RESUMEN

BACKGROUND: ST-segment-elevation myocardial infarction (STEMI) guidelines recommend pharmaco-invasive treatment if timely primary percutaneous coronary intervention (PCI) is unavailable. Full-dose tenecteplase is associated with an increased risk of intracranial hemorrhage in older patients. Whether pharmaco-invasive treatment with half-dose tenecteplase is effective and safe in older patients with STEMI is unknown. METHODS: STREAM-2 (Strategic Reperfusion in Elderly Patients Early After Myocardial Infarction) was an investigator-initiated, open-label, randomized, multicenter study. Patients ≥60 years of age with ≥2 mm ST-segment elevation in 2 contiguous leads, unable to undergo primary PCI within 1 hour, were randomly assigned (2:1) to half-dose tenecteplase followed by coronary angiography and PCI (if indicated) 6 to 24 hours after randomization, or to primary PCI. Efficacy end points of primary interest were ST resolution and the 30-day composite of death, shock, heart failure, or reinfarction. Safety assessments included stroke and nonintracranial bleeding. RESULTS: Patients were assigned to pharmaco-invasive treatment (n=401) or primary PCI (n=203). Median times from randomization to tenecteplase or sheath insertion were 10 and 81 minutes, respectively. After last angiography, 85.2% of patients undergoing pharmaco-invasive treatment and 78.4% of patients undergoing primary PCI had ≥50% resolution of ST-segment elevation; their residual median sums of ST deviations were 4.5 versus 5.5 mm, respectively. Thrombolysis In Myocardial Infarction flow grade 3 at last angiography was ≈87% in both groups. The composite clinical end point occurred in 12.8% (51/400) of patients undergoing pharmaco-invasive treatment and 13.3% (27/203) of patients undergoing primary PCI (relative risk, 0.96 [95% CI, 0.62-1.48]). Six intracranial hemorrhages occurred in the pharmaco-invasive arm (1.5%): 3 were protocol violations (excess anticoagulation in 2 and uncontrolled hypertension in 1). No intracranial bleeding occurred in the primary PCI arm. The incidence of major nonintracranial bleeding was low in both groups (<1.5%). CONCLUSIONS: Halving the dose of tenecteplase in a pharmaco-invasive strategy in this early-presenting, older STEMI population was associated with electrocardiographic changes that were at least comparable to those after primary PCI. Similar clinical efficacy and angiographic end points occurred in both treatment groups. The risk of intracranial hemorrhage was higher with half-dose tenecteplase than with primary PCI. If timely PCI is unavailable, this pharmaco-invasive strategy is a reasonable alternative, provided that contraindications to fibrinolysis are observed and excess anticoagulation is avoided.

RESUMEN

BACKGROUND: The use of myocardial reperfusion-mainly via angioplasty-has increased in our region to over 95%. We wondered whether old and very old patients have benefited from this development. METHODS: Setting: Greater Paris Area (Ile-de-France). DATA: Regional registry, prospective, including since 2003, data from 39 mobile intensive care units performing prehospital treatment of patients with ST segment elevation myocardial infarction (STEMI) (<24 h). PARAMETERS: Demographic, decision to perform reperfusion and outcome (in-hospital mortality). PRIMARY ENDPOINT: Reperfusion decision rate by decade over age 70. SECONDARY ENDPOINT: Outcome. RESULTS: We analysed the prehospital management of 27,294 patients. There were 21,311 (78%) men and 5,919 (22%) women with a median age of 61 (52-73 years). Among these patients, 8,138 (30%) were > 70 years, 3,784 (14%) > 80 years and 672 (2%) > 90 years.The reperfusion decision rate was 94%. It decreased significantly with age: 93, 90 and 76% in patients in their seventh, eighth and ninth decade, respectively. The reperfusion decision rate increased significantly over time. It increased in all age groups, especially the higher ones. Mortality was 6%. It increased significantly with age: 8, 16 and 25% in patients in their seventh, eighth and ninth decade, respectively. It significantly decreased over time in all age groups. The odds ratio of the impact of reperfusion decision on mortality reached 0.42 (0.26-0.68) in patients over 90 years. CONCLUSION: the increase in the reperfusion decision rate was the greatest in the oldest patients. It reduced mortality even in patients over 90 years of age.

