Abstract 19504: Sudden Cardiac Death in Takotsubo Syndrome: Results From a Multicenter, International Registry

Introduction: Cardiac arrest (CA) has been often reported in Takotsubo syndrome (TTS), however scarce data is available on the true prevalence and the natural history of this event. Hypothesis: To investigate the prevalence, clinical features and impact on mortality of CA occurring in the acute phase of TTS. Methods: Patients were enrolled from the InterTAK Registry, an international, multicenter registry of patients with TTS. Patients’ records were analysed for the occurrence of CA. Patiens`underlying heart rhythm (ventricular fibrillation [VF] or tachycardia [VT], pulseless electrical activity [PEA] or asystolia) at index event and timing of CA was determined. Main outcomes were 60-days and 5-years mortality. Results: Out of 2098 patients, CA was reported in 170 patients (8.1%; 121 with medical records available). Patients with CA were younger, more frequently males and with the apical ballooning type, had more often atrial fibrillation, acute neurological comorbidities and physical triggers. On admissi...
