RESUMEN

BACKGROUND: Takotsubo syndrome (TTS) is an acute heart failure syndrome with symptoms similar to acute myocardial infarction. TTS is often triggered by acute emotional or physical stress and is a significant cause of morbidity and mortality. Predictors of mortality in patients with TS are not well understood, and there is a need to identify high-risk patients and tailor treatment accordingly. This study aimed to assess the importance of various clinical factors in predicting 30-day mortality in TTS patients using a machine learning algorithm. METHODS: We analyzed data from the nationwide Swedish Coronary Angiography and Angioplasty Registry (SCAAR) for all patients with TTS in Sweden between 2015 and 2022. Gradient boosting was used to assess the relative importance of variables in predicting 30-day mortality in TTS patients. RESULTS: Of 3,180 patients hospitalized with TTS, 76.0% were women. The median age was 71.0 years (interquartile range 62-77). The crude all-cause mortality rate was 3.2% at 30 days. Machine learning algorithms by gradient boosting identified treating hospitals as the most important predictor of 30-day mortality. This factor was followed in significance by the clinical indication for angiography, creatinine level, Killip class, and age. Other less important factors included weight, height, and certain medical conditions such as hyperlipidemia and smoking status. CONCLUSIONS: Using machine learning with gradient boosting, we analyzed all Swedish patients diagnosed with TTS over seven years and found that the treating hospital was the most significant predictor of 30-day mortality.

RESUMEN

BACKGROUND: Electroconvulsive therapy (ECT) is a safe treatment for treatment-resistant schizophrenia. However, it has some side effects, and Takotsubo cardiomyopathy is considered one of the minor complications. Several cases of patients developing Takotsubo cardiomyopathy during a course of ECT have been reported, but none have died. We present a case of post-ECT Takotsubo cardiomyopathy that became fatal. CASE PRESENTATION: We experienced a case of a 67-year-old woman who had delusions and catatonic symptoms due to schizophrenia but was resistant to several medications. Her symptoms improved by conducting ECT, but she had difficulty maintaining her improvement, which caused her to receive multiple courses of ECT. 3 weeks after her 6th course of ECT, the patient was diagnosed with Takotsubo cardiomyopathy and had a fatal outcome. CONCLUSION: Our patient had numerous cases of aspiration pneumonia and malnutrition before ECT was performed, which might have made this case fatal. In conclusion, appropriate supplementation of nutrition and reduction of physical stressors are important to avoid death from Takotsubo cardiomyopathy caused by ECT. Prescribing clozapine was a solution in the present case, but there are some difficulties, such as the restriction against prescribing this drug in Japan.

RESUMEN

Takotsubo syndrome (TTS), also known as stress-induced cardiomyopathy, is characterized by acute heart failure, reversible left ventricular dysfunction, and other complications such as life-threatening arrhythmias. The management of TTS is challenging due to its unpredictable clinical course and the lack of evidence-based treatment recommendations. In this case report, we present a 71-year-old female who developed TTS with ventricular tachycardia (VT) cardiac arrest following septic shock and an exploratory laparotomy for appendicitis. Despite the presence of VT cardiac arrest and a left ventricular ejection fraction of 30-35%, an implanted cardioverter-defibrillator (ICD) was not indicated due to the rapid and satisfactory recovery of the patient's ventricular function. This case highlights the importance of considering the clinical context and the transient nature of TTS in the decision-making process for ICD candidacy.

RESUMEN

Various rates of the short- and long-term recurrence of takotsubo syndrome (TTS) (RTTS) have been reported, but the absence, or the short length of the follow-up implemented is such, that the true rate of RTTS continues to be unknown. Experience has shown that a sizeable proportion of patients with an index TTS suffer a RTTS episode beyond 5 years, and even 20 years later. In a cohort of 215 patients with RTTS from the world literature, a mean of 30.2 and 37.2 months separated the index TTS from the 1st and last RTTS episodes, respectively, with 21.9 % of patients suffering more than 1 RTTS episode, over a course of maximum of 20 years. Also, 39.5 % and 19.5 % of patients had their only or last RTTS episode(s), at or beyond the 3rd and 5th year of follow-up, respectively. The true rate of RTTS is unknown, probably is higher that currently reported, and it is hoped that existing registries may provide the answer, if they implement an open-ending long-term follow-up of their registered patients.

