摘　　要：目的探讨冠心病患者运动负荷试验不同导联ST段下移的临床意义。方法选取2011年9月—2013年4月我院收治的冠心病患者45例,均先后行踏车运动试验及冠状动脉造影(CAG)检查。记录踏车运动试验中ST段出现阳性改变导联部位,CAG中相关冠状动脉病变指标,如病变支数、冠状动脉狭窄程度、Gensini积分分级。结果前壁导联组、下壁导联组和双导联组Gensini积分比较,差异无统计学意义(P>0.05)。相关分析结果显示,踏车运动试验出现ST段改变的部位分布情况与冠状动脉病变支数、狭窄程度、Gensini积分分级呈正相关(r值分别为0.338、0.342、0.310,P<0.05)。结论冠心病患者运动负荷试验中不同导联ST段下移与冠状动脉病变程度有一定的相关性,但尚不能评估冠状动脉病变程度。Objective To explore the significance of different ST segment depression of exercise stress test in patients with coronary disease. Methods 45 patients with coronary disease who were examined by exercise stress and CAG admitted to our hospital from September 2011 to April 2013 were analyzed. ST segment appearing positive positions, lesion count, coronary artery stenosis and Gensini score grading were recorded. Results Gensini score among anterior leads group, inferior leads group and double leads groups showed no significant difference （P 〉 0. 05 ） . ST segment change distribution was positively correlated with lesion count, coronary artery stenosis and Gensini score grading （r =0. 338, 0. 342, 0. 310, P 〈0. 05）. Conclusion ST segment depression of exercise stress test in diagnosis of patients with coronary disease has a certain correlation with coronary artery lesion, but the application value is poor for evaluating the severity of CtiD.
