ABSTRACT

Resumen El shock cardiogénico (SC) presenta una elevada mortalidad y puede requerir de terapéuticas avanzadas como la asistencia circulatoria mecánica (ACM) y el trasplante cardíaco (TC). Se analizaron en forma retrospectiva, en un único centro, aquellos pacientes que presentaron un infarto agudo de miocardio (IAM), SC y requirieron ACM puente al TC. Entre enero 1997 y junio 2020, 524 pacientes recibieron un TC, 203 por cardiopatía isquémica, 103 en lista de emergencia. Se incluyeron once pacientes con los criterios mencionados (edad media 53 ± 11 años; hombres 73%). Se realizaron 5 angioplastias primarias y 2 cirugías de revascularización miocárdica de urgencia. Cuatro pacientes presentaban anatomía coronaria no pasible de revascularización. Todos recibieron tratamiento inotrópico y vasopresor y requirieron soporte con balón de contrapulsación intra aórtico (BCIA). Dos requirieron el implante de bomba centrífuga univentricular izquierda (BioMedicus®, Medtronic) y 2 de oxigenador de membrana extracorpóreo veno-arterial (ECMO-VA) periférico (Maquet®, Getinge Group). La mediana entre IAM y TC fue 15 días (rango 7-21) y la edad de los donantes 28 ± 11 años. Todos presentaron un IAM extenso (monto necrótico 35 ± 5%) con signos histopatológicos de necrosis transmural e injuria de reperfusión. La mediana de seguimiento fue 9 años (rango 1-15). Ninguno falleció en la internación ni durante el primer año post trasplante. La supervivencia a los 5 y 10 años fue 73% y 55%. El TC en situación de emergencia ha demostrado ser, en nuestro medio, la mejor opción en aquellos pacientes con IAM y SC refractario a la terapia convencional.


Abstract Cardiogenic shock (CS) has a high mortality rate and often requires advanced therapies such as mechanical circulatory support (MCS) and heart transplantation (HT). Those patients who presented an acute myocardial infarction (AMI) with CS and required support through MCS as bridge to HT were retrospectively analyzed in a single Center. Between January 1997 and June 2020, 524 patients received HT, 203 for ischemic-cardiomyopathy, 103 were in emergency waiting list. Eleven patients met the inclusion criteria (mean age 53 ± 11 years old; men 73%). Five primary angioplasties and 2 emergency myocardial revasculariza tion surgeries were performed. Four patients had coronary anatomy not subject to revascularization. All received inotropic and vasopressor treatment and required intra-aortic balloon pump (IABP). Subsequently, two required support with a left univentricular centrifugal pump (BioMedicus®, Medtronic) and two with peripheral veno-arterial extracorporeal membrane oxygenator (VA-ECMO) (Maquet®, Getinge Group). The median between AMI and HT was 15 days (range 7-21) and the mean age of the donors 28 ± 11 years. All had extensive AMI (necrotic amount 35 ± 5%) with histopathological signs of transmural necrosis and reperfusion injury. The median follow-up was 9 years (range 1-15). None died in hospitalization or during the first year after transplantation. Survival at 5 and 10 years was 73% and 55%. Emergency HT may be the best option for selected patients with acute myocardial infarction and cardiogenic shock refractory to conventional therapy.

