Resumo Fundamento O choque cardiogênico (CC) refratário está associado com altas taxas de mortalidade, e o uso de oxigenação por membrana extracorpórea venoarterial (VA-ECMO, do inglês venoarterial extracorporeal membrane oxygenation) como uma opção terapêutica tem gerado discussões. Nesse sentido, sua custo-efetividade, principalmente em países de baixa e média renda como o Brasil, continua incerto.Objetivos: Conduzir uma análise de custo-efetividade na perspectiva do Sistema Único de Saúde (SUS) para avaliar a custo-efetividade de VA-ECMO combinado com o tratamento padrão em comparação ao tratamento padrão isolado em pacientes adultos com CC refratário. Métodos Acompanhamos uma coorte de pacientes com CC refratário tratados com VA-ECMO em centros de assistência terciária do sul brasileiro. Coletamos dados de desfechos e custos hospitalares. Realizamos uma revisão sistemática para complementar nossos dados e usamos o modelo de Markov para estimar a razão de custo-efetividade incremental (RCEI) por ano de vida ajustado pela qualidade (QALY) e por ano de vida ganho. Resultados Na análise do caso-base, a VA-ECMO gerou uma RCEI de Int$ 37 491 por QALY. Análises de sensibilidade identificaram o custo de internação, o risco relativo de sobrevida, e a sobrevida do grupo submetido à VA-ECMO como principais variáveis influenciando os resultados. A análise de sensibilidade probabilística mostrou um benefício do uso de VA-ECMO, com uma probabilidade de 78% de custo-efetividade no limiar recomendado de disposição a pagar. Conclusões Nosso estudo sugere que, dentro do SUS, VA-ECMO pode ser uma terapia custo-efetiva para o CC refratário. Contudo, a escassez de dados sobre a eficácia e de ensaios clínicos recentes que abordem seus benefícios em subgrupos específicos de pacientes destaca a necessidade de mais pesquisas. Ensaios clínicos rigorosos, incluindo perfis diversos de pacientes, são essenciais para confirmar a custo-efetividade com uso de VA-ECMO e assegurar acesso igualitário a intervenções médicas avançadas dentro dos sistemas de saúde, especialmente em países com desigualdades socioeconômicas como o Brasil.

Introduction: initially, it was believed that, in pediatrics, SARS-CoV-2 infection would be mild or asymptomatic. However, it is now known that children can present a very symptomatic condition, such as Pediatric Multisystem Inflammatory Syndrome (SIM-P). Objective: to report the case of a seven-year-old child with SIM-P post-infection with SARS-CoV-2 progressing to cardiogenic shock. Method: qualitative descriptive case report research. Data collection was done from authorized copies of the medical records made available by the child's guardian, made official by signing the consent terms, TALE/TCLE. Case Report: girl, seven years old, presents to emergency care presenting persistent fever, vomiting, prostration and report of recent contact with an individual with flu-like symptoms. Upon admission, fever, diffuse and intense pain on abdominal palpation, coated tongue, fissures on the lip and hyperemic tonsils. This condition, associated with laboratory tests (increase in inflammatory markers, coagulopathy, myocardial injury and contact with SARS-CoV-2), defined a diagnosis of SIM-P, according to WHO criteria. A place in the Pediatric ICU was requested and Human Immunoglobulin was prescribed. Upon admission, it progressed to cardiogenic shock, using vasoactive drugs. After eight days in hospital, her condition improved. Conclusion: despite being multisymptomatic, gastrointestinal symptoms predominate in SIM-P. However, cardiovascular involvement is concerned due to the risk of unfavorable outcomes, requiring early recognition and treatment. [ABSTRACT FROM AUTHOR]

