摘　　要：为探讨二维应变超声(2D-STI)对冠心病介入治疗前后左室心肌功能的评价效能,选取成功实施经皮冠状动脉介入术(PCI)的冠心病患者50例为PCI组,健康体检者50例为对照组,比较两组患者常规超声、2D-STI检查情况。结果显示,与对照组比较,PCI组术前A峰明显增高(P<0.05)、E/A值及LVEF降低(P<0.05)。PCI组术后LVEF及术后60 d、术后180 d的E/A值均高于术前(P<0.05),而术后180 d的LVEF高于术后30 d(P<0.05)。PCI组术前GLS、GRS及GCS水平低于对照组(P<0.05),术后GLS、GRS及GCS水平均较术前增高(P<0.05),术后180 d GRS、GCS较术后30 d进一步增高(P<0.05),但术后各时点水平低于对照组(P<0.05)。GLS、GCS与LVEF呈负相关(P<0.05),GRS与LVEF呈正相关(P<0.05)。说明2D-STI对冠心病介入治疗前后患者左室心肌功能有一定评估价值。To investigate the application value of 2D-STI in evaluating the left ventricular muscle function before and after PCI in patients with coronary heart disease,fifty patients with coronary heart disease(PCI group)who underwent PCI successfully were selected as PCI group,fifty healthy patients were taken as control group.The ultrasound indicators,2D-STI parameters were compared in the two groups.The results showed,compared with the control group,the preoperative A peak elevated(P<0.05),E/A value and LVEF in the PCI group reduced(P<0.05).In the PCI group,LVEF postoperative and E/A at 60 d,180 d after surgery was higher than that before surgery(P<0.05),and LVEF at 180 d after surgery was higher than that at 30 d after surgery(P<0.05).The levels of GLS,GRS and GCS before surgery in the PCI group were lower than those in the control group(P<0.05),and the levels of GLS,GRS and GCS after surgery were higher than those before surgery(P<0.05),GRS and GCS were further increased at 180 d after surgery compared with 30 d after surgery(P<0.05).The levels of GLS,GRS and GCS in the PCI group were lower than those in the control group at each time point after surgery(P<0.05).GLS and GCS were negatively correlated with LVEF(P<0.05),while GRS was positively correlated with LVEF(P<0.05).The results indicated that 2D-STI can be used to evaluate left ventricular myocardial function after interventional treatment of coronary heart disease.
