Abstract
BackgroundThe interplay of tumour necrosis factor-α (TNF-α) and oxidative stress was related to severities of coronary atherosclerosis and congestive heart failure. We tried to identify TNF-α, soluble tumour necrosis factor-α receptor-1 (sTNFR-1), soluble tumour necrosis factor-α receptor-2 (sTNFR-2) and oxidative stress as potential non-invasive diagnostic and therapeutic biomarkers for coronary chronic total occlusion (CCTO) in the oldest patients with coronary heart disease (CHD). MethodsWe determined the expression levels of TNF-α, sTNFR-1, sTNFR-2, oxidative stress biomarkers (malondialdehyde [MDA], aldosterone [ALD], angiotensin II [Ang II], and high sensitivity C-reactive protein [hs-CRP]) in oldest patients with CCTO. ResultsThe levels of TNF-α, sTNFR-1, sTNFR-2, MDA, ALD, Ang II and hs-CRP were increased in oldest patients with CCTO (P < 0.001). The CCTO of oldest patients with CHD may involve the interplay of TNF-α, sTNFR-1, sTNFR-2 and oxidative stress. ConclusionsThe TNF-α, sTNFR-1, sTNFR-2 and oxidative stress could be considered as potential non-invasive diagnostic and therapeutic biomarkers for CCTO in the oldest patients with CHD.
