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

Stress cardiomyopathy: Medical studies and extensive review

Stress cardiomyopathy (SC) was first reported in the year 1983. It is narrated as critical but quite commutative left ventricular (LV) malfunction mostly caused by poignant or psychological disorder. Numerous variations of SC have been described as well as reverse stress cardiomyopathy (rSC) which is an adaptation identified by the decreased muscle movement related with hyperkinesis that reconciles impetuously. The signature of rSC is a medical demonstration alike to syndrome by an acute coronary, with no obvious difficult coronary artery disease. The occurrence of SC is approximated to be 4% of all victims conferring with gleaned syndrome by acute coronary. The portion of victims conferring with the rSC transfiguration out of all SC patients has been inconstant, varying from 1 to 24%. Reverse stress cardiomyopathy cases are found to be common with young people, less decrease in left ventricular ejection fraction (LVEF) and more neurological disease compared to the SC. While the correct phenomenon of rSC is undetermined, postulated methods comprises of coronary microvasculature impairment, coronary artery spasm, and estrogen deficiency. Patients with rSC typically suffer with chest pain after an emotional or Psychological stressful event. The rSC can also be happened by general anesthesia, or neurological conditions. The diagnosis of rSC demands the presence of new electrocardiogram (EKG) abnormalities or elevated cardiac troponin, and absence of obstructive coronary disease, pheochromocytoma, or myocarditis. The consideration of rSC is quite analogous to that of SC, which is predominantly supportive with the treatment of complications. The recrudescence rate of rSC is around 12%. The most frequent complications of rSC include pericardial effusions, and development of LV thrombi.

Role of Depression and Anxiety Disorders in Takotsubo Syndrome: The Psychiatric Side of Broken Heart

Takotsubo syndrome (TTS), also called broken heart syndrome, is an acute and transient cardiac wall motion abnormality of the left ventricle. The patient prototype is a post-menopausal woman with myocardial infarction-like symptoms (angina pectoris, breathlessness, palpitations, etc.) who has experienced sudden emotional or physical stress. Although prognosis is generally considered relatively benign, both complications and recurrence rates are not insignificant. Pathophysiological mechanisms underlying TTS are not entirely understood, but the sympathetic system over-activity has a leading role. Moreover, since emotional stress frequently triggers TTS and since precedent diagnosis of psychiatric disorders sometimes coexists, the psychological response to stress could be another potential therapeutic target. Indeed, this article aims to explore the association between underlying depression and anxiety disorders and TTS, as well as to find ideal therapeutic options useful to treat and prevent TTS. Thus in our review, we considered case reports, case-control studies, and review articles from PubMed. Papers dealing with Takotsubo syndrome and anxiety disorder or depression were selected. We included papers published since 2010 and whose abstract was in English. We concluded that anxiety disorders, but not depression, are associated with a higher occurrence of TTS. There is a link between anxiety, TTS, and inflammation leading to increased sympathetic activity. Nevertheless, patients with pre-admission psychiatric disorders have a higher risk of recurrent TTS. Importantly, the use of selective serotonin reuptake inhibitors (SSRIs) could be a potential therapeutic aid in preventing TTS's recurrence in selected patients.

Reverse Takotsubo cardiomyopathy: a comprehensive review

Takotsubo cardiomyopathy (TTC) was first described in Japan in the 1980s. It is described as an acute but often reversible left ventricular (LV) dysfunction mainly triggered by emotional or physical stress. Multiple variants of TTC have been reported including reverse Takotsubo cardiomyopathy (rTTC) which is a variant characterized by the basal akinesis/hypokinesis associated with apical hyperkinesis that resolves spontaneously. The hallmark of rTTC is a clinical presentation similar to an acute coronary syndrome (ACS), with no evident obstructive coronary artery disease. The incidence of TTC is estimated to be 2% of all troponin-positive patients presenting with suspected ACS. The proportion of patients presenting with the rTTC variant out of all TTC patients in published literature has been variable, ranging from 1-23%. Reverse Takotsubo has been associated with younger age, less decrease in left ventricular ejection fraction (LVEF), and more neurological disease compared to the TTC. While the exact mechanism of rTTC is unknown, hypothesized mechanisms include catecholamine cardiotoxicity, coronary artery spasm, coronary microvasculature impairment, and estrogen deficiency. Patients with rTTC typically present with chest pain and/or dyspnea after an emotional or physically stressful event. rTTC can also be triggered by intracranial hemorrhage, general anesthesia, or neurological conditions. Diagnosis of rTTC requires the presence of LV basal hypokinesis/akinesis, new electrocardiogram (EKG) abnormalities or elevated cardiac troponin, and absence of obstructive coronary disease, pheochromocytoma, or myocarditis. Management of rTTC is similar to that of TTC, which is predominantly supportive with the treatment of complications. The recurrence rate of rTTC is around 10%. The most common complications of rTTC include myocarditis, pleural and pericardial effusions, and development of LV thrombi. The best predictors of mortality include decreased LVEF, development of atrial fibrillation, and neurologic disease.

Reverse Takotsubo Cardiomyopathy Following Exploratory Laparotomy

Reverse takotsubo cardiomyopathy is an uncommon cardiomyopathy characterized by reversible regional wall motion abnormalities in the basilar segment of the left ventricle. This happens in the absence of any coronary artery pathology. Although it shares some pathogenic mechanisms with its more common variant, takotsubo cardiomyopathy, differences exist in terms of echocardiographic features, demographics, clinical manifestations, laboratory features, and prognosis. Cases of postoperative reverse takotsubo cardiomyopathy are less described in the literature. Herein, we report a case of reverse takotsubo cardiomyopathy in a 44-year-old woman occurring after exploratory laparotomy.
