RESUMEN
BACKGROUND AND AIMS: Complex aortic atheroma (CAA) is a common cause of acute brain ischemia (BI), including ischemic stroke (IS) and transient ischemic attack (TIA), and is associated with recurrence. The CHA2DS2-VASc score is a useful tool for predicting stroke in patients with atrial fibrillation (AF), and can also predict cardiovascular events in other populations, including non-AF populations. The ADAM-C score is a new risk score for predicting the diagnostic yield of transesophageal echocardiography (TEE) after BI. We aimed to evaluate the ability of CHA2DS2-VASc and ADAM-C scores to predict CAA after BI. METHODS: This prospective, multicenter, observational study included 1479 patients aged over 18 years who were hospitalized for BI. CAA was defined as the presence of one or more of the following criteria: thrombus, ulcerated plaque, or plaque thickening ≥ 4 mm. RESULTS: CAA was diagnosed in 216 patients (14.6%). CHA2DS2-VASc and ADAM-C scores were significantly higher in the CAA group versus the non-CAA group (P < .0001 for both). The CHA2DS2-VASc and ADAM-C scores appear to be good predictors of CAA (AUC 0.699 [0.635, 0.761] and 0.759 [0.702, 0.814], respectively). The sensitivity, specificity, predictive positive value (PPV), and negative predictive value (NPV) of the scores for detecting CAA were 94%, 22%, 17%, and 96%, respectively, for a CHA2DS2-VASc score < 2, and 90%, 46%, 22%, and 96%, respectively, for an ADAM-C score < 3 CONCLUSIONS: CHA2DS2-VASc and ADAM-C scores are able to predict CAA after BI. CHA2DS2-VASc < 2 and ADAM-C < 3 both have an interesting NPV of 96%.

BACKGROUND AND AIM: The clinical utility of transesophageal echocardiography (TEE) after brain ischemia (BI) remains a matter of debate. We aimed to evaluate the clinical impact of TEE and to build a score that could help physicians to identify which patients should better benefit from TEE. METHODS: This prospective, multicenter, observational study included patients over 18 years old, hospitalized for BI. TEE findings were judged discriminant if the results showed important information leading to major changes in the management of patients. Most patients with patent foramen ovale were excluded. Variables independently associated with a discriminant TEE were used to build the prediction model. RESULTS: Of the entire population (1479 patients), 255 patients (17%) were classified in the discriminant TEE group. Five parameters were selected as predictors of a discriminant TEE. Accordingly, the ADAM-C score could be calculated as follows: Score = 4 (if age ≥60) + 2 (if diabetes) + 2 (if aortic stenosis from any degrees) + 1 (if multi-territory stroke) + 2 (if history of coronary artery disease). At a threshold lower than 3, the sensitivity, specificity, positive predictive value, and negative predictive value (NPV) of detecting discriminant TEE were 88% (95% CI 85-90), 44% (95% CI 41-47), 21% (95% CI 19-27), and 95% (95% CI 94-97), respectively. CONCLUSION: A simple score based on clinical and transthoracic echocardiographic parameters can help physicians to identify patients who might not benefit from TEE. Indeed, a score lower than 3 has an interesting NPV of 95% (95% CI 94-97).

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: A total of 481 consecutive patients hospitalized in intensive cardiac care unit [mean age 65 ± 13 years, 73% of male, 46% ST-elevation myocardial infarction (STEMI)] for ACS [either STEMI or non-STEMI (NSTEMI)] with TAPSE/sPAP available were included in this prospective French multicentric study (39 centres). 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. Receiver operating characteristic curve analysis identified 0.55â 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 [odds ratio (OR): 19.1, 95% confidence interval (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 χ2 improvement: 52.8; likelihood ratio 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.

