ECG Changes and Their Prognostic Impact in Patients With Takotsubo Syndrome

Abstract

Aim: Within this study, we investigated ECG changes in acute patients diagnosed with Tako Tsubo syndrome (TTS) and report on the prognostic impact of the respective ECG patterns. Methods and Results: This single-center study included 101 consecutive patients diagnosed with TTS between 2006 and 2017. Upon 12-lead admission ECG, 59 patients had ST-segment elevation (58%, STEMI), 9 patients had only ST-segment depression (9%, NSTEMI) and 27 T-wave inversion (27%, NSTEMI). Patients who were admitted to the hospital 12 hours after symptom onset were more likely to present with Twave inversion on ECG (T-inversion 47% vs. STelevation 23% ST, p= 0,05). T-wave inversion was also

“…However, in the last years, studies showed that TTS may cause multiple fatal complications, resulting in in‐hospital mortality between 1% and 8%. 4 , 35 , 36 , 37 , 38 In agreement with previously published studies, the all‐cause in‐hospital mortality in our study was 2.3% in period 1 and 2.8% in period 2. Moreover, there was no difference in in‐hospital and 30‐day all‐cause mortality between the two periods.…”

“…Because of the complete recovery of the left ventricle function, TTS was initially considered a benign condition. However, in the last years, studies showed that TTS may cause multiple fatal complications, resulting in in‐hospital mortality between 1% and 8% 4,35–38 . In agreement with previously published studies, the all‐cause in‐hospital mortality in our study was 2.3% in period 1 and 2.8% in period 2.…”
