International Expert Consensus Document on Takotsubo Syndrome (Part I): Clinical Characteristics, Diagnostic Criteria, and Pathophysiology

TLDR
The clinical expert consensus document part I summarizes the current state of knowledge on clinical presentation and characteristics of TTS and agrees on controversies surrounding TTS such as nomenclature, different TTS types, role of coronary artery disease, and etiology.
Abstract
Takotsubo syndrome (TTS) is a poorly recognized heart disease that was initially regarded as a benign condition. Recently, it has been shown that TTS may be associated with severe clinical complications including death and that its prevalence is probably underestimated. Since current guidelines on TTS are lacking, it appears timely and important to provide an expert consensus statement on TTS. The clinical expert consensus document part I summarizes the current state of knowledge on clinical presentation and characteristics of TTS and agrees on controversies surrounding TTS such as nomenclature, different TTS types, role of coronary artery disease, and etiology. This consensus also proposes new diagnostic criteria based on current knowledge to improve diagnostic accuracy.

Takotsubo Syndrome: Is this a Common Occurrence in Elderly Females after Hip Fracture?

TL;DR: At least 15% of patients with hip fracture and preoperative myocardial damage had Takotsubo syndrome, a favourable long term prognosis contrary to myocardIAL infarction.

ECG differences and ECG predictors in patients presenting with ST segment elevation due to myocardial infarction versus takotsubo syndrome

TL;DR: In this article , the authors compared electrocardiogram (ECG) in Takotsubo syndrome (TS) versus ST elevation myocardial infarction (STEMI) patients and found that admission ECG in STE-TS was similar to LAD STEMI but reciprocal ST depression was less common compared with STEMI overall.

Optical Coherence Tomography and Coronary Dissection: Precious Tool or Useless Surplus?

TL;DR: The use of OCT in the evaluation of SCAD should be defined by balancing the diagnostic benefits versus procedural risks, as SCAD is a rare condition and OCT is a recently introduced technique in clinical practice, limited data is available in literature.

Takotsubo syndrome during surgery for pheochromocytoma: an unexpected complication.

TL;DR: In this article, a case of rapid onset of systolic dysfunction with cardiogenic shock, which developed after the surgical excision of an adrenal gland tumor in a 60-year-old male, was presented.

Neurohumoral Features of Myocardial Stunning Due to Sudden Emotional Stress

TL;DR: Emotional stress can precipitate severe, reversible left ventricular dysfunction in patients without coronary disease andaggerated sympathetic stimulation is probably central to the cause of this syndrome.

Circadian variation in the frequency of onset of acute myocardial infarction

TL;DR: If coronary arteries become vulnerable to occlusion when the intima covering an atherosclerotic plaque is disrupted, the circadian timing of myocardial infarction may result from a variation in the tendency to thrombosis.

Clinical Features and Outcomes of Takotsubo (Stress) Cardiomyopathy

Christian Templin, +68 more
TL;DR: Patients with takotsubo cardiomyopathy had a higher prevalence of neurologic or psychiatric disorders than did those with an acute coronary syndrome and physical triggers, acute neurologics or psychiatric diseases, high troponin levels, and a low ejection fraction on admission were independent predictors for in-hospital complications.

Apical ballooning syndrome (Tako-Tsubo or stress cardiomyopathy): A mimic of acute myocardial infarction

TL;DR: Apical ballooning syndrome should be included in the differential diagnosis of patients with an apparent acute coronary syndrome with left ventricular regional wall motion abnormality and absence of obstructive coronary artery disease, especially in the setting of a stressful trigger.