We describe a previously unreported and potentially fatal complication of esophageal perforation following cardiopulmonary resuscitation in a 74-year-old man with cardiac arrest subsequent to ventricular tachycardia caused by ischemic heart disease. We discuss the importance of searching for severe traumatic complications. This description emphasizes presenting complaints, early recognition, and management strategies of such cases (Level of Difficulty: Intermediate).
RESUMEN
Recent international guidelines recommend rapid initiation and titration of basic treatments of heart failure but do not explain how to achieve this goal. Despite these recommendations, implementation of treatment in daily practice is poor. This may be partly explained by the profile of the patients (frailty, comorbidities), safety considerations and tolerability issues related to kydney function, low blood pressure or heart rate and hyperkalaemia. In this special article, we intended to help the physician, through an algorithmic approach, to quickly and safely introduce guideline-directed medical therapy in the field of heart failure with ejection fraction under 50%.
RESUMEN
BACKGROUND: To evaluate the association between ventilator type and hospital mortality in patients with acute respiratory distress syndrome (ARDS) related to COVID-19 (SARS-CoV2 infection), a single-center prospective observational study in France. RESULTS: We prospectively included consecutive adults admitted to the intensive care unit (ICU) of a university-affiliated tertiary hospital for ARDS related to proven COVID-19, between March 2020 and July 2021. All patients were intubated. We compared two patient groups defined by whether an ICU ventilator or a less sophisticated ventilator such as a sophisticated turbine-based transport ventilator was used. Kaplan-Meier survival curves were plotted. Cox multivariate regression was performed to identify associations between patient characteristics and hospital mortality. We included 189 patients (140 [74.1%] men) with a median age of 65 years [IQR, 55-73], of whom 61 (32.3%) died before hospital discharge. By multivariate analysis, factors associated with in-hospital mortality were age ≥ 70 years (HR, 2.11; 95% CI, 1.24-3.59; P = 0.006), immunodeficiency (HR, 2.43; 95% CI, 1.16-5.09; P = 0.02) and serum creatinine ≥ 100 µmol/L (HR, 3.01; 95% CI, 1.77-5.10; P < 0.001) but not ventilator type. As compared to conventional ICU (equipped with ICU and anesthesiology ventilators), management in transient ICU (equipped with non-ICU turbine-based ventilators) was associated neither with a longer duration of invasive mechanical ventilation (18 [IQR, 11-32] vs. 21 [13-37] days, respectively; P = 0.39) nor with a longer ICU stay (24 [IQR, 14-40] vs. 27 [15-44] days, respectively; P = 0.44). CONCLUSIONS: In ventilated patients with ARDS due to COVID-19, management in transient ICU equipped with non-ICU sophisticated turbine-based ventilators was not associated with worse outcomes compared to standard ICU, equipped with ICU ventilators. Although our study design is not powered to demonstrate any difference in outcome, our results after adjustment do not suggest any signal of harm when using these transport type ventilators as an alternative to ICU ventilators during COVID-19 surge.
RESUMEN
BACKGROUND: Psychoactive drugs, including illicit drugs, are associated with an increased rate of cardiovascular events. The prevalence and outcome of patients using these drugs at the time of admission to an intensive cardiac care unit is unknown. AIM: To assess the prevalence of psychoactive drugs detected in consecutive patients hospitalized in an intensive cardiac care unit for an acute cardiovascular event. METHODS: This is a nationwide prospective multicentre study, involving 39 centres throughout France, including all consecutive patients hospitalized in an intensive cardiac care unit within 2weeks. Psychoactive drug use will be assessed systematically by urine drug assay within 2hours of intensive cardiac care unit admission, to detect illicit (cannabinoids, cocaine, amphetamines, ecstasy, heroin and other opioids) and non-illicit (barbiturates, benzodiazepines, tricyclic antidepressants, methadone and buprenorphine) psychoactive drugs. Smoking will be investigated systematically by exhaled carbon monoxide measurement, and alcohol consumption using a standardized questionnaire. In-hospital major adverse events, including death, resuscitated cardiac arrest and cardiogenic shock, will be recorded. After discharge, all-cause death and major adverse cardiovascular events will be recorded systematically and adjudicated at 12months of follow-up. RESULTS: The primary outcome will be the prevalence of psychoactive drugs detected by systematic screening among all patients hospitalized in an intensive cardiac care unit. The in-hospital major adverse events will be analysed according to the presence or absence of detected psychoactive drugs. Subgroup analysis stratified by initial clinical presentation and type of psychoactive drug will be performed. CONCLUSIONS: This is the first prospective multicentre study to assess the prevalence of psychoactive drugs detected by systematic screening in consecutive patients hospitalized for acute cardiovascular events.

