摘要： 目的探讨应用三维斑点追踪技术(3D-STI)评价冠心病患者左前降支冠状动脉支架置入(PCI)术前、术后左室局部收缩功能。方法对30例接受左前降支PCl术的患者分别于术前、术后3～5天,术后3个月进行常规及三维超声心动图检查,获得患者左前降支冠状动脉供血的7个心肌节段(即前壁基底段、前间隔基底段、前壁中间段、前间隔中间段、前壁心尖段、前间隔心尖段及心尖帽)的收缩期纵向应变、径向应变、圆周应变及面积应变,分析冠状动脉支架植入术前、后各参数的变化规律。结果 PCI术后3～5天5/7节段纵向应变(前壁基底段、前壁中间段、前间隔基底段、前间隔中间段、前壁心尖段)、3/7节段面积应变(前壁基底段、前壁中间段、前间隔中间段)、3/7节段圆周应变(前壁基底段、前间隔基底段、前壁中间段)及2/7节段径向应变(前间隔基底段、前壁中间段)较术前相应心肌节段升高,差异有统计学意义(P＜0.05),PCI术后3个月左前降支供血各心肌节段纵向、圆周、径向及面积应变较术前、术后3～5天均升高,差异有统计学意义(P＜0.05)。结论 3D-STI能够早期评价冠心病患者左前降支冠状动脉PCI治疗前后左室局部收缩功能的改善,为临床早期评价PCI疗效及后续治疗提供诊断依据。

Abstract: Objective To evaluate the left ventricular regional systolic function before and after left anterior descending coronary artery stent implantation (PCI) using three-dimensional speckle tracking imaging (3D-STI) in patients with coronary artery disease. Methods 30 patients who received left anterior descending PCl were underwent routine and three-dimensional echocardiography before and after 3~5 days, 3 months to obtain longitudinal strain(LS), radial strain(RS), circumferential strain(CS)and area strain(AS) of the seven myocardial segments(BA,BAS,MA,MAS,AA,AS,A ),which accepted blood from the left anterior descending coronary artery. We analyzed the changes of the parameters before and after the coronary stent implantation. Results The 5/7 segment of the longitudinal strain(BA,MA,BAS,MAS,AA), 3/7 segment of area strain(BA,MA,MAS), 3/7 segment of circumferential strain (BA,BAS,MA)and 2/7 segment of radial strain (BAS,MAS)at 3~5 days after PCI were higher than that before the operation. The difference was statistically significant (P＜ 0.05). The longitudinal, circumferential, radial and area strain of the left anterior descending branch at 3 months after the operation were higher than that before and 3~5 days after the operation. The difference was statistically significant (P＜ 0.05). Conclusion 3D-STI may early evaluate the improvement of left ventricular regional systolic function before and after coronary artery PCI treatment in patients with coronary heart disease, and provide a basis for early clinical evaluation of PCI effect and follow-up treatment.
