36 patients were diagnosed with CTEPH and 44 patients with other aetiologies of PH. On DECT perfusion studies, there were 35 true positives, 6 false positives and 1 false negative (sensitivity 0.97, specificity 0.86, PPV 0.85, NPV 0.97). On V/Q scans, there were 35 true positives and 1 false negative (sensitivity 0.97, specificity 1, PPV 1, NPV 0.98). There was excellent agreement between CT perfusion and scintigraphy in diagnosing CTEPH (kappa value 0.80). Combined information from DECT perfusion and CT angiographic images enabled correct reclassification of the 6 false positives and the unique false negative case of DECT perfusion. There is excellent agreement between DECT perfusion and V/Q scintigraphy in diagnosing CTEPH. The diagnostic accuracy of DECT perfusion is reinforced by the morpho-functional analysis of data sets. • Chronic thromboembolic pulmonary hypertension (CTEPH) is potentially curable by surgery. • The triage of patients with pulmonary hypertension currently relies on scintigraphy. • Dual-energy CT (DECT) can provide standard diagnostic information and lung perfusion from a single acquisition. • There is excellent agreement between DECT perfusion and scintigraphy in separating CTEPH and non-CTEPH patients.

Assessment of potential donors is an essential part of heart transplantation. Despite the shortage of donor hearts, donor heart procurement from brain-dead organ donors remains low in France, which may be explained by the increasing proportion of high-risk donors, as well as the mismatch between donor assessment and the transplant team's expectations. Improving donor and donor heart assessment is essential to improve the low utilization rate of available donor hearts without increasing post-transplant recipient mortality. This document provides information to practitioners involved in brain-dead donor management, evaluation and selection, concerning the place of medical history, electrocardiography, cardiac imaging, biomarkers and haemodynamic and arrhythmia assessment in the characterization of potential heart donors.

Importance Modern data regarding incidence and modes of death of patients with aortic stenosis (AS) are restricted to tertiary centers or studies of aortic valve replacement (AVR). Objective To provide new insights into the natural history of outpatients with native AS based on a large regionwide population study with inclusion by all cardiologists regardless of their mode of practice. Design, Setting, and Participants Between May 2016 and December 2017, consecutive outpatients with mild (peak aortic velocity, 2.5-2.9 m/s), moderate (peak aortic velocity, 3-3.9 m/s), and severe (peak aortic velocity, ≥4 m/s) native AS graded by echocardiography were included by 117 cardiologists from the Nord-Pas-de-Calais region in France. Analysis took place between August and November 2020. Main Outcomes and Measures Natural history, need for AVR, and survival of patients with AS were followed up. Indications for AVR were based on current guideline recommendations. Results Among 2703 patients (mean [SD] age, 76.0 [10.8] years; 1260 [46.6%] women), 233 (8.6%) were recruited in a university public hospital, 757 (28%) in nonuniversity public hospitals, and 1713 (63.4%) by cardiologists working in private practice. A total of 1154 patients (42.7%) had mild, 1122 (41.5%) had moderate, and 427 (15.8%) had severe AS. During a median (interquartile range) of 2.1 (1.4-2.7) years, 634 patients underwent AVR and 448 died prior to AVR. Most deaths were cardiovascular (200 [44.7%]), mainly associated with congestive heart failure (101 [22.6%]) or sudden death (60 [13.4%]). Deaths were noncardiovascular in 186 patients (41.5%) and from unknown causes in 62 patients (13.8%). Compared with patients with mild AS, there was increased cardiovascular mortality in those with moderate (hazard ratio, 1.47 [95% CI, 1.07-2.02]) and severe (hazard ratio, 3.66 [95% CI, 2.52-5.31]) AS. The differences remained significant when adjusted for baseline characteristics or in time-dependent analyses considering AS progression. In asymptomatic patients, moderate and mild AS were associated with similar cardiovascular mortality (hazard ratio, 0.99 [95% CI, 0.44-2.21]). Conclusions and Relevance While patients in this study with moderate AS had a slightly higher risk of cardiovascular death than patients with mild AS, this risk was much lower than that observed in patients with severe AS. Moreover, in asymptomatic patients, moderate and mild AS were associated with similar cardiovascular mortality.

IntroductionContemporary risk assessment tools categorise patients with pulmonary arterial hypertension (PAH) as low, intermediate or high risk. A minority of patients achieve low risk status with most remaining intermediate risk. Our aim was to validate a four-stratum risk assessment approach categorising patients as low, intermediate-low, intermediate-high or high risk, as proposed by the Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension (COMPERA) investigators.MethodsWe evaluated incident patients from the French PAH Registry and applied a four-stratum risk method at baseline and at first reassessment. We applied refined cut-points for three variables: World Health Organization functional class, 6-min walk distance and N-terminal pro-brain natriuretic peptide. We used Kaplan–Meier survival analyses and Cox proportional hazards regression to assess survival according to three-stratum and four-stratum risk approaches.ResultsAt baseline (n=2879), the four-stratum approach identified four distinct risk groups and performed slightly better than a three-stratum method for predicting mortality. Four-stratum model discrimination was significantly higher than the three-stratum method when applied during follow-up and refined risk categories among subgroups with idiopathic PAH, connective tissue disease-associated PAH, congenital heart disease and portopulmonary hypertension. Using the four-stratum approach, 53% of patients changed risk category from baseline compared to 39% of patients when applying the three-stratum approach. Those who achieved or maintained a low risk status had the best survival, whereas there were more nuanced differences in survival for patients who were intermediate-low and intermediate-high risk.ConclusionsThe four-stratum risk assessment method refined risk prediction, especially within the intermediate risk category of patients, performed better at predicting survival and was more sensitive to change than the three-stratum approach.

