Tei Index Complements Conventional Echocardiographic Parameters in Diagnostic Workup of Suspected Takotsubo Syndrome

Background: Tei index (TI) is a combined myocardial performance index for overall cardiac function, the sensitivity of which seems to be better than that of systolic and diastolic parameters alone. Evidence for TI in the context of Takotsubo syndrome (TTS) is currently limited, which is why we chose to investigate this parameter in affected patients. Subjects and Methods: Patients with TTS (n = 51), acute coronary syndrome (ACS; n = 29) and controls (n = 58) were retrospectively investigated. Laboratory and echocardiographic parameters including TI were analyzed for their ability to discriminate TTS in the total study cohort. Results: TI was highest, and thus most pathological, in patients with TTS (median 0.516 vs. ACS: 0.355 vs. control: 0.313, p
