MARIN-OYAGA, Víctor; FRANCO-REYES, Camilo; BUITRAGO-GOMEZ, Adriana  y  GUTIERREZ-VILLAMIL, Claudia. Suspected changes in isotopic study of myocardial perfusion in patients with Chagas disease and normal epicardial coronary arteries. Rev. Colomb. Cardiol. [online]. 2017, vol.24, n.5, pp.512-512.  Epub 05-Ene-2017. ISSN 0120-5633.

Chagas disease is a parasitic entity caused by Tripanosoma cruzi with a high prevalence in America, mostly in Latin America. Its indeterminate phase lasts between 10 and 30 years. Within this period patients do not show symptoms and can migrate to anywhere in the world.

The most relevant consequence is chagasic cardiomyopathy with different manifestations. Many times the initial sign of this cardiomyopathy is cardiac insufficiency in a dilated heart, which on occasion makes it imperative to rule out an ischemic component. Myocardial perfusión scintigraphies are a useful tool to study myocardial ischemia, their high sensitivity allows to observe diverse perfusion defects, even in the absence of atherosclerotic coronary disease. This study presents the case of a male patient with chest pain and Chagas disease showing multiple perfusion defects of microvascular origin in the myocardial perfusion scintigraphy, evidencing healthy epicardial coronary arteries.