RESUMEN

BACKGROUND: Recent-onset atrial fibrillation (RAF) is the most frequent supraventricular dysrhythmia in emergency medicine. Severely compromised patients require acute treatment with injectable drugs OBJECTIVE: The main purpose of this external validity study was to compare the short-term efficacy of esmolol with that of amiodarone to treat severe RAF in an emergency setting. METHODS: This retrospective survey was conducted in mobile intensive care units by analyzing patient records between 2002 and 2013. We included RAF with (one or more) severity factors including: clinical shock, angina pectoris, ST shift, and very rapid ventricular rate. A blind matching procedure was used to constitute esmolol group (n = 100) and amiodarone group (n = 200), with similar profiles for age, gender, initial blood pressure, heart rate, severity factors, and treatment delay. The main outcome measure was the percentage of patients with a ventricular rate control defined as heart frequency ≤ 100 beats/min. More stringent (rhythm control) and more humble indicators (20% heart rate reduction) were analyzed at from 10 to 120 min after treatment initiation. RESULTS: Patient characteristics were comparable for both groups: age 66 ± 16 years, male 71%, treatment delay < 1 h 36%, 1-2 h 29%, > 2 h 35%, chest pain 61%, ST shift 62%, ventricular rate 154 ± 26 beats/min, and blood pressure 126/73 mm Hg. The superiority of esmolol was significant at 40 min (64% rate control with esmolol vs. 25% with amiodarone) and for all indicators from 10 to 120 min after treatment onset. CONCLUSION: In "real life emergency medicine," esmolol is better than amiodarone in the treatment of RAF.

RESUMEN

BACKGROUND: In-hospital mortality of ST-segment-elevation myocardial infarction (STEMI) has decreased drastically. In contrast, prehospital mortality from sudden cardiac arrest (SCA) remains high and difficult to reduce. Identification of the patients with STEMI at higher risk for prehospital SCA could facilitate rapid triage and intervention in the field. METHODS: Using a prospective, population-based study evaluating all patients with STEMI managed by emergency medical services in the greater Paris area (11.7 million inhabitants) between 2006 and 2010, we identified characteristics associated with an increased risk of prehospital SCA and used these variables to build an SCA prediction score, which we validated internally and externally. RESULTS: In the overall STEMI population (n=8112; median age, 60 years; 78% male), SCA occurred in 452 patients (5.6%). In multivariate analysis, younger age, absence of obesity, absence of diabetes mellitus, shortness of breath, and a short delay between pain onset and call to emergency medical services were the main predictors of SCA. A score built from these variables predicted SCA, with the risk increasing 2-fold in patients with a score between 10 and 19, 4-fold in those with a score between 20 and 29, and >18-fold in patients with a score ≥30 compared with those with scores <10. The SCA rate was 28.9% in patients with a score ≥30 compared with 1.6% in patients with a score ≤9 (P for trend <0.001). The area under the curve values were 0.7033 in the internal validation sample and 0.6031 in the external validation sample. Sensitivity and specificity varied between 96.9% and 10.5% for scores ≥10 and between 18.0% and 97.6% for scores ≥30, with scores between 20 and 29 achieving the best sensitivity and specificity (65.4% and 62.6%, respectively). CONCLUSIONS: At the early phase of STEMI, the risk of prehospital SCA can be determined through a simple score of 5 routinely assessed predictors. This score might help optimize the dispatching and management of patients with STEMI by emergency medical services.

