RESUMEN

Takotsubo syndrome, was described in Japan in 1990, it is a stress cardiomyopathy, predominantly in women, usually postmenopausal. Cardiac hypokinesia occurs, with involvement of multiple coronary territories. In intensive care unit (ICU), it is considered underdiagnosed. Manifestations of severe dengue fever include cardiovascular involvement, mainly arrhythmias and systolic dysfunction. A case of a 72-year-old man is presented, who was hospitalized in ICU for dengue fever, with plateletopenia (15000 cells/mm3) and dehydration. After fluid management the patient reported respiratory discomfort, auscultating crackling rales. A pulmonary ultrasound was made where bilateral B lines were found with B7 pattern compatible with interstitial syndrome and pulmonary edema. Basal hyperkinesia, medial and apical hypokinesia with an image consistent with apical ballooning were observed in the transthoracic echocardiogram. The electrocardiogram showed complete right bundle branch block. Chagas serology was negative and quantitative troponin I was increased. In the context of severe dengue, a Takotsubo syndrome was diagnosed. The patient evolved favorably. After discharge, a normalization of the cardiac function was stated in ultrasound images. The case is of clinical importance due to the low association of these two diseases and the need to screen for cardiac involvement in severe dengue.

El síndrome de Takotsubo, fue descripto en Japón en 1990, se trata de una miocardiopatía por estrés, predominante en mujeres, generalmente postmenopáusicas. Se produce una hipoquinesia cardiaca, con compromiso de múltiples territorios coronarios. En las unidades de terapia intensiva (UTI), se considera subdiagnosticada. En las manifestaciones del dengue grave, se encuentra el compromiso cardiovascular, principalmente arritmias y disfunción sistólica. Se presenta el caso de un hombre de 72 años, internado en UTI por dengue, con plaquetopenia (15000 células/mm3) y deshidratación. Luego de la administración de fluidos refirió disconfort respiratorio, auscultándose estertores pulmonares. Se realizó ecografía pulmonar donde se apreció líneas B bilaterales con patrón B7 compatible con síndrome intersticial y edema pulmonar. En el ecocardiograma transtorácico se objetivó hiperquinesia basal, hipoquinesia medial y apical con imagen compatible con balonamiento apical. En el electrocardiograma se evidenció bloqueo completo de rama derecha. La serología para Chagas fue negativa y la troponina I cuantitativa se detectó aumentada. Se diagnosticó síndrome de Takotsubo en el contexto de dengue grave. El paciente evolucionó favorablemente. Posterior al alta, se constató normalización de la motilidad cardíaca, en las imágenes ecográficas. El caso es de importancia clínica por la baja asociación de las dos enfermedades y la necesidad de pesquisar el compromiso cardíaco en el dengue grave.

RESUMEN

Studies show that with the COVID-19 pandemic, the world's population went through multiple stress and anxiety factors, generating serious psychological problems, in addition, the virus also caused damage and physical stress to those contaminated. In this way, the intense emotional experiences and stressful effects on the body caused by SARS-CoV-2 are capable of triggering the excessive release of catecholamines in the body. Thus, the framework of Takotsubo Syndrome is characterized by myocardial dysfunction as a response of cardiac receptors to the spillage of such hormones in an unregulated way in the human body. The purinergic system plays a central role in this process, as it actively participates in actions responsible for the syndromic cascade, such as the stress generated by the cytokine storm triggered by the virus and the stimulation of deregulated catecholamine release. Therefore, further pharmacological studies on the role of purines in this pathology should be developed in order to avoid the evolution of the syndrome and to modulate its P1 and P2 receptors aiming at developing means of reversing or treating the Takotsubo Syndrome.

RESUMEN

INTRODUCTION: takotsubo syndrome (TTS) is a recently recognized entity that resembles an acute coronary syndrome. Its epidemiology has been studied in various populations around the world. The most frequent trigger is an emotional stressful event. OBJECTIVE: To describe the clinical characteristics of a series of cases with TTS. MATERIAL AND METHODS: A descriptive and retrospective study was carried out. The variables of age, gender, clinical characteristics, cardiovascular risk factors, triggering factors, biomarkers, electrocardiographic, echocardiographic, and angiographic findings in the clinical records of a group of cases of patients with TTS were evaluated. RESULTS: 19 cases of TTS were included. There were 16 women and 3 men, the average age was 62 ± 14 years; the main cardiovascular risk factor was sedentary lifestyle in 13 cases. The emotional trigger was present in most cases. The most frequent symptom was chest pain, eight cases presented data of shoCKP and heart failure. The most common variant by echocardiography was apical ballooning in 79%, as well as by ventriculography. The most common complication was cardiogenic shoCKP. CONCLUSIONS: The clinical characteristics of our population are like those previously described in the literature. TTS is a transient and reversible cardiomyopathy with a good prognosis.

