BACKGROUND: Pro-inflammatory mediators and oxidative stress are related to the 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 proinflammatory 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 noninvasive prognostic, predictive, and therapeutic biomarkers for stable recurrent angina and recurrent unstable angina in elderly patients after coronary artery stenting.
