RESUMEN
Takotsubo cardiomyopathy (TCM) is characterized by transient left ventricular dysfunction, diagnosed via echocardiography or left ventriculography. In most cases, TCM involves an emotional, physical, or combined trigger. Acute coronary syndrome is one of the most frequent misdiagnoses in TCM patients due to electrocardiogram (ECG) abnormalities and elevated cardiac biomarkers. Typically, coronary angiography reveals no stenosis or occlusion of the coronary arteries. Hypertrophic cardiomyopathy (HCM) is a distinct pathology characterized by a hypertrophied left ventricle with various phenotypes. However, some reports have described TCM cases mimicking obstructive-type HCM in some patients. We present a case of a female patient diagnosed with TCM based on clinical, laboratory, and imaging tests. Differentiating TCM from HCM was challenging due to ventriculography and echocardiography findings, as hyperdynamic contraction of the basal segments of the left ventricle caused an increased left ventricular outflow tract (LVOT) gradient and severe mitral valve regurgitation. Detailed evaluation and close echocardiographic follow-up are essential in such rare cases.

BACKGROUND Pheochromocytoma, a rare catecholamine-secreting tumor, often presents with paroxysmal or sustained hypertension, tachycardia, headache, and diaphoresis. Timely diagnosis is essential to prevent adverse complications. Less common presentations include pheochromocytoma crisis, with severe neurological and cardiac complications. CASE REPORT We report a unique case of a 25-year-old woman who initially presented with pheochromocytoma-induced hypertensive encephalopathy and acute coronary syndrome. Echocardiography revealed takotsubo-like cardiomyopathy, and magnetic resonance imaging of the brain revealed posterior reversible encephalopathy syndrome. Initial treatment focused on controlling her blood pressure and supporting cardiac function. Due to her recovering from immediate crisis and absence of further symptoms, the patient refused further follow-up. However, she eventually experienced another episode of hypertensive crisis 2 years later. Subsequent investigations with 24-h urine tests revealed elevated vanillylmandelic acid levels (7.93 mg/24 h), normetanephrine (2638.72 µg/24 h), and nor-metanephrine to creatinine ratio (3546.67) and normal urine metanephrine levels (195.92 µg/24 h) and metanephrine to creatinine ratio (263.33). Contrast-enhanced computed tomography of the abdomen revealed a 4.3×3.1×4-cm mass in the right adrenal gland. A DOTATATE positron emission tomography scan revealed a 3.9×4.3×2.7-cm localized right adrenal pheochromocytoma. Biochemical testing and adrenal imaging revealed a previously undiagnosed pheochromocytoma. Following targeted medical therapy and right adrenalectomy, the patient achieved complete resolution of her hypertension and associated symptoms. CONCLUSIONS Our case is a unique simultaneous presentation of posterior reversible encephalopathy syndrome and takotsubo-like cardiomyopathy, highlighting the importance to consider pheochromocytoma in acute neurological and cardiac presentations, even in the absence of typical symptoms.

BACKGROUND: Myocardial bridging is a cardiac anomaly where a segment of epicardial coronary arteries runs through the myocardium and can rarely cause MI. Takotsubo syndrome is a stress-induced cardiomyopathy that can mimic MI. Catecholamine surge during stress can contribute to Takotsubo syndrome, but whether this surge can trigger an inconspicuous myocardial bridging to manifest symptomatically remains unclear, and alternately, whether a myocardial bridge might cause worsening of Takotsubo syndrome is also a matter that needs further research. CASE PRESENTATION: We report the case of a patient who initially presented with features of acute exacerbation of bronchiectasis and subsequently developed symptoms and ECG features suggestive of acute myocardial infarction. Echocardiography revealed features of takotsubo syndrome, and complete myocardial bridging was revealed via coronary angiography. The patient was managed conservatively with pharmacological treatment, and after a few days, echocardiographic features were reversed. As such, the diagnosis shifted toward Takotsubo syndrome with myocardial stunning due to co-existent myocardial bridging. CONCLUSION: We report a rare case of a patient with acute bronchiectasis exacerbation with features suggestive of acute myocardial infarction who had findings of Takotsubo syndrome and complete myocardial bridging. In the beginning, it was difficult to determine whether the symptoms arose due to acute MI resulting from myocardial bridging or were solely due to takotsubo syndrome because of stress from bronchiectasis. Although myocardial bridging is often overlooked as an etiology for acute MI, this case highlights the importance of expanding the differential diagnosis to myocardial bridging in the work-up for the cause of acute MI and how Takotsubo syndrome can mimic acute MI and pose a diagnostic challenge.

