Key result
Oxysterols link to fatty streaks and advanced lesions, correlating strongly with cholesterol.
Why the study?
Information on the oxysterol profile in human fatty streaks is limited compared to normal arteries and advanced atherosclerotic lesions.
Population
Necropsy samples of normal human arterial intima, intima with near-confluent fatty streaks, and advanced lesions
Comparison
Fatty streaks and advanced lesions vs normal human arterial intima
Design
Observational study with oxysterol quantification by GC and GC-MS

Oxysterol profiles in fatty streaks may inform early lesion biology; leaves open their causal role in atherosclerosis progression.
Observational
Oxysterols are present in fatty streaks and advanced atherosclerotic lesions but not normal arteries, suggesting multiple cholesterol oxidation mechanisms are involved in atherogenesis.
Garcia-Cruset et al. (2001) conducted an observational in Atherosclerosis. Atherosclerotic lesions (fatty streaks and advanced lesions) vs. Normal human arterial intima was evaluated on Oxysterol quantification. Oxysterols were present in fatty streaks and advanced lesions but very low in normal aorta, with a marked positive correlation between 27-hydroxycholesterol and cholesterol in fatty streaks.
