Release patterns of copeptin and troponin in Tako-Tsubo cardiomyopathy

► Elevated serum copeptin levels can be found in approximately 50% of patients with acute Tako-Tsubo cardiomyopathy. ► Copeptin levels prior to cardiac catheterization do not differ significantly between patients with Tako-Tsubo cardiomyopathy and matched control patients with acute myocardial infarction. ► Patients with Tako-Tsubo cardiomyopathy and a typical (apical) ballooning pattern show significantly lower levels of copeptin as compared to patients with an atypical (midventricular) wall motion abnormality.
