Study summary

GEIST is a multicenter, international observational registry of patients with Takotsubo syndrome. Data regarding the clinical profile (demographic characteristics, clinical presentation, laboratory measures, electrocardiography /echocardiography / coronary angiography parameters, treatment and medication), in-hospital course and complications and short-/long-term outcome are collected prospectively and retrospectively to increase the understanding of the disease.

Read the detailed description

The open-ended, multicenter, international GEIST registry collects data from patients with Takotsubo syndrome during the index hospitalization and follow-up. Furthermore, long-term outcome data are acquired with structured telephone interviews, in case patients do not undergo regular outpatient visits in the participating study centers. The GEIST registry retrospectively includes data, which have already been collected, and prospectively continues to enroll patients with newly diagnosed Takotsubo syndrome.
