Abstract

Coronary artery ectasia (CAE) is the saccular or fusiform dilatation of a coronary artery. CAE is found in 1.2% to 4.9% of patients at autopsy or during angiographic studies, with a similar prevalence of CAE found in patients with atherosclerotic peripheral vascular disease (PVD). Abdominal aortic aneurysm (AAA) and CAE are similar in pathogenesis and histology. To determine whether CAE occurs more frequently in patients with AAA than in occlusive forms of atherosclerotic PVD, a review of coronary angiograms was pertormed in patients who underwent cardiac catheterization and vascular reconstruction for AAA or occlusive atherosclerotic PVD of the lower extremities. Of 72 patients with AAA, 15 had CAE (20.8%) compared with only 2 of 69 patients with atherosclerotic PVD (2.9%) (p < 0.003). CAE was predominantly discrete, located in the left coronary system, and associated with significant coronary atherosclerosis. CAE may be more prevalent in patients with AAA resulting from a similar pathogenetic process.
