许多研究证实,全身炎症的敏感标志物C反应蛋白(CRP)水平升高独立与冠心病及卒中危险相关,即支持炎症在动脉硬化病因中起重要作用的假说。同时研究亦表明,既往感染幽门螺杆菌(HP)、肺炎衣原体(CP)及巨细胞病毒(CMV)与冠状动脉、颈动脉或外周血管的动脉硬化相联系。本研究旨在明 Numerous studies have demonstrated that elevated levels of the C-reactive protein (CRP), a sensitive marker of systemic inflammation, are independently associated with coronary heart disease and the risk of stroke, a hypothesis supporting an important role for inflammation in the etiology of atherosclerosis. In the meantime, studies have also shown that previous infections with Helicobacter pylori (HP), Chlamydia pneumoniae (CP) and cytomegalovirus (CMV) are associated with atherosclerosis in the coronary, carotid or peripheral blood vessels. The purpose of this study is to clarify
