AIMS: Takotsubo syndrome (TTS) is associated with a substantial rate of adverse events. We sought to design a machine learning (ML)-based model to predict the risk of in-hospital death and to perform a clustering of TTS patients to identify different risk profiles. METHODS AND RESULTS: A ridge logistic regression-based ML model for predicting in-hospital death was developed on 3482 TTS patients from the International Takotsubo (InterTAK) Registry, randomly split in a train and an internal validation cohort (75% and 25% of the sample size, respectively) and evaluated in an external validation cohort (1037 patients). Thirty-one clinically relevant variables were included in the prediction model. Model performance represented the primary endpoint and was assessed according to area under the curve (AUC), sensitivity and specificity. As secondary endpoint, a K-medoids clustering algorithm was designed to stratify patients into phenotypic groups based on the 10 most relevant features emerging from the main model. The overall incidence of in-hospital death was 5.2%. The InterTAK-ML model showed an AUC of 0.89 (0.85-0.92), a sensitivity of 0.85 (0.78-0.95) and a specificity of 0.76 (0.74-0.79) in the internal validation cohort and an AUC of 0.82 (0.73-0.91), a sensitivity of 0.74 (0.61-0.87) and a specificity of 0.79 (0.77-0.81) in the external cohort for in-hospital death prediction. By exploiting the 10 variables showing the highest feature importance, TTS patients were clustered into six groups associated with different risks of in-hospital death (28.8% vs. 15.5% vs. 5.4% vs. 1.0.8% vs. 0.5%) which were consistent also in the external cohort. CONCLUSION: A ML-based approach for the identification of TTS patients at risk of adverse short-term prognosis is feasible and effective. The InterTAK-ML model showed unprecedented discriminative capability for the prediction of in-hospital death.

Tako-tsubo kardiomyopatie nebo také stresová kardiomyopatie je poměrně vzácné a ve většině případů reverzibilní onemocnění myokardu. Počáteční projevy mají podobné rysy jako akutní koronární syndrom. Patofyziologický mechanismus není dosud přesně znám. V současnosti je za nejpravděpodobnější příčinu považován nadbytek katecholaminů, který pak má pravděpodobně ústřední roli v omráčení myokardu. Vyplavení katecholaminů mnohdy předchází fyzický či emocionální stres. V první kazuistice předkládáme typický případ pacientky, u níž byl tako-tsubo syndrom vyvolán dlouhodobě trvajícím stresem v zaměstnání, který byl v první fázi považován za infarkt myokardu. Po stanovení diagnózy a následné terapii došlo k úplnému uzdravení pacientky. Ve druhém případě se jednalo o polymorbidní pacientku, u které byl tako-tsubo syndrom diagnostikován po silném emocionálním stresu vyvolaném úmrtím blízké osoby a paralelně probíhající infekcí močových cest. Druhý případ byl doprovázen velmi vzácnou komplikací - rupturou volné stěny levé komory.

Tako-tsubo cardiomyopathy, or stress cardiomyopathy, is a relatively rare and in most cases a reversible disease of the myocardium, with early signs being similar to an acute coronary syndrome. The pathophysiology isn't known to this day, the most accepted theory being an excess of catecholamines that probably plays a key role in stunning the myocardium. Excretion of catecholamines is mostly preceded by physical or emotional stress. In the first case report, we present a typical patient, in which Tako-tsubo syndrome was caused by long-lasting stress at work, being firstly misdiagnosed as a myocardial infarction. After making the diagnosis and proper treatment, the patient made a full recovery. The second case is about a patient with multimorbidity that was diagnosed with Tako-tsubo cardiomyopathy after extreme emotional stress due to the death of a close person, along with an infection of the urinary tract. This case was associated with a very rare complication: a rupture of the left ventricular free wall.