ABSTRACT

Entre los años 2000 y 2016 en Argentina, se reportaron al Registro Oncopediátrico Hospitalario Argentino (ROHA) 22.450 casos de cáncer en niños menores de 15 años de edad. Las Leucemias constituyen la enfermedad oncológica más frecuente, seguida de los Tumores de Sistema Nervioso Central y los Linfomas. Esta distribución es similar a la descripta en los países desarrollados de Europa y Norteamérica. Su tasa de curación a nivel mundial, llega al 80% debido al uso de quimioterapia intensiva, situación que mejora la supervivencia pero que también aumenta la frecuencia de complicaciones. Estas complicaciones pueden ser debidas tanto al propio cáncer como al tratamiento y en ocasiones ser la primera manifestación de la enfermedad oncológica. Los eventos que amenazan la vida en pacientes inmunocomprometidos son mayores que en la población general, y cuando ocurren tienen una mortalidad elevada. El reconocimiento temprano es clave para el resultado en términos de sobrevida y disminución de la mortalidad. Las acciones deberán centrarse al reconocimiento temprano de eventos críticos en pacientes oncológicos. Los pacientes Hemato-Oncológicos constituyen un gran número de ingresos no planificados a las unidades de cuidados intensivos. Uno de cada 4 pacientes requerirá durante su evolución ingreso a Unidades de Cuidados Intensivos. El propósito de este artículo es describir tres de las urgencias oncológicas que requieren con mayor frecuencia admisión en UCI: la presentación y manejo del shock séptico, Shock Cardiogénico y las complicaciones neurológicas en los pacientes con leucemias agudas (AU)


Between 2000 and 2016, 22,450 cases of cancer in children younger than 15 years of age were reported to the Argentine Hospital Registry of Childhood Cancer (ROHA). Leukemia was the most common cancer reported, followed by central nervous system tumors and lymphoma. This distribution is similar to that described in the developed countries of Europe and North America. The worldwide cure rate is up to 80% due to the use of intensive chemotherapy, which improves survival but also increases the complication rate. These complications may be due both to the cancer itself and to the treatment and are sometimes the first manifestation of the disease. Life-threatening events are more common in immunocompromised patients than in the general population, and when they occur, the mortality rate is high. Early recognition is essential for the outcome in terms of survival and decreased mortality. Interventions should focus on early recognition of critical events in cancer patients. Patients with hematology-oncology diseases account for a large number of unplanned admissions to intensive care units (ICU), while one in four of these patients will require admission to the ICU in the course of their disease. The aim of this study was to describe three oncology emergencies that most frequently require ICU admission: septic shock and its management, cardiogenic shock, and neurological complications in patients with acute leukemia (AU)

ABSTRACT

La membrana de oxigenación extracorpórea arteriovenosa se utiliza cuando ocurre falla hemodinámica y respiratoria refractaria al tratamiento convencional; brinda soporte hemodinamico transitorio, oxigenacion y remocion de CO2, y permite reposo pulmonar. Asimismo ofrece la posibilidad de realizar ventilación ultraprotectiva y evitar la generación de VILI (Ventilation-Induced Lung Injury). No ha sido demostrada su utilización como una terapia frecuente en los casos con insuficiencia hemodinámica secundaria a shock obstructivo por afectación mediastínica. Presentamos el caso de un paciente con shock obstructivo por una masa mediastínica de origen linfoproliferativo tratada con membrana de circulación arteriovenosa extracorpórea.


The arteriovenous extracorporeal membrane is used in patients with hemodynamic and respiratory failure, unresponsive to conventional treatment. It provides transitory hemodynamic support, oxygenation and removal of CO2, allowing pulmonary rest. Moreover it offers the possibility of ultraprotective ventilation and avoids generation of VILI (Ventilation-Induced Lung Injury). It is not frequently used in patients with hemodynamic failure secondary to obstructive shock due to mediastinal compromise. We present the case of a patient with obstructive shock, mediastinal mass of lymphoproliferative origin that was treated with extracorporeal arteriovenous circulation membrane.

ABSTRACT

SUMMARY The treatment of patients with ST-segment elevation myocardial infarction concomitant with the presence of multivessel disease has been studied in several recent studies with the purpose of defining the need, as well as the best moment to approach residual lesions. However, such studies included only stable patients. The best therapeutic approach to cardiogenic shock secondary to acute coronary syndrome, however, remains controversial, but there are recommendations from specialists for revascularization that include non-event related injuries. Recently published, the CULPRIT-SHOCK study showed benefit of the initial approach only of the injury blamed for the acute event, in view of the multivessel percutaneous intervention, in the context of cardiogenic shock. In this perspective, the authors discuss the work in question, regarding methodological questions, limitations and clinical applicability.


