    摘 要:目的 探讨冠状动脉支架置入后肌钙蛋白-I水平同术前冠状动脉粥样硬化斑块负荷的关系及评估冠心病患者的病情和判断预后. 方法 对完成PTCA术、术前cTnI均正常的285例患者，按术后cTnI值将患者分为正常组、中间组、增高组.使用3种血管计分法对冠状动脉硬化程度进行计分，将3种方法的计分值分别同cTnI值进行相关性分析. 结果 支架置入后总的cTnI升高率为80.7%，高于国外报道的比例.支架置入术后的cTnI值同范围计分间存在着密切关系(r=0.763，P<0.01)，与狭窄计分和病变血管支数计分间无相关.增高组患者弥漫性病变广泛、术后低血压和缓慢性心率的发生率较高.弥漫性病变的cTnI值较高. 结论 支架置入术后cTnI值反映了术前基础血管硬化程度.
