BACKGROUND: Prolonged QRS duration (pQRSd) on electrocardiogram (ECG) is a strong predictor of poor outcome in heart failure, myocardial infarction, and myocarditis, but it is unclear whether pQRSd also predicts poor outcomes of takotsubo cardiomyopathy (TC).Methods and Results:Between 1 January 2010 and 31 December 2012, we retrospectively enrolled 299 patients with TC (mean age, 73.5±11.7 years; 21.4% male) from the Tokyo CCU Network database, which consists of 71 cardiovascular centers in the metropolitan area...

BACKGROUND: The aim of this study was to determine the efficacy and safety of levosimendan in takotsubo cardiomyopathy (TC). METHODS: The study was conducted in a retrospective design and 42 consecutive patients were enrolled in 6 cardiovascular centers in Turkey. The records of TC patients having left ventricular ejection fraction (LVEF) ≤ 35% were examined at admission, discharge and recovery period including their clinical and echocardiographic data were recorded...

PURPOSE: To investigate changes in sympathetic activity, perfusion, and left ventricular (LV) functionality in takotsubo cardiomyopathy (TTC) patients from onset (T0) to post-onset conditions at 1 month (T1), 1-2 years (T2, T3). METHODS: Twenty-two patients (70 ± 11 years) underwent serial gated single photon emission tomography (G-SPECT) studies with (123)I-mIBG and (99m)Tc-Sestamibi. Statistics were performed using ANOVA/Sheffé post-hoc, correlation test, and receiver operating characteristic (ROC) curve analysis (p < 0...

Objective Left ventricular outflow tract (LVOT) obstruction is a complication in 15-25% of patients with Takotsubo cardiomyopathy and sometimes leads to catastrophic outcomes, such as cardiogenic shock or cardiac rupture. However, the underlying mechanisms have not been clarified. Methods and Results We experienced 22 cases of Takotsubo cardiomyopathy during 3 years, and 4 of these 22 cases were complicated with LVOT obstruction in the acute phase (mean age 79±5 years, 1 man, 21 women). The LVOT pressure gradient in the acute phase was 100±17 mmHg...

BACKGROUND: Pheochromocytoma, a rare catecholamine-producing tumor, might provoke stress-induced Takotsubo-like cardiomyopathy and severe cardiogenic shock. Because venoarterial-extracorporeal membrane oxygenation (VA-ECMO) rescue of pheochromocytoma-induced refractory cardiogenic shock has rarely been reported, we reviewed our ICU patients' presentations and outcomes. METHODS: All pheochromocytoma-induced refractory cardiogenic shock cases managed with VA-ECMO (January 2007-March 2015) were prospectively included and reviewed...

A 61-year-old woman was admitted to our hospital for speech disturbance and mild consciousness impairment. Despite the absence of seizures or loss of consciousness, electroencephalographic abnormalities were observed, and the cerebral blood flow scintigraphy revealed an increase in cerebral blood flow in the left temporal lobe. These findings suggested a diagnosis of non-convulsive status epilepticus. On the third day, a twelve-lead electrocardiogram showed a negative T-wave in I, II, aVf, and V2-6. Moreover, a transthoracic echocardiogram revealed left ventricular apical akinesis...

BACKGROUND: Takotsubo cardiomyopathy (TC) is acute, but completely reversible in the absence of significant coronary artery disease. This study aims to assess the functional recovery of regional myocardial deformation in patients with TC using 2-dimensional (2D) speckle tracking echocardiography. METHODS: Thirty-three patients diagnosed with TC (mean age 63 years, 26 female) prospectively underwent serial 2D echocardiography on day 1 (initial presentation), day 4 [the middle, interquartile range (IQR), 2-5 days], and day 21 (recovery, IQR 13-32 days)...

BACKGROUND: Takotsubo cardiomyopathy is a syndrome of transient cardiac dysfunction that is frequently associated with sudden emotional or physical stress. Epinephrine use has been implicated in precipitating Takotsubo cardiomyopathy in multiple case reports and case series. We sought to systematically review the current English literature on this association. METHODS: We searched relevant articles on Takotsubo cardiomyopathy associated with epinephrine administration and extracted data on demographic characteristics, clinical features, investigations and clinical outcomes...

Stress-induced cardiomyopathy (SIC), also known as takotsubo cardiomyopathy (TTC), is a relatively newly-described condition, which has been increasingly reported in the literature. It is characterized by acute onset of symptoms and electrocardiogram changes mimicking myocardial infarction, with transient but completely reversible left ventricular (LV) dysfunction. SIC commonly occurs following physical or emotional stress. The present study discusses the case of a 68-year-old female patient who had suffered from infection of the upper respiratory tract for 10 days before admission to the hospital with symptoms of chest stuffiness and dyspnea that persisted for 2 days...

Most patients diagnosed with takotsubo cardiomyopathies are expected to almost completely recover, and their prognosis is excellent. However, complications can occur in the acute phase. We present a case of a woman with takotsubo cardiomyopathy with right ventricular involvement who developed a rupture of the right ventricular free wall following ventricular septal rupture, as a consequence of an acute increase in right ventricular afterload by left-to-right shunt. Our case report illustrates that takotsubo cardiomyopathy can be life threatening in the acute phase...

A 69-year-old woman undergoing treatment for hypertension and epilepsy was scheduled to undergo cataract surgery. All preoperative examination results were within normal limits. Despite being tense, she walked to the operating room. Approximately 2 minutes after an intravenous line was established by an anesthesia resident, severe hypoxia and bradycardia developed, and she lost consciousness. Cardiopulmonary resuscitation was initiated immediately, and after 1 minute, she regained consciousness, and her breathing and circulation recovered...

Takotsubo cardiomyopathy is an acute reversible form of cardiac failure, firstly described in 1991, with a prognosis not favorable as previously thought. Although high levels of catecholamines have been suggested as the leading mechanism for the onset, the pathophysiology remains unclear. However, several pathophysiological explanations have been proposed, all not mutually exclusive. A complex chain of events is present, including the activation of the hypothalamic-pituitary-adrenal axis, the surge in circulating catecholamines and subsequent cardiovascular responses...

Myocardial bridging (MB) and a long recurrent wraparound left anterior descending artery (wrap-LAD) are coronary anatomic variants that have been recently suggested to be associated with takotsubo syndrome (TS). Until now, coronary artery tortuosity (CAT) has never been investigated in this setting. Our study sought to evaluate the prevalence of the aforementioned anatomic variants in a large population with TS. In this retrospective angiographic study, 109 patients with TS were compared with 109 age- and gender-matched subjects without coronary artery disease, valve heart disease, or cardiomyopathy...

OBJECTIVE: The majority of cardiovascular diagnoses in the Danish National Patient Registry (DNPR) remain to be validated despite extensive use in epidemiological research. We therefore examined the positive predictive value (PPV) of cardiovascular diagnoses in the DNPR. DESIGN: Population-based validation study. SETTING: 1 university hospital and 2 regional hospitals in the Central Denmark Region, 2010-2012. PARTICIPANTS: For each cardiovascular diagnosis, up to 100 patients from participating hospitals were randomly sampled during the study period using the DNPR...

INTRODUCTION: Little is known about the time-course changes in left ventricular myocardial deformation in patients with Takotsubo cardiomyopathy (TC) using layer-specific quantification of myocardial deformation assessed by 2-dimensional speckle tracking echocardiography (2DSTE). CASE SUMMARY: In this retrospective 2DSTE follow-up study of 3 female patients with sepsis-induced TC, we examined changes in strain among the 3 myocardial layers, and examined the changes in left ventricular diastolic function and right ventricular systolic function...
