INTRODUCTION: Takotsubo syndrome (TS) is an acute cardiac condition that is often triggered by critical illness but that has rarely been studied in the intensive care unit (ICU) setting. The aim of this study was to (i) estimate the incidence of TS in a hemodynamically unstable ICU-population; (ii) identify predictors of TS in this population; (iii) study the impact of TS on prognosis and course of hospitalization. METHODS: Medical records from all patients admitted to our general ICU from 2012 to 2015 were analyzed...

L-Homoarginine (hArg) and guanidinoacetate (GAA) are produced from L-arginine (Arg) by the catalytic action of arginine:glycine amidinotransferase. Guanidinoacetate methyltransferase methylates GAA on its non-guanidine N atom to produce creatine. Arg and hArg are converted by nitric oxide synthase (NOS) to nitric oxide (NO). NO is oxidized to nitrite and nitrate which circulate in the blood and are excreted in the urine. Asymmetric dimethylarginine (ADMA), an NOS inhibitor, is widely accepted to be exclusively produced after asymmetric N (G)-methylation of Arg residues in proteins and their regular proteolysis...

Takotsubo syndrome (TTS) is characterized by acute left ventricular dysfunction, with a hospital-mortality rate similar to acute coronary syndrome (ACS). However, the aetiology of TTS is still unknown. In the present study, a multivariate pattern analysis using machine learning with multimodal magnetic resonance imaging (MRI) data of the human brain of TTS patients and age- and gender-matched healthy control subjects was performed. We found consistent structural and functional alterations in TTS patients compared to the control group...

Takotsubo cardiomyopathy (TCM) is a relatively recently recognised clinical entity. It frequently mimics acute coronary syndrome and is accompanied by reversible left ventricular apical ballooning in the absence of angiographically significant coronary artery stenosis. TCM is a reversible condition, and the prognosis is usually well. However, in rare instances, it can be associated with life-threatening arrhythmic complications. Herein, we report the case of a patient with TCM who developed complete atrioventricular block followed by QT prolongation and torsades de pointes...

Takotsubo cardiomyopathy (TTC) is associated with acute, reversible left ventricular (LV) dysfunction, while transient global amnesia (TGA) is a reversible disorder of the brain characterised by anterograde amnesia. We report an unusual case of TTC occurring concurrently in a patient with TGA, and propose that catecholamine surge induced cerebral venous congestion and cardiotoxicity is the shared aetiology that leads to the concurrent manifestation of these conditions. TTC and TGA are reversible disorders that can occur concurrently in a subset of patients due to a unifying aetiology, catecholamine excess, leading to pathophysiological changes within the brain and the myocardium...

A 24-year-old woman at 38 weeks of gestation with no past medical history was transferred to our hospital because of acute onset of severe dyspnea. Her conscious level was E4V2M5 on the Glasgow Coma Scale and she displayed stress cardiomyopathy (Takotsubo cardiomyopathy) with multiple organ failure. Intrauterine fetal death was confirmed. After immediate application of intubated ventilation, percutaneous cardiopulmonary support and hemodialysis, she was diagnosed with pheochromocytoma multisystem crisis. After multidisciplinary team discussion, surgical resection of the left pheochromocytoma was performed on the same day...

Pheochromocytoma (PHEO) and paraganglioma (PGL) (PPGL) may cause acute Takotsubo-like catecholamine cardiomyopathy (TLC). OBJECTIVE: To determine the prevalence and clinical presentation of TLC in a large cohort of patients with PPGL. METHODS: We reviewed retrospectively the records of consecutive patients with PPGL investigated in our center from 1995 to 2016. We collected clinical and paraclinical data of patients that had TLC in this cohort. We performed a literature review of cases of TTC-related to PPGL described previously from 1990-2015...

Takotsubo cardiomyopathy (TC) is a life-threatening syndrome with ambiguous pathophysiology. The interdependency between heart failure and kidney failure (KF) is well established, but the influence of KF on TC outcome is not known. This single-center cohort from January 2003 to September 2015 consisted of 114 consecutive patients with TC. They were divided into 2 groups according to the presence (n = 32, 29.6%) or absence (n = 76, 70.3%) of KF. The end point of this retrospective study was a composite of in-hospital events, all-cause mortality, rehospitalization due to heart failure, stroke, and recurrence of TC (mean follow-up: 5 years)...

