DEVIGGIANO, Alejandro et al. Assessment of Coronary Arteries of Patients with Takotsubo Syndrome using Multislice Computed Tomography: Lesions and Pathophysiological Inferences. Rev. argent. cardiol. [online]. 2009, vol.77, n.3, pp. 227-230. ISSN 1850-3748.
The presence of reversible left ventricular dysfunction induced by emotional stress has been extensively reported; however, its mechanism still remains unknown. We describe two patients with the typical clinical picture of Takotsubo syndrome: chest pain following mental stress, transient left ventricular dysfunction and coronary arteriography with normal coronary arteries. Both patients underwent multislice computed tomography scans in order to explore the coronary arteries and to examine the physiopathology of the disease. The studies revealed the presence of coronary lesions similar to ruptured plaques found in acute coronary syndromes. Although these findings should be completed with subsequent studies in a greater number of patients, they suggest that the physiopathological substrate of at least one subgroup of patients with Takotsubo syndrome is similar to acute coronary syndrome.
