Implication

ROS contribution to vasculopathy supports mechanistic research; leaves open whether targeted antioxidants alter clinical outcomes.

Key Points

To review the mechanisms by which free radical-induced oxidative stress and reactive oxygen species contribute to endothelial injury and the progression of coronary artery disease.
Synthesized biomedical literature investigating the cellular mechanisms of reactive oxygen species in vascular pathogenesis.
Evaluated pathophysiological pathways connecting low-density lipoprotein oxidation, endothelial dysfunction, and smooth muscle impairment to atherogenesis.
Demonstrated that reactive oxygen species directly impair endothelial cell integrity, triggering macrophage infiltration and vascular smooth muscle dysfunction.
Identified low-density lipoprotein oxidation and its endothelial interaction as the primary injury driving fatty streak formation and atherogenesis.
Showed that diverse reactive oxygen species produced in the vessel wall promote cardiovascular disorders both individually and cooperatively.

Exposure / Comparator

Reactive oxygen species (ROS) / Oxidative stress

Oxidative stress and reactive oxygen species play a fundamental role in endothelial damage, LDL oxidation, and the subsequent development of coronary artery disease.
