Management of Tako-tsubo syndrome

The Association Between the Location of Subarachnoid Hemorrhage and the Occurrence of Takotsubo Cardiomyopathy: A Systematic Review and Meta-analysis

Takotsubo cardiomyopathy (TCM) is a syndrome characterized by transient regional cardiac dysfunction of the left ventricle. The goal of this review is to better understand the relationship between the anatomic locations of subarachnoid hemorrhages (SAHs) and the development of TCM as identified through a review of cohort studies. From inception to December 2023, we systematically explored major electronic medical information sources to identify cases of TCM that developed after SAHs. The six selected studies included in the meta-analysis suggest a modest but statistically significant increase in the odds of the events in the posterior circulation group compared to the anterior circulation group, with a combined odds ratio (OR) estimate of around 1.45-1.46. The fixed effect model gives an overall OR of 1.45 with a 95% confidence interval (CI) of 1.01 to 2.10, z = 2.01, p = 0.0442, while the random effects model yields a slightly higher OR of 1.46 with the same 95% CI, z = 2.03, p = 0.0425. There is a tendency for SAH occurrence in the posterior cerebral circulation to cause SAH-related TCM more frequently than in the anterior cerebral circulation.

Takotsubo cardiomyopathy following pericardiectomy: A case report

BACKGROUND

Takotsubo cardiomyopathy (TC) is defined as a temporary and reversible systolic abnormality of the left ventricle's apical area resembling myocardial infarction in the nonexistence of coronary artery disease. Only a few cases have been reported after cardiac operations or after pericardiocentesis.

AIM

To emphasize the need to be aware of the possibility of the occurrence of this potentially fatal complication after cardiac surgery.

MATERIALS AND METHODS

A 66-year-old man underwent a pericardiectomy. He progressed to exacerbation of hemodynamic instability postoperatively and was diagnosed with TC, finally, he had to be supported by an intra-aortic balloon pump (IABP), extracorporeal membrane oxygenation (ECMO).

RESULTS

Patient's left ventricle function recovered fully in 2 weeks.

DISCUSSION

We discussed the pathogenesis and treatment of postoperative TC.

CONCLUSION

TC has to be carefully considered in the differential diagnosis in case of acute left ventricle dysfunction following cardiac surgery.

[Clinical Manifestation of Stressful Cardiomyopathy (Takotsubo Syndrome) and the Problem of Differential Diagnosis with Acute Myocardial Infarction]

The presented data show that tacotsubo syndrome (TS) is characterized by the absence of coronary artery obstruction, cardiac contractile dysfunction, apical ballooning, and heart failure, and in some patients, ST-segment elevation and prolongation of the QTc interval. Every tenth patient with TS develops ventricular arrhythmias. Most of TS patients have elevated markers of necrosis (troponin I, troponin Т, and creatine kinase МВ (CK-МВ), which are considerably lower than in patients with acute myocardial infarction (AMI) with ST-segment elevation. The level of N-terminal pro-B-type natriuretic peptide (NT-proBNP), in contrast, is considerably higher in patients with TS than with AMI. Differential diagnosis of TS and AMI should be based on a multifaceted approach using coronary angiography, echocardiography, analysis of ECG, magnetic resonance imaging, single-photon emission computed tomography, and measurement of troponins, CK-MB, and NT-proBNP.

Perioperative takotsubo cardiomyopathy: Implications for anesthesiologist

Takotsubo cardiomyopathy (TCM) is characterized by transient ventricular dysfunction in the absence of obstructive coronary artery disease that may be triggered by an acute medical illness or intense physical or emotional stress. TCM is often confused with acute myocardial infarction given the similar electrocardiographic changes, cardiac enzymes, hemodynamic perturbations, and myocardial wall motion abnormalities. In the perioperative setting, the clinical picture may be more confusing because of the effect of anesthesia as well as hemodynamic changes related to the surgery itself. However, awareness of various other diagnostic modalities may enable clinicians to distinguish between the two, more systematically and with greater certainty. Despite the large body of literature, there still seems to be an overall paucity in our understanding of the etiopathogenesis, clinical characteristics, natural history, and management of this syndrome, especially in the perioperative setting. This narrative review seeks to present and synthesize the most recent literature on TCM and to identify gaps in current knowledge which can become the basis for future research.

Acute left ventricle failure on induction of anesthesia: a case report of reverse stress cardiomyopathy-presentation, diagnosis and treatment

Reverse takotsubo cardiomyopathy (TCM) is a less common variant of classic TCM that presents within a different patient profile and with its own hemodynamic considerations. A 46-year-old woman was admitted to our hospital for laryngoscopy and possible balloon dilatation for tracheal stenosis under general anesthesia. One year prior to this admission, the patient was admitted after a motor vehicle accident with subdural hematoma, subarachnoid hemorrhage, and fracture of the eighth thoracic vertebra. She underwent uneventful anesthesia for thoracic spine surgery and tracheostomy to help her wean from the ventilator during that admission. Since her previous admission, she developed posttraumatic anxiety and depression (a neuropsychiatric disorder triggered by subdural hematoma and subarachnoid hemorrhage) and was treated with antianxiety and antidepressant medication. At this admission, the patient developed acute left ventricle failure on induction of anesthesia secondary to reverse TCM. We report a case of reverse TCM, where posttraumatic emotional stress of a neuropsychiatric disorder combined with physical stress from anesthesia and laryngoscopy triggered TCM in a patient with previous uneventful anesthesia 1 year earlier.

