Coronary Artery Disease in Takotsubo Cardiomyopathy

Abstract
Background Significant coronary artery disease (CAD) is generally considered as an exclusion criterion for the diagnosis of takotsubo cardiomyopathy (TC). However, this may not be justified in all cases, because TC and CAD may coincide. Methods and Results Among 821 consecutive patients who underwent urgent left heart catheterization for suspected acute coronary syndrome between December 2004 and August 2006 those with a final diagnosis of TC who also had a stenotic lesion (diameter stenosis on quantitative coronary angiography >50% and Circ J 2007; 71: 1092 - 1094)
