Abstract
BACKGROUND Owing to the limited research on Takotsubo Cardiomyopathy (TCM) in Asia, we aim to evaluate in detail the clinical profiles, lab parameters, investigations, and major adverse cardiovascular events (MACE) seen in patients with TCM in the Indian subcontinent. Additionally, we have compared the electrocardiographic findings of patients with TCM to those of patients with myocardial infarction (MI). RESULTS The average age of the patients affected was found to be 60 ± 11 years. Women (87.5%) and patients with hypertension (40%) were found to be at an increased risk of developing the syndrome. The most common presenting symptom was dyspnea (48%) following a trigger most commonly emotional (45%). ST elevation and significant T wave inversions were observed in 40% of patients with TCM. Echocardiography revealed a low left ventricular ejection fraction of 43 ± 9%. Coronary angiography was normal in 60%, the rest had mild/subcritical stenoses. The 6-month MACE was 20% and the mortality rate was 7.5%. Follow-up echocardiography of patients with TCM showed improvement in EF in 75% patients. CONCLUSIONS TCM was majorly seen in postmenopausal women following an emotional trigger, but a variety of other triggers were noted. T-wave inversions in TCM follow a diffuse pattern in contrast to specific leads seen in MI. Normal or subcritical stenosis in coronaries at presentation, along with a low EF which improves on follow up provide greater evidence for the diagnosis of TCM.

Abstract
Takotsubo cardiomyopathy (TCM) is a syndrome of reversible left ventricular systolic dysfunction that, at presentation, can be easily conflated with acute coronary syndrome. TCM has a clinical preponderance for older, postmenopausal females. We report on a patient’s case who presented with complaints of upper and lower extremity weakness with evidence of rhabdomyolysis and hepatic injury. Her occupation as a field worker exposed her to a toxic chemical known as paraquat, which has been banned by multiple countries across the world; a chemical we presume culminated in both. The subsequent clinical cascade and resulting acute physiological illness and emotional distress primed her to develop TCM. However, she neither endorsed chest pain nor dyspnea. Her subtle clinical presentation could have led to a missed diagnosis as she was also not in a fluid overloaded state consistent with the depressed left ventricular function discovered on transthoracic echo. The diagnostic uncertainty until coronary angiography is obtained, and its association with severe and acute emotional and physical stress prompts to a greater reliance on patient history to identify occupational and toxic exposures that can contribute to its development.

Abstract
Takotsubo Cardiomyopathy (TC) is a syndrome characterized by reversible left ventricular dysfunction in the presence of possible emotional or physical triggers but without evidence of obstructive coronary artery disease. It has become increasingly reported worldwide and is associated with significant morbidity and mortality. TC may present with an array of electrocardiographic (ECG) findings. These ECG findings, if accurately interpreted, can play an important role in the diagnosis and risk stratification of this syndrome. In the last three decades since the disease was first described, multiple diagnostic criteria have been established. The key diagnostic tools for TC include clinical symptomatology, cardiac biomarkers, non-invasive cardiac imaging, and coronary angiography. The ECG findings in TC can be variable, however, some ECG scores have been proposed in association with TC with reasonably good diagnostic sensitivity and specificity. This article aims to provide a succinct review of important electrocardiographic findings associated with TC and its impact on clinical outcomes.

Left Ventricular Sphericity Index is a reproducible bedside echocardiographic measure of geometric change between acute phase Takotsubo's syndrome and acute anterior myocardial infarction. IJC HEART & VASCULATURE 2020; 29:100547. [PMID: 32514426 PMCID: PMC7267721 DOI: 10.1016/j.ijcha.2020.100547] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2020] [Revised: 05/13/2020] [Accepted: 05/25/2020] [Indexed: 12/15/2022]
Abstract
TS and AMI are separate cardiac conditions with similar clinical presentations. TS have a higher LVSI than AMI, indicating a more spherical left ventricle. LVSI may be utilised acutely to assist differentiation of acute phase TS and AMI.
Background Left ventricular sphericity index (LVSI) is a simple, quick and reproducible measure to evaluate LV geometric changes. The aim of our study was to evaluate the utility of LVSI as a rapid discrimination tool in two disease processes; Takotsubo’s Syndrome (TS) and Anterior Myocardial Infarction (AMI), in the absence of significant left ventricular systolic dysfunction. Methods Consecutive patients with acute phase TS admitted to our institution (Jan 2013 - Dec 2018) were evaluated (n=66). Patients with a comprehensive two-dimensional transthoracic echocardiogram were included in primary analysis (n=50) and age-matched with a cohort of patients with acute anterior AMI (n=50). Appraisal of demographic, clinical and echocardiographic parameters of patients was undertaken. Biplane LVSI was calculated as an average of the short- and long-axis length in the 4- and 2-chamber apical views. Results A total of 50 TS patients (64.3±13.7 years, 18% men) were matched with 50 AMI (62.10±12.84 years, 74% men) patients. There was no significant difference in baseline cardiovascular risk factors other than diabetes mellitus (AMI 34% vs TS 17%, p = 0.034). There was also no difference in LV mass (p=0.10) or LVEF (p=0.52) between the two groups. Interestingly, there was a significant difference in mean LVSI between TS (0.60±0.06) vs AMI (0.52±0.07) (p<0.01) reflecting a more spherical shaped left ventricle in the acute TS group. Conclusions LVSI is reflective of geometric changes in the left ventricle and may be helpful as a rapid and reproducible diagnostic tool in differentiating between TS and AMI in the acute phase.

