Elevated lipid profile and reduced antioxidants accelerate the formation of atherosclerosis. Multiple lines of evidences have suggested that increased lipids and low antioxidants are the major risk factors for the incidence of acute coronary syndrome. Oxidative stress evaluation is now considered as an index for the assessment of development of coronary artery disease. Therefore, we studied association of the levels of non-enzymic antioxidants and lipid profile in controls and patients with acute coronary syndrome (ACS).
The present study was carried out on 485 patients admitted to the emergency care unit, of whom 89 patients were diagnosed as non-cardiac chest pain (NCCP). Total cholesterol, LDL-cholesterol, HDL-cholesterol and triglycerides were analysed along with non-enzymic antioxidants such as vitamin C, vitamin E, reduced glutathione, MDA and protein thiol in controls and patients with ACS. The levels of total cholesterol and LDL-cholesterol were significantly raised in patients when compared to controls in contrast to lowering of HDL-cholesterol levels in patients than controls. Vitamin C, vitamin E, reduced glutathione, MDA and protein thiol levels were significantly lowered in patients than controls (p<0.05).
Oxidative stress and lipid profile should be included as important markers in the early detection of acute coronary syndrome.
血脂升高和抗氧化剂减少会加速动脉粥样硬化的形成。有多项证据表明,血脂升高和抗氧化剂水平降低是急性冠状动脉综合征发病的主要危险因素。氧化应激评估现被认为是评估冠状动脉疾病发展的一个指标。因此,我们研究了非酶抗氧化剂水平与急性冠状动脉综合征(ACS)患者和对照组之间的关系。
本研究共纳入 485 名入住急诊病房的患者,其中 89 名被诊断为非心源性胸痛(NCCP)。在对照组和 ACS 患者中分析了总胆固醇、LDL-胆固醇、HDL-胆固醇和甘油三酯以及非酶抗氧化剂,如维生素 C、维生素 E、还原型谷胱甘肽、MDA 和蛋白巯基。与对照组相比,患者的总胆固醇和 LDL-胆固醇水平显著升高,而患者的 HDL-胆固醇水平则低于对照组。与对照组相比,患者的维生素 C、维生素 E、还原型谷胱甘肽、MDA 和蛋白巯基水平显著降低(p<0.05)。
氧化应激和血脂谱应作为急性冠状动脉综合征早期检测的重要标志物。