Summary Background The effectiveness of transitional care services for patients discharged from hospital after acute heart failure is challenging, especially in terms of reducing subsequent heart failure hospitalizations. The increased adoption of smartphone applications in society offers a new opportunity to interact with patients to avoid rehospitalization. Thus, electronic health (e-health) can enhance the impact of existing therapeutic education programmes. Aims To determine the prevalence of smartphone use among patients with chronic heart failure, and to assess the epidemiological characteristics and therapeutic management of these patients, with a broader aim of developing smartphone-based therapeutic education programmes for patients. Methods The French Observatoire francais de l’insuffisance cardiaque et du sel (OFICSel) registry was conducted in 2017 by 300 cardiologists, and included both inpatients and outpatients who had been hospitalized for heart failure at least once in the previous 5 years. Data collection included demographic and heart failure-related variables, which were provided by the cardiologist and by the patient via a questionnaire. Results Among the 2822 patients included, 2517 completed the questionnaire. Of this total, 907 patients (36%) were smartphone users. Compared with non-users, smartphone users were younger, were more frequently men, more frequently lived in cities, had a higher educational level and were more frequently professionally active. Smartphone users less frequently had diabetes, hypertension, atrial fibrillation or ischaemic cardiopathy. Only 22% of patients were actively participating in a therapeutic education programme. Conclusion Smartphones were used by more than one-third of patients with heart failure in France in 2017, underscoring the feasibility of developing a smartphone application to deliver therapeutic education to the population with chronic heart failure.

Background: Medical therapy with riociguat and balloon pulmonary angioplasty (BPA) are two therapeutic options for inoperable chronic thromboembolic pulmonary hypertension (CTEPH). Controlled studies comparing these two treatments are lacking. Methods: The multicenter, randomised, controlled RACE trial evaluated the efficacy and safety of riociguat versus BPA in newly diagnosed and treatment-naive patients with CTEPH adjudicated as inoperable. Patients identified as WHO functional class (FC) I-IV with a pulmonary vascular resistance (PVR) >320 dyn.s/cm5 were randomly assigned, in a 1:1 ratio, to receive a treatment with riociguat or BPA. The primary endpoint was resting PVR at week 26, expressed as percentage of PVR at baseline. Secondary endpoints included changes from baseline in 6-min walk distance (6MWD), WHO FC, NT-proBNP, time to clinical worsening, and safety. Results: Between January 2016 and January 2019, 105 patients were randomised in 14 centers belonging to the French Pulmonary Hypertension Network: 53 to riociguat, 52 to BPA. Baseline characteristics are depicted in the table. The full study results will be available in June 2019. Conclusion: RACE study will provide important informations on the effect of riociguat compared to that of BPA as first-line therapy in treatment-naive patients with inoperable CTEPH.

No dedicated randomised clinical trials have evaluated therapies for pulmonary arterial hypertension in patients with portopulmonary hypertension. The endothelin receptor antagonist macitentan has demonstrated long-term efficacy in pulmonary arterial hypertension with a good hepatic safety profile. We aimed to evaluate efficacy and safety of macitentan in patients with portopulmonary hypertension.PORTICO was a phase 4 study done in 36 centres in seven countries, consisting of a 12-week double-blind period (randomly assigned 1:1 to macitentan 10 mg or placebo once daily) followed by a 12-week open-label period. Adults (≥18 years) with portopulmonary hypertension, a 6-minute walk distance of 50 m or more, and with pulmonary vascular resistance of 320 dyn·s·cmBetween June 23, 2015, and July 28, 2017, 85 patients were randomly assigned to macitentan (n=43) or placebo (n=42). At baseline, 54 (64%) were receiving background therapy for pulmonary arterial hypertension. Most patients were WHO functional class II (50, 59%) or III (33, 39%) with a mean 6-minute walk distance of 384·5 m (SD 103·9). At week 12, the geometric mean ratio of baseline pulmonary vascular resistance was 0·63 (95% CI 0·58-0·67) in the macitentan group and 0·98 (95% CI 0·91-1·05) in the placebo group, corresponding to a ratio of geometric mean for pulmonary vascular resistance of 0·65 (95% CI 0·59-0·72, p0·0001), which in turn represented a 35% (95% CI 28-41) reduction in pulmonary vascular resistance with macitentan versus placebo. During the double-blind period, 36 (84%) macitentan-treated and 33 (79%) placebo-treated patients had adverse events, and nine (21%) and six (14%), had serious adverse events. Four (9%) macitentan-treated patients had an adverse event leading to discontinuation versus none in the placebo group. The most frequent adverse event during the double-blind period was peripheral oedema (11 [26%] in the macitentan group and five [12%] in the placebo group).Macitentan significantly improved pulmonary vascular resistance in portopulmonary hypertension patients, with no hepatic safety concerns.Actelion Pharmaceuticals Ltd.