RESUMEN

BACKGROUND: Takotsubo syndrome (TS) during pregnancy and postpartum is rare but may lead to significant maternal and fetal morbidity. We compared clinical characteristics and prognosis according to [a] timing of presentation (pregnancy vs post-partum) and [b] modes of delivery (cesarean section vs vaginal delivery). METHODS: Systematic review of articles published in PubMed, Scopus, Embase, and Medline databases from inception to July 30, 2023. Patient demographics, obstetric, electrocardiographic, laboratory, echocardiographic characteristics, and prognosis were summarized descriptively. RESULTS: An initial database search identified 2162 articles, of which 81 studies were included in this review. TS during pregnancy can have emotional, obstetric, and metabolic triggers and has a higher proportion of adverse fetal outcomes when compared with women who developed TS postpartum. Women with TS after cesarean section had an earlier onset and higher proportion of anesthesia use when compared with those who developed TS after vaginal delivery. There were no differences regarding the degree of systolic dysfunction or the need for advanced therapies, including ventilator support, intra-aortic balloon pump, and extracorporeal membrane oxygenation among groups. CONCLUSIONS: TS is associated with various triggers and adverse fetal outcomes when it develops during pregnancy than in the postpartum period. TS occurs more rapidly and with a more aggressive course after cesarean section than after vaginal delivery.

RESUMEN

BACKGROUND: Emotional stress is a common precipitating cause of takotsubo cardiomyopathy (TC). Preexisting psychiatric disorder (PD) was linked to worsening outcomes in patients with TC1,2. However, there is limited data in literature to support this. This study aimed to determine the differences in outcomes in TC patients with and without PD. METHODS: We identified all patients with a diagnosis of TC using the National Inpatient Sample (NIS) and the National Readmission Database (NRD) data from 2016 to 2018. The patients were separated into TC with PD group and TC without PD group. Multiple variable logistic regression was then performed. RESULTS: Using NIS 2016-2018, we identified 23,220 patients with TC, and 43.11% had PD. The mean age was 66.73 ± 12.74 years, with 90.42% being female sex. The TC with PD group had a higher 30-readmission rate 1.25 (95% CI:1.06-1.47), Cardiogenic shock [aOR = 7.3 (95%CI 3.97-13.6), Mechanical ventilation [aOR = 4.2 (95%CI 2.4-7.5), Cardiac arrest [aOR = 2.6 (95%CI 1.1-6.3), than TC without PD group. CONCLUSION: Psychiatric disorders were found in up to 43% of patients with TC. The concomitant PD in TC patients was not associated with increased mortality, AKI, but had higher rates of cardiogenic shock, use of mechanical ventilation and cardiac arrest. The TC group with PD was also associated with increased 30-day readmission, LOS and total charges compared to TC patients without PD.

RESUMEN

Tako-Tsubo syndrome (TTS) presents as transient ventricular dysfunction, yet its underlying pathophysiology remains enigmatic. The prognosis of patients presenting with TTS appears to be impaired as compared to the general population and is similar to patients with acute coronary syndromes. Recent investigations have predominantly focused on elucidating therapeutic strategies associated with improved outcomes, particularly among post-menopausal female patients. Current evidence suggests that angiotensin-converting enzyme inhibitors (ACEi) may confer a survival advantage in TTS. Notably, ACEi emerges as the sole therapeutic modality demonstrating efficacy in both acute and chronic clinical courses of TTS. Despite this, the magnitude of survival benefit remains less pronounced than anticipated. This underscores the need for further research to explore additional therapeutic pathways and optimize management strategies for this unique patient cohort. Randomized clinical trials and meta-analysis are paramount in discerning the most effective therapeutic interventions aimed at enhancing survival and ameliorating outcomes in TTS. This review aims to comprehensively synthesize evidence pertaining to the prognostic implications of cardiovascular medications in TTS management.

RESUMEN

BACKGROUND: Takotsubo cardiomyopathy is a novel form of rapidly reversible heart failure occurring secondary to a stressor that mimics an acute coronary event. The underlying etiology of the stressor is highly variable and can include medical procedures. Pacemaker insertion is an infrequent cause of Takotsubo cardiomyopathy. CASE PRESENTATION: An 86-year-old Caucasian woman underwent an uncomplicated pacemaker insertion for symptomatic complete heart block in the background of slow atrial fibrillation. A transient episode of polymorphic ventricular tachycardia was noted on day 1 following the procedure; however, her pacemaker was checked and, as she remained stable, she was discharged home. She presented again 5 days later with symptomatic heart failure. Chest X-ray confirmed pulmonary edema. Echocardiography confirmed new onset severe left ventricle dysfunction. Pacemaker checks were normal and lead placement was confirmed. Though her troponin I was elevated, her coronary angiogram was normal. Contrast enhanced echocardiography suggested apical ballooning favoring Takotsubo cardiomyopathy. She was treated for heart failure and made a good recovery. Her follow-up echocardiography a month later showed significant improvement in left ventricle function. CONCLUSIONS: Takotsubo cardiomyopathy is mediated by a neuro-cardiogenic mechanism due to hypothalamic-pituitary-adrenal axis activation. It generally has a good prognosis. Complications though uncommon, can occur and include arrhythmias. Pacemaker insertion as a precipitant stressor is an infrequent cause of Takotsubo cardiomyopathy. As pacemaker insertions are more frequent in the elderly age group, this phenomenon should be recognized as a potential complication.