INTRODUCTION: Takotsubo syndrome (TTS) is an acute transient nonischemic cardiomyopathy often characterized by its hallmark feature of left ventricular apical ballooning. The correlation between racial backgrounds and the prognosis of individuals with TTS remains poorly defined. Our study aimed to explore the influence of race on the trends, clinical presentations, and outcomes in patients diagnosed with TTS. METHODS: We queried the National Inpatient Sample (NIS) database from 2016 to 2020 and identified hospitalizations with TTS. We compared the clinical features and outcomes across three different races - non-Hispanic White (NHW), non-Hispanic Black (NHB), and Hispanic population. The primary outcome was in-hospital mortality. RESULTS: 76,505 weighted hospitalizations for TTS were identified, of which 65,495 (85.6%) were non-Hispanic White, 5,830 (7.6%) were non-Hispanic Black, and 5,180 (6.8%) were Hispanics. After propensity-score matching, NHB patients had higher odds of acute kidney injury (OR: 1.49, 95% CI: 1.21-1.84, p < 0.001) and mechanical ventilation (OR: 1.33, 95% CI: 1.04-1.68, p = 0.02). Hispanic patients had a higher incidence of acute kidney injury requiring dialysis when compared to NHW patients (OR: 2.53, 95% CI: 1.11-5.77, p = 0.027). There was no significant difference in terms of in-hospital mortality between NHB and Hispanic patients when compared to NHW patients. Notably, Hispanic populations experienced a higher mortality rate during the COVID-19 period. CONCLUSION: Our study suggested significant differences in the outcomes of TTS across different racial groups. Hispanic populations experienced a higher mortality rate with TTS during the COVID-19 era. Further research should emphasize discovering the factors contributing to the observed disparities.

Takotsubo syndrome (TTS) might exhibit particular chronobiological patterns in its onset, characterized by variations according to time of the day, day of the week, and month of the year. The aim of this study was to fully explore the temporal patterns (circadian, weekly and seasonal) in the onset of TTS. A systematic review and meta-analysis of literature were conducted for studies (2006-2024) reporting the temporal patterns (circadian, weekly and/or seasonal) in the onset of TTS. Among the 4257 studies retrieved, 20 (including 64,567 subjects) fulfilled all eligibility criteria. Data were aggregated used random effects model as pooled risk ratio and the attributable risk (AR). The proportion analysis (including 8 studies; n=853) showed a decreasing pattern of the pooled rates of TTS shifting from the morning to the night (pooled TTS rates: 34.0%; 32.1%; 21.7%; 12.7% in the morning, afternoon, evening and night, respectively). The same pattern was observed stratifying by type of preceding stressful factor or event, considering physical stressors (pooled rates in the morning and night: 37.6% and 9.8%, respectively), and also in case no event could be identified. The pooled rates of TTS onset peaked on Monday and Tuesday (17.3% and 18.4% respectively), then declined during the week, reaching the lowest rates on Friday and Saturday (10.6% and 10.8%, respectively), with no sex differences. TTS onset reached the highest values on summer, and the lowest in winter (27.9% versus 21.7% in summer and winter, respectively). The TTS morning peak based analyses (â¼33% of all the registered events) account for a RR of 1.46 (95% CI: 1.38-1.54), the week-based for a RR of 1.26 (1.16-1.35), the season-based for a RR of 1.04 (1.04-1.05). TTS onset exhibits specific chronobiological patterns, characterized by a peak during the morning hours, and on Monday and Tuesday. Differing from other cardiovascular emergencies TTS was more frequent during summer. Further studies are needed to fully understand the underlying pathophysiological mechanisms in order to tailor relative management and preventive strategies.