RESUMEN

BACKGROUND: It is not known whether prehospital fibrinolysis, coupled with timely coronary angiography, provides a clinical outcome similar to that with primary percutaneous coronary intervention (PCI) early after acute ST-segment elevation myocardial infarction (STEMI). METHODS: Among 1892 patients with STEMI who presented within 3 hours after symptom onset and who were unable to undergo primary PCI within 1 hour, patients were randomly assigned to undergo either primary PCI or fibrinolytic therapy with bolus tenecteplase (amended to half dose in patients ≥75 years of age), clopidogrel, and enoxaparin before transport to a PCI-capable hospital. Emergency coronary angiography was performed if fibrinolysis failed; otherwise, angiography was performed 6 to 24 hours after randomization. The primary end point was a composite of death, shock, congestive heart failure, or reinfarction up to 30 days. RESULTS: The primary end point occurred in 116 of 939 patients (12.4%) in the fibrinolysis group and in 135 of 943 patients (14.3%) in the primary PCI group (relative risk in the fibrinolysis group, 0.86; 95% confidence interval, 0.68 to 1.09; P=0.21). Emergency angiography was required in 36.3% of patients in the fibrinolysis group, whereas the remainder of patients underwent angiography at a median of 17 hours after randomization. More intracranial hemorrhages occurred in the fibrinolysis group than in the primary PCI group (1.0% vs. 0.2%, P=0.04; after protocol amendment, 0.5% vs. 0.3%, P=0.45). The rates of nonintracranial bleeding were similar in the two groups. CONCLUSIONS: Prehospital fibrinolysis with timely coronary angiography resulted in effective reperfusion in patients with early STEMI who could not undergo primary PCI within 1 hour after the first medical contact. However, fibrinolysis was associated with a slightly increased risk of intracranial bleeding. (Funded by Boehringer Ingelheim; ClinicalTrials.gov number, NCT00623623.).

RESUMEN

BACKGROUND: In the Strategic Reperfusion Early After Myocardial Infarction (STREAM) trial, a pharmaco-invasive (PI) strategy was compared with primary percutaneous coronary intervention (pPCI) in ST-segment-elevation myocardial infarction patients presenting within 3 hours after symptom onset but unable to undergo pPCI within 1 hour. At 30 days, the PI approach was associated with a nominally but nonstatistically significant lower incidence of the composite primary end point of death, shock, congestive heart failure, and reinfarction when compared with pPCI. The aim of the present study was to determine the effect of these strategies on 1-year mortality. METHODS AND RESULTS: Vital status at 1 year was available in 936 of 944 (99.2%) and 941 of 948 (99.3%) patients in the PI and pPCI arm, respectively. At 1 year, all-cause mortality rates (6.7% versus 5.9%) were similar for PI and pPCI-treated patients (P=0.49; risk ratio, 1.13; 95% confidence interval, 0.79-1.62). Cardiac mortality rates were similar as well (4.0% versus 4.1%, P=0.93; risk ratio, 0.98; 95% confidence interval, 0.62-1.54). Overall, only 34 patients died between day 30 and 1 year, 20 in the PI arm and 14 in the pPCI arm, of whom 20 died of noncardiac reasons (13 in the PI and 7 in the pPCI arm). There was no significant difference in 1-year all-cause mortality between the 2 groups among the prespecified key subgroups. CONCLUSIONS: At 1 year, mortality rates in the PI and pPCI arms were similar in ST-segment-elevation myocardial infarction patients presenting within 3 hours after symptom onset and unable to undergo pPCI within 1 hour.