Resumo O presente relato de caso descreve o programa de exercícios aplicado a um paciente do sexo masculino, de 54 anos, internado com choque cardiogênico, aguardando transplante cardíaco e assistido por balão intra-aórtico, um dispositivo de suporte circulatório mecânico temporário. O dispositivo de suporte circulatório mecânico temporário, um balão intra-aórtico, foi colocado na artéria subclávia esquerda, possibilitando o protocolo de exercícios. Antes e após um protocolo de exercícios, foram obtidos dados a partir de cateter de Swan-Ganz, amostra de sangue, peptídeo natriurético cerebral (NT-proBNP), proteína C reativa de alta sensibilidade (PCR-as), teste de caminhada de seis minutos (TC6min) e medição da saturação venosa de oxigênio (SvO2). O protocolo de treinamento físico envolveu a utilização de um cicloergômetro adaptado ao leito, sem carga, uma vez ao dia, por no máximo 30 minutos, até o limite da tolerância. Não foram observados eventos adversos tampouco relacionados ao deslocamento do balão intra-aórtico durante o protocolo de exercícios. O programa de exercícios resultou em maior SvO2 com aumento do TC6min e menores escores de dispneia de Borg (312 metros vs. 488 metros e cinco pontos vs. três pontos, respectivamente). Após completar o protocolo de exercícios de dez dias, o paciente foi submetido a uma cirurgia de transplante cardíaco sem complicações e recuperação total na UTI. O presente estudo demonstrou que o exercício é uma opção viável para pacientes com choque cardiogênico em uso de balão intra-aórtico e que é bem tolerado, além de não haver relatos de eventos adversos.

Resumo Fundamento A infecção concomitante por coronavírus 2019 (COVID-19) e o infarto do miocárdio com supradesnivelamento do segmento ST (IAMCSST) estão associados ao aumento de desfechos adversos hospitalares. Objetivos O estudo teve como objetivo avaliar as diferenças angiográficas, de procedimentos, laboratoriais e prognósticas em pacientes positivos e negativos para COVID-19 com IAMCSST submetidos à intervenção coronária percutânea primária (ICP). Métodos Realizamos um estudo observacional retrospectivo e unicêntrico entre novembro de 2020 e agosto de 2022 em um hospital de nível terciário. De acordo com o seu estado, os pacientes foram divididos em dois grupos (positivo ou negativo para COVID-19). Todos os pacientes foram internados por IAMCSST confirmado e foram tratados com ICP primária. Os desfechos hospitalares e angiográficos foram comparados entre os dois grupos. P-valores bilaterais

The right ventricle is susceptible to changes in preload, afterload, and contractility. The answer is its dilation with dysfunction/ acute failure; filling is limited to the left ventricle and cardiac output. Systemic venous congestion is retrograde to the right heart, it is involved in the genesis of cardiogenic shock due to right ventricle involvement. This form of shock is less well known than that which occurs due to left ventricular failure, therefore, treatment may differ. Once the primary treatment has been carried out, since no response is obtained, supportive treatment aimed at ventricular pathophysiology will be the next option. It is suggested to evaluate the preload for the reasoned indication of liquids, diuretics or even ultrafiltration. Restore or maintain heart rate and sinus rhythm, treat symptomatic bradycardia, arrhythmias that make patients unstable, use of temporary pacing or cardioversion procedures. Improving contractility and vasomotility, using vasopressors and inotropes, alone or in combination, the objective will be to improve right coronary perfusion pressure. Balance the effect of drugs and maneuvers on preload and/or afterload, such as mechanical ventilation, atrial septostomy and pulmonary vasodilators. And the increasing utility of mechanical support of the circulation that has become a useful tool to preserve/restore right heart function. [ABSTRACT FROM AUTHOR]

