Sex Differences in Nonculprit Coronary Plaque Microstructures on Frequency-Domain Optical Coherence Tomography in Acute Coronary Syndromes and Stable Coronary Artery Disease

Abstract

Despite more comorbid risk factors in women, their nonculprit plaques exhibited more plaque erosion, and less cholesterol and calcium content. This distinct phenotype suggests sex-related differences in the pathophysiology of atherosclerosis.