Electrocardiographic and Seasonal Patterns Allow Accurate Differentiation of Tako-Tsubo Cardiomyopathy from Acute Anterior Myocardial Infarction: Results of a Multicenter Study and Systematic Overview of Available Studies. Biomolecules 2019; 9:biom9020051.

Abstract
Background. Though several studies about prevalence, etiology, clinical characteristics, preceding events, clinical management, and outcome of Tako-Tsubo cardiomyopathy (TTC) exist, the current knowledge of TTC remains limited. Objective. In 2006, TTC was classified among the acquired forms of cardiomyopathy. On the basis of pathophysiological implications, we analyzed whether the presence of ST-segment elevation in lead -aVR (i.e., ST-segment depression in aVR) and the simultaneous absence of ST-segment elevation in lead V1 allow a reliable differentiation of TTC from acute anterior ST-segment elevation myocardial infarction (STEMI). A further investigative feature is the seasonal variation of TTC. Since acute cardiovascular events exhibit definite chronobiological patterns, various small studies have tried to evaluate whether this is also the case for TTC. Because results are conflicting, we also conducted a multicenter study and analyzed the findings in context with a systematic overview of available studies. Methods. We compared the ECG patterns of 115 patients with TTC, who were admitted to five large acute cardiac care centers associated with university hospitals in Southwestern Germany between January 2001 and June 2011, with those of 100 patients with acute anterior ST-segment elevation myocardial infarction (STEMI) treated in one of these centers. In addition, we performed a computer-assisted MEDLINE search of the literature from January 2000 to September 2011 and analyzed the chronobiological patterns of available TTC cases, including our TTC cohort. Results. Testing the predefined diagnostic criteria was superior to any other electrocardiographic finding and differentiated TTC from anterior STEMI with a sensitivity of 73%, a specificity of 84%, a positive predictive value of 63%, and a negative predictive value of 89%. Beyond that, the onset of TTC showed a clear variation as a function of season and month. While events occurred most frequently during summer (38.4%, p < 0.01), the event rate was the lowest in autumn (16.4%) and winter (21.9%). Chronobiological analyses on a monthly basis identified a significant annual rhythmic pattern in TTC, which peaked in August (11.9%; p < 0.01) and had its nadir in November (6.3%). Conclusions. Our data illustrate that the ST-segment changes in leads aVR and V1 represent a simple and accurate ECG criterion to differentiate TTC from anterior STEMI in patients who are admitted within 12 h of symptom onset. Similarly, the results of our seasonal analysis indicate a distinct chronobiological variation in TTC occurrence. TTC, thereby, differs from major acute cardiovascular diseases, especially acute myocardial infarction (AMI), which is characterized by winter peaks and troughs in summer. If these results are confirmed in large independent cohorts, they may yield diagnostic implications, changing the regular invasive AMI management in TTC patients.

Abstract
INTRODUCTION Takotsubo cardiomyopathy (TC) is an acquired cardiomyopathy affecting mostly postmenopausal women mimicking an acute coronary syndrome (ACS). TC clinical presentation involves chest pain, elevated cardiac enzymes, wall motion abnormalities and electrocardiographic changes, all of which share striking similarities to ACS. Areas covered: Differential diagnosis between TC and ACS can be complex since there are no reliable and widely-accepted electrocardiographic criteria and, at the moment, only coronary angiography can rule out one of the two diagnoses with good certainty. The present review will discuss the pros and cons of the ECG in TC, focusing on how the signal changes through the acute phase, the hospitalization, and after discharge. Specific information will be provided for each component of the ECG trace, and potential pitfalls will be highlighted, in order get to the core of this important unmet clinical issue. Expert commentary: There are at least several reasons why the ECG is still not considered a useful tool in differential diagnosis between TC and ACS. These include recent awareness of the syndrome, lack of evidence-based therapy, and, more importantly, a wide range of ECG features according to race, patient characteristics, wall motion abnormalities, triggers, and time from symptoms onset.