Background To date, nothing is known about the evolution of survival in systemic sclerosis-associated pulmonary arterial hypertension (PAH) over the last decade. Methods This study used a multivariate Cox regression model adjusted for clinically relevant baseline confounders to assess the association between the occurrence of death and date of PAH diagnosis comparing two periods of the same duration (2006-2011 vs 2012-2017). Interactions between the two diagnosis periods and baseline variables were tested. Results A total of 306 incident patients were included, 167 (54.6%) with a PAH diagnosis occurring in 2006 to 2011 and 139 (45.4%) in 2012 to 2017. No significant difference in survival was observed between patients diagnosed with PAH in 2012 to 2017 compared with those diagnosed in 2006 to 2011 (hazard ratio [HR], 0.76 [0.46-1.26]; P = .29). A significant interaction was observed between PAH diagnosis periods and age (P = .05). When stratifying according to age (based on the median age of 70 years), a significant increase was observed in survival in patients aged ≤ 70 years between the 2006 to 2011 period and the 2012 to 2017 period (HR, 0.40 [0.17-0.99]; P = .046) but not in older patients (HR, 1.29 [0.67-2.51]; P = .44). A significantly higher proportion of initial (ie, within the first 4 months) endothelin receptor antagonist/phosphodiesterase type 5 inhibitor combination therapy was observed in younger patients diagnosed from 2012 to 2017 vs those diagnosed from 2006 to 2011 (42.9% vs 19.5%; P = .002) but not in older patients. Conclusions Over the period 2006 to 2017, survival in systemic sclerosis-associated PAH improved over time in patients aged ≤ 70 years but not in older patients. Further investigations are needed to confirm this relation, as general improvement in medical care and management may also be a possible explanation.

A 72-year-old woman with history of breast cancer only treated surgically was referred to our department for pulmonary hypertension (PH) suspicion. Echocardiogram revealed elevated right ventricular systolic pressure. Computed tomography (CT) angiogram showed no pulmonary embolism (PE), but lung scan revealed two ventilation-perfusion mismatch areas. Right cardiac catheterization established precapillary PH. Despite treatment with PH specific therapy (sildenafil, ambrisentan, and epoprostenol), her condition worsened rapidly with acute right heart failure (RHF). She died 22 days after admission. Post-mortem microscopic examination showed a rare combination of PH etiologies consistent with metastasis of breast cancer in pulmonary vasculature including the rare pulmonary tumour thrombotic microangiopathy (PTTM).

Efficacy and safety of macitentan were assessed in patients with portopulmonary hypertension (PoPH) in a 12-week, randomised, double-blind trial (PORTICO; NCT02382016). Patients were randomised to macitentan 10mg (N=43) or placebo (N=42); 51.8% were male, 63.5% were receiving pulmonary arterial hypertension therapy and 58.8% were WHO functional class (FC) II. Mean±SD 6-minute walk distance (6MWD) was 385±104m. At Week 12 macitentan significantly improved pulmonary vascular resistance (PVR; 35% reduction vs placebo, primary endpoint), mean pulmonary arterial pressure and cardiac index vs placebo (Table). There was no significant difference between groups in change from baseline for FC or 6MWD. Most common adverse events (AEs; macitentan vs placebo) were peripheral oedema (25.6 vs 11.9%) and headache (16.3 vs 16.7%). At Week 12, mean decrease in haemoglobin was 1.8g/dL with macitentan. Four patients (macitentan) discontinued due to AEs unrelated to the liver. No patients died. One macitentan patient experienced ALT and/or AST ≥3x upper limit of normal (ULN) with total bilirubin ≥2xULN. Macitentan did not affect hepatic venous pressure gradient (n=15) or systolic blood pressure (n=40). In this first randomised controlled trial dedicated to PoPH, macitentan significantly improved PVR and other haemodynamic parameters. Safety was consistent with previous clinical trials; there were no hepatic safety concerns in this population.

Summary Background Coronary artery disease (CAD) is the leading cause of systolic heart failure (HF). Cardiac magnetic resonance imaging (CMR) is a non-invasive technique that detects a myocardial infarction scar as subendocardial or transmural late gadolinium enhancement (st-LGE). Aim We sought to evaluate whether a lack of st-LGE could rule out CAD in new-onset systolic HF of unknown aetiology. Methods We included 232 consecutive patients with new-onset HF and left ventricular ejection fraction ≤ 35% who underwent both coronary angiography and CMR to assess HF aetiology. CAD was defined as the presence of coronary artery stenosis ≥ 50% on a coronary angiogram. We assessed sensitivity, specificity, and positive and negative likelihood ratios (PLR and NLR) of the presence of st-LGE to detect underlying CAD. A complementary meta-analysis of 11 studies (including ours) was also performed. Results In our study, 49 (21.1%) patients had CAD. The sensitivity and specificity of the presence of st-LGE to detect CAD were 69 and 92%, respectively. PLR and NLR were 8.47 and 0.33, respectively. In the meta-analysis, 1227 patients were included, and the prevalence of CAD ranged from 19.2 to 68.3%. Sensitivity, specificity, PLR and NLR were 87% (95% confidence interval [CI] 0.80–0.92), 93% (95% CI 0.89–0.96), 12.91 (95% CI 7.70–21.64) and 0.14 (95% CI 0.09–0.22), respectively. Altogether, 55 patients presented CAD with no st-LGE; inversely, 75 patients presented st-LGE with no CAD. Conclusion With a CMR specificity of 93%, the absence of st-LGE rules out significant underlying CAD in patients with systolic HF of unknown aetiology in most cases.

