Abstract
BACKGROUND Takotsubo syndrome (TTS) is a cardiac disorder that mimics acute coronary syndrome at presentation. While previous studies have demonstrated a relationship between body mass index (BMI) and outcomes in acute coronary syndrome, few have examined its relationship with TTS. METHODS Using the Japanese Diagnosis Procedure Combination database, we retrospectively identified 14,551 patients admitted for TTS between 2010 and 2021. By applying multivariable regressions with restricted cubic splines, we examined the association between BMI and in-hospital mortality after adjusting for potential confounders. RESULTS Mean BMI was 21.1 kg/m2, classifying patients into severe underweight (<16.0 kg/m2, 7.1%), mild/moderate underweight (16.0-18.4 kg/m2, 18.3%), normal weight (18.5-22.9 kg/m2, 46.8%), overweight (23.0-27.4 kg/m2, 22.2%), and obese (≥27.5 kg/m2, 5.6%) groups. Patients with severe or mild/moderate underweight were older and had a higher prevalence of impaired physical activity, malignancy, chronic pulmonary disease, and pneumonia. In-hospital mortality was the highest (9.4%) in the severe underweight group, followed by the mild/moderate underweight group (5.4%), with the lowest being in the obese group (2.1%). Severe underweight (adjusted odds ratio = 2.05; 95% confidence interval [CI] = 1.54-2.73) and mild/moderate underweight (1.26; 95% CI = 1.01-1.57) were significantly associated with higher mortality compared with normal weight, while no significant association was noted with obesity. A nonlinear association between continuous BMI and mortality was observed, with mortality increasing when BMI decreased <20.0 kg/m2 but nearly plateauing in BMI >20.0 kg/m2. CONCLUSIONS The present nationwide analysis demonstrated a nonlinear association between BMI and in-hospital mortality of TTS. BMI is an easily available and clinically relevant marker for the risk stratification of TTS.

Abstract
We discuss a case of a 42-year-old female who was admitted for chronic intractable lower back pain requiring elective spinal surgery. Postoperatively, she experienced chest pressure and abdominal pain with a notable elevation in cardiac markers. A cardiac catheterization and left ventriculogram revealed normal coronary arteries and basal anterolateral hypokinesis, with the normal movement of the distal segment of the anterior wall. A rare variant of stress cardiomyopathy was diagnosed.

Abstract
BackgroundTakotsubo syndrome is an acute cardiac condition involving sudden, transient apical ballooning of the left ventricle of the heart that may be triggered by emotional stress and some non-cardiac conditions. Its diagnosis is based on clinical presentation, electrocardiogram, cardiac imaging and biomarkers.Case SummaryHere, we present a novel and original case report of a patient presenting very soon in the post-partum period with an unusual form of Takotsubo syndrome without clinical symptoms of cardiac disease and accompanied by HELLP syndrome. The overall dynamics of the changes in troponin I, troponin T and NT-proBNP levels after delivery were generally similar, but the amount of troponin I was much greater than that of troponin T and troponin I was already elevated before delivery. NT-proBNP levels peaked around the same time as the troponins and the peak concentration was within the same range as that of troponin I.DiscussionOur findings indicate that assaying circulating cardiac biomarkers, especially troponin I and NT-proBNP, may be a useful complement to non-invasive cardiac imaging including transthoracic echocardiography and cardiovascular magnetic resonance imaging, in the diagnosis of Takotsubo syndrome. They illustrate the importance of cardiac biomarkers in assisting diagnosis of this disease.

Abstract
Takotsubo cardiomyopathy (TCM), characterized by reversible ventricular dysfunction, has similar mortality to acute coronary syndrome. With the growing interest in the diagnosis of and interventions for TCM, many risk factors had been found to affect the prognosis of TCM patients, such as age, sex, and pre-existing diseases. Because of the incomplete understanding of the pathophysiologic mechanism in TCM, evidence-based medical therapy for this condition is lacking. Early intervention on risk factors may improve the outcomes of TCM. In this review, we sought to provide up-to-date evidence on risk factors and medical therapies that affect TCM outcome. We found that male sex, physical triggers, and certain comorbidities such as chronic kidney disease, malignant disease, higher body mass index, sepsis, chronic obstructive pulmonary disease, and anaemia were associated with poor TCM prognosis. In contrast, race, hyperlipidaemia, diabetes mellitus, and mood disorders were not clearly associated with TCM prognosis. We also reviewed the effect of medical therapies on TCM outcome, including angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, β-blockers, calcium channel blockers, and statins. The evidence that these medications confer a survival benefit on TCM patients is limited. Understanding these prognostic factors could help develop risk-stratification tools for TCM and establish effective prevention and interventions for this not-so-benign condition. Further multicentre clinical studies with large samples and meta-analyses of findings from previous studies are needed to address the inconsistent findings among the many potential risk factors for TCM.