Takotsubo syndrom (TS) je znám i pod označením stresová kardiomyopatie. Spouštěči TS jsou vnější nebo vnitřní, fyzický nebo psychický stres spojený s katecholaminovou bouří, nadměrnou sympatickou aktivitou nervového systému nebo s dysfunkcí mikrovaskulatury v přítomnosti systémového zánětu. Popisujeme případ pacienta s takotsubo kardiomyopatií spojenou s fibrilací síní a s fibromuskulární dysplazií levé přední sestupné větve.

Takotsubo syndrome (TS) is well-known to be a stress-induced cardiomyopathy. TS is triggered by external or internal, physical or emotional stress associated with a catecholamine storm, overactivity of sympathetic nerves, or microvascular dysfunction in the setting of systemic inflammation. We report the case of a patient with Takotsubo cardiomyopathy associated with atrial fibrillation and fibromuscular dysplasia of the left anterior descending artery.

AIMS: Acute pulmonary disorders are known physical triggers of takotsubo syndrome (TTS). This study aimed to investigate prevalence of acute pulmonary triggers in patients with TTS and their impact on outcomes. METHODS AND RESULTS: Patients with TTS were enrolled from the International Takotsubo Registry and screened for triggering factors and comorbidities. Patients were categorized into three groups (acute pulmonary trigger, chronic lung disease, and no lung disease) to compare clinical characteristics and outcomes. Of the 1670 included patients with TTS, 123 (7%) were identified with an acute pulmonary trigger, and 194 (12%) had a known history of chronic lung disease. The incidence of cardiogenic shock was highest in patients with an acute pulmonary trigger compared with those with chronic lung disease or without lung disease (17% vs. 10% vs. 9%, P = 0.017). In-hospital mortality was also higher in patients with an acute pulmonary trigger than in the other two groups, although not significantly (5.7% vs. 1.5% vs. 4.2%, P = 0.13). Survival analysis demonstrated that patients with an acute pulmonary trigger had the worst long-term outcome (P = 0.002). The presence of an acute pulmonary trigger was independently associated with worse long-term mortality (hazard ratio 2.12, 95% confidence interval 1.33-3.38; P = 0.002). CONCLUSIONS: The present study demonstrates that TTS is related to acute pulmonary triggers in 7% of all TTS patients, which accounts for 21% of patients with physical triggers. The presence of acute pulmonary trigger is associated with a severe in-hospital course and a worse long-term outcome.

OBJECTIVE: Takotsubo syndrome (TTS) is characterized by acute left ventricular dysfunction, which can contribute to intraventricular thrombus and embolism. Still, prevalence and clinical impact of thrombus formation and embolic events on outcome of TTS patients remain unclear. This study aimed to investigate clinical features and outcomes of patients with and without intraventricular thrombus or embolism. Additionally, factors associated with thrombus formation or embolism, as well as predictors for mortality, were identified. Approach and Results: TTS patients enrolled in the International Takotsubo Registry at 28 centers in Australia, Europe, and the United States were dichotomized according to the occurrence/absence of intraventricular thrombus or embolism. Patients with intraventricular thrombus or embolism were defined as the ThrombEmb group. Of 1676 TTS patients, 56 (3.3%) patients developed intraventricular thrombus and/or embolism following TTS diagnosis (median time interval, 2.0 days [range, 0-38 days]). Patients in the ThrombEmb group had a different clinical profile including lower left ventricular ejection fraction, higher prevalence of the apical type, elevated levels of troponin and inflammatory markers, and higher prevalence of vascular disease. In a Firth bias-reduced penalized-likelihood logistic regression model apical type, left ventricular ejection fraction ≤30%, previous vascular disease, and a white blood cell count on admission >10×103 cells/μL emerged as independent predictors for thrombus formation or embolism. CONCLUSIONS: Intraventricular thrombus or embolism occur in 3.3% of patients in the acute phase of TTS. A simple risk score including clinical parameters associated with intraventricular thrombus formation or embolism identifies patients at increased risk.