BACKGROUND: This study aimed to evaluate the impact of race on in-hospital outcomes of Takotsubo cardiomyopathy using the National Inpatient Sample. METHODS AND RESULTS: We conducted a retrospective study using data from the National Inpatient Sample database 2006 to 2018. We focused on Takotsubo cardiomyopathy hospitalizations, excluding those with acute coronary syndrome as the primary diagnosis. Two study groups consisted of White patients or Black patients. Univariate and multivariable logistic models evaluated race's effect on death, cardiac arrest, cardiogenic shock, length of stay, while adjusting for potential confounders. The Bayesian model averaging technique was used to further elucidate the factors influencing death within each racial group. Significant differences were observed between the 2 racial groups. Black patients presented at a younger age, had a higher proportion of men, a higher burden of comorbidities, and a lower median household income compared with their White counterparts. In the univariate model, the Black cohort showed an increased risk of cardiac arrest (odds ratio, 1.45 [95% CI, 1.15-1.82]). However, the difference did not reach statistical significance in the multivariable model. Black patients also had a significantly longer hospital stay in both the univariate model (risk ratio, 1.26 [95% CI, 1.22-1.31]) and the multivariable model (risk ratio, 1.06 [95% CI, 1.04-1.07]). No significant difference in all-cause death was observed between the racial groups. CONCLUSIONS: The outcome differences between 2 racial groups in our study are likely influenced by racial disparities in demographics, comorbidities, and socioeconomic factors. Individualized care based on racial group needs is crucial in clinical practice.

The predictive value of various ECG repolarization markers for the emergence of VA in patients with TTS was reviewed. The literature reports on QT, more recently on Tpe, and rarely on some more QT-derived metrics, revealing a contribution of these variables for the prediction of VA, complicating the acute, subacute, and follow-up clinical trajectory of patients with TTS. More recent literature reveals that Tpe and some other QT-based metrics, have outperformed the traditionally employed QT marker, although certainty about this awaits confirmation by future carefully designed and implemented studies.

Blunt chest trauma (BCT) may rarely trigger stress-induced takotsubo syndrome (TTS) which requires dif f erential diagnosis with myocardial contusion and BCT-induced myocardial infarction. So far reported cases have been presented as apical ballooning or inverted (reverse) TTS forms but not as a midventricular variant. The authors described a case of a 53-year-old female admitted to Intensive Care Unit after motor vehicle accident with BCT and airbag deployment during car roll over. For some time after the accident, she was trapped in a car with her head bent to the chest. After being pulled out from the car, she had impaired consciousness and therefore was intubated by the rescue team. Trauma computed tomography scan did not reveal any injuries. However, ECG showed ST-segment depression in II, III, aVF, V4-6, and discrete ST-segment elevation in aVR. Troponin I and NTpro-BNP increased to 2062 ng/l and 6413 pg/ml, respectively. Echocardiography revealed mild midventricular dysfunction of the left ventricle with ejection fraction (EF) and global longitudinal strain (GLS) reduced to 45% and -17.6%, respectively. On day two, the patient's general condition improved and stabilized, so she was extubated. Normalization of ECG, EF and GLS (but not regional LS) was observed on day three. She was discharged home on day fi ve. Post-hospital examinations documented that segmental longitudinal strain remained abnormal for up to 4 weeks. The authors conclude that fast ECG and echocardiographic evolution may result in underestimation of the posttraumatic TTS diagnosis, especially if it takes atypical form and its course is mild. Longitudinal strain evaluation can be helpful in cardiac monitoring of trauma patients.

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.

