Key result
Combined severe carotid and coronary artery stenosis was associated with remarkably increased levels of oxidative stress and inflammatory markers (P < 0.001).
Why the study?
Dynamic changes of circulating oxidative stress and inflammatory markers in carotid stenosis combined with coronary artery stenosis were unclear, and whether they represent potential therapeutic targets remained unknown.
Are markers of oxidative stress and inflammation elevated in patients with combined severe carotid and coronary artery stenosis?
Observational

p-value: p=<0.001
Biomarkers of oxidative stress and inflammation are significantly elevated in patients with combined severe carotid and coronary artery stenosis, suggesting potential utility for disease assessment.
Suggests these biomarkers may aid in assessing polyvascular disease severity; leaves open whether targeting this.
INTRODUCTION: Patients with left carotid artery atherosclerotic stenosis have an increased ischemic stroke risk. Left carotid stenosis, the most common cause of the transient ischemic attack, is related to a higher risk of acute stroke. Left carotid artery stenosis is also associated with cerebral artery infarction. The significant coronary stenosis promotes ST-segment elevation myocardial infarctions. The severe coronary stenosis plays an important role in development and progression of myocardial infarction. However, the dynamic changes of circulating oxidative stress and inflammatory markers in the carotid stenosis combined with coronary artery stenosis are not clear, and it also remains unknown whether mark of oxidative stress and inflammation are potential therapeutic targets for carotid stenosis combined with coronary artery stenosis. AIM: This study aims to explore the effects of oxidative stress combined with an inflammatory response on left carotid artery stenosis with coronary artery disease in patients. METHODS: We, therefore, tested the hypothesis that levels of markers of oxidative stress and inflammation are associated with coexistent severe carotid and coronary artery stenosis in patients. We measured the circulating levels of malondialdehyde (MDA), oxidized low-density lipoprotein (OX-LDL), homocysteine (Hcy), F2- isoprostanes (F2-IsoPs), tumor necrosis factor-alpha (TNF-α), high-sensitivity C-reactive protein (hs-CRP), prostaglandin E2 (PG-E2) and interferon-gamma (IFN-γ) in patients with combined carotid and coronary artery severe stenosis. We also assessed the relationships among oxidative stress, inflammation, and severe stenosis of the carotid with a coronary artery in patients. RESULTS: Levels of MDA, OX-LDL, Hcy, F2-IsoPs, TNF-α, hs-CRP, PG-E2, and IFN-γ were remarkably increased (P < 0.001) in patients with combined carotid and coronary artery severe stenosis. High levels of oxidative stress and inflammation may be related to severe stenosis of the carotid with coronary arteries in patients. CONCLUSION: Our observations indicated that measurements of oxidative stress and inflammatory markers may be valuable for the assessment of the degree of carotid with coronary artery stenosis. The biomarkers of oxidative stress and inflammatory response may become therapeutic targets for carotid artery stenosis with coronary artery stenosis in patients.

Li et al. (2023) conducted an observational in Left carotid artery stenosis with coronary artery disease. Combined carotid and coronary artery severe stenosis was evaluated on Levels of oxidative stress and inflammatory markers (MDA, OX-LDL, Hcy, F2-IsoPs, TNF-α, hs-CRP, PG-E2, and IFN-γ) (p=<0.001). Combined severe carotid and coronary artery stenosis was associated with remarkably increased levels of oxidative stress and inflammatory markers (P < 0.001).
