A Case of Takotsubo Cardiomyopathy after Elective Mitral Valve Repair / 日本心臓血管外科学会雑誌

We describe Takotsubo syndrome, which developed after elective mitral valve repair and tricuspid annuloplasty in a 76-year-old woman. A preoperative echocardiogram confirmed severe mitral regurgitation due to posterior leaflet prolapse, moderate tricuspid regurgitation, and normal left ventricular function. Mitral valve repair and tricuspid annuloplasty were performed. After uneventful weaning off cardiopulmonary bypass, intraoperative transesophageal echocardiography revealed adequate mitral leaflet function and normal left ventricular contractions. After being transferred to the intensive care unit, the patient's hemodynamic parameters progressively deteriorated. Transthoracic echocardiography showed akinesis and ballooning of the apex and hyperkinesis of the base, and the ejection fraction was 20% on postoperative day 1. The serum aminotransferase and CPK-MB levels increased on postoperative day 2. The left ventricular function did not improve despite supportive therapy with vasopressors. She developed cardiogenic cerebral infarction due to obstruction of the right middle cerebral artery on postoperative day 8. Endovascular thrombectomy was performed within 2 h of the onset of cerebral infarction. Thereafter, the patient gradually recovered and was discharged without any sequelae on postoperative day 31. The ejection fraction was 65% with normal left ventricular motion at discharge. An electrocardiogram revealed a deep negative T wave in II, III, aVF, and V3-V6. After 2 months, the electrocardiogram findings were normalized. Coronary lesions were not observed on pre- or postoperative coronary angiographies; therefore, we diagnosed Takotsubo cardiomyopathy after mitral valve repair. Takotsubo cardiomyopathy should be considered as a possible complication of cardiac surgery, especially after mitral valve surgery.

Síndrome de Takotsubo: Actualización 2022 / Takotsubo Syndrome: 2022 Update

El síndrome de Takotsubo es una enfermedad cardíaca aguda que se presenta con un cuadro clínico similar al de un síndrome coronario agudo y se caracteriza por alteraciones segmentarias de la contracción ventricular transitorias, con un árbol coronario normal o con lesiones coronarias no significativas que las expliquen. Se observa, generalmente, en mujeres posmenopáusicas; el cual se desencadena principalmente por un estrés emocional o físico severo y su diagnóstico es un desafío clínico. Este artículo entrega una revisión de los factores desencadenantes y de riesgo y las principales hipótesis causales de esta enfermedad. Proporciona, además, una revisión actualizada de las pruebas diagnósticas que deben ser realizadas, el algoritmo para su diagnóstico, las complicaciones y el manejo terapéutico actual.

Takotsubo syndrome is an acute cardiomyopathy with a clinical presentation resembling an acute coronary syndrome. It is characterized by transient segmental ventricular dysfunction with a normal underlying coronary tree or coronary lesions that cannot explain the ventricular dysfunction. It is usually seen in postmenopausal women, triggered by severe emotional or physical stress, and is clinically challenging to diagnose. This article provides an exhaustive review of the risk factors, triggers, and main hypotheses to explain this disease. In addition, it provides an updated review of the diagnostic tests that must be performed, the diagnostic algorithms, their complications, and current therapeutic management.

