RESUMEN
BACKGROUND: European Society of Cardiology (ESC) guidelines recommend measuring natriuretic peptides (BNP or NT-proBNP) in patients with suspected heart failure (HF) as a first-line tool. HF should be ruled-out if concen-trations of NT-proBNP are below 300 ng/L and 125 ng/L for acute HF and chronic HF, respectively. METHODS: Patients with suspected HF referred for transthoracic echocardiography (TTE) were enrolled; NT-pro-BNP concentrations were obtained from medical charts (measurement < 48 hours) or prospectively measured on the day of TTE. RESULTS: Out of 109 patients, NT-proBNP was measured by the referring department before TTE in 40 patients (36.7%), and 37.5% of these patients had NT-proBNP concentration below the rule-out threshold. NT-proBNP was measured in additional 38 patients on the day of TTE. Overall, 38.5% of the patients had a NT-proBNP concentration below the threshold value. CONCLUSIONS: Natriuretic peptides are not routinely measured in patients with suspected HF; systematic measurement would reduce unnecessary TTE by at least 38.5%.

AIMS: Although several studies have shown that the right ventricular to pulmonary artery (RV-PA) coupling, assessed by the ratio between tricuspid annular plane systolic excursion and systolic pulmonary artery pressure (TAPSE/sPAP) using echocardiography, is strongly associated with cardiovascular events, its prognostic value is not established in acute coronary syndrome (ACS). We aimed to assess the in-hospital prognostic value of TAPSE/sPAP among patients hospitalized for ACS in a retrospective analysis from the prospective ADDICT-ICCU study. METHODS AND RESULTS: 481 consecutive patients hospitalized in intensive cardiac care unit (mean age 65±13 years, 73% of male, 46% STEMI) for ACS (either ST-elevation [STEMI] or non-ST-elevation [NSTEMI] myocardial infarction) with TAPSE/sPAP available were included in this prospective French multicentric study (39 centers). The primary outcome was in-hospital major adverse cardiovascular events (MACEs) defined as all-cause death, resuscitated cardiac arrest or cardiogenic shock and occurred in 33 (7%) patients. ROC-curve analysis identified 0.55 mm/mmHg as the best TAPSE/sPAP cut-off to predict in-hospital MACEs. TAPSE/sPAP <0.55 was associated with in-hospital MACEs, even after adjustment with comorbidities (OR:19.1, 95%CI[7.78-54.8]), clinical severity including left ventricular ejection fraction (OR:14.4, 95%CI[5.70-41.7]) and propensity-matched population analysis (OR:22.8, 95%CI[7.83-97.2], all p<0.001). After adjustment, TAPSE/sPAP <0.55 showed the best improvement in model discrimination and reclassification above traditional prognosticators (C-statistic improvement: 0.16; global chi-square improvement: 52.8; LR-test p<0.001) with similar results for both STEMI and NSTEMI subgroups. CONCLUSION: A low RV-PA coupling defined as TAPSE/sPAP ratio <0.55 was independently associated with in-hospital MACEs and provided incremental prognostic value over traditional prognosticators in patients hospitalized for ACS. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05063097.
RESUMEN
AIMS: Tricuspid annular plane systolic excursion over systolic pulmonary artery pressure (TAPSE/sPAP) assessed by echocardiography appears to be a good non-invasive approach for right ventricular to pulmonary artery coupling assessment. We aimed to assess the in-hospital prognostic value of TAPSE/sPAP among patients hospitalized for acute heart failure (AHF). METHODS AND RESULTS: In total, 333 consecutive patients (mean age 68 ± 14 years, 70% of male, mean left ventricular ejection fraction 44 ± 16%) were hospitalized for AHF across 39 French cardiology departments, with TAPSE/sPAP measured by echocardiography within the first 24â h of hospitalization were included in this prospective study. The primary outcome was in-hospital major adverse cardiovascular events (MACEs) defined as all-cause death, resuscitated cardiac arrest or cardiogenic shock and occurred in 50 (15%) patients. Using receiver operating characteristic curve analysis, the best TAPSE/sPAP threshold for in-hospital MACEs was 0.40â mm/mmHg. TAPSE/sPAP < 0.40â mm/mmHg was independently associated with in-hospital MACEs, even after adjustment with comorbidities [odds ratio (OR): 3.75, 95% CI (1.87-7.93), P < 0.001], clinical severity [OR: 2.80, 95% CI (1.36-5.95), P = 0.006]. Using a 1:1 propensity-matched population, TAPSE/sPAP ratio < 0.40 was associated with a higher rate of in-hospital MACEs [OR: 2.98, 95% CI (1.53-6.12), P = 0.002]. After adjustment, TAPSE/sPAP < 0.40 showed the best improvement in model discrimination and reclassification above traditional prognostic factors (C-statistic improvement: 0.05; χ2 improvement: 14.4; likelihood-ratio test P < 0.001). These results were consistent in an external validation cohort of 133 patients. CONCLUSION: TAPSE/sPAP < 0.40â mm/mmHg assessed by an early echocardiography during an AHF episode is independently associated with in-hospital MACEs suggesting enhanced close monitoring and strengthened heart failure-specific care in these patients. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05063097.