Abstract
Takotsubo cardiomyopathy is a syndrome mimicking an acute myocardial infarction in absence of obstructive epicardial coronary artery disease to explain the degree of the wall motion abnormalities. Typically more common in the elderly women, this condition is usually triggered by unexpected emotional or physical stress situations, and is associated with electrocardiogram abnormalities and slight elevation of cardiac biomarkers. The pathophysiological mechanism is not clear yet, but it is believed that a high circulating concentration of catecholamines causes an acute dysfunction of the coronary microcirculation and metabolism of cardiomyocytes, leading to a transient myocardial stunning. Typically, it presents with acute left ventricular systolic dysfunction that in most cases is completely resolved at short term. Recurrences are rare and it is thought that the long-term prognosis is good. We present here a review of the clinical features, pathophysiology and management of this enigmatic condition.

Abstract
The 12-lead electrocardiogram (ECG) is the important, initial examination for diagnosing acute coronary syndrome (ACS). In the traditional 12-lead ECG display, the precordial leads are displayed in their anatomically contiguous order, which makes it easy to understand the positional relationships between the precordial leads and the heart, but the limb leads are not. The "Cabrera sequence" displays the limb leads in an anatomically contiguous manner, which facilitates understanding of the positional relations between the limb leads and the heart, resulting in more rapid, easy, and accurate ECG interpretation than the traditional limb leads display. This review explores the clinical advantages of the Cabrera sequence as compared with the traditional limb leads display for the diagnosis of ACS. (Circ J 2016; 80: 1087-1096).

Abstract
Takotsubo cardiomyopathy (TTC) is characterized by transient left ventricular apical ballooning with the absence of coronary occlusion, which typically occurs in older women after emotional or physical stress. The pathophysiology of TTC is not well established, though several possible causes such as catecholamine cardiotoxicity, metabolic disturbance, coronary microvascular impairment and multivessel epicardial coronary artery spasm have been proposed. A number of diagnostic criteria have been suggested in the world and not unified as single, but the most common accepted one is Mayo Clinic proposed criteria. Since the clinical presentation of TTC is usually similar to acute coronary syndrome, differential diagnosis is essential to exclude other diseases and also for its treatment. Imaging modality including echocardiogram, angio CT and cardiac MRI, and lab tests for catecholamine, troponin T, creatine kinase MB and B-type natriuretic peptide can be useful to differentiate TTC from other diseases. Prognosis is generally favorable and in-hospital mortality is from 0% to within 10%.

Abstract
BACKGROUND Takotsubo cardiomyopathy (TC) can resemble acute anterior ST-elevation myocardial infarction. Most studies have examined TC in Asians and Caucasians (non-African Americans [AA]), while very few cases have been reported in AA. We aimed to assess the electrocardiographic features of TC in AA patients and compare them to non-AA TC patients. METHODS We retrospectively compared electrocardiograms of 52 AA and 47 non-AA patients diagnosed with TC. All patients met the modified Mayo Clinic criteria for the diagnosis of TC. Information collected included PR interval, QRS duration and amplitude, QT interval in milliseconds (msec) adjusted for heart rate (QTc), ST-segment deviation at the J point in limb and precordial leads (≥1 mm), ST elevation (≥1 mm), and T-wave inversion (≥0.5 mm). RESULTS T-wave inversion was more prevalent on presentation among AA patients (82% vs 48% in non-AA; P < 0.01), whereas ST depression was more common among non-AA (21% vs 7% in AA; P = 0.05). T-wave inversions in AA patients were frequent in both limb and precordial leads, whereas T-wave inversions in non-AA were limited to precordial leads. The average QTc upon presentation in AA was longer than non-AA (491 msec in AA vs 456 msec in non-AA; P < 0.01) as was the maximum average QTc during index hospitalization (527 msec in AA vs 497 msec in non-AA, P = 0.03). CONCLUSION In patients presenting with TC, AA patients more frequently present with diffuse T-wave inversions and a more prolonged QTc, whereas non-AA patients more often present with ST depressions. AA patients also more frequently present with T-wave inversions diffusely, whereas non-AA patients present with T-wave inversions more limited to the precordial leads.

