The etiology of this syndrome is not clear, but it is likely that direct catecholamine toxicity to the susceptible myocardium plays a role. The syndrome is most common in women and has been described in association with a variety of forms of physiologic or emotional stress. In general, the prognosis is favorable and complete recovery is common.
