<qa>  What is the prognosis of patients with TTC believed to be favorable?The prognosis of patients with TTC is believed to be favorable. This assumption is mainly based on the observations of a rapid recovery of global left ventricular function and low cardiac in-hospital mortality. In fact, the clinical course following TTC events after hospital discharge is largely unknown due to a lack of large prospective long-term follow-up studies and inconsistent and limited findings from available studies to date.