Prognostic value of texture analysis from cardiac magnetic resonance imaging in patients with Takotsubo syndrome: a machine learning based proof-of-principle approach. Sci Rep 2020; 10:20537.

Abstract
Cardiac magnetic resonance (CMR) imaging has become an important technique for non-invasive diagnosis of takotsubo syndrome (TTS). The long-term prognostic value of CMR imaging in TTS has not been fully elucidated yet. This study sought to evaluate the prognostic value of texture analysis (TA) based on CMR images in patients with TTS using machine learning. In this multicenter study (InterTAK Registry), we investigated CMR imaging data of 58 patients (56 women, mean age 68 ± 12 years) with TTS. CMR imaging was performed in the acute to subacute phase (median time after symptom onset 4 days) of TTS. TA of the left ventricle was performed using free-hand regions-of-interest in short axis late gadolinium-enhanced and on T2-weighted (T2w) images. A total of 608 TA features adding the parameters age, gender, and body mass index were included. Dimension reduction was performed removing TA features with poor intra-class correlation coefficients (ICC ≤ 0.6) and those being redundant (correlation matrix with Pearson correlation coefficient r > 0.8). Five common machine-learning classifiers (artificial neural network Multilayer Perceptron, decision tree J48, NaïveBayes, RandomForest, and Sequential Minimal Optimization) with tenfold cross-validation were applied to assess 5-year outcome including major adverse cardiac and cerebrovascular events (MACCE). Dimension reduction yielded 10 TA features carrying prognostic information, which were all based on T2w images. The NaïveBayes machine learning classifier showed overall best performance with a sensitivity of 82.9% (confidence interval (CI) 80-86.2), specificity of 83.7% (CI 75.7-92), and an area-under-the receiver operating characteristics curve of 0.88 (CI 0.83-0.92). This proof-of-principle study is the first to identify unique T2w-derived TA features that predict long-term outcome in patients with TTS. These features might serve as imaging prognostic biomarkers in TTS patients.

Arch Med Sci 2020; 16:282-288. [PMID: 32190137 PMCID: PMC7069448 DOI: 10.5114/aoms.2019.87082] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2019] [Accepted: 06/02/2019] [Indexed: 02/08/2023] Open
Abstract
INTRODUCTION The clinical courses of takotsubo syndrome (TS) and of acute coronary syndromes (ACS) seem to be very similar. However, there is limited knowledge about risk factors of poor outcomes. Low body mass index worsens the prognosis of patients with cardiovascular diseases, especially those undergoing surgical treatment. The aim of the study was to evaluate the influence of the body mass index (BMI) on the prognosis in patients diagnosed with TS. MATERIAL AND METHODS Eighty patients aged 15-89 (mean: 67.9 years), 74 women and 6 men with TS diagnosis according to Mayo Clinic diagnostic criteria were divided into 3 groups: low body mass (BMI < 18.5 kg/m2), normal body mass (18.5 ≥ BMI < 25 kg/m2) and excessive body mass (BMI ≥ 25 kg/m2). RESULTS Patients with low BMI were older, but with less prevalent risk factors such as hypertension, hypercholesterolemia and positive family history of coronary artery disease and more frequent risk factors such as cigarette smoking, chronic obstructive pulmonary disease (COPD), depressive and anxiety disorders as well as malignancy. They also had higher haemoglobin, lower troponin, creatine kinase, C-reactive protein and lipid fractions. The highest annual, 3-year and 5-year mortality was observed in the group with BMI < 18.5 kg/m2. None of the patients with low BMI survived the 5-year follow-up period (100% vs. 25% vs. 15.2%; p < 0.0001). In group III, mortality among overweight patients (25 ≥ BMI < 30 kg/m2) was 8.3%, and in obese people (BMI ≥ 30 kg/m2) 1 out 5 patients died during follow-up. CONCLUSIONS The majority of typical cardiovascular risk factors are less frequently observed in patients with TS and low body mass. Early prognosis for TS patients and low BMI is relatively favourable, whereas the 5-year follow-up is associated with extremely high mortality. Overweight patients have the best prognosis in the long-term follow-up.