Introduction and objectives: Cardiogenic shock (CS) complicates 5–10% of cases of myocardial infarction (MI). Whether glycoprotein IIb/IIIa inhibitors (GPIs) are beneficial in these patients is controversial. Our aim is to assess the prognostic impact of GPI use on in-hospital mortality and outcomes in patients with MI and CS undergoing percutaneous coronary intervention (PCI). Methods: Between October 2010 and December 2019, 27 578 acute coronary syndrome (ACS) patients were included in the multicenter Portuguese Registry of Acute Coronary Syndromes. Of these, 357 with an MI complicated by CS were included in the analysis and grouped based on whether they received GPI therapy (with GPI, n=107 and without GPI, n=250). The primary endpoint was in-hospital mortality. Secondary endpoints included successful PCI and in-hospital reinfarction and major bleeding. Results: Demographics and cardiovascular risk factors did not differ between groups. ST-elevation MI patients were more likely to receive GPIs (95% vs. 83%, p=0.002). In-hospital mortality was similar between groups (OR 1.80, 95% CI 0.96–3.37). Only age and the use of inotropes or intra-aortic balloon pump were predictors of mortality. Also, no differences between groups were noted for successful PCI (OR 0.33, 95% CI 0.62–4.06), reinfarction (OR 0.77, 95% CI 0.15–3.90), or major bleeding (OR 1.68, 95% CI 0.75–3.74). Conclusion: The use of GPIs in the context of MI with CS did not significantly impact in-hospital outcomes. Resumo: Introdução e objetivos: O choque cardiogénico (CC) complica 5-10% dos enfartes agudos do miocárdio (EAM). O benefício do uso de inibidores da glicoproteína IIb/IIIa (GPI) nestes doentes é controverso. O nosso objetivo é avaliar o impacto prognóstico do uso de GPI nos outcomes intra-hospitalares em doentes com EAM e CC submetidos a intervenção coronária percutânea (ICP). Métodos: Entre outubro de 2010 e dezembro de 2019, 27 578 doentes com síndrome coronária aguda (SCA) foram incluídos no Registo Português de SCA. Destes, 357 com EAM complicado por CC foram incluídos. Dois grupos foram criados, baseados no facto de terem recebido terapêutica com GPI (GPI, N=107 e sem tratamento com GPI, N=250). O endpoint primário foi a mortalidade intra-hospitalar. Endpoints secundários incluíram sucesso de ICP, re-enfarte e hemorragia major. Resultados: As características demográficas e os fatores de risco cardiovasculares não diferiram entre grupos. Doentes com EAM com supra-ST receberam mais terapêutica com GPI (95% versus 83%, P=0,002). A mortalidade intra-hospitalar foi similar entre grupos (OR 1,80, 95% CI 0,96-3,37, P=0,068). Apenas a idade, uso de inotrópicos ou balão intra-aórtico foram preditores de mortalidade. Não houve diferenças para sucesso de ICP (OR 0,33, 95% CI 0,62-4,06); re-enfarte (OR 0,77, 95% CI 0,15-3,90) ou hemorragia major (OR 1,68, 95% CI 0,75-3,74). Conclusão: O uso de GPI no contexto de EAM com CC não teve impacto significativo nos outcomes intra-hospitalares.

The Swan-Ganz (SG) catheter is an indispensable tool for invasive hemodynamic monitoring but is underused due to controversy for misunderstandings after several confounding studies. The Mexican College of Interventional Cardiology and Endovascular Therapy (COMEOTE) invited a select group of international specialists in interventional cardiology, critical cardiology care, and general intensive care for a consensus statement on SG catheter use, endorsed by COMEOTE and the Mexican College of Critical Care (COMMEC). The consensus recommends the SG as a diagnostic tool in cardiogenic shock from any etiology and at any class and level, involving one ventricle or both; during worsening heart failure/hemodynamic instability, despite adequate treatment; for differential diagnosis during failed treatment for respiratory distress, hypotension, and or progressive renal failure; for simultaneous monitoring of the pulmonary artery and right atrial pressures during severe right heart-related shock. The consensus encourages centers with low SG utilization to include and master its hemodynamic monitoring benefits. [ABSTRACT FROM AUTHOR]

Introduction and Objectives: The use of mechanical circulatory support is increasing in cases of cardiogenic shock (CS) and high-risk percutaneous coronary intervention (HR-PCI). The Impella® is a percutaneous ventricular assist device that unloads the left ventricle by ejecting blood to the ascending aorta. We report our center's experience with the use of the Impella® device in these two clinical settings. Methods: We performed a single-center retrospective study including all consecutive patients implanted with the Impella® between 2007 and 2019 for CS treatment or prophylactic support of HR-PCI. Data on clinical and safety endpoints were collected and analyzed. Results: Twenty-two patients were included: 12 were treated for CS and 10 underwent an HR-PCI procedure. In the CS-treated population, the main cause of CS was acute myocardial infarction (five patients); hemolysis was the most frequent device-related complication (63.7%). In-hospital, cumulative 30-day and one-year mortality were 58.3%, 66.6% and 83.3%, respectively. In the HR-PCI group, all patients had multivessel disease (mean baseline SYNTAX I score: 44.1±13.7). In-hospital, 30-day and one-year mortality were 10.0%, 10.0% and 20.0%, respectively. There were no device- or procedure-related deaths in either group. Conclusion: The short- and long-term results of Impella®-supported HR-PCI were comparable to those in the literature. In the CS group, in-hospital and short-term outcomes were poor, with high mortality and non-negligible complication rates. Resumo: Introdução e objetivos: O uso de suporte mecânico no choque cardiogénico (CS) e intervenção coronária percutânea de alto risco (HR-PCI) tem aumentado. O Impella® é um sistema de suporte ventricular percutâneo que ejeta sangue do ventrículo esquerdo para a aorta ascendente. Reportamos a experiência do nosso centro com o Impella® nestes dois cenários clínicos. Métodos: Estudo retrospetivo unicêntrico incluindo todos os doentes consecutivos submetidos a implantação de Impella® entre 2007 e 2019, para tratamento de CS ou suporte profilático para HR-PCI. Dados sobre endpoints clínicos e de segurança foram analisados. Resultados: Foram incluídos 22 doentes: 12 tratados por CS e 10 submetidos a HR-PCI. Na população de CS, a principal causa de choque foi o enfarte agudo do miocárdio (5 doentes); a hemólise foi a complicação relacionada com o dispositivo mais frequente (63,7%); a mortalidade intra-hospitalar, a 30 dias e um ano, foi, respetivamente, 58,3%, 66,6% e 83,3%. No grupo da HR-PCI, todos os doentes apresentavam doença multivaso (SYNTAX I score médio: 44,1±13,7); a mortalidade intra-hospitalar, a 30 dias e um ano, foi, respetivamente, 10,0%, 10,0% e 20,0%. Não houve mortes relacionadas com o dispositivo ou procedimento em ambos os grupos. Conclusão: Os resultados em curto e longo prazo da HR-PCI protegida por Impella® foram comparáveis aos da literatura disponível. No grupo de CS, os resultados intra-hospitalares e em curto prazo foram desanimadores, com elevada mortalidade e taxas de complicações apreciáveis.

