TTS is associated with different repolarization disorders including ST-segment elevation. ST elevation myocardial infarction (STEMI) in ACS is associated with declined prognosis. However, the clinical and prognostic impact of ST-segment elevation on TTS remains lacking. Aim: The aim of this study was to determine the short- and long-term prognostic impact of ST-segment elevation on TTS patients as compared with STEMI patients. Patients and methods: Our institutional database constituted a consecutive cohort of 138 TTS patients and 138 ACS patients matched for age and sex. TTS patients (n=41) with ST-segment elevation were compared with ACS patients with ST-segment elevation (n=64). Results: Chest pain was significantly more documented in STEMI patients as compared with TTS patients (48.8% vs 78.1%; P |
