Measurement of Natriuretic Peptides in Patients with Suspected Heart Failure to Prevent Overuse of Echocardiography - a Pilot Study.

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%.

Real-life contemporary vitamin K antagonist is still associated with very low time in therapeutic range despite strict international normalized ratio monitoring: Results of big data analysis.

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.

Association between prophylactic angiotensin-converting enzyme inhibitors and overall survival in Duchenne muscular dystrophy-analysis of registry data.

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.

Evidence of a Blood Pressure Reduction During the COVID-19 Pandemic and Associated Lockdown Period: Insights from e-Health Data.

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.

Prognostic and diagnostic value of elevated serum concentration of procalcitonin in patients with suspected heart failure. A review and meta-analysis.

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.

Mapping and predicting mortality from systemic sclerosis.

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.

Points to consider when doing a trial primarily involving the heart.

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.

Atrial fibrillation in CLL patients treated with ibrutinib. An international retrospective study.

Atrial fibrillation (AF) occurs in 5-9% of patients treated with ibrutinib for chronic lymphocytic leukaemia (CLL); the clinical consequences and optimal management are unclear. We retrospectively studied 56 CLL patients who received ibrutinib and developed AF. Median time to onset was 3·8 months. AF was persistent in 35/56 (62%) cases despite treatment. Clinical consequences included: three episodes of severe cardiac failure (one fatal) and one stroke; eight non-thrombocytopenic patients (14%) experienced severe bleeding adverse events. Altogether, ibrutinib was permanently discontinued in 26/56 cases (46%). Data to guide optimal management are lacking and clinical practice guidelines are urgently needed.

Comparison of conventional and high-sensitivity troponin in patients with chest pain: a collaborative meta-analysis.

BACKGROUND: Multiple studies have evaluated the diagnostic and prognostic performance of conventional troponin (cTn) and high-sensitivity troponin (hs-cTn). We performed a collaborative meta-analysis comparing cTn and hs-cTn for diagnosis of acute myocardial infarction (AMI) and assessment of prognosis in patients with chest pain. METHODS: MEDLINE/PubMed, Cochrane CENTRAL, and EMBASE were searched for studies assessing both cTn and hs-cTn in patients with chest pain. Study authors were contacted and many provided previously unpublished data. RESULTS: From 17 included studies, there were 8,644 patients. Compared with baseline cTn, baseline hs-cTn had significantly greater sensitivity (0.884 vs 0.749, P < .001) and negative predictive value (NPV; 0.964 vs 0.935, P < .001), whereas specificity (0.816 vs 0.938, P < .001) and positive predictive value (0.558 vs 0.759, P < .001) were significantly reduced. Based on summary receiver operating characteristic curves, test performance for the diagnosis of AMI was not significantly different between baseline cTn and hs-cTn (0.90 [95% CI 0.85-0.95] vs 0.92 [95% CI 0.90-0.94]). In a subanalysis of 6 studies that alternatively defined AMI based on hs-cTn, cTn had lower sensitivity (0.666, P < .001) and NPV (0.906, P < .001). Elevation of baseline hs-cTn, but negative baseline cTn, was associated with increased risk of death or nonfatal myocardial infarction during follow-up (P < .001) compared with both negative. CONCLUSION: High-sensitivity troponin has significantly greater early sensitivity and NPV for the diagnosis of AMI at the cost of specificity and positive predictive value, which may enable early rule in/out of AMI in patients with chest pain. Baseline hs-cTn elevation in the setting of negative cTn is also associated with increased nonfatal myocardial infarction or death during follow-up.

Renin-angiotensin system antagonists and clinical outcomes in stable coronary artery disease without heart failure.