Síndrome de tako-tsubo en una adolescente. Presentación de caso

El síndrome de tako-tsubo es una miocardiopatía aguda por estrés, caracterizada por una anormalidad regional del movimiento de la pared del ventrículo izquierdo, con un patrón circunferencial peculiar que resulta en un abultamiento notorio del ventrículo izquierdo durante la sístole. En Cuba, el síndrome de tako-tsubo ha sido publicado en pacientes adultos, pero se considera una entidad rara en niños, razón por la cual se decidió hacer este reporte. Se presenta el caso de una adolescente de 16 años, con antecedentes de haber dado a luz hacía 44 días al momento del ingreso, que fue recibida en el Servicio de Emergencias en estado grave, con disnea, dolor precordial y manifestaciones de choque, por lo que fue derivada inmediatamente a la Unidad de Cuidados Intensivos Pediátricos. Los antecedentes de haber tenido un factor desencadenante de estrés como el parto por cesárea, el electrocardiograma con signos de isquemia miocárdica y el ecocardiograma típico, con discinesia de segmentos apicales del ventrículo izquierdo, permitieron hacer el diagnóstico de síndrome de tako-tsubo y dirigir el tratamiento en ese sentido. Este síndrome es infrecuente en la edad pediátrica, por tanto, puede presentarse como una forma grave y no ser reconocido, trayendo implicaciones pronósticas.

Takotsubo syndrome is an acute stress cardiomyopathy, characterized by a regional abnormality of left ventricular wall motion, with a peculiar circumferential pattern that results in marked left ventricular bulging during systole. In Cuba, takotsubo syndrome has been published in adult patients, but it is considered a rare entity in children, so it was decided to make this report. The case of a 16-years-old adolescent, with a history of having given birth 44 days before at the time of admission, who was received at the Emergency Department in serious condition, with dyspnea, precordial pain, and manifestations of shock, for what she was immediately referred to the Pediatric Intensive Care Unit it is presented. The history of having had a stress trigger such as delivery by cesarean section, the electrocardiogram with signs of myocardial ischemia, and the typical echocardiogram, with dyskinesia of the apical segments of the left ventricle, allowed the diagnosis of takotsubo syndrome and direct treatment in that sense. This syndrome is rare in the pediatric age, therefore, it can present as a severe form and not be recognized, bringing prognostic implications.

Takotsubo cardiomyopathy: a rare neuro-cardiological entity with its challenges

Takotsubo cardiomyopathy (TCM) is a type of neuro cardiological disorder that evince as acute but reversible heart failure. On the whole, it occurs by stress-related cardiomyopathy which illustrates the heart-brain connection. It was first discovered in 1990, by a Japanese cardiovascular specialist. That's the beginning of this heart disease in gaining worldwide acceptance as an independent disease entity. TCM is entirely different from acute myocardial infarction as usually occurs in postmenopausal elderly women due to emotional or physical stress. It is characterized by transient hypokinesis of the left ventricular apex. However, there are complications too that need to be addressed. Some reports of serious TCM include hypotension, thrombosis involving LV apex, heart failure, and ventricular rupture. It is also suggested that coronary spasms, myocarditis, and coronary microvascular dysfunction might contribute to the pathogenesis of TCM. But in total, its pathophysiology is unclear. In this review article, we review the pathogenesis and etiology of this rare complex disorder along with its clinical features, findings, challenges in diagnosis, and a comprehensive discussion on the same.

Clinical features of pregnant associated Takotsubo cardiomyopathy: a literature review of 60 cases / 中华围产医学杂志

