ABSTRACT
OBJECTIVES: To assess the prognostic significance of high vs. low grade coronary artery ectasia (CAE) and the impact of antithrombotic or anticoagulant therapy on adverse cardiac outcomes. BACKGROUND: There is paucity of knowledge on the impact of angiographic characteristics in CAE or that of antithrombotic or anticoagulant therapy on outcomes. METHODS AND RESULTS: In this retrospective study, we reviewed angiograms and medical records of all cases of confirmed CAE (2001-2011). Extent of CAE was categorized using the Markis classification. Types 1 and 2 were categorized as high-grade and types 3 and 4 as low-grade CAE. Angiographic flow was recorded as normal or sluggish (Subject(s)