INTRODUCCIÓN: El síndrome de takotsubo (STT) es una entidad de reciente reconocimiento que asemeja un síndrome coronario agudo. Su epidemiologia ha sido estudiada en diversas poblaciones del mundo. El desencadenante más frecuente es un evento estresante emocional. OBJETIVO: Describir las características clínicas de una serie de casos con STT. MATERIAL Y MÉTODOS: Se realizó un estudio descriptivo y retrospectivo. Se evaluaron las variables de edad, sexo, características clínicas, factores de riesgo cardiovascular, factores desencadenantes, biomarcadores, hallazgos electrocardiográficos, ecocardiográficos y angiográficos en los expedientes clínicos de un grupo de casos de pacientes con STT. RESULTADOS: Se incluyeron 19 casos de STT. Fueron 16 mujeres y 3 hombres, promedio de edad 62 ± 14 años; el principal factor de riesgo cardiovascular fue el sedentarismo, en 13 casos. El desencadenante emocional estuvo presente en la mayoría de los casos. El síntoma más frecuente fue el dolor torácico, ocho casos presentaron datos de choque e insuficiencia cardiaca. La variante más común por ecocardiograma fue el balonamiento apical en un 79%, al igual que por ventriculografía. La complicación más común fue choque cardiogénico. CONCLUSIONES: Las características clínicas de nuestra población son similares a las descritas previamente en la literatura. El STT es una miocardiopatía transitoria y reversible con buen pronóstico.

RESUMEN

Takotsubo syndrome is an acute heart disease usually triggered by significant emotional or physical stress, very occasionally described in association with natural disasters such as earthquakes. Clinically, it simulates an acute myocardial infarction with similar symptoms, laboratory tests, and electrocardiographic changes. Coronary angiography shows the absence of significant coronary disease. We report two women, aged 71 and 80 years, and who developed a Takotsubo syndrome after an earthquake. In both, the syndrome was diagnosed with cardiac magnetic resonance imaging.

RESUMEN

PURPOSE: Takotsubo syndrome is a reversible cardiomyopathy triggered by emotional or physical stressors. Although surgeries could be physical triggers, this has been scantily investigated. We aimed to describe the baseline characteristics, surgical/anesthesia-related triggering events, clinical presentation, and in-hospital outcomes of a cohort of patients diagnosed with perioperative Takotsubo syndrome. METHODS: In this retrospective study, we included all consecutive adult patients who were admitted to Hospital Italiano de Buenos Aires between 1 June 2008 and 30 November 2017 and diagnosed with Takotsubo syndrome according to the revised criteria of the European Society of Cardiology during hospitalization. RESULTS: We diagnosed 21 patients with perioperative Takotsubo syndrome out of 305,906 patients undergoing procedures with anesthesia care. The median (interquartile range [IQR]) patient age was 75 (55-82) yr, and 16 (76%) were women. The median (IQR) left ventricular ejection fraction was 35 (35-42)% at diagnosis and 55 (46-55)% at discharge. Fifteen patients (71%) required inotropic/vasopressor support; however, this is a controversial treatment considering the physiopathology of the syndrome. Severe complications such as unexplained syncope/cardiac arrest, cardiogenic shock, and ventricular thrombus formation occurred in seven (33%) patients, and two (10%) patients died. These results were compared with 31 patients who experienced non-perioperative Takotsubo syndrome during the same period of time. CONCLUSION: Perioperative Takotsubo syndrome is a reversible cardiomyopathy. Nevertheless, it seems to be associated with severe complications, the need for aggressive treatment, and non-negligible mortality.

