    Clinical utility of quantitative bright spots analysis in patients with acute coronary syndrome: an optical coherence tomography study

    To investigate the clinical significance of bright spots in coronary plaque detected by optical coherence tomography (OCT) in patients with coronary artery disease. We identified 112 patients [acute coronary syndromes (ACS): n = 50, stable angina pectoris (SAP): n = 62] who underwent OCT imaging of the culprit lesion. A novel OCT algorithm was applied to detect bright spots representing the juxtaposition of a variety of plaque components including macrophages. The density of bright spots within the most superficial 250 μm of the vessel wall was measured at the site of culprit lesion. Bright spot density in the culprit lesion was significantly ...
