摘要
目的 :对彩色室壁动力分析 (CK)技术检测冠心病心肌梗死存活心肌的能力进行探讨。方法 :将 CK与小剂量多巴酚丁胺负荷试验 (DE)相结合 (CK- DE)对 1 4例冠心病心肌梗死的患者进行 DE。结果 :以单光子发射计算机断层显像作为“金标准”对照分析 1 82个节段 ,二维超声心动图(2 DE) DE试验 (2 DE- DE)和 CK- DE试验判断存活心肌的敏感性、特异性、阳性预测值和阴性预测值分别为 86%、65%、76%、79%和 91 %、75%、84%、87% (P<0 .0 5～ 0 .0 1 )。结论 :CK- DE试验判断存活心肌时其敏感性、特异性均较 2 DE- DE试验好 ,有较高的临床实用价值。
Objective: The purpose of this study was to evaluate the ability of identifying viable myocardiun by colorkinesis(CK).Method:We studied fourteen cases with coronary artery diseases after acute myocardial infarction. Akinetic or hypokinetic segment was considered viable by CK DE if dobutamine induced color increment could be observed. The results were compared with SPECT in one to three days. Result:One hundred and eight two segments were analyzed by 2D DE and CK DE. The sensitivity, specificity, positive predictive and negative predictive values of 2D DE and CK DE for identifying viability were 86%,65%,76%,79% and 91%,75%,84%,87%(P< 0.05 ～ 0.01 ).Conclusion:The sequential color border display makes it easier to see the endocardial borders, facilitating the qualitative scoring of wall motion. CK DE provides a promising low cost and widely available approach to reveal residual myocardial viability in patients with acute and chronic myocardial infarction.