This paper gives an overview of the accessibility features on the BNP Paribas Fortis ATM’s (Automatic Teller Machines). This document doesn’t have the intention to be scientific, but can be considered as an example how the industry is taken in account the accessibility for customers with special needs. The accessibility efforts done on our ATM’s is part of the program “An Accessible Bank For All”. The goal of this program is to provide to our customers with a disability the opportunity to carry out their banking transactions in the most autonomous and user-friendly way possible. Within this program we’ve consulted organisations, representing persons with impairments, to better understand the needs of our customers with special needs. This helped us to work out a global approach to render the use of our ATM’s as accessible as possible. We can divide the efforts on 3 levels: physical accessibility of the venue, accessibility of the hardware and accessibility features of the software.

Background: Left ventricular remodeling (LVR) after myocardial infarction is associated with an increased risk of heart failure and death. In spite of a modern therapeutic approach, LVR remains relatively frequent and difficult to predict in clinical practice. Our aim was to identify new biomarkers of LVR and understand their involvement in its development. Methods and Results: Proteomic analysis of plasma from the REVE-2 study (Remodelage Ventriculaire)—a study dedicated to the analysis of LVR which included 246 patients after a first anterior myocardial infarction—identified increased plasma levels of CLU (clusterin) in patients with high LVR. We used a rat model of myocardial infarction to analyze CLU expression in the LV and found a significant increase that was correlated with LVR parameters. We found increased CLU expression and secretion in primary cultures of rat neonate cardiomyocytes hypertrophied by isoproterenol. Silencing of CLU in hypertrophied neonate cardiomyocytes induced a significant decrease in cell size, ANP (atrial natriuretic peptide), and BNP (B-type natriuretic peptide) expression, associated with a decreased ERK (extracellular signal-regulated kinase) 1/2 activity, suggesting a prohypertrophic role of CLU. We then confirmed a significant increase of both intracellular p-CLU (precursor form of CLU) and m-CLU (mature form of CLU) in failing human hearts. Finally, the circulating levels of CLU (secreted form) were increased in patients with chronic heart failure who died from cardiovascular cause during a 3-year follow-up (n=99) compared with survivors (n=99). Conclusions: Our results show for the first time that plasma CLU levels are associated with LVR post–myocardial infarction, have in part a cardiac origin, and are a predictor of early death in heart failure patients.

Background There is an ongoing debate regarding the relevance of the 6-minute walking distance (6MWD) in systemic sclerosis (SSc) assessment, widely used as a usual test in these patients as well as an outcome measure in clinical trials. In this work, we aimed to assess the associations between the 6MWD and various disease parameters in patients with SSc. Methods Consecutive patients followed in our SSc National Reference Centre were included in this cross-sectional study if they fulfilled the 2013 American College of Rheumatology/European League Against Rheumatism criteria for SSc. Data were systematically collected during a comprehensive standardized evaluation that included a 6-minute walk test, clinical assessment, biological results, pulmonary function tests, transthoracic echocardiography, composite scores (European Scleroderma Study Group Activity Index, Medsger severity score, Health Assessment Questionnaire–Disability Index (HAQ-DI)) and treatments. Associations of the 6MWD with various disease parameters were assessed by linear regression in univariate and multivariate analyses. Results The study population comprised 298 patients (females 81%; mean age 58.2 ± 13.3 years; limited cutaneous SSc 82%; interstitial lung disease (ILD) 42%; pulmonary arterial hypertension (PAH) 6%). The 6MWD was significantly and independently associated with gender, age, body mass index, baseline heart rate (HR), HR variation during the test, PAH, history of arterial thrombosis and C-reactive protein levels, as well as with the HAQ-DI score in a sensitivity analysis. Muscle involvement, joint involvement and ILD were not independently associated with the 6MWD. Conclusions During SSc, the 6MWD is independently associated with initial HR and HR variation; with PAH but not ILD, suggesting that pulmonary vasculopathy may have a greater impact than parenchymal involvement on functional limitation; and with global markers of disease activity and patient disability. These results give clinicians further insight into how to interpret the 6MWD in the context of SSc.

Background: Current European (ERS/ESC) PH guidelines recommend risk assessment in patients with pulmonary arterial hypertension (PAH). The aim of our study were to analyze the association between the number of determinants of low-risk criteria achieved and long-term outcome. Methods: All patients with idiopathic, heritable and drug-induced PAH entered into the French Registry from 2006 and reassessed within a year were analyzed. The Cox model was used to determine the weight of 4 low-risk criteria achieved at first follow-up visit: NYHA FC, 6MWD, right atrial pressure (RAP) and cardiac index (CI). Results: 1017 patients were analyzed (mean age 57 yrs, 59% female, 75% iPAH). After a median follow-up of 34 months, 23% had died. In univariate analysis, HR (95%CI) for NYHA FC I-II, 6MWD>440 m, RAP Conclusion: These results support the relevance of ESC/ERS guidelines risk stratification to define treatment goals in patients with PAH.