Abstract
INTRODUCTION Several studies have investigated the ability of the twelve-lead electrocardiogram (ECG) to reliably distinguish Takotsubo cardiomyopathy (TC) from an acute anterior ST-segment elevation myocardial infarction (STEMI). In these studies, only ECG changes were required - ST-segment deviation and/or T-wave inversion - in TC whereas in acute anterior STEMI, ECGs had to meet STEMI criteria. In the majority of these studies, patients of both genders were used even though TC predominantly occurs in women. The aim of this study is to see whether TC can be distinguished from acute anterior STEMI in a predominantly female study population where all patients meet STEMI-criteria. METHODS Retrospective analysis of the ST-segment changes was done on the triage ECGs of 37 patients with TC (34 female) and was compared to the triage ECGs of 103 female patients with acute anterior STEMI. The latter group was divided into the following subgroups: 46 patients with proximal, 47 with mid and 10 with distal LAD occlusion. Three ST-segment based ECG features were investigated: (1) Existing criterion for differentiating anterior STEMI from TC: ST-segment depression >0.5mm in lead aVR+ST-segment elevation ≤1mm in lead V1, (2) frontal plane ST-vector and (3) mean amplitude of ST-segment deviation in each lead. RESULTS The existing ECG criterion was less accurate (76%) than in the original study (95%), with a large difference in sensitivity (26% vs. 91%). Only a frontal plane ST-vector of 60° could significantly distinguish TC from all acute anterior STEMI subgroups (p<0.01) with an overall diagnostic accuracy of 81%. The mean amplitude in inferior leads II and aVF was significantly higher for patients with TC compared to all patients with acute anterior STEMI (p<0.01 and p<0.05 respectively) and the mean amplitude in the precordial leads V1 and V2 was significantly lower compared to proximal and mid LAD occlusion (p<0.01). CONCLUSIONS Given the consequences of missing the diagnosis of an acute anterior STEMI the diagnostic accuracy of the ECG criteria investigated in this retrospective study were insufficient to reliably distinguish patients with TC from patients with an acute anterior STEMI. To definitely exclude the diagnosis of an acute anterior STEMI coronary angiography, which remains the gold standard, will need to be performed.

Takotsubo cardiomyopathy (TCM) is an unusual form of acute cardiomyopathy showing left ventricular apical ballooning. TCM can masquerade as ST elevation myocardial infarction (STEMI). TCM usually occurs following a variety of emotional stressors, but physical stressors can also trigger the condition, as highlighted by the present case. TCM can occur after an acute medical illness; therefore, physicians should be aware of this condition as a potential cause of inotrope-resistant hypotension. In patients with hypotension and moderate-to-severe left ventricular outflow tract (LVOT) obstruction, inotropic agents should be avoided, because they can worsen the degree of obstruction. Instead, beta-blockers are preferred, because they are capable of resolving the obstruction and consequently improve the haemodynamics.

Abstract
BACKGROUND Previous efforts to distinguish acute anterior ST-elevation myocardial infarction (anterior-STEMI) from various forms of takotsubo cardiomyopathy (TTC) by electrocardiography (ECG) have produced differing results. METHODS We performed a retrospective comparison of acute ECGs between 48 apical and 9 mid-ventricular TTC patients, with 96 anterior-STEMI patients. ECG was recorded in acute phase (<24h from onset of pain), and analyzed for ST-changes, negative T-waves, abnormal Q-waves and QT-interval duration. Time from onset of pain to ECG was gathered from patient records. RESULTS Anterior-STEMI patients had ST-elevation in lead V1 more frequently than apical (70% vs 15%, p<0.0001) or mid-ventricular TTC patients (70% vs 0%, p<0.0001), and higher ST-elevation amplitudes in leads V2-V5 (p<0.02). Lack of ST-elevation in lead V1 and ST-elevation amplitude <2mm in lead V2 distinguished TTC from anterior-STEMI patients with 63% sensitivity and 93% specificity, with 79% predictive value. CONCLUSIONS In patients with anterior ST-elevation and acute chest pain, lack of ST-elevation in lead V1 and ST-elevation amplitude <2mm in lead V2 suggests a TTC diagnosis. However, this criterion is not reliable enough in clinical practice to distinguish between TTC and anterior-STEMI patients.

Cardiac ⁹⁹mTc sestamibi SPECT and ¹⁸F FDG PET as viability markers in Takotsubo cardiomyopathy. Int J Cardiovasc Imaging 2014; 30:1407-16.