AIMS: Takotsubo syndrome (TTS) is an acute heart failure syndrome, which shares many features with acute coronary syndrome (ACS). Although TTS was initially described with angiographically normal coronary arteries, smaller studies recently indicated a potential coexistence of coronary artery disease (CAD) in TTS patients. This study aimed to determine the coexistence, features, and prognostic role of CAD in a large cohort of patients with TTS. METHODS AND RESULTS: Coronary anatomy and CAD were studied in patients diagnosed with TTS. Inclusion criteria were compliance with the International Takotsubo Diagnostic Criteria for TTS, and availability of original coronary angiographies with ventriculography performed during the acute phase. Exclusion criteria were missing views, poor quality of angiography loops, and angiography without ventriculography. A total of 1016 TTS patients were studied. Of those, 23.0% had obstructive CAD, 41.2% had non-obstructive CAD, and 35.7% had angiographically normal coronary arteries. A total of 47 patients (4.6%) underwent percutaneous coronary intervention, and 3 patients had acute and 8 had chronic coronary artery occlusion concomitant with TTS, respectively. The presence of CAD was associated with increased incidence of shock, ventilation, and death from any cause. After adjusting for confounders, the presence of obstructive CAD was associated with mortality at 30 days. Takotsubo syndrome patients with obstructive CAD were at comparable risk for shock and death and nearly at twice the risk for ventilation compared to an age- and sex-matched ACS cohort. CONCLUSIONS: Coronary artery disease frequently coexists in TTS patients, presents with the whole spectrum of coronary pathology including acute coronary occlusion, and is associated with adverse outcome. TRIAL REGISTRATION: ClinicalTrials.gov number: NCT01947621.

BACKGROUND: Takotsubo syndrome (TTS) occurs predominantly in post-menopausal women but is also found in younger patients. OBJECTIVES: This study aimed to investigate age-related differences in TTS. METHODS: Patients diagnosed with TTS and enrolled in the International Takotsubo Registry between January 2011 and February 2017 were included in this analysis and were stratified by age (younger: ≤50 years, middle-age: 51 to 74 years, elderly: ≥75 years). Baseline characteristics, hospital course, as well as short- and long-term mortality were compared among groups. RESULTS: Of 2,098 TTS patients, 242 (11.5%) patients were ≤50 years of age, 1,194 (56.9%) were 51 to 74 years of age, and 662 (31.6%) were ≥75 years of age. Younger patients were more often men (12.4% vs. 10.9% vs. 6.3%; p = 0.002) and had an increased prevalence of acute neurological (16.3% vs. 8.4% vs. 8.8%; p = 0.001) or psychiatric disorders (14.1% vs. 10.3% vs. 5.6%; p < 0.001) compared with middle-aged and elderly TTS patients. Furthermore, younger patients had more often cardiogenic shock (15.3% vs. 9.1% vs. 8.1%; p = 0.004) and had a numerically higher in-hospital mortality (6.6% vs. 3.6% vs. 5.1%; p = 0.07). At multivariable analysis, younger (odds ratio: 1.60; 95% confidence interval: 0.86 to 3.01; p = 0.14) and older age (odds ratio: 1.09; 95% confidence interval: 0.66 to 1.80; p = 0.75) were not independently associated with in-hospital mortality using the middle-aged group as a reference. There were no differences in 60-day mortality rates among groups. CONCLUSIONS: A substantial proportion of TTS patients are younger than 50 years of age. TTS is associated with severe complications requiring intensive care, particularly in younger patients.