Current European guidelines recommend periodic risk assessment for patients with pulmonary arterial hypertension (PAH). The aim of our study was to determine the association between the number of low-risk criteria achieved within 1 year of diagnosis and long-term prognosis. Incident patients with idiopathic, heritable and drug-induced PAH between 2006 and 2016 were analysed. The number of low-risk criteria present at diagnosis and at first re-evaluation were assessed: World Health Organization (WHO)/New York Heart Association (NYHA) functional class I or II, 6-min walking distance (6MWD) >440 m, right atrial pressure, Simplified risk assessment using the number of low-risk criteria predicts prognosis at baseline and follow-up in PAH http://ow.ly/KMsj30cPNbm

Background Right ventricular (RV) systolic function is a powerful prognostic factor in patients with systolic heart failure. The accurate estimation of RV function remains difficult. The aim of the study was to determine the diagnostic accuracy of 2D-speckle tracking RV strain in patients with systolic heart failure, analyzing both free and posterolateral walls. Methods Seventy-six patients with dilated cardiopathy (left ventricular end-diastolic volume≥75ml/m 2 ) and left ventricular ejection fraction≤45% had an analysis of the RV strain. Feasibility, reproducibility and diagnostic accuracy of RV strain were analyzed and compared to other echocardiographic parameters of RV function. RV dysfunction was defined as a RV ejection fraction≤40% measured by radionuclide angiography. Results RV strain feasibility was 93.9% for the free-wall and 79.8% for the posterolateral wall. RV strain reproducibility was good (intra-observer and inter-observer bias and limits of agreement of 0.16±1.2% [−2.2–2.5] and 0.84±2.4 [−5.5–3.8], respectively). Patients with left heart failure have a RV systolic dysfunction that can be unmasked by advanced echocardiographic imaging: mean RV strain was −21±5.7% in patients without RV dysfunction and −15.8±5.1% in patients with RV dysfunction (p=0.0001). Mean RV strain showed the highest diagnostic accuracy to predict depressed RVEF (area under the curve (AUC) 0.75) with moderate sensitivity (60.5%) but high specificity (87.5%) using a cutoff value of −16%. Conclusions RV strain seems to be a promising and more efficient measure than previous RV echocardiographic parameters for the diagnosis of RV systolic dysfunction.

SummaryThe prevalence of iron deficiency is high –even in the absence of anaemia– in patients with chronic heart failure (HF). Although iron deficiency is easily diagnosed with two biomarkers (serum ferritin and transferrin saturation), it is underdiagnosed in patients with HF. Iron is not only necessary for red blood cells, but also for cells in tissues with high-energy demands (heart, muscle, brain). Even before the onset of anaemia, HF patients with iron deficiency have decreased physical and cognitive performances and a poorer quality of life. Moreover, iron deficiency is a risk factor, independent of anaemia, of unfavourable outcome (death or heart transplantation) in patients with chronic HF. Several randomized controlled studies have shown improvement in exercise capacity, New York Heart Association functional class and quality of life after correction of iron deficiency. The results of these clinical trials, which are supported by European guidelines, suggest considering iron deficiency in HF as a possible therapeutic target.

Aims The clinical outcomes for patients with worsening chronic heart failure (WCHF) remain exceedingly poor despite contemporary evidence-based therapies, and effective therapies are urgently needed. Accumulating evidence supports augmentation of cyclic guanosine monophosphate (cGMP) signalling as a potential therapeutic strategy for HF with reduced or preserved ejection fraction (HFrEF and HFpEF, respectively). Direct soluble guanylate cyclase (sGC) stimulators target reduced cGMP generation due to insufficient sGC stimulation and represent a promising method for cGMP enhancement. Methods The phase II SOluble guanylate Cyclase stimulatoR in heArT failurE Study (SOCRATES) programme consists of two randomized, parallel-group, placebo-controlled, double-blind, multicentre studies, SOCRATES-REDUCED (in patients with LVEF

Objective To assess the association of s-blocker use with cardiovascular mortality in patients with stable coronary artery disease (CAD). Methods We analysed the data of 4184 outpatients included in a prospective cohort study on stable CAD. Two groups were formed based on s-blocker use at enrolment. Two propensity score analyses were performed to control for differences in covariates: one with adjustment among the entire cohort, and the other with propensity score matching. The outcome variable was cardiovascular mortality after a 2-year follow-up. Results There were 3320 patients with s-blocker use. Younger age, hypertension, diabetes, prior myocardial infarction, multivessel CAD, prior coronary revascularisation, prior stroke, prior hospitalisation for heart failure and a low LVEF were associated with s-blocker use. Clinical follow-up data were obtained for 4149 patients (99.2%). When adjusted on propensity score, s-blocker use was associated with a HR for cardiovascular mortality of 0.64 (0.42–0.98) in the whole cohort (p=0.04). After one-to-one propensity score matching, both groups (n=839 in each group) were well matched on covariates. The cardiovascular mortality rate in the propensity-matched cohort was significantly lower in patients with s-blocker use with a HR of 0.43 (0.22–0.82) (p=0.011). Non-cardiovascular mortality was similar in both groups. These results were consistent across different subgroups. Conclusions In this observational study of patients with stable CAD, the use of s-blockers was associated with a lower risk of cardiovascular mortality.