RESUMO O tratamento de pacientes com infarto do miocárdio com elevação do segmento ST concomitante à presença de doença multiarterial tem sido estudado em vários estudos recentes com o objetivo de definir a necessidade, bem como o melhor momento, de abordagem das lesões residuais. No entanto, tais estudos incluíam apenas pacientes estáveis. A melhor abordagem terapêutica do choque cardiogênico secundário à síndrome coronariana aguda, no entanto, ainda permanece controversa, havendo porém recomendação de especialistas para uma revascularização que inclua as lesões não relacionadas ao evento. Publicado recentemente, o estudo CULPRIT-SHOCK mostrou benefício da abordagem inicial apenas da lesão culpada pelo evento agudo, perante a intervenção percutânea multiarterial, no contexto do choque cardiogênico. No presente ponto de vista, os autores discutem o trabalho em questão, no que concerne a questões metodológicas, limitações e aplicabilidade clínica.

ABSTRACT

Abstract Takotsubo Cardiomyopathy mainly occurs in postmenopausal women, with or with- out cardiovascular disease, and is commonly associated with emotional or physical stress. After nearly 27 years of extensive efforts towards a better understanding of this disorder, current knowledge remains limited. Many people suffer post-traumatic stress, and this situation can be associated to stress cardiomyopathy. The case is presented of a female who suffers stress asso- ciated with the earthquake of 19 September 2017 in Mexico City, and arrived in the Emergency Department in cardiogenic shock.


Resumen La miocardiopatía de Takotsubo ocurre principalmente en mujeres posmenopáusicas con o sin enfermedad cardiovascular, y se asocia comúnmente con estrés emocional o físico. Después de casi 27 an˜os de esfuerzos extensos para una mejor comprensión de este trastorno, el conocimiento actual sigue siendo limitado. Muchas personas sufren estrés postraumático y esta situación puede estar asociada a la cardiomiopatía por estrés. Presentamos el caso clínico de una mujer que sufrió estrés relacionado con el pasado terremoto del 19 de septiembre en la Ciudad de México y llegó al servicio de urgencias en choque cardiogénico.

ABSTRACT

RESUMO Reportamos o caso de paciente do sexo feminino, 58 anos, sem doença cardíaca conhecida, submetida a transplante hepático sem intercorrências. No segundo dia do pós-operatório desenvolveu choque cardiogênico secundário à miocardiopatia induzida pelo estresse (síndrome de Takotsubo-like). A paciente foi manejada com sucesso com oxigenação por membrana extracorpórea venoarterial periférica, por 6 dias, com recuperação completa da função cardíaca, bem como do enxerto hepático. Síndrome coronariana e miocardite aguda foram excluídas como causas do choque. O uso de oxigenação por membrana extracorpórea neste cenário é possível e seguro, considerando protocolos e tratamento especializado neste tipo de suporte.


ABSTRACT We report the case of a female patient, 58 years of age, without known heart disease, who underwent liver transplantation without complications. On the second postoperative day, the patient developed cardiogenic shock secondary to stress-induced cardiomyopathy (Takotsubo-like syndrome). The patient was successfully managed with veno-arterial peripheral extracorporeal membrane oxygenation for 6 days, with complete recovery of cardiac function and of the hepatic graft. Coronary syndrome and acute myocarditis were excluded as the causes of the shock. The use of extracorporeal membrane oxygenation in this scenario is possible and safe, considering its specialized protocols and treatment.

