目的:探讨组织同步显像(TSI)对尿毒症性心肌病患者左心室非同步性的价值.方法:采用TSI技术对35例尿毒症性心肌病患者与对照组30例进行左室同步性检测,获取左心室各节段心肌长轴方向的组织运动图像,测量各节段达峰值速度时间T(经心率校正后为TC).结果:(1)尿毒症组各节段的总达峰时间以及平均达峰时间均延迟(P<0.05),大部分节段(主要为中间段,106中间段对69基底段)达峰时间较对照组延迟(P<0.05);(2)尿毒症组表现为黄色或红色的达峰时间延迟共175(175/420)节段,心肌节段收缩延迟在尿毒症组发生率为65 7;(23/35).结论:TSI可发现尿毒症性心肌病收缩非协调性,对早期诊断有较好价值,为临床综合治疗提供理论依据.
Objective: To evaluate the left ventricular systolic asynchrony in patients with uremic myocardiopathy(UM) using tissue synchronization imaging(TSI). Methods: Ultrasound system with TSI and Q-analyze software were used.Thirty-five patients with UM were enrolled in the study,and thirty normal subjects were included as the control group. Results: The total and mean time to peak velocity(TC) corrected by the heart rate of all segments in UM group were longer than those in the control group (P<0.05),and the time to peak velocity of most segments in UM group was also longer (P<0.05). Delayed time to peak velocity was found in 175(175/420) segments in UM group and left ventricular systolic asynchrony was detected in 65.7;(23/35). Conclusion: TSI can detect the ventricular systolic asynchrony in patients with uremic myocardiopathy and provide reliable parameters for clinical management.