RESUMEN

BACKGROUND: Elderly patients with ST-segment elevation myocardial infarction (STEMI) have worse outcomes and a greater risk of intracranial bleeding than nonelderly patients. Baseline characteristics, clinical outcomes, and the relationship of the tenecteplase (TNK) dose reduction to the efficacy, safety, and electrocardiographic indicators of reperfusion efficacy were evaluated in STEMI patients ≥75 years. METHODS: The STREAM trial evaluated early presenting STEMI patients who could not undergo primary percutaneous coronary intervention within 1 hour of first medical contact. Because of excess intracranial hemorrhage (ICH) in patients ≥75 years, the dose of TNK was reduced by 50%. RESULTS: Before dose amendment, there were 3 (7.1%) of 42 elderly patients with ICH; 2 of these were fatal, whereas no ICH occurred in the 93 elderly patients who received half-dose TNK postamendment. The median extent of ST-segment elevation resolution (≥50%) and proportion of patients with ≥2 mm in the electrocardiogram lead with greatest ST-segment elevation was comparable in elderly patients preamendment and postamendment (63.2% vs 56.0% and 43.6% vs 40.0%, respectively). Patients requiring rescue coronary intervention after TNK was also similar (42.9% vs 44.1%). The primary composite end point (30-day all-cause death, cardiogenic shock, congestive heart failure, and reinfarction) was 31.0% before versus 24.7% postamendment. CONCLUSIONS: Our data, from a modest-sized population of elderly STEMI patients, indicate that half-dose TNK reduces the likelihood of ICH without compromising reperfusion efficacy. These observations are hypothesis generating and warrant further confirmation in randomized clinical trials in the elderly.

RESUMEN

The e-MUST registry has continuously and comprehensively documented ST-segment elevation myocardial infarctions (STEMIs) managed in the prehospital setting by the 39 Mobile Emergency and Resuscitation Services (SMUR) of the 8 Emergency Medical Assistance System (SAMU) and subsequently managed in the 36 interventional cardiology services in Île-de-France since 2000. This encompasses a population of over 12 million residents. To date, nearly 44,000 patients have been enrolled. The analysis of these findings reflects the real-world management of these patients and the evolution of their care. The results are shared annually with the investigators' teams and have led to around twenty publications. The latest acquired results have demonstrated, in a series of over 630 patients aged over 90, that nonagenarians particularly benefit from prehospital coronary reperfusion decisions, resulting in a nearly 60% reduction in mortality.

RESUMEN

OBJECTIVE: Assessment of suicidal risk is one of the most challenging tasks faced by health professionals, notably in emergency care. We compared telephone suicide risk assessment at prehospital Emergency Medical Services Dispatch Center (EMS-DC), with subsequent face-to-face evaluation at Psychiatric Emergency Service (PES), using French national Risk-Urgency-Danger standards (RUD). METHOD: Data were collected for all suicidal adult patients (N = 80) who were addressed by EMS-DC to PES between December 2018 and August 2019 and benefited from RUD assessment at both services. Suicidal risk was given a score of 1, 2, 3 or 4, in order of severity. RESULTS: Mean of the differences between the RUD score at EMS-DC and PES was -0.825 (SD = 1.19), and was found to be significant (p < 0.01). The average time between RUD assessments was 420 min (SD = 448) and was negatively correlated with the difference in the RUD score (r = -0.295, p = 0.008). Associated suicide attempt increased the odds of a decrease in the RUD score (OR = 2.989; 95% CI = 1.141-8.069; p < 0.05). CONCLUSIONS: Telephone evaluation of suicidal risk using RUD at EMS-DC yielded moderately higher scores than those obtained by a subsequent face-to face evaluation at PES, with this difference partially explained by the time between assessments, and by clinical and contextual factors.

