Abstract

Takotsubo cardiomyopathy (TTC) is characterized by reversible left ventricular (LV) systolic dysfunction independent of fixed coronary disease or coronary spastic pathogenesis. A number of investigators have documented marked elevation of natriuretic peptide levels at presentation in such patients. We sought to determine the pattern, extent, and determinants of the release of N-terminal pro-B type natriuretic peptide/B type natriuretic peptide (NT-proBNP/BNP) in patients with TTC. We evaluated NT-proBNP/BNP release acutely and during the first 3 months in 56 patients with TTC (96% women, mean age 69 ± 11 years). The peak plasma NT-proBNP levels were compared to the pulmonary capillary wedge ..