Abstract
In patients with heart failure (HF) due to coronary disease, a combined evaluation of perfusion and glucose metabolism by cardiac single photon emission computed tomography (SPECT)/positron emission tomography (PET) can be used to distinguish viable from non-viable myocardium, and current guidelines recommend cardiac SPECT and fluorodeoxyglucose (FDG) PET for viability assessment. Takotsubo cardiomyopathy (TTC) is a disease characterized by acute but reversible HF leaving no scarring. To explore how robust the semi-quantitative viability criteria used in cardiac SPECT and FDG PET stands their ground in a population with TTC. From 1 September 2009 to 1 October 2012, 24 patients suspected of TTC were enrolled in a multimodality cardiac imaging research project. Echocardiography, (99m)Tc SPECT, and (18)F FDG PET were performed during the acute admission and at follow-up 4 months later. Nineteen patients had a final diagnosis of TTC consistent with Mayo Clinic Diagnostic Criteria. Three of these patients were excluded from further analysis, since wall motion abnormalities were not persistent at the time of nuclear imaging. The remaining sixteen patients exhibited a distinct pattern with HF, "apical ballooning" and a perfusion-metabolism defect in the midventricular/apical region. When viability criteria were applied, they identified significant scarring/limited hibernation in the akinetic part of the left ventricle. However, full recovery was found in all TTC patients on follow-up. Using the current guideline-endorsed viability criteria for semiquantitative cardiac SPECT and FDG PET, these modalities failed to demonstrate the presence of viability in the acute state of TTC.

Abstract
Takotsubo cardiomyopathy (TC) is a recently recognized novel cardiac syndrome characterized by transient left ventricular dysfunction without obstructive coronary disease, electrocardiographic (ECG) changes (ST-segment elevation and/or negative T wave) or elevated cardiac enzymes. Because the clinical features and ECG findings of TC mimic those of anterior acute myocardial infarction (AMI) with occlusion of the left anterior descending coronary artery, differential diagnosis has an important role in selecting the most appropriate treatment strategy. Especially in the acute phase, differential diagnosis is essential for deciding whether reperfusion therapy is required. Although it has been suggested that ECG does not allow reliable differentiation between TC and anterior AMI, several ECG criteria distinguishing TC from anterior AMI have been proposed. In this review, we discuss ECG findings of TC, especially in the acute phase, compare them with those of anterior AMI, and identify ECG features that may facilitate early recognition of this disease.

Abstract
Takotsubo cardiomyopathy is a disorder characterized by left ventricular apical ballooning and electrocardiographic changes in the absence of coronary artery disease. While reversible in many cases, the mechanism of this disorder remains unclear. The most frequent clinical symptoms of takotsubo cardiomyopathy on admission are chest pain and dyspnea, resembling acute myocardial infarction. Here, we describe two cases of takotsubo cardiomyopathy without chest pain or dyspnea in patients on maintenance hemodialysis. The asymptomatic nature of these two cases may be due to the patients being on hemodialysis. Periodic electrocardiograms (ECG) may be helpful in screening this population for asymptomatic takotsubo cardiomyopathy and in evaluating its incidence.

Abstract
BACKGROUND AND OBJECTIVES Currently, there are no specific diagnostic electrocardiogram (ECG) signs for Takotsubo syndrome (TTS) to differentiate it from acute coronary syndromes (ACS). Myocardial oedema has been detected by cardiac magnetic resonance imaging in patients with TTS. Recently it has been postulated that myocardial oedema may be the cause of low QRS voltage (LQRSV) in the admission ECG and attenuation of the amplitude of the QRS complexes (AAQRS) in serial ECGs, noted in a few published cases of patients with TTS. The objective of this study was to evaluate whether the admission ECG of patients with documented TTS reveals LQRSV and whether AAQRS is found when serial ECGs are compared in such patients. METHODS This study evaluated the prevalence of LQRSV in the admission ECG and AAQRS in serial ECGs in patients with TTS. ECGs of 368 patients with TTS from published reports in the international literature were evaluated for LQRSV (≤5 mm in limb leads and/or ≤10 mm in precordial leads) and AAQRS in serial ECGs. RESULTS LQRSV was seen in 91.5% of 200 patients with TTS and one ECG, with a distribution of 49.0, 42.8, 51.0, 52.0, and 46.9%, in lead aVR, and inferior, anterior, lateral, and high lateral ECG lead groups, respectively. AAQRS was seen in 93.5% of 168 patients with TTS and two or more ECGs, with a distribution of 78.3, 74.5, 60.1, 70.7, and 74.5% in lead aVR, and inferior, anterior, lateral, and high lateral ECG lead groups, respectively. CONCLUSIONS LQRSV and AAQRS are highly prevalent ECG signs in patients with TTS, and should be useful in aiding in its diagnosis and differentiation from ACS, on first contact with the patient on admission to the hospital, and the ensuing 24 hours, in conjunction with echocardiography and coronary arteriography.