Acute severe mitral regurgitation (MR) because of secondary left ventricular impaired regional contractility can present with severe acute heart failure, associated with a high risk for rapid decompensation, pulmonary edema and cardiogenic shock. Frequently, in these highly unstable patients, surgical risk can be prohibitive. Evidence for percutaneous repair of acute MR is scarce, but a few case series show that this approach could be safe and effective for bailing out hemodynamically unstable patients.We report a case of an 84-year-old man with acute ischemic severe MR post-acute myocardial infarction (MI), who remained hemodynamically unstable despite coronary revascularization, positive pressure non-invasive ventilation, vasodilator therapy and intra-aortic balloon pump (IABP) support. In heart team discussions, he was considered a high risk surgical candidate. We decided on rescue off-label percutaneous mitral valve repair with a MitraClip device (Abbott Vascular, Santa Clara, California), with good clinical result, allowing weaning from the supports and discharge seven days after the procedure. At one-year follow-up, the patient maintained a MV repair results and had a good functional status. In unstable patients with acute ischemic MR, percutaneous MV repair could be a rescue therapeutic option to consider, allowing hemodynamic compensation with potential persistent MR improvement up to one-year follow-up. Resumo: A insuficiência mitral (IM) aguda grave causada por alterações isquémicas secundárias loco-regionais do ventrículo esquerdo associa-se a elevado risco de descompensação hemodinâmica com edema pulmonar e choque cardiogénico. Frequentemente, nestes doentes instáveis, o risco cirúrgico pode ser proibitivo. É escassa a evidência existente relativamente à abordagem percutânea da IM aguda neste contexto, existindo apenas algumas séries de casos que parecem mostrar segurança e eficácia no resgate de doentes instáveis.Reportamos o caso de um doente de 84 anos, género masculino, com IM aguda grave isquémica após enfarte agudo do miocárdio, que permaneceu com instabilidade hemodinâmica apesar de revascularização coronária, ventilação não invasiva com pressão positiva, terapêutica com vasodilatadores e suporte de balão intra-aórtico. Após discussão em reunião de Heart Team, o doente foi considerado de elevado risco cirúrgico, tendo sido orientado para tratamento percutâneo da válvula mitral com dispositivo MitraClip. O procedimento decorreu sem intercorrências imediatas, permitindo redução com critérios de sucesso da IM. A melhoria do perfil hemodinâmico com a correção percutânea da IM permitiu rápido desmame da terapêutica de suporte em curso, com evolução clínica favorável subsequente e alta ao sétimo dia após procedimento. No seguimento clínico e ecocardiográfico a um ano verificou-se a persistência do resultado do tratamento percutâneo da IM e o doente apresentava boa capacidade funcional.Em pacientes instáveis com MR isquémica aguda, a reparação percutânea da VM poderia ser uma opção terapêutica de salvamento a considerar, permitindo uma compensação hemodinâmica com potencial melhoria persistente da MR até 1 ano de seguimento.