RESUMEN

BACKGROUND: Primary care improvement is the cornerstone of current reforms. Mental disorders (MDs) are a leading cause of morbidity worldwide and widespread in industrialised countries. MDs are treated mainly in primary care by general practitioners (GPs), even though the latter ability to detect, diagnose, and treat patients with MDs is often considered unsatisfactory. This article examines GPs' management of MDs in an effort to acquire more information regarding means by which GPs deal with MD cases, impact of such cases on their practices, factors that enable or hinder MD management, and patient-management strategies. METHODS: This study employs a mixed-method approach with emphasis on qualitative investigation. Based on a previous survey of 398 GPs in Quebec, Canada, 60 GPs representing a variety of practice settings were selected for further study. A 10-minute-long questionnaire comprising 27 items was administered, and 70-minute-long interviews were conducted. Quantitative (SPSS) and qualitative (NVivo) analyses were performed. RESULTS: At least 20% of GP visits were MD-related. GPs were comfortable managing common MDs, but not serious MDs. GPs' based their treatment of MDs on pharmacotherapy, support therapy, and psycho-education. They used clinical intuition with few clinical tools, and closely followed their patients with MDs. Practice features (salary or hourly fees payment; psycho-social teams on-site; strong informal networks), and GPs' individual characteristics (continuing medical education; exposure and interest in MDs; traits like empathy) favoured MD management. Collaboration with psychologists and psychiatrists was considered key to good MD management. Limited access to specialists, system fragmentation, and underdeveloped group practice and shared-care models were impediments. MD management was seen as burdensome because it required more time, flexibility, and emotional investment. Strategies exist to reduce the burden (one-problem-per-visit rule; longer time slots). GPs found MD practice rewarding as patients were seen as grateful and more complying with medical recommendations compared to other patients, generally leading to positive outcomes. CONCLUSIONS: To improve MD management, this study highlights the importance of extending multidisciplinary GP practice settings with salary or hourly fee payment; access to psychotherapeutic and psychiatric expertise; and case-discussion training involving local networks of GPs and MD specialists that encourage both knowledge transfer and shared care.

RESUMEN

During winter 2020-2021, France and other European countries were severely affected by highly pathogenic avian influenza H5 viruses of the Gs/GD/96 lineage, clade 2.3.4.4b. In total, 519 cases occurred, mainly in domestic waterfowl farms in Southwestern France. Analysis of viral genomic sequences indicated that 3 subtypes of HPAI H5 viruses were detected (H5N1, H5N3, H5N8), but most French viruses belonged to the H5N8 subtype genotype A, as Europe. Phylogenetic analyses of HPAI H5N8 viruses revealed that the French sequences were distributed in 9 genogroups, suggesting 9 independent introductions of H5N8 from wild birds, in addition to the 2 introductions of H5N1 and H5N3.

RESUMEN

When epidemic cholera appeared in Haiti in October 2010, the medical community there had virtually no experience with the disease and needed rapid training as the epidemic spread throughout the country. We developed a set of training materials specific to Haiti and launched a cascading training effort. Through a training-of-trainers course in November 14-15, 2010, and department-level training conducted in French and Creole over the following 3 weeks, 521 persons were trained and equipped to further train staff at the institutions where they worked. After the training, the hospitalized cholera patients' case-fatality rate dropped from 4% to <2% by mid-December and was <1% by January 2011. Continuing in-service training, monitoring and evaluation, and integration of cholera management into regular clinical training will help sustain this success.

RESUMEN

Managing a patient with chest pain suspected to be a ST segment elevation myocardial infarction is a race against time. This management is based on a chain, like what is presented for cardiac arrest. Three phases follow one another, with potential loss of time successively attributable to the patient, the emergency physician and then the cardiologist. It would be tempting to consider that the main culprit in the event of delayed treatment is the patient. This review is the opportunity to show that it is not the case. The emergency physician, the cardiologist and their interconnection are the main providers of delay and, as such, the main enemies of myocardial reperfusion.

RESUMEN

Background and Purpose: Ischemic stroke is one of the most common causes of morbidity and mortality and has numerous clinical mimics. Previous studies have suggested a potential role of the tryptophan-serotonin (5-HT)-kynurenine (TSK) axis in ischemic stroke. Studies assessing this axis in the hyperacute phase of ischemic stroke (<4.5 h) are lacking. This prospective study thus evaluates the TSK axis in transient ischemic attack (TIA) and hyperacute ischemic stroke (AIS) patients. Methods: This study included 28 patients (24 AIS and 4 TIA) and 29 controls. The blood and urine samples of patient were collected within 4.5 h of symptoms onset (day 0, D0), then at 24 h and 3 months. Control blood and urine samples were collected once (D0). The TSK axis markers measured were platelet serotonin transporter (SERT) and 5-HT2A receptor (5-HT2AR) densities and platelet, plasma, and urinary 5-HT, plasma and urinary 5-hydroxyindole acetic acid (5-HIAA), and plasma kynurenine and tryptophan (TRP) levels. Results: At D0, patients exhibited a lower (p = 10-5) platelet SERT density, higher (p < 10-6) platelet 5-HT2AR density, higher (p = 10-5) plasma kynurenine/tryptophan (K/T) ratio, and higher urinary 5-HT (p = 0.011) and 5-HIAA (p = 0.003) levels than controls. Conclusions: We observed, for the first time, a hyperacute dysregulation of the serotonergic axis, and hyperacute and long-lasting activation of the tryptophan-kynurenine pathway in brain ischemia.