Background— Some patients with left ventricular systolic dysfunction (LVSD) have a dramatic improvement in left ventricular ejection fraction (LVEF) after β-blockade. No study has analyzed the long-term echocardiographic and clinical follow-up of this subgroup of patients. Methods and Results— We included in this analysis 174 consecutive patients with LVSD who had an LVEF≥45% after β-blockade. We performed a long-term echocardiographic follow-up (median 7.7 [4–9.9] years) and clinical follow-up (median 9.2 [7.2–10.8] years). LVEF improved from 33±8% to 54±6% after β-blockade ( P Conclusions— The long-term survival of patients with LVSD and with near-normal LVEF after β-blockade is good. However, a quarter of these patients may experience a subsequent degradation of LVEF. These patients are at higher risk of cardiovascular mortality.

The current use of intravenous epoprostenol in patients with severe idiopathic, heritable or anorexigen-use associated pulmonary arterial hypertension (IHA-PAH) was investigated.This observational study evaluated newly diagnosed (≤1 year) patients with IHA-PAH, enrolled in the French pulmonary hypertension (PH) registry between 2006 and 2010 and treated with epoprostenol. Among 209 consecutive patients receiving epoprostenol for the treatment of severe PH, 78 had IHA-PAH, including 43 patients naïve of previous PAH-specific treatment.After 4 months of epoprostenol therapy, improvement was observed for treatment naïve patients (n=43) and for patients who had received previous PAH-specific therapy (n=35): NYHA functional class improved in 79% and 44% of these patients, respectively, 6-minute walk distance increased by 146 (p0.0001) and 41 m (p=0.03), cardiac index increased by 1.2 (p0.0001) and 0.5 L·min(-1)·m(-2) (p=0.006), and pulmonary vascular resistance decreased by 700 (p0.0001) and 299 dyn·s·cm(-5) (p=0.009). In the treatment-naïve patient group, upfront combination of epoprostenol and oral PAH therapy tended to be more beneficial compared with epoprostenol monotherapy and was associated with improvement in cardiac index (p=0.03). The observed 1- and 3-year survival estimates from epoprostenol initiation were 84% and 69%, respectively. The highest survival rates were observed for treatment-naïve patients receiving upfront combination of epoprostenol and oral PAH therapy (92% and 88% at 1 and 3 years, respectively).First-line therapy with epoprostenol, especially when combined with oral PAH treatment, was associated with a substantial improvement in clinical and hemodynamic status and favorable survival estimates in patients with severe IHA-PAH.

Background Outcome of acute heart failure (AHF) patients according to the final destination after emergency department (ED) has been poorly studied with contradictory results. Purpose To compare long-term outcomes after an episode of acute heart failure (AHF) in patients according to their destinations after ED. Methods OFICA (Observatoire Francais de l’Insuffisance Cardiaque Aigue) is a French snapshot registry of all patients with ongoing hospitalization for AHF in a nationwide and representative sample of 170 French hospitals. One thousand six hundreds and fifty-seven patients were included the 12th of March, 2009. Various data were collected including the final destination after ED and patients were followed-up for death as primary outcome. Hazard ratios were calculated for patients admitted in geriatric departments and other wards then compared with those hospitalized in cardiology. P Results Mean age was 76,0 ± 13,2 y with a sex-ratio close to 1. Overall, the small number of AHF patients referred from the ED to a cardiology ward was 19% with more frequently HF REF. Besides, AHF patients admitted in geriatric unit were older (p Conclusion While patients have similar 1-year outcomes irrespective of the destination after ED care for an AHF episode, those initially admitted in geriatrics present worse 5-year outcomes when managed by non-cardiology departments, despite adjustment for different clinical patient profiles. Reasons for this heterogeneous specialty-related performance should be investigated.

International audience; Heart failure (HF), a major public health burden affecting 2% of industrialized populations, is a syndrome resulting from structural or functional myocardial impairment leading to inadequate cardiac output to meet the body's metabolic demands [1]. Half of HF patients present systolic dysfunction (systolic-HF), also called reduced ejection fraction (HF-REF), a disease related to various causes including idiopathic Dilated Cardiomyopathy (DCM) and Coronary Artery Diseases (CAD) (ischemic-HF). HF is usually a multifactorial disease but the genetic variants contributing to its susceptibility or its severity may be different according to its underlying causes [2] and their identification is only beginning.[...]

International audience; AIMS: To improve knowledge of epidemiological data, management, and clinical outcome of acute heart failure (AHF) in a real-life setting in France. METHODS AND RESULTS: We conducted an observational survey constituting a single-day snapshot of all unplanned hospitalizations because of AHF in 170 hospitals throughout France (the OFICA survey). A total of 1658 patients (median age 79 years, 55% male) were included. Family doctors were the first medical contact in 43% of cases, and patients were admitted through emergency departments in 64% of cases. Clinical scenarios were mainly acutely decompensated HF (48%) and acute pulmonary oedema (38%) with similar clinical and biological characteristics as well as outcome. Characteristics were different and severity higher in both shock and right HF. Infection and arrhythmia were the most frequent precipitating factors (27% and 24% of cases); diabetes and chronic pulmonary disease were the most frequent co-morbidities (31% and 21%). Over 80% of patients underwent both natriuretic peptide testing and echocardiography. LVEF was preserved (>50%) in 36% of patients and associated with specific characteristics and lower severity. Median hospital stay was 13 days; in-hospital mortality was 8.2%, and independent predictors were age, blood pressure, and creatinine. Treatment at discharge in patients with reduced LVEF included ACE inhibitors/ARBs, beta-blockers, and aldosterone inhibitors in 78, 67, and 27% cases. Non-surgical devices were reported in