NATRIURETIC PEPTIDES IN THE DIAGNOSIS AND MONITORING OF CARDIAC FAILURE. Heart failure (HF) is a serious and common disease requiring a prompt diagnosis for appropriate management. Natriuretic peptides, such as BNP and NT-proBNP, play a crucial role in diagnosing HF due to their s pecificity and reproducibility. It is important to measuring natriuretic peptides, especially in cases of acute dyspnea, to differentiate cardiac causes from others. Specific thresholds are recommended, with high values strongly suggest HF, while normal levels rule out the diagnosis. Clinical characteristics, such as age, renal function, atrial fibrillation, obesity, and gender, influence natriuretic peptides levels and should be considered in interpretation. For diabetic, hypertensive, and obese patients, early screening for HF through natriuretic peptides measurement is crucial. Furthermore, these natriuretic peptides are useful for monitoring chronic heart failure patients. They assist in confirming decompensation, titrating treatment, evaluating treatment response, and establishing prognosis. However, it's essential to choose a single biomarker (BNP or NT-proBNP) to avoid confusion.
DANS LE DIAGNOSTIC ET LE SUIVI DE L'INSUFFISANCE CARDIAQUE. L'insuffisance cardiaque (IC) est une maladie grave et fréquente nécessitant un diagnostic rapide pour une prise en charge adéquate. Les peptides natriurétiques, tels que le BNP et le NT-proBNP, jouent un rôle essentiel dans le diagnostic de l'IC en raison de leur spécificité et de leur reproductibilité. Il est important de doser les peptides natriurétiques, en particulier lors d'une dyspnée aiguë, pour différencier les causes cardiaques des autres. Des seuils spécifiques sont recommandés, et des valeurs élevées évoquent fortement une IC, tandis que des taux normaux écartent le diagnostic. Les caractéristiques cliniques telles que l'âge, la fonction rénale, la fibrillation atriale, l'obésité et le sexe modifient les taux de peptides natriurétiques et doivent être prises en compte dans l'interprétation. Chez les patients diabétiques, hypertendus et obèses, le dépistage précoce de l'IC par le dosage des peptides natriurétiques est crucial. De plus, ces peptides natriurétiques sont utiles pour le suivi des patients insuffisants cardiaques chroniques. Ils aident à confirmer une décompensation, à titrer le traitement, à en évaluer la réponse et à établir un pronostic. Cependant, il est essentiel de choisir un seul biomarqueur (BNP ou NT-proBNP) pour éviter toute confusion.

