RODRIGUEZ-FERNANDEZ, Jairo; RANGEL, Alberto  and  CHAVEZ, Eduardo. Concurrence of myocardial infarction with Buerger's disease (Thromboangiitis obliterans): Report of a case. Arch. Cardiol. Méx. [online]. 2002, vol.72, n.4, pp.306-310. ISSN 1665-1731.

Background: Few cases of Buerger's disease concurring with visceral disorders, i.e., cardiac disease characterized by coronary obstruction have been published. We report the case of a 56 years old patient, with Buerger's disease concurring with ischemic heart disease: extensive anterior myocardial infarction, thrombosis, and obstruction of the left anterior descending coronary artery, evidenced through coronariography. Description of the case: Male patient, 56 years old, severe smoker since the age of 15, obese, normal blood pressure, carrier of Buerger's disease for 15 years, without symptoms or signs of rheumatic disorders, and negative immunological tests, with antecedents of an old extensive myocardial infarction secondary to diffuse disease of the left anterior descending artery. At present, with symptoms and signs of ischemic cardiopathy and angiographic images suggesting the presence of thrombi inside the anterior descending coronary artery, of gracile aspect (corkscrew image), severe and diffusely obstructed (80%), and poor distal vascular bed. Discussion: Causal association between Buerger's disease and coronary disease is rare and difficult to demonstrate in the absence of immunological and histopathological tests. Data provided by coronariography do not evidence a common origin for both diseases. However, the angiographic image of the gracile coronary artery, corkscrew-shaped, and with intraluminal thrombi suggests dissemination of the thromboangiitis to the coronary arterial bed. Conclusion: The concurrence of Buerger's disease with coronary pathology is rare. Coronary dissemination is difficult to demonstrate with only coronariography data; however, there are data in the medical literature suggesting that coronary obstruction, in these cases, results from the dissemination of the vasculopathy.