AIMS: The aim of this study was to determine whether angiotensin-converting enzyme inhibitor (ACEI) or angiotensin-II receptor blocker (ARB) use is associated with lower rates of cardiovascular events in patients with stable coronary artery disease (CAD) but without heart failure (HF) receiving contemporary medical management. METHODS AND RESULTS: Using data from the Reduction of Atherothrombosis for Continued Health (REACH) registry, we examined, using propensity score approaches, relationships between cardiovascular outcomes and ACEI/ARB use (64.1% users) in 20 909 outpatients with stable CAD and free of HF at baseline. As internal control, we assessed the relation between statin use and outcomes. At 4-year follow-up, the risk of cardiovascular death, MI, or stroke (primary outcome) was similar in ACEI/ARB users compared with non-users (hazard ratio, 1.03; 95% confidence interval [CI], 0.91-1.16; P = 0.66). Similarly, the risk of the primary outcome and cardiovascular hospitalization for atherothrombotic events (secondary outcome) was not reduced in ACEI/ARB users (hazard ratio, 1.08; 95% CI, 1.01-1.16; P = 0.04), nor were the rates of any of its components. Analyses using propensity score matching yielded similar results, as did sensitivity analyses accounting for missing covariates, changes in medications over time, or analysing separately ACEI and ARB use. In contrast, in the same cohort, statin use was associated with lower rates for all outcomes. CONCLUSIONS: Use of ACEI/ARB was not associated with better outcomes in stable CAD outpatients without HF. The benefit of ACEI/ARB seen in randomized clinical trials was not replicated in this large contemporary cohort, which questions their value in this specific subset.

Cardiac arrhythmias and conduction defects in systemic sclerosis.

Signs and symptoms of arrhythmias or conduction defects are frequently reported in patients with SSc. These rhythm disorders may have several origins (i.e., related to primary heart involvement, pericardial disease, valvular regurgitation or pulmonary arterial hypertension) and may negatively affect the overall prognosis of these patients. It is therefore important to identify patients at high risk for cardiac arrhythmias with a complete cardiological evaluation and to identify the underlying heart disease, including SSc-related myocardial involvement. In addition, some therapeutic options in SSc patients may differ from those recommended in other populations.

[Natriuretic peptides in the diagnosis and monitoring of heart failure]. / Peptides natriurétiques dans le diagnostic et le suivi de l'insuffisance cardiaque.

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.

In-hospital Prognostic Value of TAPSE/sPAP in Patients Hospitalized for Acute Heart Failure.

AIMS: TAPSE/sPAP (tricuspid annular plane systolic excursion over systolic pulmonary artery pressure) assessed by echocardiography appears to be a good noninvasive 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: 333 consecutive patients (mean age 68 ± 14 years, 70% of male, mean LVEF 44 ± 16%) hospitalized for AHF across 39 French cardiology department, with TAPSE/sPAP measured by echocardiography within the 24 first hours 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 characteristics curves analysis, the best TAPSE/sPAP threshold for in-hospital MACEs was 0.40 mm/mmHg. TAPSE/sPAP <0.40 mm/mmHg was independently associated with in-hospital MACEs, even after adjustment with comorbidities (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; Chi-2 improvement: 14.4; LR-test p < 0.001). These results were consistent in an external validation cohort of 133 patients. CONCLUSION: TAPSE/sPAP < 0.40 mm/mmHg assessed by an early echocardiography during an AHF episode is independently associated with in-hospital MACEs suggesting enhanced close monitoring and strengthened HF-specific care in these patients. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05063097.

TAPSE/sPAP prognostic value for In-Hospital Adverse Events in Patients Hospitalized for Acute Coronary Syndrome.

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.

High-sensitivity cardiac troponin in the distinction of acute myocardial infarction from acute cardiac noncoronary artery disease.

BACKGROUND: We hypothesized that high-sensitivity cardiac troponin (hs-cTn) and its early change are useful in distinguishing acute myocardial infarction (AMI) from acute cardiac noncoronary artery disease. METHODS AND RESULTS: In a prospective, international multicenter study, hs-cTn was measured with 3 assays (hs-cTnT, Roche Diagnostics; hs-cTnI, Beckman-Coulter; hs-cTnI Siemens) in a blinded fashion at presentation and serially thereafter in 887 unselected patients with acute chest pain. Accuracy of the combination of presentation values with serial changes was compared against a final diagnosis adjudicated by 2 independent cardiologists. AMI was the adjudicated final diagnosis in 127 patients (15%); cardiac noncoronary artery disease, in 124 (14%). Patients with AMI had higher median presentation values of hs-cTnT (0.113 µg/L [interquartile range, 0.049-0.246 µg/L] versus 0.012 µg/L [interquartile range, 0.006-0.034 µg/L]; P<0.001) and higher absolute changes in hs-cTnT in the first hour (0.019 µg/L [interquartile range, 0.007-0.067 µg/L] versus 0.001 µg/L [interquartile range, 0-0.003 µg/L]; P<0.001) than patients with cardiac noncoronary artery disease. Similar findings were obtained with the hs-cTnI assays. Adding changes of hs-cTn in the first hour to its presentation value yielded a diagnostic accuracy for AMI as quantified by the area under the receiver-operating characteristics curve of 0.94 for hs-cTnT (0.92 for both hs-cTnI assays). Algorithms using ST-elevation, presentation values, and changes in hs-cTn in the first hour accurately separated patients with AMI and those with cardiac noncoronary artery disease. These findings were confirmed when the final diagnosis was readjudicated with the use of hs-cTnT values and validated in an independent validation cohort. CONCLUSION: The combined use of hs-cTn at presentation and its early absolute change excellently discriminates between patients with AMI and those with cardiac noncoronary artery disease.

