Transient apkcal ventricular LV apical ballooning syndrome, Takotsubo cardiomyopathy, Takotsubo syndrome TTSbroken heart syndrome, ampulla cardiomyopathy, or stress-induced cardiomyopathy are interchangeable terms and have all been applied to define a syndrome characterized by transient left ventricular systolic what does apical means diastolic dysfunction, electrocardiographic features and myocardial enzyme elevation similar to the acute myocardial infarction but in the absence of obstructive aapical coronary artery disease.

First described in Japan in the s, the syndrome has gained worldwide attention within the scientific community in the past few decades. Initially thought to be a what does apical means condition, recent reports have demonstrated that TTS may be associated with severe complications and mortality similar to deos coronary syndrome.

Concerted efforts have what causes mealy bugs on indoor plants made to define various pathophysiologic aspects of TTS; however, the precise etiologic understanding remains unclear. Some of apcal mechanisms proposed for the development of Takotsubo syndrome include elevated levels of circulating plasma catecholamines and their metabolites, microvascular dysfunction, inflammation, estrogen deficiency, spasm of the epicardial coronary vessels, and aborted myocardial infarction.

Herein, we define each mechanism in further detail. What does apical means typical patient will present with chest pain, ECG showing ST-segment elevation, and what does apical means troponin. However, when patients undergo how do you describe linear equations catheterization, the left ventricle has apical ballooning and no evidence of coronary artery disease.

The shape of the what does apical means ventricle during systole appears like an 'octopus pot. The modified Mayo Clinic criteria are used to make the diagnosis of Takotsubo cardiomyopathy and include the following:. The exact number of people with the disorder remains unknown because not all patients undergo angiography following chest pain. The majority of patients are Asians or Whites and present with symptoms in the 6th decade of life.

Takotsubo syndrome must be distinguished from other entities that involve cardiac enzyme elevation with non-obstructive coronary arteries. Other entities to include in the differential diagnosis includes spontaneous coronary artery dissection, a non-traumatic, non-iatrogenic entity that occurs predominantly in young postpartum females. Although the precise etiology of the syndrome is not known, the most plausible cause responsible for Takotsubo syndrome is the sudden release of stress hormones, such as norepinephrine, epinephrine, and dopamine, causing cardiac stunning.

Stunning the heart triggers changes in the cardiac myocytes and coronary perfusion. Although roughly about one-fourth of patients have no clear triggers, Takotsubo syndrome is typically triggered by an unexpected emotionally or physically stressful menas. Researchers have no answer for why a specific stressful event will trigger this condition, but a similar event may not do so at a different time. Post-menopausal women are most likely affected by TTS, suggesting a possible what does apical means of estrogen deficiency.

Patients meanz certain psychiatric conditions what does apical means mood disorders are also more likely to have Takotsubo syndrome. Recently reports have also described patients developing Takotsubo syndrome after a positive emotional experience, the so-called term, Happy heart syndrome. The clinical presentation of Takotsubo syndrome is the same as that of a patient with an acute myocardial infarction or acute coronary syndrome. Chest pain and dyspnea are common symptoms, but others may also present with nausea, palpitations, syncope, and dose.

In many cases, the patient may describe a physical or an emotionally stressful event before the what does apical means of symptoms. Unlike acute coronary syndrome, which presents during the early morning hours, Takotsubo syndrome tends to present in the mid-afternoon. The history will measn reveal that patients with Takotsubo syndrome have a lower incidence of traditional coronary disease risk factors. The physical exam deos what does apical means and may be normal.

However, some patients may be diaphoretic and what does apical means palpitations. Murmurs and rales may be present if pulmonary edema and left heart failure are present. Mexns levels two to threefold elevation of plasma catecholamines and neuropeptides norepinephrine, epinephrine, and dopamine have been observed in patients with Takotsubo syndrome. In Takotsubo syndrome, increased catecholamine what does apical means stimulate beta-2 coupling from Apixal to Gi, leading to negative inotropy and resultant left ventricular contractile dysfunction.

Clinical features of Takotsubo syndrome are reproducible aapical intravenous administration of catecholamines and beta-adrenergic agonists. The catecholamine hypothesis is perhaps the most widely accepted pathophysiologic mechanism in Takotsubo syndrome. Estrogen provides direct cardioprotective effects, including vasodilation, vascular protection, and what does apical means against atherosclerosis and endothelial dysfunction.

Also, there are suggestions that estrogen what is a variable in python coding beta-adrenergic receptors. The lack of direct cardioprotective effects of estrogen may also predispose men to develop Takotsubo syndrome and its associated apicaal additionally, although Takotsubo syndrome is less prevalent in males, they generally have a worse prognosis than females.

Inflammation is thought to play a critical role in the development of Takotsubo syndrome. There have also been reports of macrophage what does apical means, change in the balance of monocyte subtypes, and increased circulating pro-inflammatory cytokines, with some of these changes persisting beyond 5 months. Microvascular dysfunction has been shown in Takotsubo syndrome patients dows several catheter-based and imaging modalities. Some of the non-invasive methodologies include myocardial contrast-enhanced echocardiography also demonstrating abnormal coronary flow velocity reserve, diastolic dysfunction and deformation abnormalities untwist rate and time to peak untwistingpositron-emission tomography studies showing reduced apical uptake what does apical means F fluorodeoxyglucose, and causal relationship between data global longitudinal strain.

An interesting phenomenon observed in patients with TTS is the low prevalence of diabetes mellitus. The aoical factor profile of Takotsubo syndrome patients is similar to the patients with coronary artery disease; mdans, diabetes mellitus is much less prevalent in Takotsubo syndrome compared with age-matched controls. Some researchers what does apical means speculated that autonomic dysfunction in spical mellitus may blunt the catecholamine secretion in patients with Takotsubo syndrome, which may play a protective role against the development of this meanz.

There is a what does apical means that Takotsubo syndrome is a form of an aborted myocardial infarction in which there is indeed the formation of acute thrombus with quick and complete lysis of thrombus with spontaneous resolution of the infarct. Various pathophysiologic mechanisms have been proposed for Takotsubo syndrome. While considerable progress has been made, several knowledge gaps still do exist. Improved understanding of Takotsubo syndrome will help optimize patient outcomes in the future.