Objective:To investigate the clinical features of pregnant associated Takotsubo cardiomyopathy (PTCM).Methods:We reviewed reported PTCM cases published from January 2007 to June 2022 using the keywords "Tako-tsubo cardiomyopathy""Takotsubo cardiomyopathy" "stress cardiomyopathy" AND "parturition" "pregnancy" "cesarean delivery" "postpartum" "peripartum" "eclampsia" "abortion" in Pubmed and Web of Science databases and the corresponding Chinese words in Wanfang and Chinese Medical Journal Network. Age, obstetric history, mode of delivery, mode of anesthesia, etiological factors, clinical manifestations, treatment, and prognosis of PTCM were recorded. Descriptive statistical analysis was adopted.Results:A total of 55 articles were included, covering 60 patients with PTCM. (1) Age and time of onset: The age of onset was (32.4±6.0) years old. PTCM occurred most frequently during labor [42% (25/60)] and within one day postpartum [32% (19/60)] and during the gestational period [13%(8/60), 33.0 weeks (24.5-37.7 weeks)]. (2) Delivery-related factors: There were 38% (16/42) primiparas and 60% (25/42) multiparas. Among them, 67% (38/57) and 18% (10/57) were delivered by cesarean section and vaginal delivery, respectively. PCTM often lacks obvious triggers [40% (24/60)], with the most common inducing factor being pregnancy-related diseases [27% (16/60)]. (3) Clinical features: The initial symptoms of PTCM were dyspnea [44% (26/59)], followed by chest pain accompanied by dyspnea [17% (10/59)]. The most common subtype of PTCM was the apical type [45% (26/58)], followed by the basal type [24% (14/58)], while the biventricular type was the least common [3% (2/58)] in the PTCM classification. The left ventricular ejection fraction was (31.6±12.1) % at the onset of PTCM, which recovered to (58.2±7.6) % at discharge. PCTM was often complicated by pulmonary edema [67% (40/60)] and cardiogenic shock [55% (33/60)]. (4) Treatment and prognosis: Patients with PCTM usually require noninvasive or invasive ventilator-assisted ventilation [40% (23/58)]. One pregnant woman and five neonates died, while the remaining patients recovered well.Conclusions:PTCM should be considered in differential diagnosis of patients experiencing dyspnea and chest pain during labor and pregnancy. PTCM patients are younger and have more pulmonary edema and cardiogenic shock. Mechanical ventilation is often required, but the prognosis is favorable.

Recurrent takotsubo syndrome: case report and literature review

Introduction: Takotsubo syndrome is a cardiomyopathy that can lead to severe myocardial involvement. It is characterized by the presence of signs and symptoms suggestive of ventricular dysfunction associated with an adrenergic discharge during a stressful event. This case report presents a literature review, as well as a comparison with other similar cases. Case presentation. A 56-year-old female with a previous episode of Takotsubo was admitted to the emergency department due to symptoms of acute coronary syndrome and a history of Takotsubo syndrome. Her electrocardiogram showed T-wave inversion in leads V1-V4 and a raise in troponins. Percutaneous coronary angiography revealed no coronary lesions, and an echocardiogram revealed segmental alterations compatible with Takotsubo syndrome, requiring medical therapy with beta-blockers and angiotensin-converting enzyme (ACE) inhibitors, with subsequent improvement in ventricular function. Conclusions. Recurrence in Takotsubo cardiomyopathy is a rare complication that should be suspected. The risk factors associated with recurrence are not known. Although therapy with ACE inhibitors and beta-blockers seems to have an impact on the recovery of ventricular function in patients with this condition, further studies are necessary to establish the best pharmacological treatment.

Introducción. La miocardiopatía de Takotsubo (MT) es una afección cardiaca que puede generar compromiso miocárdico severo y se caracteriza por la presencia de signos y síntomas sugestivos de disfunción ventricular que se asocian a una descarga adrenérgica durante un evento estresor. En este reporte de caso se realizó una revisión de la literatura y se hizo una comparación con otros casos similares al presentado. Presentación del caso. Mujer de 56 años, quien asistió al servicio de urgencias por síntomas sugestivos de un síndrome coronario agudo. A la paciente, que tenía antecedente de MT, se le realizó un electrocardiograma que mostró inversión de la onda T en las derivaciones V1-V4 y elevación de troponinas, una angiografía coronaria que evidenció arterias epicárdicas sin lesiones y un ecocardiograma que reveló alteraciones segmentarias compatibles con MT, por lo que se estableció manejo con betabloqueadores e inhibidores de la enzima convertidora de angiotensina (IECA), con lo cual se logró mejoría de la función ventricular. Conclusiones. La MT es una afección poco frecuente de la cual no se conocen los factores de riesgo asociados a su recurrencia. Aunque la terapia con IECA y betabloqueadores parece tener un impacto en la recuperación de la función ventricular en pacientes con esta condición, se requieren estudios adicionales para establecer el mejor manejo farmacológico.

