Sensitivity of 43% and specificity of 70% Pathophysiology: Microvascular disease of ear lobe which is end artery territory Grading system for severity of CAD                • Unilateral incomplete – least severe                • Unilateral complete                • Bilateral complete – most severe                Other classifications systems exist, but without the association with
