Single Blind Randomized Study to Determine the Sensitivity and Specificity of 2 Non-invasive Markers of Early Coronary Disease

McGill University Health Centre/Research Institute of the McGill University Health Centre10 enrolled

Overview

Diagonal ear lobe crease and microcirculatory disorder in the conjunctiva are both non invasive methods documented in the literature as early signs of coronary artery disease. We wish to study the sensitivity and specificity of both signs by conducting a single blind study involving patients with documented presence or absence of coronary artery disease via angiogram.