International audience; Objectives Despite the wide use of the 6 min walk distance (6MWD), no study has ever assessed its validity as a surrogate marker for haemodynamics and predictor of outcome in isolated pulmonary arterial hypertension associated with systemic sclerosis (SSc-PAH). We designed this work to address this issue. Methods Treatment-naive patients with SSc-PAH were prospectively included from two sources: the French PAH Network (a prospective epidemiological cohort) (n=83) and randomised clinical trials submitted for drug approval (Food and Drug Administration) (n=332). Correlations between absolute values of the 6MWD and haemodynamics at baseline, as well as between variations of 6MWD and haemodynamics during follow-up, were studied in both populations. Results In the French cohort, baseline cardiac output (CO) (R-2=0.19, p=0.001) and New York Heart Association class (R-2=0.10, pConclusions In SSc-PAH, CO independently correlates with 6MWD at baseline, but accounts for a small amount of the variance of 6MWD in both study samples. This suggests that other non-haemodynamic factors could have an impact on the walk distance. Moreover, variations of 6MWD do not reflect changes in haemodynamics among treated patients. Our results suggest that 6MWD is not an accurate surrogate marker for haemodynamic severity, nor an appropriate outcome measure to assess changes in haemodynamics during follow-up in treated SSc-PAH.

In this paper the Working Group on Myocardial and Pericardial Disease proposes a revised definition of dilated cardiomyopathy (DCM) in an attempt to bridge the gap between our recent understanding of the disease spectrum and its clinical presentation in relatives, which is key for early diagnosis and the institution of potential preventative measures. We also provide practical hints to identify subsets of the DCM syndrome where aetiology directed management has great clinical relevance.

BACKGROUND: Aging populations show higher incidences of myocardial infarction (MI) and heart failure (HF). Cardiac remodeling post-MI leads to progressive impaired cardiac function caused by a disarray of several processes including derailed autophagy. Microribonucleic acids (miRNAs) are known to be key players in cardiovascular disease but their involvement in cardiac autophagy and aging is not well understood.OBJECTIVES: This study sought to identify new miRNA candidates that regulate cardiac autophagy and aging.METHODS: We exploited a high-throughput, fluorescence-activated cell sorting-based green fluorescent protein-LC3 detection method to measure the autophagic flux in cardiomyocytes after transfection of a precursor miRNA library consisting of 380 miRNAs. This was followed by a series of molecular and in vivo studies.RESULTS: Together with additional expression screenings, we identified miR-22 as an abundant and strong inhibitor of the cardiac autophagy process. Cardiac miR-22 expression levels increased during aging of mice as well as in aging neonatal cardiomyocytes in vitro by a P53-dependent mechanism. Inhibition of miR-22 in aging cardiomyocytes in vitro activated autophagy and inhibited cellular hypertrophy. Pharmacological inhibition of miR-22 post-MI in older mice activated cardiac autophagy, prevented post-infarction remodeling, and improved cardiac function compared with control subjects. Interestingly, similar effects were less pronounced in younger mice with significantly lower cardiac miR-22 expression levels. In addition, circulating levels of miR-22 in 154 patients with systolic HF were highly associated with early mortality.CONCLUSIONS: We concluded that miR-22 is an important regulator of cardiac autophagy and a potential therapeutic target, especially in the older myocardium. Finally, circulating miR-22 provides prognostic information for HF patients, highlighting miR-22 as a promising therapeutic and biomarker candidate for cardiovascular disorders.

It is not well known whether the gap in outcomes after myocardial infarction (MI) between patients with and without diabetes mellitus (DM) has changed over time. We performed a systematic review and metaregression of temporal trends in the excess mortality associated with DM after MI.We searched the PubMed database for studies reporting mortality data according to diabetic status in patients hospitalized for MI or acute coronary syndromes (ACS). We included 139 studies/cohorts for analysis (432,066 diabetic patients and 1,182,108 nondiabetic patients).When compared to their non-diabetic counterparts, patients with DM had an odds ratio (OR) [95% CI] of 1.66 [1.59-1.74] (P0.0001) for early mortality, and of 1.86 [1.75-1.97] (P0.0001) for 6-12months mortality. When all data from the 116 studies reporting early mortality were pooled, there was no significant relationship between calendar year and Log (OR). Likewise, when considering the 61 studies reporting 6-12months mortality, there was no significant relationship between calendar year and Log (OR). Similar to the overall pooled analysis, no significant relationship between inclusion year and Log (OR) for mortality in diabetic patients was observed in sensitivity analyses performed in studies with ST-elevation MI as inclusion criteria, in randomized trials, in studies including2000 patients, and in studies with DM prevalence20%.We found no evidence for temporal changes in the incremental mortality risk associated with DM in the setting of MI. The improvements in management of MI patients during the last decades have not been associated with a reduction of the gap between diabetic and non-diabetic patients.