Background Clinical characteristics and outcomes of takotsubo syndrome (TTS) patients with malignancy have not been fully elucidated. This study sought to explore differences in clinical characteristics and to investigate short- and long-term outcomes in TTS patients with or without malignancy. Methods and Results TTS patients were enrolled from the International Takotsubo Registry. The TTS cohort was divided into patients with and without malignancy to investigate differences in clinical characteristics and to assess short- and long-term mortality. A subanalysis was performed comparing long-term mortality between a subset of TTS patients with or without malignancy and acute coronary syndrome (ACS) patients with or without malignancy. Malignancy was observed in 16.6% of 1604 TTS patients. Patients with malignancy were older and more likely to have physical triggers, but less likely to have emotional triggers compared with those without malignancy. Long-term mortality was higher in patients with malignancy (P<0.001), while short-term outcome was comparable (P=0.17). In a subanalysis, long-term mortality was comparable between TTS patients with malignancies and ACS patients with malignancies (P=0.13). Malignancy emerged as an independent predictor of long-term mortality. Conclusions A substantial number of TTS patients show an association with malignancy. History of malignancy might increase the risk for TTS, and therefore, appropriate screening for malignancy should be considered in these patients.

AIMS: We aimed to evaluate the frequency, clinical features, and prognostic implications of cardiac arrest (CA) in takotsubo syndrome (TTS). METHODS AND RESULTS: We reviewed the records of patients with CA and known heart rhythm from the International Takotsubo Registry. The main outcomes were 60-day and 5-year mortality. In addition, predictors of mortality and predictors of CA during the acute TTS phase were assessed. Of 2098 patients, 103 patients with CA and known heart rhythm during CA were included. Compared with patients without CA, CA patients were more likely to be younger, male, and have apical TTS, atrial fibrillation (AF), neurologic comorbidities, physical triggers, and longer corrected QT-interval and lower left ventricular ejection fraction on admission. In all, 57.1% of patients with CA at admission had ventricular fibrillation/tachycardia, while 73.7% of patients with CA in the acute phase had asystole/pulseless electrical activity. Patients with CA showed higher 60-day (40.3% vs. 4.0%, P < 0.001) and 5-year mortality (68.9% vs. 16.7%, P < 0.001) than patients without CA. T-wave inversion and intracranial haemorrhage were independently associated with higher 60-day mortality after CA, whereas female gender was associated with lower 60-day mortality. In the acute phase, CA occurred less frequently in females and more frequently in patients with AF, ST-segment elevation, and higher C-reactive protein on admission. CONCLUSIONS: Cardiac arrest is relatively frequent in TTS and is associated with higher short- and long-term mortality. Clinical and electrocardiographic parameters independently predicted mortality after CA.

Tako-tsubo kardiomyopatie (takotsubo cardiomyopathy, TTC) patří mezi méně častá onemocnění srdce s projevy imitujícími akutní koronární syndrom s elevacemi úseků ST. Vyskytuje se převážně u žen v postmenopauzálním věku. Ve většině případů má onemocnění nekomplikovaný průběh, ale u některých pacientů mohou vzniknout závažné komplikace jako např. kardiogenní šok, těžké srdeční selhání, maligní arytmie, tromboembolická příhoda nebo ruptura myokardu. Kasuistika popisuje případ 82letého muže s TTC komplikovanou rupturou volné stěny levé komory. Tato vzácná komplikace vede ve většině případů k náhlému úmrtí. Vzhledem k neznámé etiopatogenezi je léčba tohoto onemocnění zatím pouze symptomatická. Farmakoterapie je stále otázkou diskusí a dalšího výzkumu.

Takotsubo cardiomyopathy (TTC) belongs to rare heart disease with symptoms imitating acute coronary syndrome with ST segment elevation. Usually, it occurs predominantly in women at the age of postmenopause. In most cases, the disease has an uncomplicated course, but some patients may develop severe complications (e.g. cardiogenic shock, severe heart failure, malignant arrhythmia, thromboembolism or myocardial wall rupture). Case report describes an 82-year-old man with TTC complicated by rupture of the left ventricular free wall and interventricular septum. This rare complication often leads to sudden death. Due to the unknown etiopathogenesis the treatment is symptomatic. Pharmacologic therapy is still a matter of debate and further research.