ABSTRACT

Abstract INTRODUCTION: The mortality due to cardiogenic shock complicating acute myocardial infarction (AMI) is high even in patients with early revascularization. Infusion of low dose recombinant human brain natriuretic peptide (rhBNP) at the time of AMI is well tolerated and could improve cardiac function. OBJECTIVE: The objective of this study was to evaluate the hemodynamic effects of rhBNP in AMI patients revascularized by emergency percutaneous coronary intervention (PCI) who developed cardiogenic shock. METHODS: A total of 48 patients with acute ST segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock and whose hemodynamic status was improved following emergency PCI were enrolled. Patients were randomly assigned to rhBNP (n=25) and control (n=23) groups. In addition to standard therapy, study group individuals received rhBNP by continuous infusion at 0.005 µg kg−1 min−1 for 72 hours. RESULTS: Baseline characteristics, medications, and peak of cardiac troponin I (cTnI) were similar between both groups. rhBNP treatment resulted in consistently improved pulmonary capillary wedge pressure (PCWP) compared to the control group. Respectively, 7 and 9 patients died in experimental and control groups. No drug-related serious adverse events occurred in either group. CONCLUSION: When added to standard care in stable patients with cardiogenic shock complicating anterior STEMI, low dose rhBNP improves PCWP and is well tolerated.

ABSTRACT

Abstract Inotropic drugs are part of the treatment of heart failure; however, inotropic treatment has been largely debated due to the increased incidence of adverse effects and increased mortality. Recently levosimendan, an inotropic positive agent, has been proved to be effective in acute heart failure, reducing the mortality and improving cardiac and renal performance. We report the case of a 75-year-old woman with history of heart and renal failure and hip fracture. Levosimendan was used in preoperative preparation as an adjuvant therapy, to improve cardiac and renal function and to allow surgery.


Resumo Fármacos inotrópicos fazem parte do tratamento de insuficiência cardíaca; no entanto, o tratamento com inotrópicos tem sido amplamente debatido devido ao aumento da incidência de efeitos adversos e da mortalidade. Recentemente, levosimendana, um agente inotrópico positivo, provou ser eficaz na insuficiência cardíaca aguda, reduz a mortalidade e melhora o desempenho cardíaco e renal. Relatamos o caso de uma paciente de 75 anos, com história de insuficiência cardíaca e renal e fratura de quadril. Levosimendana foi usada na preparação do pré-operatório como terapia adjuvante para melhorar a função cardíaca e renal e permitir a cirurgia.

ABSTRACT

Em pacientes com choque cardiogênico pós-infarto a mortalidade é alta. A reversão da hipoperfusão tecidual é essencial para a preservação orgânica durante o período de recuperação funcional do miocárdio. Relatamos o caso de uma paciente que, após seguidos episódios de parada cardiorrespiratória, evoluiu com choque cardiogênico secundário à dissecção espontânea do tronco de coronária esquerda. Após a restauração do fluxo coronariano, por meio da intervenção percutânea primária com uso de stent, optouse pelo implante do dispositivo de assistência circulatória Impella® 2.5, que permitiu melhorar as condições hemodinâmicas da paciente, contribuindo para um desfecho favorável


Mortality is high in patients with post-infarction cardiogenic shock. Reversal of tissue hypoperfusion is essential for organ preservation during the myocardial functional recovery period. The authors report the case of a female patient who, after consecutive episodes of cardiorespiratory arrest, developed cardiogenic shock secondary to spontaneous dissection of the left main coronary artery. After restoration of coronary flow through primary percutaneous intervention with stent implantation, the Impella™ 2.5 circulatory assist device was implanted, which allowed the patient's hemodynamic improvement, contributing to a favorable outcome

ABSTRACT

Mushroom exposures are increasing worldwide. The incidence and fatality of mushroom poisoning are reported to be increasing. Several new syndromes in mushroom poisoning have been described. Rhabdomyolytic mushroom poisoning is one of new syndromes. Russula subnigricans mushroom can cause delayed-onset rhabdomyolysis with acute kidney injury in the severely poisoned patient. There are few reports on the toxicity of R. subnigricans. This report represents the first record of R. subnigricans poisoning with rhabdomyolysis in Korea, describing a 51-year-old man who suffered from rhabdomyolysis, acute kidney injury, severe hypocalcemia, respiratory failure, ventricular tachycardia, cardiogenic shock, and death. Mushroom poisoning should be considered in the evaluation of rhabdomyolysis of unknown cause. Furthermore, R. subnigricans should be considered in the mushroom poisoning with rhabdomyolysis.

