Takotsubo cardiomyopathy associated with autoimmune polyendocrine syndrome II.

Takotsubo cardiomyopathy (TCM) is a poorly understood condition in which patients with chest pain have a transient ampulla-shaped abnormality of the left ventriculogram, and intact coronary arteries. We report TCM in combination with autoimmune polyendocrine syndrome type II (APS II), which raises new questions about the pathogenesis of TCM.

Acetylcholine-induced coronary spasm with a history of Kawasaki disease: case report.

A 21-year-old woman without any known coronary risk factors was found at coronary catheterization to have normal coronary angiograms, but demonstrated acethylcholine (ACh)-induced coronary spasm. She had a history of Kawasaki disease (KD) at 19 months of age and, although coronary angiography was not performed at that time, no coronary aneurysms were detected by echocardiography. To the best of our knowledge, this is the first case report of ACh-induced coronary spasm associated with normal coronary angiograms in a young person with a history of KD.