Takotsubo syndrome (stress cardiomyopathy): an intriguing clinical condition in search of its identity

Takotsubo syndrome is a relatively frequent clinical entity presenting typically as an acute coronary syndrome in the absence of obstructive coronary artery disease and characterized angiographically by transient left ventricular systolic dysfunction, sparing the basal segments of the left ventricle ("apical ballooning"). Takotsubo syndrome characteristically affects peri- or postmenopausal women, albeit recent series show that men also are at risk. Takotsubo syndrome is characteristically triggered by severe emotional or physical stress, which suggests a pathogenic role for increased sympathetic activity leading to myocardial perfusion abnormalities and ventricular dysfunction. The reasons why severe emotional and physical stress result in the development of takotsubo syndrome in certain individuals but not others is still a matter of speculation, but strongly suggests the existence of predisposing factors/mechanisms in certain subjects. The present article reviews the different factors that can play a role in the development of takotsubo syndrome in different patients. We propose that triggers (ie, emotional stressors, physical stressors, iatrogenic stressors, and neurologic triggers), pathogenic mechanisms (ie, increased catecholamine levels, coronary vasomotor abnormalities leading to myocardial ischemia), and predisposing factors (ie, cardiovascular risk factors, endothelial dysfunction, comorbidities) all interact in a complex fashion and possibly differently in different patients to cause takotsubo syndrome. Identifying these factors may help in preventing and managing the condition more effectively.

Takotsubo cardiomyopathy--a clinical review

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.

Reversible cardiomyopathies--a review

End-stage renal disease, cirrhosis, obesity, tachycardia, and extreme stress have all been shown to result in impaired left ventricular function. It is becoming clear, however, that the cardiomyopathies associated with these states are reversible after resolution of the underlying process. In this article, we present the current data demonstrating that renal transplantation, liver transplantation, and bariatric surgery can lead to reversal of uremic, cirrhotic, and obesity cardiomyopathies, respectively. We also discuss the reversibility of tachycardia-induced cardiomyopathy after radiofrequency ablation or pharmacologic therapy for rate or rhythm control and the reversibility of stress-induced cardiomyopathy with supportive care.

Perioperative transient left ventricular apical ballooning syndrome: Takotsubo cardiomyopathy: a review

Transient left ventricular apical ballooning syndrome (TLVAB), also known as Takotsubo cardiomyopathy, is a cardiac syndrome characterized by transient left ventricular dysfunction in the absence of obstructive atherosclerotic coronary artery disease. An episode of emotional and/or physiologic stress frequently precedes presentation of this syndrome. TLVAB may initially present as an acute coronary syndrome characterized by chest pain, pulmonary edema, electrocardiographic changes, elevated cardiac enzymes, and cardiogenic shock. This syndrome is still underestimated today and the potential appearance of TLVAB during the perioperative period can be a great challenge. Adequate beta-blockade is the mainstay in the treatment of patients with TLVAB during the acute phase and also for long-term management.

[Tako-Tsubo cardiomyopathy]

Tako-Tsubo cardiomyopathy (TK) is an acutely appearing myocardial disease leading to impaired cardiac function, which can barely be distinguished clinically from an acute myocardial infarction. It occurs mainly in postmenopausal women and usually has a good prognosis. The pathophysiology of TK still remains to be elucidated but the favoured hypothesis is myocardial damage induced by catecholamine excess. Various acute diseases, emotional stress, surgical procedures and anaesthesia have been described as possible causes for TK. Little is known about the optimal therapy, however, there might be potential differences in the therapy of TK compared to contemporary therapy algorithms for heart failure. Knowledge of TK as a differential diagnosis for acute myocardial infarction is necessary to avoid incorrect treatment.

Medical mystery: an unusual cause of anaemia

An 82-year-old Indian man presented with a month's history of increasing lethargy, shortness of breath and 2 kg weight loss. No significant past illness was elicited, specifically no history of change in bowel habit, malaena, haematemesis, fever, abdominal or chest pain. At admission, he was on oral iron therapy only and was a non-smoker who rarely drank alcohol. On examination he was pale, haemodynamically stable, with normal cardiorespiratory, abdominal and digital rectal examinations.

Mechanisms of stress (Takotsubo) cardiomyopathy

Stress cardiomyopathy, also referred to as Takotsubo cardiomyopathy, transient apical ballooning or broken heart syndrome, is a disorder associated with transient left ventricular dysfunction. Symptoms include acute chest pain and dyspnea accompanied by electrocardiographic changes, such as ST-segment elevation and T-wave inversions, minimal elevation of cardiac enzyme levels and transient wall-motion abnormalities in the absence of substantial coronary artery obstruction. Complete recovery of contractile function has been documented in nearly all cases, but the mechanisms of disease remain unclear and the cause has not been established. Coronary artery vasospasm, microcirculation dysfunction, and transient obstruction of the left ventricular outflow tract have been proposed as possible causes of this disorder. An excessive release of catecholamines also seems to have a pivotal role in the development of stress cardiomyopathy. This Review summarizes published data on stress cardiomyopathy, focusing primarily on the most likely causes of this cardiac entity.

[Tako-Tsubo syndrome after anaphylaxis caused by succinylcholine during general anaesthesia]

The Tako-Tsubo syndrome (or transient left ventricular apical balloning) is a new clinical entity, very similar to acute myocardial infarction, but different by its excellent short-term prognosis. It has been reported after a physical or an emotional stress, and it is diagnosed by a coronary angiogram and a left ventriculography. We report here a case of Tako-Tsubo syndrome related to an anaphylactic shock caused by succinylcholine during general anaesthesia of a female patient, wearing an unadjustable gastric band.