RESUMEN

BACKGROUND: The time lapse between onset of symptoms and a call to an emergency dispatch center (pain-to-call time) is a critical prognostic factor in patients with chest pain. It is therefore important to identify factors related to delays in calling for help. OBJECTIVES: To analyze whether age, gender, or time of day influence the pain-to-call delay in patients with acute STsegment elevation myocardial infarction (STEMI). MATERIAL AND METHODS: Data were extracted from a prospective registry of STEMI cases managed by 39 mobile intensive care ambulance teams before hospital arrival within 24 hours of onset in our region, the greater metropolitan area of Paris, France. We analyzed the relation between pain-to-call time and the following factors: age, gender, and the time of day when symptoms appeared. We also assessed the influence of pain-to-call time on the rate of prehospital decisions to implement reperfusion therapy. RESULTS: A total of 24 662 consecutive patients were included; 19 291 (78%) were men and 4371 (22%) were women. The median age was 61 (interquartile range, 52-73) years (men, 59 [51-69] years; women, 73 [59-83] years; P .0001). The median pain-to-call time was 60 (24-164) minutes (men, 55 [23-150] minutes; women, 79 [31-220] minutes; P .0001). The delay varied by time of day from a median of 40 (17-101) minutes in men between 5 pm and 6 pm to 149 (43-377) minutes in women between 2 am and 3 am. The delay was longer in women regardless of time of day and increased significantly with age in both men and women (P .001). A longer pain-to-call time was significantly associated with a lower rate of implementation of myocardial reperfusion (P .001). CONCLUSION: Pain-to-call delays were longer in women and older patients, especially at night. These age and gender differences identify groups that would benefit most from health education interventions.


INTRODUCCION: En el dolor torácico, el tiempo desde el inicio de los síntomas hasta el aviso al sistema de emergencias (TAE) es un factor pronóstico decisivo. Es necesario conocer los factores que pueden influir en su duración. OBJETIVO: Analizar el efecto de la edad, el sexo y el momento del día en el TAE en pacientes con infarto agudo de miocardio con elevación del segmento ST (IAMEST). METODO: Se analizaron los datos de un registro regional prospectivo que incluye a todos los pacientes con IAMEST y 24 horas de evolución atendidos por 39 equipos de ambulancias de soporte vital avanzado en un entorno prehospitalario en el área metropolitana de París, Francia. Se analizó el TAE en relación con la edad, el sexo y el momento de aparición de los síntomas. Se valoró la influencia del TAE en la decisión prehospitalaria de tratamiento de reperfusión. RESULTADOS: Se incluyeron 24.662 pacientes consecutivos, de los cuales 19.291 (78%) eran hombres; la edad mediana fue de 61 años (RIC 52-73); 59 (51-69) en hombres y 73 (59-83) en mujeres (p 0,0001). El TAE fue de 60 minutos (24-164); 55 (23-150) minutos en hombres y 79 (31-220) minutos en mujeres (p 0,0001), y oscilaba entre 40 (17-101) minutos en hombres entre las 17:00 y las 18:00 y 149 (43-377) en mujeres entre las 02:00 y las 03:00. Independientemente de la hora de aparición del dolor, el TAE fue mayor en mujeres, y aumentó con la edad, tanto en hombres como en mujeres (p 0,001). El TAE prolongado se asoció con un descenso significativo en la decisión prehospitalaria de tratamiento de reperfusión (p 0,001). CONCLUSIONES: El intervalo de TAE fue más largo en mujeres y pacientes mayores, especialmente por la noche. Estos resultados permiten identificar los grupos de pacientes que más se beneficiarían de medidas de educación sanitaria.