Abstract
Stress-induced cardiomyopathy (SIC) results from a profound catecholaminergic surge during strong emotional or physical stress. SIC is characterized by acute left ventricular apex hypokinesia, in the absence of coronary arteries occlusion, and can lead to arrhythmias and acute heart failure. Although, most SIC patients recover, the process could be slow, and recurrence or death may occur. Despite that the SIC common denominator is a large catecholamine discharge, the pathophysiological mechanism is incompletely understood. It is thought that catecholamines have direct cytotoxicity on apical ventricular myocytes (VM), which have the highest β-adrenergic receptors density, and whose overstimulation might cause acute Ca2+ overload and oxidative stress, causing death in some VM and stunning others. Rodents receiving acute isoproterenol (ISO) overdose (OV) mimic SIC development, however, they have not been used to simultaneously assess Ca2+ handling and contractility status in isolated VM, which might explain ventricular hypokinesia. Therefore, treating rats with a single ISO-OV (67 mg/kg body weight), we sought out to characterize, with confocal imaging, Ca2+ and shortening dynamics in Fluo-4-loaded VM, during the early (1-5 days) and late post-acute phases (15 days). We found that ISO-OV VM showed contractile dysfunction; blunted shortening with slower force development and relaxation. These correlated with Ca2+ mishandling; blunted Ca2+ transient, with slower time to peak and SR Ca2+ recovery. SR Ca2+ content was low, nevertheless, diastolic Ca2+ sparks were more frequent, and their duration increased. Contractility and Ca2+ dysfunction aggravated or remained altered over time, explaining slow recovery. We conclude that diminished VM contractility is the main determinant of ISO-OV hypokinesia and is mostly related to Ca2+ mishandling.

Abstract
Background Left ventricular (LV) recovery in takotsubo syndrome (TTS) occurs over a wide‐ranging interval, varying from hours to weeks. We sought to investigate the clinical predictors and prognostic impact of recovery time for TTS patients. Methods and Results TTS patients from the International Takotsubo Registry were included in this study. Cut‐off for early LV recovery was determined to be 10 days after the acute event. Multivariable logistic regression was used to assess factors associated with the absence of early recovery. In‐hospital outcomes and 1‐year mortality were compared for patients with versus without early recovery. We analyzed 406 patients with comprehensive and serial imaging data regarding time to recovery. Of these, 191 (47.0%) had early LV recovery and 215 (53.0%) demonstrated late LV improvement. Patients without early recovery were more often male (12.6% versus 5.2%; P=0.011) and presented more frequently with typical TTS (76.3% versus 67.0%, P=0.040). Cardiac and inflammatory markers were higher in patients without early recovery than in those with early recovery. Patients without early recovery showed unfavorable 1‐year outcome compared with patients with early recovery (P=0.003). On multiple logistic regression, male sex, LV ejection fraction <45%, and acute neurologic disorders were associated with the absence of early recovery. Conclusions TTS patients without early LV recovery have different clinical characteristics and less favorable 1‐year outcome compared with patients with early recovery. The factors associated with the absence of early recovery included male sex, reduced LV ejection fraction, and acute neurologic events. Clinical Trial Registration URL: http://www.clinicaltrials.gov.

