【摘要】：目的探讨实时三维超声心动图(RT-3DE)对经皮冠状动脉介入术(PCI)后患者支架内再狭窄(ISR)的诊断价值。方法对100例接受PCI治疗的单纯左前降支受累患者,于PCI术前3d及术后半年行RT-3DE检查,获得左室前壁及前室间隔基底段、中间段、心尖段PCI术前、后平均舒张末期容积比(rEDV′%)、平均收缩末期容积比(rESV′%)、不同步节段数比(DS%)。以冠脉CT检查(CTA)为金标准,分析rEDV′%、rESV′%及DS%诊断ISR的准确度。结果 (1)ISR组患者PCI术前、后rEDV′%、rESV′%差异无统计学意义(P0.05);正常组患者PCI术前、后rEDV′%、rESV′%差异有统计学意义(P0.05)。(2)ISR组与正常组rEDV′%、rESV′%、DS%比较,差异有统计学意义(P0.05)。(3)ROC曲线显示:rEDV′%、rESV′%、DS%3项参数对ISR的诊断价值比较大。结论 RT-3DE通过测量计算的rEDV′%、rESV′%,是评估PCI术后ISR的有效指标。
[Abstract]:Objective to evaluate the diagnostic value of real-time three dimensional echocardiography (RT-3 DEE) in patients with restenosis after percutaneous coronary intervention (PCI). Methods 100 cases of simple left anterior descending branch involvement treated with PCI were examined with RT-3DE 3 days before and half a year after PCI. The left ventricular anterior wall, basal segment of anterior ventricular septum, middle segment and apical segment of left ventricle were obtained before PCI. The mean end-diastolic volume ratio (REDV), the mean end-systolic volume ratio (rESVV), and the number of non-synchronous segments were greater than that of DSV. The diagnostic accuracy of rESVV% and DS% in diagnosis of ISR was analyzed using coronary CT scan as the golden standard. Results there was no significant difference in rESVV% between the two groups before PCI, and there was no significant difference in rESV% between the normal group and the normal group before PCI, and there was a significant difference between the latter group and the normal group in the DS% of the rESVV between the P0.05 group and the normal group, and there was no significant difference between the two groups in the two groups (P < 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, P < 0. 05). The difference was statistically significant (P 0.05). The ROC curve showed that the diagnostic value of the three parameters of REDV in the diagnosis of ISR was higher. Conclusion RT-3DE is an effective index for evaluating ISR after PCI.
