| 目的：探讨超声斑点追踪成像技术定量评价冠状动脉搭桥术前、后心肌功能的临床价值。方法：选择2012 年1 月～2013 年
1 月在我院心脏外科行体外循环下冠状动脉旁路移植术的患者，对冠状动脉搭桥术术前1 周、术后1 月、3 月、6 月进行常规超声
心动图检查，然后应用斑点追踪技术进行分析。结果：所有患者的纵向应变值仅在术后3 个月和6 个月显著增加，与术前、术后1
个月比较差别有统计学意义(P<0.01)。圆周应变值在术后1个月、3 个月和6 个月均显著增高，与术前比较差别有统计学意义(P<0.
05)。老年组术后6 个月的纵向应变值和圆周应变值与术后3 个月比较差别有统计学意义(P<0.05)。手术前、后常规超声心动图检
查结果比较差别无统计学意义(P>0.05)。结论：超声斑点追踪技术用于评估CABG 术后缺血心肌的功能变化的敏感性高于常规超
声心动图检查，为临床评价CABG的疗效提供了一种新方法。 |

| Objective:To investigate the clinical significance of speckle tracking imaging in the quantitative evaluation of myocardial
function of patients after coronary artery bypass graft surgery (CABG).Methods:In this study, patients who underwent CABG in the
department of cardiac surgery fromJanuary 2012 to January 2013 were selected, all the patients (left ventricular ejection fraction ≥ 50%)
were classified into two groups based on the age: elderly group(>60 years old) and non-elderly group(≤ 60 years). The conventional
echocardiography, longitudinal strain and circumferential strain were measured by STI analysis 1 week before CABG and 1, 3, 6 months
after CABG.Results:The longitudinal strain increased significantly at 3 and 6 months after CABG compared with that pre-operation(P＜
0.05). The circumferential strain of both groups increased significantly at 1, 3 and 6 months after CABG, compared with that baseline
(P＜0.05). But in the elderly group, the longitudinal strain and circumferential strain increased significantly at postoperative 6 month
compared with that postoperative 3 month (P<0.05). However, no significant difference was found in the left ventricular end-diastolic dimension(
LVEDd), left ventricular ejection fraction(LVEF) and stroke volume(SV) measured by routine echocardiography between preand
post-CABG (P＞0.05).Conclusion:Speckle tracking technology was more sensitive to evaluate the myocardial function after CABG
than conventional echocardiography, and provided a new method for the evaluation of CABG efficacy in clinic. |
