The early dynamic of ECG in Takotsubo syndrome presenting with ST-elevation: A comparison with age and gender-matched ST-elevation myocardial infarction

Abstract

 The presenting ECG in Takotsubo is subtly different than the presenting ECG of myocardial infarction, by fewer total abnormal leads, lesser total magnitude of STelevation and lesser pathological Q waves. The 4-day evolution of the Takotsubo ECG compared to acute myocardial infarction is characterised by much more widespread and deeper T wave inversion. The mean QTc progressively increases in takotsubo whilst in MI decreases.

Stress cardiomyopathy following thyroidectomy in a premenopausal woman with thyroid cancer: case report and review of the literature

“…The presentation of SC mimics that of AMI, and 50-60% patients present with chest pain of recent onset (7). ECG changes include ST-segment elevation or depression, abnormal Q-waves, and nonspecific T-wave changes, but ECG can be normal at presentation (8). The levels of serum cardiac biomarkers are mildly raised and that of BNP may be markedly elevated (1).…”

The dynamic of ECG in Takotsubo Syndrome and myocardial infarction: the long quest for an intriguing non-invasive differential diagnosis between ischemic syndromes

“…The presenting ECG (day 0) in TTS showed significantly fewer total abnormal leads, likely due to the lack of reciprocal changes as previously highlighted by Kosuge et al [8], comparable number of ST elevation leads but lesser total magnitude of ST elevation, smaller sum of positive T wave amplitude and lesser number of pathological Q waves. These differences could be partly due to less/no myocardial necrosis without replacement fibrosis, confirmed by the absence of late gadolinium enhancement at cardiac magnetic resonance imaging [7].…”

“…In the present issue of the journal, Scally and colleagues analyzed the data of 27 acute TTS and 37 age and gender matched ST Elevation Myocardial Infarction (STEMI), aiming to a head to head comparison of ECG presentation and progression [7].…”

“…Além disso, causas neuroendócrinas, hormonais, neuropsicológicas e vasculares também têm sido propostas para explicar a condição (LEMOS, A. E. T. et al, 2008;SCALLY, C. et al, 2020). Sua característica especial consiste em ser diagnóstico diferencial do IAM, o que realça a necessidade de ser conhecida pela sociedade médica.…”

“…Sua característica especial consiste em ser diagnóstico diferencial do IAM, o que realça a necessidade de ser conhecida pela sociedade médica. (SCALLY, C. et al, 2020). Diante da semelhança dessas patologias, esse estudo tem como objetivo relatar os achados da literatura que permitem diferenciar CT de IAM, a fim de esclarecer sua abordagem diagnóstica, evitando que seja subdiagnosticada.…”
