Takotsubo Syndrome: A Review of Presentation, Diagnosis and Management.

Takotsubo Syndrome (TTS) is a condition of transient left ventricular dysfunction that is typically triggered by emotional or physical stress. Since first described in Japan in 1990, it has increasingly been recognised in clinical practice, accounting for up to 2% of Acute Coronary Syndrome (ACS) presentations. In fact, the clinical presentation can be indistinguishable from a myocardial infarction.

Comparing the clinical and prognostic impact of proximal versus nonproximal lesions in dominant right coronary artery ST-elevation myocardial infarction.

Objective: To evaluate the prognostic significance of culprit lesion location in dominant right coronary artery (RCA) ST-elevation myocardial infarction (STEMI).

Background: In RCA STEMI, proximal culprit lesions have been shown to have higher rates of acute complications such as bradycardia and cardiogenic shock (CS) but data on mortality is limited.

Methods: We retrospectively identified and analyzed data from consecutive patients with a dominant RCA STEMI who underwent either primary or rescue percutaneous coronary intervention (PCI) between January 2003 and December 2016.
