Color Kinesis在识别心梗后存活心肌及判断冠脉病变的应用研究
目的:本研究将Color Kinesis(CK)与多巴酚丁胺超声心动图负荷试验(DSE)相结合,检测急性心肌梗塞(AMI)后存活心肌及冠脉病变.方法:左室采用16节段分法,室壁运动状态采用4级分法.存活心肌以PTCA 2周后二维超声心动图(2DE)与DSE BASE状态2DE的比较结果作为参考标准;冠脉病变以冠脉造影结果作为金标准.结果:CK-DSE检测冠脉病变及存活心肌敏感性高于2DE(95.0% vs 82.5%,87.0% vs 78.3%),特异性与2DE相当(75.0% vs 79.2%),CK对LCX病变仍有很高的敏感性(90.9%).结论:CK能及时准确地检出AMI存活心肌及冠脉病变.

彩色室壁运动显像评价冠心病患者康复训练后心功能的研究
Background: Ultrasound cardiogram plays an important role in evaluating cardiac function of patients with coronary heart disease before and after rehabilitation.Wall motion,function of contraction,and cardiac function could be evaluated using ultrasound cardiogram.Sensitivity of visual method in evaluating wall motion is not high.Color kinesis(CK) is a kind of new technology.Objective: To study sensitivity and accuracy of CK and visual method in evaluating wall motion.Design: In order to test sensitivity of CK,we compared CK and visual method.Unit: General Hospital of Shenyang Military Region Subjects:120 patients suffered from coronary heart disease during 1998～ 2000,78 male,42 female,aged from 36～ 72 years(mean:54 years).All patients had history of precardial pain,and ST-T changes were found in ECGs.Intervention: Coronary arteriography was done on all patients.To observe wall motion using visual method and CK.Color Doppler inspector HP2500 with a probe(2.5MHz/2.0MHz).Patients lied in horizional position.Then CK examination was done after defining endocardium.Simularly,electrographic signals were recorded.Endocardial motion were numbered colorfully.