RéSUMé: OBJECTIF: Le syndrome de Takotsubo est une cardiomyopathie réversible déclenchée par des facteurs de stress émotionnels ou physiques. Bien que les chirurgies puissent constituer des déclencheurs physiques, cela n'a été que peu étudié. Nous avons cherché à décrire les caractéristiques de base, les événements déclencheurs chirurgicaux / anesthésiques, la présentation clinique et les devenirs hospitaliers d'une cohorte de patients ayant reçu un diagnostic de syndrome périopératoire de Takotsubo. MéTHODE: Dans cette étude rétrospective, nous avons inclus tous les patients adultes consécutifs qui ont été admis à l'Hôpital Italiano de Buenos Aires entre le 1er juin 2008 et le 30 novembre 2017 et qui ont reçu un diagnostic de syndrome de Takotsubo selon les critères révisés de la Société européenne de cardiologie pendant leur hospitalisation. RéSULTATS: Nous avons diagnostiqué 21 patients atteints d'un syndrome de Takotsubo périopératoire sur 305 906 patients subissant des interventions nécessitant des soins d'anesthésie. L'âge médian des patients (écart interquartile [ÉIQ]) était de 75 ans (55-82 ans) et 16 (76 %) étaient des femmes. La médiane de la fraction d'éjection ventriculaire gauche (ÉIQ) était de 35 (35 à 42) % au moment du diagnostic et de 55 (46 à 55 ) % au congé. Quinze patients (71 %) ont eu besoin d'un soutien inotrope/vasopresseur; cependant, il s'agit d'un traitement controversé compte tenu de la physiopathologie du syndrome. Des complications graves telles qu'une syncope / un arrêt cardiaque inexpliqué, un choc cardiogénique et la formation de thrombus ventriculaire, sont survenues chez sept patients (33 %), et deux (10 %) patients sont décédés. Ces résultats ont été comparés à 31 patients ayant présenté un syndrome de Takotsubo non périopératoire au cours de la même période. CONCLUSION: Le syndrome de Takotsubo périopératoire est une cardiomyopathie réversible. Néanmoins, il semble être associé à des complications graves, à la nécessité d'un traitement agressif et à une mortalité non négligeable.

RESUMEN

El Síndrome de Takotsubo es una disfunción ventricular aguda reversible en ausencia de obstrucción coronaria. Una mujer de 85 años de edad con antecedentes de reemplazo valvular aórtico transcatéter, ingresó por dos semanas de dolor severo por una cadera desplazada por osteosíntesis fallida. Mientras se programaba para cirugía, se documentó hiponatremia severa secundaria a secreción inapropiada de hormona antidiurética. Súbitamente desarrolló edema agudo pulmonar. El ecocardiograma confirmó una válvula protésica funcional y aquinesia medial y apical de las paredes del ventrículo izquierdo. Recibió tratamiento con ventilación mecánica no invasiva, restricción de líquidos y diuréticos. La hiponatremia y la cardiomiopatía resolvieron.Takotsubo syndrome is a form of acute reversible left ventricular dysfunction in the absence of coronary obstruction. An 85-year-old lady with a medical history of transcatheter aortic valve replacement was readmitted complaining of 2 weeks of severe pain by a displaced hip and failed osteosynthesis. While she was scheduled for hip surgery, severe hyponatremia secondary to inappropriate antidiuretic hormone secretion was documented, and sudden-onset pulmonary edema ensued. Echocardiography confirmed normally functioning aortic prosthetic valve and classical features of Takotsubo. She was treated with non-invasive mechanical ventilation, water restriction, and diuretics. Hyponatremia and the cardiomyopathy resolved and the patient recovered completely.

RESUMEN

This article aims to make reference to some recent mourning aspects considered risk factors for cardiovascular disease, specifically the Takotsubo cardiomyopathy. The objective was to describe the stress from the death of a loved one combining it to the possibility of occurrence of Takotsubo cardiomyopathy through the perception of a traumatic event by the cortex, which triggers the subcortical brain circuit affecting the endocrine response. Given the growing acknowledgement of this cardiomyopathy, it is possible to contextualize the nutritional behaviours and decisions surrounding it, whose benefits must exceed the condition of temporary cardiac dysfunction and extend to food choices that have some influence in the limbic system. It is a descriptive analysis that aims to problematize the theme into reflections based on this experience, considering the foundation with the science of nutrition.

RESUMO INTRODUÇÃO: Este artigo busca fazer referência a alguns aspectos do luto recente considerados fatores de risco para a doença cardiovascular, específicamente a cardiomiopatia de Takotsubo. Objetivou-se descrever o estresse proveniente da morte do ente querido aliando-o à possibilidade de ocorrência da cardiomiopatia de Takotsubo, mediante a percepção de um evento traumático pelo córtex que aciona o circuito cerebral subcortical tendo repercussões na resposta endócrina. Dado o crescente reconhecimento dessa cardiomiopatia, torna-se viável contextualizar as condutas nutricionais e as decisões que as norteiam, cujos benefícios devem ultrapassar a condição de disfunção cardíaca temporária e se estender às escolhas alimentares que exercem alguma influência no sistema límbico. Trata-se de uma análise descritiva que objetiva problematizar a temática em reflexões pautadas nessa vivência, considerando o alicerce com a ciência da nutrição.

RESUMEN

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.

RESUMEN

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.

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.