RESUMEN

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.

RESUMEN

Tako tsubo cardiomyopathy associated with left ventricular outflow tract obstruction (LVOT) is a rare cause of persistent perioperative hypotension. One of the causes of this association is the systolic anterior motion (SAM) of the mitral valve. We report a case of a 67-year-old woman who, after undergoing liver segmentectomy because of metastasis, presents post-operative hypotension that is difficult to manage. Upon evaluation with a transthoracic echocardiogram, the diagnostic suspicion of Tako tsubo syndrome associated with LVOT obstruction secondary to SAM was raised. As initial therapy, a volume expander, in association with propanolol and phenylephrine were administred, achieving partial hemodynamic response. Later, she evolved with signs of heart failure and was transferred to the intensive care unit for management. In this unit, non-invasive ventilatory support, diuretic and vasopressor therapy were required, achieving favorable results on the second post-operative day. Echocardiography was essential to make the differential diagnosis against a persistent post-operative hypotension


La cardiomiopatía de Tako tsubo asociada a obstrucción del tracto de salida del ventrículo izquierdo (TSVI) es una causa poco frecuente de hipotensión persistente en el perioperatorio. Uno de los motivos de esta asociación es el movimiento anormal sistólico (SAM) de la válvula mitral. A continuación, presentamos el caso de una mujer de 67 años que, tras ser sometida a segmentectomía hepática por metástasis, presenta cuadro de hipotensión postoperatoria de difícil manejo. Al ser evaluada con ecocardiograma transtorácico se plantea la sospecha diagnóstica de síndrome de Tako tsubo asociado a obstrucción del TSVI secundario a SAM. Como terapia inicial se realizó aporte de volumen, en asociación con propanolol y fenilefrina, logrando parcial respuesta hemodinámica. Posteriormente, evolucionó con signos de insuficiencia cardiaca y fue trasladada a unidad de cuidados intensivos para su manejo. En esta unidad requirió apoyo ventilatorio no invasivo, terapia diurética y vasopresora, logrando resultados favorables al segundo día postoperatorio. La ecocardiografía fue fundamental para realizar el diagnóstico diferencial frente a un cuadro de hipotensión postoperatoria persistente.

RESUMEN

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.

RESUMEN

El síndrome de Tako-Tsubo es caracterizado por una disfunción transitoria del ventrículo izquierdo (VI), con cambios electrocardiográficos y elevación de enzimas cardiacas que simulan un infarto agudo de miocardio (IAM) en ausencia de enfermedad coronaria obstructiva (ECO). Los reportes de síndrome de Tako-Tsubo luego de una cirugía cardiaca son excepcionales. Se describe el caso clínico de una mujer de 58 años que tras cirugía de reemplazo valvular mitral electiva desarrolla disfunción ventricular severa y shock cardiogénico, su evolución fue favorable con recuperación de la contractilidad hasta la normalidad. El síndrome de Tako-Tsubo debe ser considerado como un diagnostico diferencial en pacientes que presentan shock cardiogénico después de una cirugía cardiaca.

RESUMEN

La cardiomiopatía de Tako-Tsubo se define como una cardiopatía súbita, aguda, caracterizada por alteraciones en la contractilidad de los segmentos apicales del ventrículo izquierdo, lo que lleva de manera rápida e importante a un defecto de bomba a nivel cardíaco, causando sintomatología de diversa gravedad que puede implicar incluso el desarrollo de choque cardiogénico y la muerte. Se caracteriza, entre otros, por una ausencia absoluta de lesiones detectables a la angiografía coronaria. A pesar que no existe a la fecha un consenso al respecto, actualmente se considera que las teorías que mejor explican el síndrome son las alteraciones de la microcirculación coronaria y la toxicidad miocárdica por catecolaminas. Su cuadro clínico se basa principalmente en dolor precordial, asociado a disnea; las enzimas de mionecrosis (principalmente las troponinas) pueden estar aumentadas levemente, aunque es característica la presencia de una coronariografía completamente normal.


Tako-Tsubo cardiomyopathy is defined as a sudden, acute cardiomyopathy, characterized by reversible alterations in left ventricle’s apical segments contractility, resulting in an important decrease in the heart’s ‘pumping’ function. This causes various degrees of symptomatology in the patient, including, in some cases, cardiogenic shock and death. This condition is characterized, specially, by an absolute lack of detectable lesions on coronariography. Although to date there is no consensus on this issue, now considered the theories that best explain the syndrome include abnormalities of the coronary microcirculation and myocardial catecholamine toxicity. The clinical presentation of most patients will include chest pain and dyspnea, with troponins been elevated in some cases, although there will always be the characteristic of a completely normal angiographic study.
