    Abstract:
    Smoking is a risk factor for thromboangiitis obliterans (TAO, Buerger's disease) and arteriosclerosis, but there are few cases of coronary heart disease (CAD)-associated Buerger's disease. A literature search for articles in English, Spanish and French published between 1966 and 2012 on patients with coronary involvement and TAO revealed 12 patients. We describe an additional case with involvement of the central nervous system, myocardium and large-diameter proximal arteries. The main clinical manifestations in these 13 cases were lower limb claudication and acute thoracic pain. The histologic findings showed thrombosis with unbroken internal elastic lamina and intimal clusters of granulocytes; coronary angiography revealed predominant involvement of the left anterior descending and right coronary artery. Treatment included coronary bypass procedures, coronary angiopiasty, smoking cessation, and anticoagulant therapy. A complete therapeutic response was observed in half the patients. This review of all published cases of TAO patients with coronary symptoms, together with our patient, demonstrates the rarity of this clinical association. Patients under age 40 with CAD but no prominent cardiovascular risk factors besides smoking should be evaluated for the presence of Buerger's disease.