BACKGROUND: Takotsubo cardiomyopathy is characterized by transient systolic dysfunction of the apical and mid segments of the left ventricle in the absence of obstructive coronary artery disease. Intraventricular thrombus formation is a rare complication of Takotsubo cardiomyopathy and current data almost exclusively consists of isolated case reports and a few case series. Here we describe a case of Takotsubo cardiomyopathy with formation of an apical thrombus within 24 h of symptom onset, which has been reported in the literature only once previously, to the best of our knowledge...

Takotsubo cardiomyopathy describes a sudden onset cardiomyopathy with acute impairment of left ventricular function and spontaneous resolution over time. Only a few cases of Takotsubo cardiomyopathy in childhood have been described. We report the case of a 12-year-old girl with repaired tetralogy of Fallot who experienced acute onset of left ventricular dysfunction without coronary arterial involvement, suggesting Takotsubo cardiomyopathy, during an interventional catheterization procedure. Cardiogenic shock necessitated mechanical circulatory support with extracorporeal membrane oxygenator for ten days and mechanical ventilation for 12 days...

A 70-year-old woman presented with progressive lower extremity weakness and heaviness accompanied with chest pain. Troponin T was elevated, and an echocardiogram showed a left ventricular ejection fraction of 30% and a hypokinetic left ventricular apex. Neurophysiologic testing was consistent with Guillain-Barré syndrome, which was treated with intravenous immunoglobulin therapy. Repeat echocardiogram showed an improved left ventricular ejection fraction and no left ventricular wall motion abnormalities. Takotsubo cardiomyopathy is a rare complication of Guillain-Barré syndrome; less than 10 cases have been reported...

Although most patients with takotsubo cardiomyopathy have a favorable outcome, complications are not uncommon. Recent studies have reported an increase in incidence of cardioembolic complications; however, the association between takotsubo cardiomyopathy and stroke, in particular thromboembolic cerebral infarction, remains unclear. We reported a 44-year-old woman who had a cerebral infarction resulting from takotsubo cardiomyopathy. She had felt chest discomfort a few days prior to infarction, and later developed left hemiparesis...

Among diverse triggering factors of stress-induced takotsubo cardiomyopathy (TC), a viral or bacterial infection is rarely observed. Sepsis is an exception, regardless of the etiologic pathogen, in which case an excess of catecholamines may result in acute left ventricular dysfunction. TC precipitated by Clostridium difficile infection (CDI) has been reported only in two patients so far. A CASE REPORT: The authors describe another case of TC triggered this time by recurrent C. difficile colitis which occurred in a 72-yearold female...

BACKGROUND: Patients with chest pain, elevated troponin, and unobstructed coronary disease present a clinical dilemma. The purpose of this study was to investigate the incremental diagnostic value of cardiovascular magnetic resonance (CMR) in a cohort of patients with suspected acute coronary syndrome (ACS) and unobstructed coronary arteries. RESULTS: Data files of patients meeting the inclusion criteria in two cardiology centres were searched and analysed. The inclusion criteria included: 1) thoracic pain suspected with ACS; 2) a significant increase in the high-sensitive Troponin T value; 3) ECG changes; 4) coronary arteries without any significant stenosis; 5) a CMR examination included in the diagnostic process; 6) an uncertain diagnosis before the CMR exam; and 7) the absence of known CMR and contrast media contraindications...

Takotsubo syndrome is an acute reversible heart failure syndrome triggered by physical or emotional stress, especially in postmenopausal women. Herein, we describe a case of a 31-year-old pacemaker dependent lady who presented with syncope after she was bereaved of her father. Electrocardiogram at admission revealed ventricular paced rhythm at 60/min, prolonged QT interval and frequent runs of torsades de pointes. Transthoracic echocardiogram and left ventriculogram revealed findings typical of Takotsubo syndrome...