Treatment for pulmonary arterial hypertension (PAH) has been underpinned by single-agent therapy to which concomitant drugs are added sequentially when pre-defined treatment goals are not met.This retrospective analysis of real-world clinical data in 97 patients with newly diagnosed PAH (86% in New York Heart Association functional class III−IV) explored initial dual oral combination treatment with bosentan plus sildenafil (n=61), bosentan plus tadalafil (n=17), ambrisentan plus tadalafil (n=11) or ambrisentan plus sildenafil (n=8).All regimens were associated with significant improvements in functional class, exercise capacity, dyspnoea and haemodynamic indices after 4 months of therapy. Over a median follow-up period of 30 months, 75 (82%) patients were still alive, 53 (71%) of whom received only dual oral combination therapy. Overall survival rates were 97%, 94% and 83% at 1, 2 and 3 years, respectively, and 96%, 94% and 84%, respectively, for the patients with idiopathic PAH, heritable PAH and anorexigen-induced PAH. Expected survival rates calculated from the French equation for the latter were 86%, 75% and 66% at 1, 2 and 3 years, respectively.Initial combination of oral PAH-targeted medications may offer clinical benefits, especially in PAH patients with severe haemodynamic impairment.

Aim Peripartum cardiomyopathy (PPCM) is a rare cause of dilated cardiomyopathy responsible for heart failure toward the end of pregnancy, which can lead to chronic heart failure in 50% of cases. In this short report, we assessed the benefit of cardiac resynchronization in patients with PPCM and chronic systolic dysfunction despite optimal medical treatment. Methods and results For the last 10 years, we managed eight patients diagnosed with PPCM. Two of them presented severe systolic dysfunction, and medical treatment resulted in limited improvement from 10% to 25% and from 25% to 28% despite optimal treatment for 9 and 6 years, respectively. These two patients were porposed to receive an implantatable cardioverter defibrillator (ICD) and cardiac resynchronization therapy (CRT). Six months after ICD-CRT treatment, we observed a significant improvement in systolic function from 25% to 45% and 28% to 50%, respectively, and positive remodelling with reduction of left ventricular end-diastolic volume from 216 to 144 mL and from 354 to 105 mL, which represent a 34% and a 70% reduction, respectively. Conclusions Physicians in charge of patients with PPCM should offer the opportunity of CRT for patients whose cardiac function has not significantly improved under standard medical treatment.

Summary Background Limited recent data are available in the literature on whether the presence of left ventricular systolic dysfunction (LVSD) affects the therapeutic management of patients with stable coronary artery disease (CAD). Aims The objectives of this study were to analyse prevalence, effect on therapeutics and prognosis of LVSD in stable CAD. Methods We prospectively included 4184 CAD outpatients free from any myocardial infarction or coronary revascularization for > 1 year. Left ventricular ejection fraction (EF) was available for 4124 (98.6%) patients. Follow-up was performed at 2 years. All events were adjudicated blindly. Results The mean EF was 57.5 ± 10.8%, and 201 (4.9%) patients had an EF ≤ 35%. The prescription of renin–angiotensin system inhibitors and beta-blockers was inversely related to EF, and reached > 90% in patients with EF ≤ 35%. Seventy-five (37.3%) of the patients with EF ≤ 35% received a mineralocorticoid receptor antagonist. Eighty-five (42.3%) of the patients with EF ≤ 35% had an implantable cardioverter defibrillator. Clinical follow-up data were obtained for 4090 patients (99.2%). Event rates were higher in patients with low EF (adjusted hazard ratio [95% confidence interval] for EF ≤ 35%, with EF ≥ 60% as reference: 3.93 [2.60–5.93] and 7.12 [3.85–13.18], for all-cause death and cardiovascular death, respectively). Conclusions In patients with stable CAD, LVSD is well taken into account by cardiologists, with extensive use of evidence-based medications and interventions. Despite this, LVSD remains a major prognostic indicator in this population.

The prognostic importance of follow-up haemodynamics and the validity of multidimensional risk assessment are not well established for systemic sclerosis (SSc)-associated pulmonary arterial hypertension (PAH).We assessed incident SSc-PAH patients to determine the association between clinical and haemodynamic variables at baseline and first follow-up right heart catheterisation (RHC) with transplant-free survival. RHC variables included cardiac index, stroke volume index (SVI), pulmonary arterial compliance and pulmonary vascular resistance. Risk assessment was performed according to the number of low-risk criteria: functional class I or II, 6-min walking distance (6MWD) >440 m, right atrial pressure −1·m−2.Transplant-free survival from diagnosis (n=513) was 87%, 55% and 35% at 1, 3 and 5 years, respectively. At baseline, 6MWD was the only independent predictor. A follow-up RHC was available for 353 patients (median interval 4.6 months, interquartile range 3.9–6.4 months). The 6MWD, functional class, cardiac index, SVI, pulmonary arterial compliance and pulmonary vascular resistance were independently associated with transplant-free survival at follow-up, with SVI performing better than other haemodynamic variables. 1-year outcomes were better with increasing number of low-risk criteria at baseline (area under the curve (AUC) 0.63, 95% CI 0.56–0.69) and at first follow-up (AUC 0.71, 95% CI 0.64–0.78).Follow-up haemodynamics and multidimensional risk assessment had greater prognostic significance than at baseline in SSc-PAH.