Brain functional connectivity in takotsubo cardiomyopathy patients. A systematic review of magnetic resonance imaging studies / Conectividad funcional cerebral en pacientes con miocardiopatía de takotsubo: Revisión sistemática de estudios de imagen por resonancia magnética

Abstract Background: Functional neuroimaging studies may aid to our understanding of the pathophysiology of the takotsubo cardiomyopathy. Objective: The aim of the study was to review the available evidence of brain functional connectivity in takotsubo cardiomyopathy patients. Methods: This was a systematic review. We searched MEDLINE, LILACS, Ovid (Cochrane), Scopus, and Science Direct for studies conducting functional magnetic resonance imaging (fMRI) in takotsubo patients. After reviewing title/abstract and full text, we selected relevant studies, extracted methodological characteristics, and their main findings, and assessed their risk of bias with the Newcastle-Ottawa scale. We present a narrative review. Results: We included five case-control studies from 600 registries. The risk of bias was low; comparability was the main issue. Resting-state fMRI findings suggest significant differences for the hippocampus, the Insula, the amygdala, and the para-hippocampal gyrus. Task fMRI findings suggest significant differences for the Insula, the superior occipital gyrus, and the amygdala. Studies were heterogeneous about the laterality and directionality of these differences. Conclusion: Brain connectivity alterations involving elements relevant for autonomic control like the Insula and the Amygdala provide evidence in favor of the role of functional networks in the neurocardiology of stress-related cardiomyopathies. However, it is not possible to determine if this role is causal or consequential.

Resumen Antecedentes: Los estudios de neuroimagen funcional podrían ayudar a clarificar la fisiopatología de la miocardiopatía de takotsubo. Objetivo: Revisar la evidencia disponible sobre conectividad funcional cerebral en pacientes con cardiomiopatía de takotsubo. Métodos: Revisión sistemática. Se buscaron en MEDLINE, LILACS, Ovid (Cochrane), Scopus, y ScienceDirect estudios de imagen por resonancia magnética funcional (IRMf) en pacientes con cardiomiopatía de takotsubo. Tras revisar títulos, resúmenes y textos completos se seleccionaron los estudios relevantes, se extrajeron sus características metodológicas y resultados principales, y se valoró su riesgo de sesgo mediante la escala Newcastle-Ottawa. Se presenta revisión narrativa de los resultados. Resultados: Se incluyeron cinco estudios de casos y controles de entre 600 registros. El riesgo de sesgo fue bajo, la comparabilidad fue la principal limitante. Los estudios de IRMf en estado de reposo sugieren diferencias significativas en el Hipocampo, la Ínsula, la Amígdala y el Giro parahipocampal. Los estudios de IRMf bajo paradigma sugieren diferencias en la Ínsula, el Giro occipital superior y en la Amígdala. Los estudios fueron heterogéneos respecto a la lateralización y direccion de estas diferencias. Conclusión: Alteraciones en la conectividad cerebral de zonas relevantes para el control autonómico como la ínsula y la Amígdala provén evidencia a favor del rol de redes funcionales en la neurocardiología de miocardiopatías relacionadas con el estrés. Sin embargo, aún no es posible determinar si esto obedece a un rol causal o consecuencial.

Meta-analysis of incidence and outcomes of life-threatening arrhythmias in takotsubo cardiomyopathy