RESUMEN

OBJECTIVES: Few outcome data are available about convulsive status epilepticus managed in the intensive care unit. We studied 90-day functional outcomes and their determinants in patients with convulsive status epilepticus. DESIGN: Two hundred forty-eight convulsive status epilepticus patients admitted to 18 intensive care units in 2005-2007 were included in a prospective observational cohort study. The main outcome measure was a Glasgow Outcome Scale score of 5 (good recovery) on day 90. MAIN RESULTS: Convulsive status epilepticus occurred out of hospital in 177 (67%) patients, and all but 15 patients were still seizing at medical team arrival. The median time from convulsive status epilepticus onset to anticonvulsant drug initiation was 40 mins (interquartile range, 5-80). Total seizure duration was 85 mins (interquartile range, 46.5-180). Convulsive status epilepticus was refractory in 49 (20%) patients. The most common causes of convulsive status epilepticus were anticonvulsive agent withdrawal (36.4%) in patients with previous epilepsy and stroke (27.7%) in inaugural convulsive status epilepticus. Mechanical ventilation was needed in 210 (85%) patients. On day 90, 42 (18.8%) patients were dead, 87 (38.8%) had marked functional impairments (Glasgow Outcome Scale score, 2-4), and 95 (42.4%) had a good recovery (Glasgow Outcome Scale score, 5). Factors showing independent positive associations with poor outcome (Glasgow Outcome Scale score, <5) were older age (odds ratio, 1.04/year; 95% confidence interval, 1.02-1.05; p=.0005), cerebral insult (odds ratio, 2.70; 95% confidence interval, 1.37-5.26; p=.007), longer seizure duration (odds ratio, 1.72/120 min; 95% confidence interval, 1.05-2.86; p=.03), on-scene focal neurologic signs (odds ratio, 2.08; 95% confidence interval, 1.03-4.16; p=.04), and refractory convulsive status epilepticus (odds ratio, 2.70; 95% confidence interval, 1.02-7.14; p=.045). CONCLUSIONS: Ninety days after intensive care unit admission for convulsive status epilepticus, half the survivors had severe functional impairments. Longer seizure duration, cerebral insult, and refractory convulsive status epilepticus were strongly associated with poor outcomes, suggesting a role for early neuroprotective strategies.

RESUMEN

BACKGROUND: Our purpose was to describe the care pathway of patients hospitalized for acute heart failure (AHF) and investigate whether a management involving a cardiology department had an impact on in-hospital mortality. METHODS: Between June 2014 and October 2018, we included patients hospitalized for AHF in 24 French hospitals. Characteristics of the episode, patient's care pathway and outcomes were recorded on a specific assessment tool. The primary outcome was the association between patient care pathway and in-hospital mortality. The independent association between admission to a cardiology ward and in-hospital mortality was assessed through a multivariate regression model and propensity score matching. RESULTS: A total of 3677 patients, mean age of 78, were included. The in-hospital mortality rate was 8% (n = 287) and was associated on multivariate regression with advanced age, presence of sepsis, of cardiogenic shock, high New York Heart Association (NYHA) score and increased plasma creatinine level on admission. High blood pressure and admission to a cardiology department appeared as protective factors. After propensity score matching, hospitalization in a cardiology department remained a protective factor of in-hospital mortality (OR = 0.61 [0.44-0.84], p = 0.002). CONCLUSION: A hospital course of care involving a cardiology department was associated with an increase in hospital survival in AHF patients. These finding may highlight the importance of collaboration between cardiologists and other in-hospitals specialties, such as emergency physicians, in order to find the best in-hospital pathway for patients with AHF.Clinical Trial NCT03903198.
