摘　　要：目的评价2DE检测RWMA在NSTEMI中的应用价值。方法 173例NSTEMI患者同期行2DE及CAG,2DE早于CAG。其中CAG阳性患者170例,以2DE检测有无RWMA分为2DE阳性组110例和2DE阴性组60例,并比较两组冠状动脉病变特点及行CAG治疗所占比例。结果 2DE检测RWMA对NSTEMI诊断的敏感度、特异度、阳性预测值、阴性预测值、准确性分别为64.7%、66.6%、99.1%、3.3%、64.7%;单支病变、双支病变、三支病变、IRCA平均狭窄程度、IRCA完全闭塞和次全闭塞、SYNTAX积分、需行CAG治疗的比例均有差异(P<0.05),但形成侧支循环比例无差异(P>0.05)。结论 2DE对NSTEMI诊断的敏感性较低,但应用2DE检测有无RWMA可初步辨别NSTEMI的冠状动脉病变的严重程度。Objective To evaluate the value of practical analyzing the RWMA of left ventricle by 2DE in NSTE- MI. Methods 173 patients were diagnosed as NSTEMI. All of them first accepted 2DE and then CAG. Among them, 170 CAG positive patients were divided into 2DE positive group（ 110 cases） and 2DE negative group（60 cases） accord- ing to whether or not RWMA detected by 2DE, and the characteristics of coronary artery disease and the proportion of CAG treatment were compared between the two groups. Results The sensitivity, speeifity, positive predictive value, nega- tive predictive value and accuracy of 2DE in diagnosing NSTEMI by the detection of RWMA is 64. 7% ,66. 6% ,99. 1%, 3.3% ,64.7% ;The results of CAG, single vessel disease, double vessel disease, triple vessel disease, mean stenosis degree of IRCA, IRCA complete occlusion and incomplete occlusion, the SYNTAX score, CABG treatment, are all signif- icant differences between the 2DE negative group and the 2DE positive group （ P 〈 0. 05 ）, collateral circulation formatted is no significant difference between them （ P 〉 0. 05 ）. Conclusions Though the accuracy of 2DE in diagnosing NSTEMI is not very high,we can estimate the stenosis degree of coronary artery by the detection of RWMA.
