Brief Summary

The Cedars-Sinai SHI Takotsubo Registry and Proteomic Study is an observational registry that will collect retrospective and prospective demographic, clinical, hemodynamic, laboratory and other diagnostic parameters, therapy and outcome data from individuals who meet the inclusion/exclusion criteria of Takotsubo Registry protocol. Subjects will also be invited to provide a blood sample utilizing a Mitra kit sent to their homes. Researchers from the Barbra Streisand Women's Heart Center will analyze Registry data to identify Takotsubo phenotypes, improve diagnostic capabilities, better predict recurrence rates, and develop targeted Takotsubo treatments.