Background: Takotsubo cardiomyopathy (TC) or stress-induced cardiomyopathy is a transient heart condition that clinically resembles an acute coronary syndrome. This study aims to assess the incidence of life-threatening arrhythmias in patients with Takotsubo cardiomyopathy and evaluate the outcomes of patients with life-threatening arrhythmias (LTAs) in Takotsubo cardiomyopathy compared with those without LTA. Methods: We comprehensively searched the PubMed, Google Scholar, and Embase databases from inception to February 2021. The primary aim of the study was to determine the incidence of LTAs in TC patients. Other outcomes of interest were the odds of in-hospital, long-term mortality, and cardiogenic shock (CS) in TC patients with LTAs versus those without LTAs. For all statistical analyses, ReviewManager and MedCalc were used. Results: Eighteen studies were included in this study involving 55,557 participants (2,185 with LTAs and 53,372 without LTAs). The pooled incidence of LTAs in the patients of TC was found to be 6.29% (CI: 4.70 e8.08%; I2 ¼ 94.67%). There was a statistically significant increased risk of in-hospital mortality (OR ¼ 4.74; CI: 2.24e10.04; I2 ¼ 77%, p < 0.0001) and cardiogenic shock (OR ¼ 5.60; CI: 3.51e8.95; I2 ¼ 0%, p < 0.00001) in the LTA group versus the non-LTA group. LTA was not associated with long-term mortality (OR ¼ 2.23; CI: 0.94e5.28; I2 ¼ 53%, p ¼ 0.07). Conclusion: The pooled incidence of life-threatening arrhythmias in the patients of TC was found to be 6.29%. In the group of TC patients with LTAs, the odds of in-hospital mortality and CS, was higher than in the TC patients without LTAs.

A case of Takotsubo cardiomyopathy with apical hypertrophic cardiomyopathy-like morphological changes during recovery / Journal of Rural Medicine

Objective: Few cases of Takotsubo cardiomyopathy with apical hypertrophic cardiomyopathy (APH)-like morphological changes during the recovery process have been reported.Patient: A 56-year-old woman diagnosed with Takotsubo cardiomyopathy showed a morphology similar to that of APH during recovery. We examined this patient using 2D speckle-tracking echocardiography based on the method used for hypertrophic cardiomyopathy, which suggested that the circumferential strain (CS) of the middle wall indicated myocardial function of the left ventricle, and the CS of the inner wall was associated with left ventricular chamber function.Results: We measured the CS of the endocardial, middle, and epicardial layers and found that the apical inner layer CS (CSinner), middle layer CS, and outer layer CS were all decreased at the onset. CSinner showed a strong tendency to recover on echocardiography performed when APH-like morphology was observed.Conclusion: The morphology of the apex in our case likely contributed to the maintenance of chamber function.

Takotsubo cardiomyopathy in a bedridden patient with dementia and communication difficulties due to Alzheimer’s disease / Journal of Rural Medicine

Takotsubo cardiomyopathy is a transient wall motion abnormality of the left ventricular apex, accompanied by emotional or physical stress. Although Takotsubo cardiomyopathy is generally considered a benign disease, severe clinical complications may occur, and early detection of the disease is important. In this report, we present the case of an 86-year-old bedridden woman with a history of bronchial asthma who was transferred to our hospital because of wheezing. She was diagnosed with Alzheimer’s disease and had communication difficulties. After an asthma attack and improvement, Takotsubo cardiomyopathy was identified via electrocardiography. She was unable to complain of any symptoms but showed serial electrocardiographic changes, elevated myocardial markers, and transient left ventricular apical ballooning. The prevalence of dementia increases dramatically with age. This case indicates that Takotsubo cardiomyopathy may occur even in patients with severe dementia, who are bedridden and show communication difficulties in a clinical setting.

Estrés emocional relacionado con un terremoto como factor causante de un síndrome de takotsubo / Takotsubo syndrome associated with an earthquake. report of two cases

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.