OBJECTIVE: Describe the characteristics of patients presenting with TTS during the course of a broad spectrum of systemic diseases, in comparison to classic TTS. METHODS: French multicenter retrospective case-control study completed by a literature review. RESULTS: 19 new cases were included in the study. The literature review identified 25 previously published cases. Among the 44 patients, 41 were females, with a median age of 67 years. The main underlying systemic diseases were systemic lupus erythematosus for seven, rheumatoid arthritis for six and primary Sjögren's syndrome for five. A TTS trigger was found in 34 cases, including a systemic disease flare-up in 28. The flare-up was treated in 15 cases, mainly with corticosteroids. One patient died during the episode, unrelated to the TTS. With a median follow-up of 24 months, all patients had recovered a normal LVEF, one had presented a recurrence of TTS, and none had died of a cardiac cause. Finally, the 19 new patients were compared with 19 classic TTS. The disease characteristics were extremely similar, with no significant difference in terms of clinical, electrocardiographic, biological and echocardiographic presentation. CONCLUSION: A broad spectrum of systemic diseases may rarely be accompanied by TTS, particularly during disease flare-ups. Although uncommon, TTS should be borne in mind in the presence of any cardiac symptomatology during the course of a systemic disease. Compared with classic TTS, their clinical, biological and echographic presentation is unremarkable. The prognosis for TTS appears to be good, with the consistent recovery of LVEF and no cardiac-related deaths.
RESUMEN
El tratamiento de los pacientes con insuficiencia cardiaca con fracción de eyección reducida (IC-FEr) con una combinación de 4 clases de fármacos se recomienda en las principales guías de práctica clínica internacionales. Sin embargo, no especifican cómo deben introducirse y ajustarse estos tratamientos. En consecuencia, muchos pacientes con IC-FEr no pasan a un régimen de tratamiento optimizado. El objetivo de esta revisión es proponer un algoritmo pragmático para optimizar el tratamiento, diseñado para que sea lo más fácil posible de aplicar en la práctica diaria. El primer objetivo es garantizar que las 4 clases de medicación recomendadas se inicien cuanto antes para establecer una terapia eficaz, incluso a dosis bajas. Esto se considera preferible a iniciar menos medicamentos a una dosis máxima. El segundo objetivo es garantizar que los intervalos entre la introducción de los medicamentos y entre los distintos pasos de titulación sean lo más breves posible, por la seguridad del paciente. Se hacen propuestas específicas para los pacientes de edad avanzada (> 75 años) frágiles, y para aquellos con trastornos del ritmo cardiaco. La aplicación de este algoritmo debería permitir alcanzar un protocolo de tratamiento óptimo en un plazo de 2 meses para la mayoría de los pacientes. Este debe ser nuestro objetivo en el tratamiento de la IC-FEr. (AU)
Major international practice guidelines recommend the use of a combination of 4 medication classes in the treatment of patients with heart failure with reduced ejection fraction (HFrEF) but do not specify how these treatments should be introduced and up-titrated. Consequently, many patients with HFrEF do not receive an optimized treatment regimen. This review proposes a pragmatic algorithm for treatment optimization designed to be easily applied in routine practice. The first goal is to ensure that all 4 recommended medication classes are initiated as early as possible to establish effective therapy, even at a low dose. This is considered preferable to starting fewer medications at a maximum dose. The second goal is to ensure that the intervals between the introduction of different medications and between different titration steps are as short as possible to ensure patient safety. Specific proposals are made for older patients (> 75 years) who are frail, and for those with cardiac rhythm disorders. Application of this algorithm should allow an optimal treatment protocol to be achieved within 2-months in most patients, which should the treatment goal in HFrEF. (AU)

WHAT IS KNOWN AND OBJECTIVE: This study aimed to determine the results of INR monitoring in patients on vitamin K antagonists (VKAs) and the time in therapeutic range (TTR) in 'real-world' settings. METHODS: Retrospective analysis of 836,857 INR measurements performed in adults from February 2010 to August 2015 in two districts in the French Brittany region. RESULTS: Of the 836,857 INR measurements, 94.9% were ordered by general practitioners and 2.0% by cardiologists. The number of tests increased by 10-year age categories up to the age-group of 80-90 years. The number of INR measurements increased from 169,636 in 2011 to 176,184 in 2012, but then decreased slightly to 162,597 in 2013 and 164,427 in 2014. Mean coefficient of variation of INR was 19.0%, and mean TTR was 29.0%. TTR was higher in women than in men (31% vs. 18%), in older than in younger patients (19.1% at 40 years and 38.6% at 100 years) and in patients with arrhythmias than in those with deep vein thrombosis/pulmonary embolism (44.4% versus 19.4%) (p < 10-5 for each comparison). Median interval between INR measurements was 14 days [7-28]; it was prolonged in men vs women, rural vs urban regions, older vs younger patients and when requested by GPs vs cardiologists. The interval was shorter for patients with INR outside the therapeutic range versus patients with INR within the therapeutic range (9 days [5-21] vs. 18 days [10-29], p < 10-10 ). WHAT IS NEW AND CONCLUSION: VKAs are still frequently prescribed in this era of direct oral anticoagulants. The low TTR cannot be explained by inadequate INR monitoring.