Introduction and Objectives: Cardiogenic shock (CS) has long been considered a contraindication for the use of non-invasive ventilation (NIV). The main objective of this study was to analyze the effectiveness, measured as NIV success, in patients with respiratory failure due to CS. As secondary objective, we studied risk factors for NIV failure and compared the outcome of patients treated with NIV versus invasive mechanical ventilation (IMV)., Methods: Retrospective study on a prospective database, over a period of 25 years, of all consecutively patients admitted to an intensive care unit, with a diagnosis of CS and treated with NIV. A comparison was made between patients on NIV and patients on IMV using propensity score matching analysis., Results: Three hundred patients were included, mean age 73.8 years, mean SAPS II 49. The main cause of CS was acute myocardial infarction (AMI): 164 (54.7%). NIV failure occurred in 153 (51%) cases. Independent factors for NIV failure included D/E stages of CS, AMI, NIV related complications, and being transferred from the ward. In the propensity analysis, hospital mortality (OR 1.69, 95% CI 1.09-2.63) and 1 year mortality (OR 1.61, 95% CI 1.04-2.51) was higher in IMV. Mortality was lower with NIV (vs. EIT-IMV) in C stage (10.1% vs. 32.9%; p<0.001) but did not differ in D stage or E stage., Conclusions: NIV seems to be relatively effective and safe in the treatment of early-stage CS., (Copyright © 2023 Sociedade Portuguesa de Cardiologia.

Introduction and Objectives: Acute total occlusion of the unprotected left main coronary artery (LMCA) is a dramatic event. There are limited data regarding this population. We aimed to describe the clinical presentation and outcomes of patients and to determine predictors of in-hospital mortality., Methods: This retrospective study included patients presenting with acute (<12 h) myocardial infarction due to total occlusion of the LMCA (TIMI flow 0) between January 2008 and December 2020 in three tertiary hospitals., Results: During this period, 11036 emergent coronary angiographies were performed, 59 (0.5%) of which revealed acute total occlusion of the LMCA. Patients' mean age was 61.2 (SD±12.2) years and 73% were male. No patients had left dominance. At presentation, 73% were in cardiogenic shock, aborted cardiac arrest occurred in 27% and 97% underwent myocardial revascularization. Primary percutaneous coronary intervention was performed in 90% of cases and angiographic success was achieved in 56% of procedures, while 7% of patients underwent surgical revascularization. In-hospital mortality was 58%. Among survivors, 92% and 67% were alive after one and five years, respectively. After multivariate analysis, only cardiogenic shock and angiographic success were independent predictors of in-hospital mortality. Use of mechanical circulatory support and presence of well-developed collateral circulation were not predictive of short-term prognosis., Conclusion: Acute total occlusion of the LMCA is associated with a dismal prognosis. Cardiogenic shock and angiographic success play a major role in predicting the prognosis of these patients. The effect of mechanical circulatory support on patient prognosis remains to be determined., (Copyright © 2023. Publicado por Elsevier España, S.L.U.)

Aims: To assess the clinical profile and factors associated with 30-day mortality in patients with acute heart failure (AHF) admitted to the intensive care unit (ICU)., Design: Prospective, multicentre cohort study., Scope: Thirty-two Spanish ICUs., Patients: Adult patients admitted to the ICU between April and June 2017., Intervention: Patients were classified into three groups according to AHF status: without AHF (no AHF); AHF as the primary reason for ICU admission (primary AHF); and AHF developed during the ICU stay (secondary AHF)., Main Variables of Interest: Incidence of AHF and 30-day mortality., Results: A total of 4330 patients were included. Of these, 627 patients (14.5%) had primary (n=319; 7.4%) or secondary (n=308; 7.1%) AHF. Among the main precipitating factors, fluid overload was more common in the secondary AHF group than in the primary group (12.9% vs 23.4%, p<0.001). Patients with AHF had a higher risk of 30-day mortality than those without AHF (OR 2.45; 95% CI: 1.93-3.11). APACHE II, cardiogenic shock, left ventricular ejection fraction, early inotropic therapy, and diagnostic delay were independently associated with 30-day mortality in AHF patients. Diagnostic delay was associated with a significant increase in 30-day mortality in the secondary group (OR 6.82; 95% CI 3.31-14.04)., Conclusions: The incidence of primary and secondary AHF was similar in this cohort of ICU patients. The risk of developing AHF in ICU patients can be reduced by avoiding modifiable precipitating factors, particularly fluid overload. Diagnostic delay was associated with significantly higher mortality rates in patients with secondary AHF., (Copyright © 2022 Elsevier España, S.L.U. and SEMICYUC. All rights reserved.)