Soporte circulatorio con ECMO venoarterial en paciente con cardiomiopatía de Takotsubo biventricular / Circulatory support with venoarterial ECMO in a patient with biventricular Takotsubo cardiomyopathy

Resumen La cardiomiopatía de Takotsubo es una entidad caracterizada por disfunción ventricular aguda y transitoria, la cual está generalmente relacionada a un evento desencadenante (estrés emocional o físico) y que, por lo general, se presenta con disfunción sistólica regional del ventrículo izquierdo, aunque hasta en un 30% puede ser biventricular. Según su severidad, en algunos casos puede condicionar choque cardiogénico refractario a manejo con inotrópicos y vasopresores, por lo que para estos casos deben considerarse los dispositivos de asistencia circulatoria. Presentamos el caso de una paciente joven a quien se realizó cambio valvular pulmonar con prótesis biológica, la cual siete semanas posteriores a la cirugía acudió al servicio de urgencias con derrame pericárdico y fisiología de tamponade secundario a síndrome pospericardiotomía. Por tal motivo se le practicó ventana pericárdica, sin embargo durante el transquirúrgico presentó cardiomiopatía de Takotsubo biventricular que le condicionó choque cardiogénico con insuficiencia mitral y tricúspidea severas y refractariedad a tratamiento médico, así como a balón intraaórtico de contrapulsación (BIAC), por lo cual requirió soporte circulatorio con ECMO venoarterial durante 5 días.

Abstract Takotsubo cardiomyopathy is an entity characterized by acute and transient ventricular dysfunction, which is usually related to a triggering event (emotional or physical stress), and usually presents with regional systolic dysfunction of the left ventricle, however up to 30% may be biventricular. Depending on its severity in some cases the disease can condition refractory cardiogenic shock to management with inotropics and vasopressors, so for these cases circulatory assistance devices should be considered. We present the case of a young patient who had pulmonary valve change with biological prosthesis, which seven weeks after surgery went to the emergency department with pericardial effusion and tamponade physiology secondary to postpericardiotomy syndrome. For this reason pericardial window was practiced, however during the procedure she presented biventricular Takotsubo cardiomyopathy which conditioned cardiogenic shock with severe mitral and tricuspid regurgitation, and refractivity to medical treatment as well as intraaortic balloon pump, requiring circulatory support with venoarterial ECMO for 5 days.

El síndrome de Takotsubo con taponamiento cardíaco como complicación inusual / Takotsubo syndrome with cardiac tamponade as an unusual complication

Introducción: La miocardiopatía por estrés o síndrome de Takotsubo está asociado a la reducción de la fracción de eyección, niveles elevados de enzimas cardiacas y signos de isquemia en el electrocardiograma. Sin embargo, en pocas ocasiones trascurre con complicaciones tan importantes como el taponamiento cardiaco, deterioro significativo de la contractilidad y la posibilidad de trombos dentro de la cavidad ventricular. Estas son subestimadas a pesar de poner en riesgo la vida del paciente. Objetivo: Describir el caso de una paciente con miocardiopatía por estrés con taponamiento cardiaco como una complicación inusual. Caso clínico: Paciente en la novena década de la vida con antecedente de hipertensión arterial sistémica primaria y enfermedad pulmonar obstructiva crónica. Presentó dolor precordial con trastornos de la contractilidad de patrón usual correspondiente a la cardiomiopatía de Takotsubo en la que se descartaron otros diagnósticos diferenciales. Conclusiones: El caso presentado de miocardiopatía de Takotsubo asociado a una complicación cardiovascular tan importante e inusual como el taponamiento cardiaco, aporta información sobre esta enfermedad infrecuente en nuestro medio(AU)

Introduction: Stress cardiomyopathy or Takotsubo syndrome is associated with reduced ejection fraction, elevated levels of cardiac enzymes and signs of ischemia on the electrocardiogram. However, it rarely occurs with complications as important as cardiac tamponade, significant deterioration of contractility and the possibility of thrombi within the ventricular cavity. These are underestimated despite putting the patient's life at risk. Objective: To describe the case of a patient with stress cardiomyopathy with cardiac tamponade as an unusual complication. Clinical case report: A case of a female patient in her nineties is reported due to her history of primary systemic arterial hypertension and chronic obstructive pulmonary disease. She had chest pain with contractility disorders of the usual pattern corresponding to Takotsubo cardiomyopathy in which other differential diagnoses were ruled out. Conclusions: This case of Takotsubo cardiomyopathy associated with a cardiovascular complication as important and unusual as cardiac tamponade, provides information on this rare disease in our setting(AU)

Dor torácica na emergência: quando pensar em síndrome de Takotsubo? / Emergency chest pain: when to think about Takotsubo syndrome?

