Coronary Artery Disease in Patients with Arteriosclerosis Obliterans of the Lower Extremities or Aortic Aneurysm

Routine coronary angiography was performed in order to determine the incidence and clinical condition of coronary artery disease in 37 patients with arteriosclerosis obliterans or aortic aneurysm. Coronary angiography demonstrated significant stenosis in 12 (57%) of 21 patients with arteriosclerosis obliterans and in 7 (44%) of 16 patients with aortic aneurysm. The prevalence of risk factors for arteriosclerosis was similar for patients with arteriosclerosis obliterans and those with aortic aneurysm, and similar for patients with and without coronary artery stenosis. But coronary artery disease is often silent in patients with arteriosclerosis obliterans. (Internal Medicine 31 :994−997, 1992)