Comparison of the performances of cardiac troponins, including sensitive assays, and copeptin in the diagnostic of acute myocardial infarction and long-term prognosis between women and men.

BACKGROUND: Concerns have been raised about possible gender disparities in cardiac investigations and/or outcome. This study sought to examine and compare the diagnostic and prognostic performance of selected cardiac biomarkers in women versus men. METHODS: In a prospective, multicenter cohort of patients with acute chest pain cardiac troponin T (cTnT) (fourth-generation Roche assay), high-sensitivity cTnT (hs-cTnT), and copeptin were measured at presentation. RESULTS: Of 1,247 patients, 420 were women and 827 were men. Although the rate of acute myocardial infarction was similar in women (14.5%) and men (16.6%, P = .351), women more frequently had cardiac but noncoronary causes of chest pain (17.4% vs 10.8%, P = .001) and less frequently had unstable angina (8.8% vs 16.6%, P = .002) than men. Diagnostic accuracy as quantified by the area under the receiver operating characteristic curve (AUC) for acute myocardial infarction in women was 0.90 (95% CI 0.84-0.95) for cTnT, which was lower than the AUC for hs-cTnT alone (0.94, 95% CI [0.91-0.98]), the combination of cTnT with copeptin (0.96, 95% CI [0.94-0.98]) or the combination of hs-cTnT with copeptin (0.96, 95% CI [0.93-0.98]) (P = .008, P = .006, and P = .002, respectively). Prognostic accuracy as quantified by the AUCs for 1-year mortality was 0.69 (0.56-0.83), 0.86 (0.79-0.93), 0.87 (0.81-0.94), and 0.87 (0.80-0.94), respectively. No relevant gender differences in AUCs were observed. CONCLUSION: The diagnostic and prognostic performance of cTnT, hs-cTnT, and copeptin is as good in women as in men. High-sensitivity cTnT and the combination of cTnT and copeptin outperform cTnT alone, both in women and men.

Optimisation of treatments for heart failure with reduced ejection fraction in routine practice: a position statement from a panel of experts.

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.

Takotsubo syndrome occurring in systemic diseases: A French multicenter retrospective case-control study and literature review.

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.

Angiogenic biomarkers predict the occurrence of digital ulcers in systemic sclerosis.

OBJECTIVE: To evaluate the possible merit of endothelial markers for the prediction of ischaemic digital ulcers in patients with systemic sclerosis (SSc). METHODS: Circulating endothelial progenitor cells (EPC), circulating endothelial cells and serum levels of placental growth factor (PlGF), soluble vascular adhesion molecule and vascular endothelial growth factor were measured in a prospective cohort of 100 SSc patients. The primary outcome was the occurrence of one or more new ischaemic digital ulcers during a planned 3-year follow-up. RESULTS: After the follow-up period, 17 patients developed new digital ulcers. By multivariate analysis focused on biomarkers, high PlGF serum levels and low EPC counts were identified as predictors of the occurrence of at least one new digital ulcer. In a secondary model including biomarkers together with clinical SSc characteristics all predictors of digital ulcers defined by p≤0.1 in univariate analysis, high PlGF serum levels (HR 7.26, 95% CI 1.92 to 27.41) and a history of digital ulcers (HR 9.32, 95% CI 1.51 to 59.83) were identified as independent predictors of a new digital ulcer. In an alternative model excluding patients with a history of digital ulcers at baseline, high PlGF serum levels (HR 13.46, 95% CI 1.58 to 114.73) and low EPC counts (HR 7.95, 95% CI 2.09 to 30.09) remained predictive of new digital ulcer occurrence during follow-up. CONCLUSION: This study identified high PlGF serum levels and low circulating EPC counts as predictors of new digital ulcers in SSc. It highlights the critical role of angiogenesis in this vascular outcome. These markers may improve digital ulcer risk stratification and therefore allow earlier therapeutic intervention.