Abstract
A 68-year-old woman was admitted to our hospital due to sudden onset of dyspnea. On admission, electrocardiogram (ECG) showed T-wave inversion and QRS prolongation (120 msec) that were not found in her previous ECG. Chest X-ray showed pulmonary edema and cardiac enlargement. Left ventriculogram showed akinesis of the left ventricle except in the basal region. No significant coronary stenosis was found on angiogram. She was diagnosed as having tako-tsubo cardiomyopathy complicated by QRS prolongation. Intraaortic balloon pumping (IABP) was subsequently initiated for the treatment of acute heart failure. QRS prolongation was resolved immediately after the initiation of IABP, and left ventricular dysfunction was resolved within 9 days. She was discharged 14 days later.

Abstract
BACKGROUND In both takotsubo cardiomyopathy (TC) and reperfused anterior acute myocardial infarction (AMI), negative T waves commonly appear on the ECG in the subacute phase. This study aimed to clarify the ECG differences between these diseases. METHODS AND RESULTS We compared the ECGs with the greatest amplitude of negative T wave from 34 patients with TC and 237 patients with a first reperfused anterior AMI who were admitted within 6 h of symptom onset and who had no abnormal Q-waves on discharge ECG. Time from symptom onset to recording the ECG did not differ between TC and anterior AMI (2.4 ± 1.5 vs. 2.1 ± 2.0 days, P = 0.48). TC was associated with a greater maximal amplitude of negative T wave (1.00 ± 0.44 vs. 0.79 ± 0.46 mV, P = 0.044), and a greater number of leads with negative T waves (9.5 ± 1.0 vs. 6.0 ± 2.1, P<0.001). Negative T waves were consistently observed in leads -aV(R) and V(4-6), whereas negative T waves were rare in lead V(1) in TC. Negative T waves in lead -aV(R) (ie, positive T waves in lead aV(R)) and no negative T waves in lead V(1) identified TC with 94% sensitivity and 95% specificity, representing the highest diagnostic accuracy. CONCLUSIONS During the subacute phase, deeper negative T waves were more frequently and broadly distributed, particularly around leads facing the apical region, in TC than in reperfused anterior AMI.

Abstract
Stress cardiomyopathy is characterised by reversible left ventricular dysfunction. It simulates an acute coronary syndrome (ACS), presenting with precordial pain or dyspnoea, changes of the ST segment, T wave, or QTc interval on electrocardiogram, and raised cardiac enzymes. Typical findings are disturbances of segmental contractility (apical hypokinesia or akinesia), with normal epicardial coronary arteries. The true prevalence is unknown, as the syndrome may be under-diagnosed; it is more common in postmenopausal women. There is usually a trigger in the form of physical or psychological stress. The electrocardiographic, echocardiographic, and ventriculographic changes resolve spontaneously over a variable period of time (from days to months). There are a number of pathophysiological theories, none of which has been shown to be definitive, suggesting that all of them may be involved to some extent. The prognosis is generally favourable, and recurrence is very rare.

Abstract
Several studies have examined the ability of electrocardiography to differentiate between takotsubo cardiomyopathy (TC) and anterior wall acute ST-segment elevation myocardial infarction (AA-STEMI). In those studies, the magnitude of ST-segment elevation was not measured at the J point. The American Heart Association, American College of Cardiology Foundation, and Heart Rhythm Society guidelines recommend that the magnitude of ST-segment elevation should be measured at the J point. Accordingly, the aim of this study was to retrospectively examine whether electrocardiography, using the magnitude of ST-segment elevation measured at the J point, could differentiate 62 patients with TC from 280 with AA-STEMI. Patients with AA-STEMI were divided into following subgroups: 140 with left anterior descending coronary artery occlusions proximal to the first diagonal branch (AA-STEMI-P), 120 with left anterior descending occlusions distal to the first diagonal branch and proximal to the second diagonal branch (AA-STEMI-M), and 20 with left anterior descending occlusions distal to the second diagonal branch (AA-STEMI-D). TC had a much lower prevalence of ST-segment elevation ≥1 mm in lead V(1) (19.4%) compared to AA-STEMI (80.4%, p <0.01), AA-STEMI-P (80.7%, p <0.01), AA-STEMI-M (80%, p <0.01), and AA-STEMI-D (80%, p <0.01). ST-segment elevation ≥1 mm in ≥1 of leads V(3) to V(5) without ST-segment elevation ≥1 mm in lead V(1) identified TC with sensitivity of 74.2% and specificity of 80.6%. Furthermore, this criterion could differentiate TC from each AA-STEMI subgroup, with similar diagnostic values. In conclusion, using the magnitude of ST-segment elevation measured at the J point, a new electrocardiographic criterion is proposed with an acceptable ability to differentiate TC from AA-STEMI.