A síndrome de Takotsubo é uma cardiomiopatia induzida por estresse, caracterizada por disfunção transitória do ventrículo esquerdo. Essa disfunção pode ser confundida com infarto agudo miocárdio na sala de emergência por ter características clínicas semelhantes ­ principalmente a dor torácica. A fisiopatologia ainda não é bem definida, mas está associada à deficiência de estrogênio e ao aumento de catecolaminas que estimulam o acoplamento dos receptores beta-2 do coração, o que resulta em atividade inotrópica negativa, levando à disfunção contrátil do ventrículo esquerdo. As enzimas cardíacas alteradas dificultam ainda mais o diagnóstico da síndrome de Takotsubo. O exame padrão-ouro, que diferencia a síndrome de Takotsubo do infarto agudo do miocárdio, é a angiografia coronariana. Uma das opções na emergência é o ecocardiograma na beira do leito. Além disso, os critérios de Mayo devem ser usados para diagnosticar a síndrome de Takotsubo. É importante, para o profissional que trabalha no pronto-socorro, ter a síndrome de Takotsubo como diagnóstico diferencial na dor torácica.

Takotsubo syndrome is a stress-induced cardiomyopathy characterized by a transient left ventricular dysfunction. This dysfunction can be confused with acute myocardial infarction in the emergency room as it has similar clinical characteristics, especially chest pain. Its pathophysiology is not yet well defined, but is associated with estrogen deficiency and increased catecholamines that stimulate the coupling of cardiac beta-2 receptors, resulting in negative inotropic activity and leading to contractile dysfunction of the left ventricle. Altered cardiac enzymes make the diagnosis of Takotsubo syndrome even more difficult. The gold standard exam that will differentiate Takotsubo syndrome from acute myocardial infarction is coronary angiography. One of the options in the emergency room is bedside echocardiography. In addition, Mayo criteria should be used to diagnose Takotsubo syndrome. Professionals working in the emergency room shall have Takotsubo syndrome as a differential diagnosis in chest pain.

The Clinical Course of Takotsubo Syndrome Diagnosed According to the InterTAK Criteria

Abstract Background There has been an increase in the number of cases of Takotsubo syndrome (TTS) and of scientific publications on the theme over the last years. However, little is known about the status of this disease in Brazilian hospitals. Objective To assess mortality and major adverse cardiovascular events (MACE) during hospitalization and follow-up of TTS patients seen in a tertiary hospital in Brazil. Methods This was a retrospective, observational study on 48 patients. Clinical data, signs and symptoms, complementary tests, MACE and all-cause mortality were assessed on admission and during follow-up. Kaplan-Meier curves were used for analysis of all-cause mortality and risk for MACE at median follow-up. The 95% confidence interval was also calculated for a significance level of 5%. Results Mean age of patients was 71 years (SD±13 years), and most patients were women (n=41; 85.4%). During hospitalization, four patients (8.3%) died and five (10.4%) developed MACE. At median follow-up of 354.5 days (IQR of 81.5-896.5 days), the risk of all-cause mortality and MACE was 11.1% (95% CI= 1.8-20.3%) and 12.7% (95% CI= 3.3-22.3%), respectively. Conclusion TTS was associated with high morbidity and mortality rates in a tertiary hospital in Brazil, which were comparable to those observed in acute coronary syndrome. Therefore, the severity of TTS should not be underestimated, and new therapeutic strategies are required. Int J Cardiovasc Sci. 2020; [online].ahead print, PP.0-0