Introduction: Despite widespread investigation into the incidence of acute myocardial infarction during the coronavirus disease 2019 (COVID-19) pandemic and associated lockdown, no study has examined the situation's impact on blood pressure (BP) levels. Methods: Measurements of BP and heart rate (HR) were obtained from persons living in the Paris urban area using connected home BP monitors (accessible to patients and health providers through a secured server). Three time periods of e-health recordings were compared: during the pandemic before the lockdown, during the lockdown, and the same time period in 2019. Results: A total of 297,089 BP recordings from 2,273 participants (age 56.3 ± 12.8 years, 81.1% male) were made. During confinement, systolic BP gradually decreased by 3 mmHg (-2.4 to -3.9), and diastolic BP by 1.5 mmHg (-1.4 to -2.2) (all p < 0.001); this decrease was greater for participants with higher BP (p < 0.0001 each). No significant variation in HR was noted. Conclusion: Among a very large cohort, we observed a significant decrease in home BP measured with e-health devices during the first lockdown period. This study emphasizes the research potential of e-health during the COVID-19 crisis.

Systemic sclerosis (SSc) is a generalized disease of the connective tissue, arterioles, and microvessels, characterized by the appearance of fibrosis and vascular obliteration. There are two main phenotypical forms of SSc: a diffuse cutaneous form that extends towards the proximal region of the limbs and/or torso, and a limited cutaneous form where the cutaneous sclerosis only affects the extremities of the limbs (without passing beyond the elbows and knees). There also exists in less than 10% of cases forms that never involve the skin. This is called SSc sine scleroderma. The prognosis depends essentially on the occurrence of visceral damage and more particularly interstitial lung disease (which is sometimes severe), pulmonary arterial hypertension, or primary cardiac damage, which represent the three commonest causes of mortality in SSc. Another type of involvement with poor prognosis, scleroderma renal crisis, is rare (less than 5% of cases). Cutaneous extension is also an important parameter, with the diffuse cutaneous forms having less favorable prognosis.

BACKGROUND: "Sarcoidosis-like" paradoxical reactions to Antitumor necrosis factor α (anti-TNFα) treatment have been reported. The clinical presentations are varied, most of the time, with a relatively typical picture of mediastinopulmonary involvement. More rarely, isolated granulomatous locations from various organs are described, leading to difficulties in diagnosis. CASE PRESENTATION: We report a granulomatous cardiac valve location complicating etanercept treatment in a 26-years-old caucasian male with rheumatoid arthritis. The patient received leflunomide and low-dose corticosteroids, then etanercept was introduced because of persistent disease activity. He had no history of tuberculosis infection or contact, chest CT-scan was normal. At 3 months, he showed complete remission. After 6 months of etanercept treatment, the patient suddenly complained of headache with scotomas of the right visual field and vertigo, without fever. Cerebral MRI revealed 3 recent infarcts. Cardiac ultrasonography revealed a mobile mass on the posterior mitral leaflet. C-reactive protein level was 8mg/L, and all analyses were negative for an infectious agent. Leflunomide and etanercept were discontinued, and antibiotic therapy was started. Mitral valve resection and plasty were performed 2 days later. Histology of the valve revealed large non-caseating epithelioid granulomas with a suppurative-like necrotic center. After ruling out infectious endocarditis, sarcoidosis, rheumatoid valvulitis or lupus-like reaction induced by anti-TNF therapy, the diagnosis of a paradoxical reaction to etanercept was finally retained. Tocilizumab monotherapy was introduced to treat RA flare, no antibiotic preventive treatment was added. After 2 years, the patient was in remission. CONCLUSION: This case raises for the first time the possibility of a paradoxical adverse event with an isolated granulomatous reaction on the heart valve occurring with anti-TNF treatment, namely etanercept.

