Oxidative stress and inflammatory response are the main pathogenic pathways in atherosclerosis stenosis. This study is aimed at evaluating the roles of oxidative stress and inflammatory response in coexistent right carotid artery severe stenosis and severe multivessel coronary artery stenosis in elderly patients. Circulating levels of total oxidant status (TOS), lipid hydroperoxide (LHP), 8-isoprostane (8-IP), malondialdehyde (MDA), monocyte chemotactic protein-4 (MCP-4), amyloid A (AA), high-sensitivity C-reactive protein (hs-CRP), and tumor necrosis factor-α (TNF-α) were measured by standardised laboratory test methods. Markers of oxidative stress and inflammatory response: levels of TOS, LHP, 8-IP, MDA, MCP-4, AA, hs-CRP, and TNF-α, were increased ( P < 0.001 ) in elderly patient. These results suggested that oxidative stress and inflammatory response may be involved in carotid artery severe stenosis and severe multivessel coronary artery stenosis and measuring oxidative stress and inflammation biomarkers may also be a promising step in the development of an effective method for monitoring the severity of right carotid artery stenosis and multivessel coronary artery stenosis in elderly patients.

Background: Pro-inflammatory mediators and oxidative stress are related to severity of angina pectoris in patients with coronary heart disease. Objective: We evaluated the effects of pro-inflammatory mediators and oxidative stress on recurrent angina pectoris after coronary artery stenting in elderly patients. Methods: We determined the expression levels of malondialdehyde (MDA), acrolein (ACR), tumour necrosis factor-α (TNF-α), toll-like receptor 4 (TLR4), superoxide dismutase 3 (SOD3), paraoxonase-1 (PON-1), stromal cell-derived factor-1α (SDF-1α) and endothelial progenitor cells (EPCs) in elderly patients with recurrent angina pectoris after coronary artery stenting. Results: Levels of MDA, ACR, TNF-α and TLR4 were significantly increased (p<0.001), and levels of SOD3, PON-1, SDF-1α and EPCs were significantly decreased (p<0.001) in the elderly patients with recurrent angina pectoris after coronary artery stenting. MDA, ACR, TNF-α and TLR4 as markers of oxidative stress and pro-inflammatory mediators may have suppressed SOD3, PON-1, SDF-1α and EPCs as markers of anti-oxidative stress/anti-inflammatory responses. Oxidative stress and pro-inflammatory mediators were important factors involved in recurrent angina pectoris of elderly patients after coronary artery stenting. Conclusion: Oxidative stress and pro-inflammatory mediators could be considered as potential non-invasive prognostic, predictive and therapeutic biomarkers for stable recurrent angina and recurrent unstable angina in the elderly patients after coronary artery stenting.

Aim. To conduct the prospective study assessing the biochemical laboratory parameters in patients with stable angina and hemodynamically significant coronary artery stenosis before and 12 months after transluminal balloon-catheter angioplasty. Methods. 40 patients (males and females), mean age 57,3±9,6 years with stable angina and chronic coronary artery disease were examined. Patients were divided into 2 groups based on the absence (1st group, 14 patients) or presence (2st group, 26 patients) of hemodynamically significant coronary artery stenosis on selective coronary angiography. Patients with hemodynamically significant coronary artery stenosis underwent percutaneous transluminal coronary angioplasty (PTCA) with stenting (drug-coated stents). Blood lipid profile, inflammatory markers and endothelial dysfunction markers were measured before the surgery and 12 months after treatment. Results. In patients with hemodynamically significant coronary artery stenosis statistically significant association of hemodynamically significant coronary artery stenosis presence with atherogenic lipid fractions levels, inflammatory markers (high-sensitivity C-reactive protein, tumor necrosis factor-alpha) and an endothelial function parameter (endothelin-1) were revealed. Long-term results of PTCA with stenting included the significant decrease of atherogenic and increase of anti-atherogenic fractions in lipid profile. There also was a prolonged inflammatory response characterized by high-sensitivity C-reactive protein (hs-CRP) level elevation, and the endothelin system dysfunction retaining. Conclusion. Persistent hs-CRP level increase as well as endothelin-1 level increase suggest a high risk of late stent thrombosis, it should be taken into account while following-up patients at the late stages after PTCA.

It is now accepted that carotid artery stenosis should be treated as a part of systemic atherothrombosis. However, little is known about the association in atherosclerosis between the carotid and coronary arteries. We retrospectively investigated the association between carotid plaque vulnerability diagnosed on carotid magnetic resonance imaging (MRI) and coexisting coronary artery stenosis in patients scheduled for carotid endarterectomy (CEA) or carotid artery stenting (CAS). Eighty-nine consecutive cases that underwent carotid reconstruction for carotid artery stenosis at Kyoto University Hospital between 2010 and 2015 were enrolled in this study. Ten cases that received neither coronary angiography (CAG) nor coronary computed tomography angiography (CCTA) as preoperative examinations, 6 cases with restenosis after CEA or CAS, and 2 cases that did not undergo carotid MRI were excluded. We evaluated relative overall signal intensity (roSI) of the carotid plaque on T1-weighted imaging and coronary artery stenosis detected on CAG or CCTA in the remaining 71 cases. Carotid plaques with roSI >1.5 were defined as MRI-detected vulnerable plaques. Thirty-one cases had a history of previous coronary intervention (stenting or bypass surgery), of which 26 (84%) showed carotid vulnerable plaques. In the cases with no history of coronary intervention, coronary artery stenosis was newly detected in 21 cases, and was not demonstrated in the other 19 cases. Fifteen of the 21 cases with coronary artery stenosis (71%) also showed carotid vulnerable plaques. On the other hand, only 4 of the 19 cases without coronary artery stenosis (21%) had carotid vulnerable plaques, representing a significant difference (P<0.05). Among the cases with no history of coronary intervention, prevalence of coronary artery stenosis in cases with carotid vulnerable plaques was 79%, significantly higher than that in cases without carotid vulnerable plaques (29%). In conclusion, this study demonstrated that patients with carotid vulnerable plaques are more likely to have advanced coronary artery stenosis. Plaque characterization by carotid MRI is useful not only for treatment of carotid artery stenosis, but also for predicting coronary artery stenosis.
