Cardiac Arrest in Takotsubo Cardiomyopathy

[...]an episode of TTC seems to induce immunity, by an unknown mechanism, consistent with clinical experience (5% to 10% probability of recurrence). Recent attempts to produce TTC experimentally in animal models were based on the catecholamine theory, but they failed to show some typical features of human TTC: mortality was quite high (15% to 40% instead of ~2%), dyskinesia was atypical of TTC, and acquired residual immunity (so that recurrence and re-inducibility of TTC are rare after an event) was not demonstrated.3 During the past few years, we have used ACH to study patients presenting with a cardiac arrest preceded by chest pain.
