近年来,越来越多的证据表明局部或全身炎症在冠状动脉粥样硬化及其斑块形成的发生、发展中起着重要作用,斑块的进展与炎症反应的程度密切相关[1]。作为炎性反应标志因子CRP,被认为与冠状动脉疾病的发生、发展和预后有着密切的关系,在预测斑块稳定性上有着较高的敏感性和精确性? In recent years, more and more evidences indicate that local or systemic inflammation plays an important role in the development of coronary atherosclerosis and plaque formation. The progress of plaque is closely related to the degree of inflammatory reaction [1]. As a marker of inflammatory response CRP, is thought to have a close relationship with the occurrence, development and prognosis of coronary artery disease, and has a high sensitivity and accuracy in predicting plaque stability.
