Levels of troponin release can aid in the early exclusion of stress-induced (takotsubo) cardiomyopathy.

Abstract

Among patients with takotsubo cardiomyopathy, troponin T level correlated with initial ejection fraction. Furthermore, the diagnosis of takotsubo cardiomyopathy appears to be unlikely in patients with troponin T greater than 6 ng/mL or troponin I greater than 15 ng/mL.