AIMS: To estimate the effect of prophylactic angiotensin-converting enzyme inhibitors (ACEi) on survival in Duchenne muscular dystrophy (DMD). METHODS AND RESULTS: We analysed the data from the French multicentre DMD Heart Registry (ClinicalTrials.gov: NCT03443115). We estimated the association between the prophylactic prescription of ACEi and event-free survival in 668 patients aged 8 to 13 years, with normal left ventricular function, using (i) a Cox model with intervention as a time-dependent covariate, (ii) a propensity-based analysis comparing ACEi treatment vs. no treatment, and (iii) a set of sensitivity analyses. The study outcomes were overall survival and hospitalizations for heart failure (HF) or acute respiratory failure. Among the 668 patients included in the DMD Heart Registry, 576 (mean age 6.1 ± 2.8 years) were eligible for this study, of whom 390 were treated with ACEi prophylactically. Death occurred in 53 patients (13.5%) who were and 60 patients (32.3%) who were not treated prophylactically with ACEi, respectively. In a Cox model with intervention as a time-dependent variable, the hazard ratio (HR) associated with ACEi treatment was 0.49 [95% confidence interval (CI) 0.34-0.72] and 0.47 (95% CI 0.31-0.17) for overall mortality after adjustment for baseline variables. In the propensity-based analysis, 278 patients were included in the treatment group and 834 in the control group, with 18.5% and 30.4% 12-year estimated probability of death, respectively. ACEi were associated with a lower risk of death (HR 0.39; 95% CI 0.17-0.92) and hospitalization for HF (HR 0.16; 95% CI 0.04-0.62). All other sensitivity analyses yielded similar results. CONCLUSION: Prophylactic ACEi treatment in DMD was associated with a significantly higher overall survival and lower rates of hospitalization for HF.

BACKGROUND: An accurate estimation of the duration of atrial fibrillation is critical for its safe management. Recent studies suggested that copeptin, carbohydrate antigen-125, galectin-3 and growth differentiation factor-15 are increased in atrial fibrillation. We examined the ability of these markers to identify patients presenting with atrial fibrillation of ≤48 versus >48 h duration. METHODS: Retrospective analysis of a prospective study that included patients with atrial fibrillation of known duration. RESULTS: A total of 98 patients were analysed, 47 with atrial fibrillation ≤48 h and 51 with >48 h. In patients presenting with atrial fibrillation of ≤48 versus >48 h duration, the mean carbohydrate antigen-125 concentration was 16.9 ± 12.5 versus 30.9 ± 36.3 U/mL (P = 0.01), and growth differentiation factor-15 concentration was 1320 ± 889 versus 2608 ±2163 pg/mL (P < 0.001). Copeptin concentration was not independently associated with atrial fibrillation duration. The galectin-3 concentration did not differ between groups. Area under the ROC curve to identify patients with atrial fibrillation ≤48 h was 0.869 for carbohydrate antigen-125, 0.853 for growth differentiation factor-15. CONCLUSION: The plasma concentrations of carbohydrate antigen-125, growth differentiation factor-15 and copeptin, but not galectin-3, are higher in patients presenting with atrial fibrillation of >48 h duration than in those with atrial fibrillation ≤48 h. The ability to discriminate recent atrial fibrillation offered by carbohydrate antigen-125 and growth differentiation factor-15 seems high.

OBJECTIVES: Copeptin and high-sensitivity cardiac troponin (HS-cTn) assays improve the early detection of non-ST-segment elevation myocardial infarction (NSTEMI). Their sensitivities may, however, be reduced in very early presenters. SETTING: We performed a post hoc analysis of three prospective studies that included patients who presented to the emergency department for chest pain onset (CPO) of less than 6 hours. PARTICIPANTS: 449 patients were included, in whom 12% had NSTEMI. CPO occurred <2 hours from ED presentation in 160, between 2 and 4 hours in 143 and >4 hours in 146 patients. The prevalence of NSTEMI was similar in all groups (9%, 13% and 12%, respectively, p=0.281). MEASURES: Diagnostic performances of HS-cTn and copeptin at presentation were examined according to CPO. The discharge diagnosis was adjudicated by two experts, including cardiac troponin I (cTnI). HS-cTn and copeptin were blindly measured. RESULTS: Diagnostic accuracies of cTnI, cTnI +copeptin and HS-cardiac troponin T (HS-cTnT) (but not HS-cTnT +copeptin) lower through CPO categories. For patients with CPO <2 hours, the choice of a threshold value of 14 ng/L for HS-cTnT resulted in three false negative (Sensitivity 80%(95% CI 51% to 95%); specificity 85% (95% CI 78% to 90%); 79% of correctly ruled out patients) and that of 5 ng/L in two false negative (sensitivity 87% (95% CI 59% to 98%); specificity 58% (95% CI 50% to 66%); 52% of correctly ruled out patients). The addition of copeptin to HS-cTnT induced a decrease of misclassified patients to 1 in patients with CPO <2 hours (sensitivity 93% (95% CI 66% to 100%); specificity 41% (95% CI 33% to 50%)). CONCLUSION: A single measurement of HS-cTn, alone or in combination with copeptin at admission, seems not safe enough for ruling out NSTEMI in very early presenters (with CPO <2 hours). TRIAL REGISTRATION NUMBER: DC-2009-1052.