Abstract
AIMS Takotsubo cardiomyopathy (TC) or the apical ballooning syndrome is a reversible cardiomyopathy mimicking acute myocardial infarction (AMI). Although malignant arrhythmia is considered less likely to occur in TC than with AMI, sporadic reports of malignant arrhythmia with TC, however, have been reported. We reviewed the medical literature on TC and arrhythmias and describe in the summary the reported findings and discuss possible specific scenarios where arrhythmia may be more likely in patients with TC. METHODS AND RESULTS Articles were identified on PubMed using the MeSH terms 'Takotsubo Cardiomyopathy' or 'Apical Ballooning Syndrome'. Seventy-four unique case series with five or more TC patients were identified, with a cumulative total of 1876 cases. Twelve series (242 cases) were excluded because Mayo criteria were not met. Twenty-five series (816 cases, 43.5%) reported on arrhythmia and were included in the analysis. CONCLUSION Areas for further prospective study include the duration and mechanism of residual risk and optimal risk stratification and modification. The current state of evidence would support beta-blockers in the acute setting to control tachyarrhythmia, although there is little evidence to support their use beyond convalescence when used for this indication alone. Those in heart failure and cardiogenic shock should be managed with established evidence-based therapies for these conditions. The use of internal defibrillators in TC requires consideration only on a case-by-case basis.

Abstract
Takotsubo cardiomyopathy (TCM) is usually characterized by transient left ventricular apical ballooning. Due to the clinical symptoms which include chest pain, electrocardiographic changes, and elevated myocardial markers, Takotsubo cardiomyopathy is frequently mimicking ST-elevation myocardial infarction in the absence of a significant coronary artery disease. Otherwise an acute occlusion of the left anterior descending coronary artery can produce a typical Takotsubo contraction pattern. ST-elevation myocardial infarction (STEMI) is frequently associated with emotional stress, but to date no cases of STEMI triggering TCM have been reported. We describe a case of a female patient with inferior ST-elevation myocardial infarction complicated by TCM.

Abstract
The transient left ventricular apical ballooning syndrome or takotsubo-like left ventricular dysfunction refers to the ventricular morphological features present in the heart of these patients. It resembles the Japanese Takotsubo, which means a "fishing pot for trapping octopuses". This syndrome is characterized by transient left ventricular dysfunction, electrocardiographic changes and minimal release of myocardial enzymes that mimic acute anterior myocardial infarction, in patients without angiographic coronary artery disease. Several pathophysiological mechanisms have been proposed to explain it; however the precise aetiology remains unknown. This condition is transient and has a good prognosis, however Takotsubo cardiomyopathy as a new entity of acute heart failure, should be noted and thought of as a cause of sudden cardiac death. Its proper diagnosis and management greatly depends on our initial suspicion.

A new ECG criterion to identify takotsubo cardiomyopathy from anterior myocardial infarction: role of inferior leads. Heart Vessels 2009; 24:124-30.

