The pathophysiology of takotsubo syndrome (TTS) is still elusive; many hypotheses of its cause have been proposed with a heightened activity of the peripheral autonomic sympathetic nervous system (PASNS) via local norepinephrine release, and direct cardiomyocyte toxicity mediated by blood-borne catecholamines, being among the most currently entertained. Monitoring of PASNS during hospitalization will provide a metric which could be of immense value in unraveling of the pathophysiology and aiding in the management of the patients with TTS by predicting in-hospital complications, long-term outcome, and its recurrence...

A phaeochromocytoma (PC) is a rare, catecholamine-secreting neuroendocrine tumour arising from the adrenal medulla. Presenting symptoms of this rare tumour are highly variable but life-threatening multiorgan dysfunction can occur secondary to catecholamine-induced hypertension or hypotension and subsequent cardiovascular collapse. High levels of circulating catecholamines can induce an acute stress cardiomyopathy, also known as Takotsubo cardiomyopathy. Recent studies have focused on early diagnosis and estimation of the prevalence of acute stress cardiomyopathy in patients with PC, but very little is reported about management of these complex cases...

BACKGROUND : Takotsubo cardiomyopathy is an increasingly recognized acute heart failure syndrome precipitated by intense emotional stress. Although there is an apparent rapid and spontaneous recovery of left ventricular ejection fraction, the long-term clinical and functional consequences of takotsubo cardiomyopathy are ill-defined. METHODS : In an observational case-control study, we recruited 37 patients with prior (>12-month) takotsubo cardiomyopathy, and 37 age-, sex-, and comorbidity-matched control subjects...

CONTEXT: Pheochromocytoma and paraganglioma are rare neuroendocrine tumors which overproduce catecholamines and arise from the adrenal gland or extra-adrenal chromaffin cells of the sympathetic and parasympathetic ganglia (1). Excessive catecholamine-induced stimulation of cardiac myocytes leads to damage which manifests in several forms ranging from Takotsubo to dilated cardiomyopathy. Diagnosis of pheochromocytoma-related cardiomyopathies is often delayed due to the atypical presentation associated with many cases...

Circulating cardiodepressant factors were found to mediate cardiac dysfunction in patients with sepsis and acute systolic heart failure. To investigate the presence of circulating cardiodepressant factors in patients with Takotsubo Cardiomyopathy (TC), plasma samples were collected from 4 patients with TC, 3 with septic shock, 5 with acute systolic heart failure and 4 healthy controls and injected intraperitoneally in mice. The cardiodepressant effects are measured with transthoracic echocardiography. Plasma injection from control and TC subjects had no effects on left ventricle ejection fraction (LVEF) whereas plasma from the other two groups induced a significant reduction in LVEF...

Recent studies have indicated that patients with takotsubo cardiomyopathy (TTC) have a higher mortality rate than the general population. There is a distinct possibility that TTC could be associated with adverse life-threatening complications like cardiopulmonary failure. Our institutional database constituted a collective of 114 patients diagnosed with TTC. The frequency, determinants and predictors of cardiopulmonary failure were assessed. The patients were subsequently classified into two groups based on the presence (n = 44, 38...

INTRODUCTION: Takotsubo Cardiomyopathy is a transient non-ischemic cardiomyopathy usually characterized by apical ballooning of the left ventricle, with electrocardiographic changes and enzyme release, without evidence of obstructive coronary artery disease. Typically seen in stress induced situations, in post-menopausal females, this condition may have a predilection for patients with dependency disorders. CASE: The following is a case in which Takotsubo Cardiomyopathy was induced by withdrawal from opiate medications...

Takotsubo cardiomyopathy (TCM) is a condition that is characterized as a transient ventricular dysfunction in the absence of obstructive coronary artery disease (CAD) and is usually triggered by an acute medical illness or intense physical or emotional stress. Multiple cases of perioperative TCM (pTCM) have been reported from around the world, but a qualitative analysis of these cases has not yet been done. For this systematic review, we searched PubMed for case reports and case series of pTCM published from 1966 to April 2015 with the objective being to evaluate whether differences in demographics, clinical features and outcomes exist between pTCM and nonperioperative (npTCM), as well as to attempt to identify any predictors of the severe form of pTCM, which requires mechanical circulatory support (MCS) devices or leads to death...

Takotsubo syndrome, also known as stress-induced cardiomyopathy (SC), is underrecognized in cancer patients. This study aims to investigate the incidence, natural history, and triggers of SC in cancer patients and its impact on cancer therapy and overall survival. A total of 30 subjects fulfilled the diagnostic criteria for SC at MD Anderson Cancer Center over a 6-year period. Clinical presentation, electrocardiogram, laboratory data, and transthoracic echocardiogram results registered during the acute phase and follow-up were collected...

Context: Catecholamine-related factors are currently the most popular explanation for the occurrence of Takotsubo syndrome. The aldosterone-related mechanism, however, has not been proposed. Case Description: A 45-year old male, presenting with ST-segment elevation myocardial infarction (STEMI), was finally diagnosed with primary aldosteronism, severe hypokalemia, and Takotsubo syndrome. After excluding the known conditions of apical ballooning and the factors of vasospasm, primary aldosteronism is considered as the major contributor to the development of the Takotsubo syndrome...

Bupivacaine is a long-acting local anesthetic (LA) used for cutaneous infiltration, peripheral nerve blocks, epidural and spinal anesthesia. However, its application may result in cardiovascular complications such as: hypotension, bradycardia, cardiac arrest and toxic myocardial injury. The authors describe a 53-year-old male with a history of cigarette smoking, admitted for an elective inguinal hernia surgery. Before surgery, the patient received subarachnoid injection of bupivacaine (20 mg). After the operation, he developed transient hypotension...

Takotsubo cardiomyopathy (TC) is characterized by reversible ventricular dysfunction, not limited to the distribution of an epicardial coronary artery. A disease primarily afflicting post-menopausal women, it is frequently mistaken for acute anterior wall myocardial infarction. Alternatively called Stress Cardiomyopathy, physical or emotional triggers are identified in only three fourths of TC patients. Long considered a benign condition, recent findings suggest poor short term prognosis similar to acute coronary syndrome (ACS)...

BACKGROUND: Although the current diagnostic criteria require that culprit coronary artery disease be ruled out before the diagnosis of Takotsubo syndrome (TTS) is made, performing coronary artery evaluation (CAE) in patients with serious backgrounds is sometimes challenging. METHODS: We conducted a retrospective cohort study using the Diagnosis Procedure Combination database in Japan. We identified patients in whom TTS was diagnosed at Japanese Circulation Society board-certified teaching hospitals from April 2011 to March 2014 and divided eligible patients into those who underwent CAE (coronary angiography or coronary computed tomography angiography) during hospitalization and those who did not...