PURPOSE: The diagnostic and prognostic significance of procalcitonin remains uncertain in HF patients. We reviewed and performed a meta-analysis of studies that measured PCT in HF patients, with or without infection. MATERIALS AND METHODS: We identified seven studies (9514 patients, 5810 with diagnoses of HF) eligible for our analysis, out of 247 examined. We estimated the serum PCT concentrations in patients with and without HF and/or infection and examined the mortality rates of patients with versus without elevated serum PCT concentrations. RESULTS: The mean age of the study samples ranged between 58 and 81 years, the men proportion between 47% and 66%, the follow-up duration between 22 and 180 days. The median PCT concentration in patients with HF and concomitant infections tended to be higher (0.26 ng/l [0.06, 0.46]) than in patients with HF alone (0.10 ng/l [0.08, 0.12]; p = 0.059). The mortality of patients suffering from HF and whose serum PCT concentrations were elevated was significantly higher than that of patients suffering from HF whose PCT concentrations were normal at 30 (2.66 [1.74, 4.05]), 90 (2.12 [1.59, 2.83]) and 180 days (2.06 [1.13, 3.78]). CONCLUSIONS: In patients with HF, an elevated serum PCT concentration predicted the short-term risk of death.

The new paradigm of the big data raises many expectations, particularly in the field of health. Curiously, even though medical biology laboratories generate a great amount of data, the opportunities offered by this new field are poorly documented. For better understanding the clinical context of chronical disease follow-up, for leveraging preventive and/or personalized medicine, the contribution of big data analytics seems very promising. It is within this framework that we have explored to use data of a Breton group of laboratories of medical biology to analyze the possible contributions of their exploitation in the improvement of the clinical practices and to anticipate the evolution of pathologies for the benefit of patients. We report here three practical applications derived from routine laboratory data from a period of 5 years (February 2010-August 2015): follow-up of patients treated with AVK according to the recommendations of the High authority of health (HAS), use of the new troponin markers HS and NT-proBNP in cardiology. While the risks and difficulties of using algorithms in the health domain should not be underestimated - quality, accessibility, and protection of personal data in particular - these first results show that use of tools and technologies of the big data repository could provide decisive support for the concept of "evidence based medicine".

Cardiac involvement contributes to the severity of SSc and should carefully be investigated and managed in SSc patients. Although it is commonly sub-clinical, once symptomatic it has a poor prognosis. Several complementary tools (circulating biomarkers, electrocardiography, echocardiography, scintigraphy or MRI) allow the assessment of all the various cardiac structures (endocardium, myocardium and pericardium) and heart function. Treatment remains empirical but cardiac trials in SSc can add data to the treatment of this complication.

OBJECTIVES: To determine the causes of death and risk factors in systemic sclerosis (SSc). METHODS: Between 2000 and 2011, we examined the death certificates of all French patients with SSc to determine causes of death. Then we examined causes of death and developed a score associated with all-cause mortality from the international European Scleroderma Trials and Research (EUSTAR) database. Candidate prognostic factors were tested by Cox proportional hazards regression model by single variable analysis, followed by a multiple variable model stratified by centres. The bootstrapping technique was used for internal validation. RESULTS: We identified 2719 French certificates of deaths related to SSc, mainly from cardiac (31%) and respiratory (18%) causes, and an increase in SSc-specific mortality over time. Over a median follow-up of 2.3 years, 1072 (9.6%) of 11 193 patients from the EUSTAR sample died, from cardiac disease in 27% and respiratory causes in 17%. By multiple variable analysis, a risk score was developed, which accurately predicted the 3-year mortality, with an area under the curve of 0.82. The 3-year survival of patients in the upper quartile was 53%, in contrast with 98% in the first quartile. CONCLUSION: Combining two complementary and detailed databases enabled the collection of an unprecedented 3700 deaths, revealing the major contribution of the cardiopulmonary system to SSc mortality. We also developed a robust score to risk-stratify these patients and estimate their 3-year survival. With the emergence of new therapies, these important observations should help caregivers plan and refine the monitoring and management to prolong these patients' survival.