BACKGROUND: Takotsubo syndrome (TS) is a reversible cause of heart failure; however, a minority of patients can develop serious complications, including cardiac rupture (CR). OBJECTIVES: Analyze case reports of CR related to TS, detailing patient characteristics to uncover risk factors and prognosis for this severe complication. METHODS: We conducted a systematic search of MEDLINE and Embase databases to identify case reports of patients with TS complicated by CR, from inception to October 2023. RESULTS: We included 44 subjects (40 females; 4 males) with a median age of 75 (IQR 71-82) years, of White/Caucasian (61%) or East Asian/Japanese (39%) ethnicity. An emotional trigger was present in 15 (34%) subjects and an apical ballooning pattern was observed in all cases (100%). ST-segment elevation was reported in 39 (93%) of 42 cases, with the anterior myocardial segments (37 [88%]) being the most compromised, followed by lateral (26 [62%]) and inferior (14 [33%]) segments. The median time to cardiac rupture was 48 (5-120) hours since admission, with the left ventricular free wall (25 [57%]) being the most frequent site of perforation. Surgery was attempted in 16 (36%) cases, and 28 (64%) patients did not survive. CONCLUSIONS: CR related to TS is a rare complication associated with high mortality and affecting elderly females, specially from White/Caucasian or East Asian/Japanese descent, presenting with anterior or lateral ST-segment elevation, and an apical ballooning pattern. Although data is limited and additional prospective studies are needed, the awareness of this life-threatening complication is crucial to early identify high-risk patients. CONDENSED ABSTRACT: Cardiac rupture is a rare complication of Takotsubo syndrome. We conducted a systematic review of cases complicated by cardiac rupture, and we identified 44 subjects (40 females and 4 males) with a median age of 75 (IQR 71-82) years, of White/Caucasian (61%) or East Asian/Japanese (39%) ethnicity, all with an apical ballooning pattern (100%). The median time to cardiac rupture was 48 (5-120) hours since admission, with the left ventricular free wall (25 [57%]) being the most frequent site of perforation. Surgery treatment was attempted in 16 (36%) cases, and 28 (64%) patients did not survive.

There is ample literature revealing an association of SCAD with TTS, while it is not clear whether these 2 pathological entities are mechanistically linked in the sense that the one triggers the other. Considering that physical/emotional stress triggers TTS, it is plausible that stress related to SCAD, could result in the emergence of TTS. Conversely, it has been speculated that the junction between hypercontractile and akinetic/dyskinetic myocardium regions in TTS could lead to a "hinge pivoting point", imparting vascular disruption in coronary arteries, crossing these abutting myocardial planes, in susceptible individuals, causing SCAD.

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.

BACKGROUND: Differentiating Takotsubo cardiomyopathy (TTC) from acute coronary syndrome involving the left anterior descending coronary artery (LAD-ACS) is difficult due to left ventricular apical wall motion abnormality pattern in both and typically requires an invasive coronary angiography (ICA) study for diagnostic confirmation. OBJECTIVES: To identify differences in the regional wall motion abnormality (RWMA) pattern using a comprehensive comparative analysis of the transthoracic echocardiographic (TTE) findings in patients with TTC versus LAD-ACS. METHODS: This was a retrospective, randomized, blinded comparison study including a derivation cohort of 105 patients with TTC (N=52) or LAD-ACS (N=53) with concomitant TTE and ICA identified from our institutional database. A comprehensive echocardiographic wall motion analysis was performed (unblinded) to search for subtle differences in RWMA patterns by marking the exact locations of the end-systolic hinge points (HP) - defined as the intersection between the normal and abnormal regional myocardial thickening - in all apical views. The HP location relative to mitral annulus in each apical view was compared for symmetry and the apical 2-chamber (A2C) view was identified as having the most consistent, quantitative difference between TTC and LAD-ACS. This A2C quantitative model was then prospectively studied in a randomized, blinded, validation cohort of 30 subjects with either TTC or LAD-ACS by eight echocardiographic readers with all levels of clinical experience. RESULTS: In the unblinded derivation cohort, the A2C view showed that the ratio (1.02) and the absolute distance between the anterior HP (3.57 cm) and the inferior HP (3.53 cm) in TTC was significantly different than the ratio (0.761) and the absolute differences between the AHP (4.5 cm) and the IHP (5.93 cm) in LAD-ACS. An AHP: IHP of 0.96 for men and 0.84 for women was able to correctly categorize 84.8% of male and 91.7% of female patients. When applied to the validation cohort, the model showed fairly accurate results with a 74% prediction rate in diagnosing TTC in female patients. CONCLUSION: We propose a relatively simple 2-D TTE diagnostic tool emphasizing subtle differences in the RWMA pattern in the A2C view alone as a semi-quantitative imaging parameter to help differentiate TTC from LAD-ACS.