The cardioprotective effects of icariin on the isoprenaline-induced takotsubo-like rat model: Involvement of reactive oxygen species and the TLR4/NF-κB signaling pathway. Int Immunopharmacol 2019; 74:105733. [PMID: 31288151 DOI: 10.1016/j.intimp.2019.105733] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2019] [Revised: 06/26/2019] [Accepted: 06/29/2019] [Indexed: 12/22/2022]
Abstract
INTRODUCTION Takotsubo syndrome (TS) is an acute cardiac syndrome that mimics acute coronary syndrome (ACS) but lacks coronary obstruction and is associated with sudden physical or psychiatric episodes. Several hypotheses have been proposed for the TS mechanism, but the precise cause of this syndrome remains poorly known. Recent studies noted TS patients with acute endogenous catecholamine discharge, which could trigger an oxidative stress response and inflammatory action. METHODS A single dose of the selective β-adrenergic agonist isoprenaline (ISO) was used to induce a takotsubo-like (TS-like) model. Different icariin or metoprolol doses were supplied as cardioprotective agents by intragastric administration (IG), and lipopolysaccharides (LPS) were assessed to investigate the possible mechanism of action of icariin. Transthoracic echocardiography was used to study cardiac function and morphology. The amounts of intracellular lipids and myocardial fibrosis, which represent the degree of cardiac impairment, were assessed by histological analysis. Real-time polymerase chain reaction (RT-PCR) was performed to analyze a variety of anti-oxidant elements and inflammatory factors, and Western blotting was conducted to analyze the expression of signaling pathway proteins involved in the development of TS. RESULTS The TS-like incidence in rats was lowest with icariin precondition at 2-h post-ISO administration, and both the left ventricular ejection fraction (LVEF) and ejection volume per minute were higher than those of the other groups. However, LPS administration increased the incidence of TS and aggravated cardiac impairment. Moreover, ISO significantly increased the levels of both reactive oxygen species (ROS) and TLR4/NF-κB signaling pathway proteins compared to those of the Sha-group, whereas icariin remarkably decreased the ROS levels and increased anti-oxidant element expression while reducing pro-inflammatory factor secretion and suppressing TLR4/NF-κB signaling pathway protein expression. However, the cardioprotective effect of icariin was significantly weakened by combining treatment with LPS. CONCLUSION Icariin prevented ISO-induced TS-like cardiac dysfunction in rats. The effects were induced mainly through maintenance of the dynamic balance of the ROS system, promotion of anti-oxidant element activity, and suppression of TLR4/NF-κB signaling pathway protein expression. Furthermore, the ability of icariin to increase anti-inflammatory and reduce pro-inflammatory factor secretion may be involved in the protective process.

Abstract
Stress cardiomyopathy is an acute reversible heart failure syndrome initially believed to represent a benign condition due to its self-limiting clinical course, but now recognized to be associated with a non-negligible rate of serious complications such as ventricular arrhythmias, systemic thromboembolism, and cardiogenic shock. Due to an increased awareness and recognition, the incidence of stress cardiomyopathy has been rising (15-30 cases per 100,000 per year), although the true incidence is unknown as the condition is likely underdiagnosed. Stress cardiomyopathy represents a form of neurocardiogenic myocardial stunning, and while the link between the brain and the heart is established, the exact pathophysiological mechanisms remain unclear. We herein review the proposed risk factors and triggers for the syndrome and discuss a practical approach to diagnosis and treatment of the patients with stress cardiomyopathy, highlighting potential challenges and unresolved questions.

Abstract
Takotsubo cardiomyopathy (TTC) is a transient systolic dysfunction of the left ventricle which is usually seen in elderly women, often following a physical or emotional stressful event. Little is known about the prognostic factors affecting the recovery of systolic function. Thirty-six patients diagnosed with TTC from January 2006 to January 2017 at our hospital were included. Median time to recovery of ejection fraction (EF) was calculated to be 25 days. Early recovery of ejection fraction was defined as less than or equal to 25 days (group 1) and late recovery was defined as more than 25 days (group 2). Demographic and clinical factors were compared between the groups. Fifty percent patients had early recovery of EF with a mean time to recovery of 7.11 days and 50% had late recovery of ejection fraction with a mean time to recovery of 58.38 days. Younger age at presentation was associated with early recovery of systolic function (58.83 ± 2.7 years vs. 67.33 ± 2.7 years, p = 0 .032). Presence of an identifiable triggering event was associated with early recovery (83% in group 1 vs. 50% in group 2, p = 0.034). Generalized anxiety disorder was seen more commonly in the group with early recovery (78% in group 1 vs. 45% in group 2, p = 0.040). In conclusion, younger age, generalized anxiety disorder and presence of triggering event were seen more commonly in patients with early recovery of left ventricular systolic function in Takotsubo cardiomyopathy.

Abstract
Several therapeutic options are available for the treatment of the acute phase of stress cardiomyopathy, pharmacological (β-blockers, diuretics, anticoagulants, antiarrhythmics, noncatecholamine inotropics [levosimendan]), and nonpharmacological (intra-aortic balloon pumping, extracorporeal membrane oxygenation), according to the wide possible clinical presentation and course of the disease. However, there is a gap in evidence, and very few data come from randomized and adequately powered studies. Some evidence supports the use of β-blockers, in particular with a short half-life, in the case of left ventricular outflow tract obstruction, and angiotensin-converting enzyme inhibitors in secondary prevention. Future perspectives include the study of genetic basis of stress cardiomyopathy, role of miRNA and neurovegetative modulation. Randomized studies, however, are surely warranted.