Abstract
With the exception of contrast-enhanced cardiovascular magnetic resonance imaging, clear distinction of takotsubo cardiomyopathy from anterior wall myocardial infarction cannot be achieved currently by simple and noninvasive tests. The aim of this study was to examine the role of inferior ECG leads in distinguishing these two conditions. From January 2004 to June 2006, eight female patients suffering from takotsubo cardiomyopathy were identified by the Mayo Clinic criteria. The clinical and ECG features were compared with 27 consecutive sex- and age-matched patients with anterior wall myocardial infarction admitted to the Coronary Care Unit within the same period. The observed ECG features were then verified with that of 62 published cases of takotsubo cardiomyopathy. Takotsubo cardiomyopathy patients had similar left ventricular ejection fraction (35.0% +/- 5.7% vs 38.2% +/- 6.4%, P = 0.829), lower peak creatinine kinase level (461 +/- 330 U/l vs 2723 +/- 1826 U/l, P = 0.020), more ST-segment elevation in the inferior leads (50% vs 7.4%, P = 0.016), and virtually no ST-segment depression in inferior leads (0% vs 48.2%, P = 0.015) compared with patients who had anterior wall myocardial infarction. ST-segment elevation of >or=1.0 mm in lead II had 62.5% sensitivity and 92.6% specificity in detecting takotsubo cardiomyopathy. The observed ECG characteristics were comparable with those in the literature. In patients who present with anterior wall myocardial infarction, the absence of ST-segment depression or ST-segment elevation in inferior leads, especially if the ST-segment in lead II >or= III, is highly suggestive of takotsubo cardiomyopathy.

Abstract
Takotsubo cardiomyopathy (TC) is characterized by transient, often severe, left ventricular dysfunction and electrocardiographic changes that might mimic acute myocardial infarction in the absence of significant obstructive coronary artery disease. It is often encountered in elderly women after physical or emotional stress. Excessive catecholamine stimulation, metabolic abnormalities, and microcirculatory dysfunction are thought to be responsible for the manifestations of this disorder. This comprehensive review summarizes relevant published data, atypical presentations, pathophysiology, and management strategy. It also includes a review of 789 patients with TC including nine illustrative cases encountered at our institution.

Abstract
BACKGROUND Transient apical ballooning syndrome (TABS) or Takotsubo cardiomyopathy mimics acute ST-elevation myocardial infarction, but is considered to have a good prognosis with only moderate elevation of myocardial enzymes and full recovery of left ventricular function. Although it is increasingly reported, its exact incidence, clinical presentation, and prognosis in non-Asian populations remain largely unknown. OBJECTIVE To describe the clinical characteristics and long-term follow-up of patients who presented with TABS at our institution over a 3 year-period. METHODS Patients were retrospectively retrieved from our local database. Patient charts were carefully reviewed and the diagnosis of TABS was based on the Mayo Clinic diagnostic criteria. Moreover, psychosocial stress or gastrointestinal disease was recorded. RESULTS During the study period, 13,715 coronary angiographies were performed at our institution, including 2459 patients presenting with an acute coronary syndrome (ACS). Forty-one TABS were diagnosed, which represents an incidence of 1.7% of ACS-patients and 0.3% of all coronary angiographies performed, respectively. Mean age was 65 years, with 85% women. Clinical presentations included chest pain, dyspnoea, and cardiogenic shock. A preceding psychological or physical condition perceived as "stress" was reported in 61%. At a mean follow-up of 675+/-288 days, none of the patients died of cardiac causes, but two patients had a recurrence of symptoms. CONCLUSIONS This is the largest cohort of TABS patients reported out of Europe so far. The good overall prognosis and low likelihood of recurrence were confirmed.

Abstract
Takotsubo cardiomyopathy (transient apical ballooning of the left ventricle) is a recently described and often underdiagnosed entity. The syndrome is observed predominately in postmenopausal women and the clinical signs are similar to those of an acute anterior myocardial infarction. In most of the reported cases an emotional or physical stress event has been identified as a trigger, and perioperative stress has been suggested as the trigger in some of these cases. Outcome is favorable with the right treatment, though recurrences are possible. We report the anesthetic management of a 79-year-old woman with a previously diagnosed episode of Takotsubo cardiomyopathy, who was admitted to our hospital for total hip replacement. Care was taken to provide proper preoperative sedation before provision of hyperbaric spinal anesthesia, followed by sedation with intravenous propofol. Surgery and the early postoperative period were uneventful. We believe that minimizing perioperative anxiety should be a priority in these patients due to the possibility that a catecholamine discharge might trigger an episode of Takotsubo cardiomyopathy.

Abstract
Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy, left ventricular apical ballooning syndrome, and broken heart syndrome, is a clinical entity first described in the early 1990s in Japan and now receiving increased attention in the United States. The clinical features include an onset of chest pain mimicking that of an acute myocardial infarction, electrocardiogram changes similar to those of an acute myocardial infarction, normal coronary arteries on cardiac catheterization, and a signature appearance on echocardiogram. Takotsubo cardiomyopathy results in a significantly decreased ejection fraction that, as long as the patient receives appropriate hemodynamic support, typically undergoes spontaneous reversal. This article describes the history, clinical presentation, and management strategies for Takotsubo cardiomyopathy and provides a case study.