ABSTRACT

RESUMO Jovem com 17 anos de idade atendido com dispneia progressiva há 15 dias e piora nas últimas 24 horas. Foi admitido em estado de insuficiência respiratória e choque cardiogênico com disfunção de múltiplos órgãos. O ecocardiograma mostrou fração de ejeção ventricular esquerda de 11%, grave hipocinesia difusa e pressão sistólica da artéria pulmonar de 50mmHg. Houve necessidade de suporte hemodinâmico com uso de dobutamina (20mcg/kg/minuto) e noradrenalina (1,7mcg/kg/minuto). Após 48 horas, o paciente não apresentou melhora hemodinâmica nem clínica, optando-se, então, pela implantação de membrana de oxigenação extracorpórea. Ocorreu melhora do ponto de vista hemodinâmico, da perfusão sistêmica, da função renal e hepática, porém, após 72 horas, não houve recuperação da função cardíaca. Optou-se, assim, pela transferência para outro hospital. O paciente foi transferido por transporte aéreo de Salvador (BA) para Recife (PE). Foi realizado transplante cardíaco com rápida recuperação da função hepática e renal, e boa função do enxerto. A histopatologia do coração explantado demonstrou miocardite crônica ativa e amastigotas de Trypanosoma cruzi. A prevalência global estimada de infecção por T. cruzi caiu de 18 milhões em 1991, quando a primeira iniciativa regional de controle teve início, para 5,7 milhões em 2010. A miocardite é uma doença inflamatória causada por condições infecciosas ou não infecciosas. As manifestações clínicas variam desde um quadro subclínico até insuficiência cardíaca e choque cardiogênico. Diversos relatos sugerem que o uso de membrana de oxigenação extracorpórea em pacientes com quadro grave e refratário de miocardite é uma opção como terapia ponte até transplante cardíaco, nos casos sem recuperação espontânea da função ventricular. Em uma consulta ambulatorial de acompanhamento realizada 6 meses após o transplante, o paciente encontrava-se bem e assintomático.


ABSTRACT A 17-year-old Brazilian male presented with progressive dyspnea for 15 days, worsening in the last 24 hours, and was admitted in respiratory failure and cardiogenic shock, with multiple organ dysfunctions. Echocardiography showed a left ventricle ejection fraction of 11%, severe diffuse hypokinesia, and a systolic pulmonary artery pressure of 50mmHg, resulting in the need for hemodynamic support with dobutamine (20mcg/kg/min) and noradrenaline (1.7mcg/kg/min). After 48 hours with no clinical or hemodynamic improvement, an extracorporeal membrane oxygenation was implanted. The patient presented with hemodynamic, systemic perfusion and renal and liver function improvements; however, his cardiac function did not recover after 72 hours, and he was transfer to another hospital. Air transport was conducted from Salvador to Recife in Brazil. A heart transplant was performed with rapid recovery of both liver and kidney functions, as well as good graft function. Histopathology of the explanted heart showed chronic active myocarditis and amastigotes of Trypanosoma cruzi. The estimated global prevalence of T. cruzi infections declined from 18 million in 1991, when the first regional control initiative began, to 5.7 million in 2010. Myocarditis is an inflammatory disease due to infectious or non-infectious conditions. Clinical manifestation is variable, ranging from subclinical presentation to refractory heart failure and cardiogenic shock. Several reports suggest that the use of extracorporeal membrane oxygenation in patients presenting with severe refractory myocarditis is a potential bridging therapy to heart transplant when there is no spontaneous recovery of ventricular function. In a 6-month follow-up outpatient consult, the patient presented well and was asymptomatic.
