Manganese-enhanced Magnetic Resonance Imaging in Takotsubo Cardiomyopathy

The goal of this research study is to further understand the physiological mechanisms involved in a heart condition called takotsubo cardiomyopathy, also known as broken heart syndrome. Furthermore, the investigators will be assessing the effects different cardiac medications have on these physiological mechanisms. This will be achieved by performing cardiac MRI scans using a special dye called manganese. Manganese uptake in the heart is altered in patients with takotsubo cardiomyopathy. The investigators will study the effects that different cardiac medications have on manganese uptake.

Inclusion Criteria: * Males and females \>18 years of age * Clinical presentation of takotsubo cardiomyopathy * Have capacity to give formal consent Exclusion Criteria: * Unable to tolerate or contraindication to magnetic resonance imaging * Renal failure (estimated glomerular filtration rate \