AIMS: We sought to assess whether global longitudinal strain (GLS) measured early during treatment with anthracyclines (at a cumulative dose of 150 mg/m2) can predict subsequent alterations in left ventricular ejection fraction. METHODS AND RESULTS: Eighty-six patients with Hodgkin's disease, non-Hodgkin's lymphoma, or acute leukaemia and receiving anthracyclines were prospectively included. Patients underwent complete echocardiography on four occasions: baseline (V1); after reaching a cumulative dose of 150 mg/m2 (V2); end of treatment (V3); and 1 year follow-up (V4). Six patients developed cardiotoxicity, defined as a decrease in left ventricular ejection fraction of >10 percentage points, to a value <53%, at V4. GLS measured at V1 and V2 was significantly lower in the cardiotoxicity group vs. the controls (P = 0.042 and P = 0.01, respectively). Compared with GLS at V1, GLS obtained at V2 provided incremental predictive information and appeared to be the strongest predictor of cardiotoxicity (area under the receiver-operating-characteristic curve, 0.82). At a threshold of -17.45% for GLS measured at V2, the sensitivity and specificity of detecting cardiotoxicity were 67% (95% confidence interval 33-100) and 97% (95% confidence interval 94-100), respectively. CONCLUSION: GLS greater than -17.45%, obtained after 150 mg/m2 of anthracycline therapy, is an independent predictor of future anthracycline-induced cardiotoxicity. These findings should encourage physicians to perform echocardiography earlier during treatment with anthracyclines.

This paper shows the eventual benefits of treatment with beta-blockers in post-myocardial infarction. An overview of main clinical trials that have been conducted to test this therapeutic in acute coronary syndrome. In patients presenting with acute myocardial infarction, the early use of intravenous beta-blockers had shown a modest and non significant reduction in mortality. Substantial reductions in mortality and reinfarction have been demonstrated when beta-blockers have been used soon after an acute myocardial infarction and continued long-term. However, these benefits were observed in randomised clinical trials conducted in the 1970s and 1980s, prior to the widespread use of reperfusion therapies and antiplatelet agents. It appears obvious that the long-term use of beta-blockers may be questionable after any acute coronary syndrome especially if complete reperfusion has been achieved and left ventricular function is preserved.

Injection of autologous bone marrow cells into infarcted myocardium has been proposed to limit the deterioration of cardiac function following myocardial infarction (MI); unfortunately, the beneficial effects observed have been modest. One of the limiting factors is believed to be poor local survival of the injected cells, but the potential impact of apoptosis among the injected cells has yet to be assessed. Therefore, this study aimed to quantify the apoptosis rate in bone marrow mononuclear cells (BMMCs) prepared for cardiac therapy, and to analyze their effects in vitro on cardiomyoblast apoptosis and in vivo on cardiac function recovery following MI. Using rabbit BMMCs prepared by Ficoll gradient, apoptotic cells were detected via Annexin V (AnV) staining. The effects of depleting the apoptotic cell population by means of AnV magnetic beads was tested in vitro after coculture with cardiomyoblasts (H9c2 cells) and in vivo after cell injection into the infarcted area. Left ventricular ejection fraction and scar extent were assessed by echography and histology 2 months later. After Ficoll gradient isolation, 37.3% (33.4-37.9%) of BMMCs were found to be apoptotic (Apo(Base) BMMCs). AnV depletion decreased the proportion of apoptotic cells to 20% (17.6-32%) (Apo(Low) BMMCs). Rabbits treated in vivo with Apo(Low) BMMCs after MI presented with significantly improved left ventricular ejection fraction [41.4% (41.0-43.6%) vs. 34.6% (34.6-35.9%), p = 0.03), reduced scar extent [20.4% (17.9-24.3%) vs. 25.6% (17.9-27.9%), p = 0.057], and reduced rate of cardiomyocyte apoptosis compared to those treated with Apo(Base) BMMCs. H9c2 apoptosis was found to be higher after coculture with Apo(Base) than with Apo(Low) BMMCs [25.6% (22.6-29.6%) vs. 10.1% (6.6-12.6%), p = 0.03], a result partially reproduced by cocultures with microparticle-rich supernatants from BMMCs. The presence of apoptotic cells among BMMCs impairs the efficacy of cardiac cell therapy after MI, an effect possibly mediated by apoptotic microparticles.

OBJECTIVE: To report a specific pathophysiology of hemidiaphragmatic paralysis that may result in severe hypoxemia. DESIGN: Case series. SETTING: Intensive care unit in a cardiology hospital. PATIENTS: The series included three patients with refractory hypoxemia in whom a diagnosis of right-to-left-shunt through a patent foramen ovale was made by contrast echocardiography. The three patients had a complete right hemidiaphragmatic paralysis. INTERVENTION: Permanent percutaneous closure of the patent foramen ovale was successfully proceeded in all cases. MAIN RESULT: These procedures resulted in complete normalization of arterial oxygen saturation. CONCLUSION: To our knowledge, only three previous reports have described the association of right-to-left shunt through a patent foramen ovale and hemidiaphragmatic paralysis. Such association may be underestimated.
