超声心动图在评价冠状动脉旁路移植术患者疗效中的临床价值

摘要/Abstract

摘要： 目的:探讨超声心动图（IEE）检查在评价冠状动脉旁路移植术（CABG）患者疗效中的临床应用价值。方法：采取前瞻性研究模型，选取我院心内科2017年1月至2020年12月收治住院拟行CABG治疗的患者200例作为研究对象，根据SYNTAX 评分，分为中低SYNTAX 评分组（n=100）和高 SYNTAX 评分组（n=100）。比较分析两组患者治疗前及术后1个月、6个月超声心动图检查 E/A值和E/Ea值的变化。采用受试者工作特征曲线（ROC）评价E/A 和E/Ea预测高SYNTAX评分的诊断效能。结果：治疗前，高SYNTAX评分组患者E/A值低于中低SYNTAX评分组（P<0.05），E/Ea值高于中低SYNTAX评分组（P<0.05）。术后1个月，两组患者E/A值均高于同组治疗前（P<0.05），E/Ea值均低于同组治疗前（P<0.05）；高SYNTAX评分组E/A值低于中低SYNTAX评分组（P<0.05）。中低SYNTAX评分组E/A值在术后呈先升高再降低趋势（P<0.05），E/Ea值在术后呈先降低再升高趋势（P<0.05）。E/A、E/Ea两者联合预测CABG患者高SYNTAX评分具有较高的诊断价值。结论：超声心动图在评价冠状动脉旁路移植术患者疗效中具有一定的临床意义，术前及术后的超声心动图E/A值和E/Ea值水平变化对不同SYNTAX 评分CABG患者手术方案的选择及治疗效果评价具有一定的指导意义。

Abstract: Objective:To explore the clinical application value of echocardiography in evaluating the curative effect of coronary artery bypass grafting(CABG). Methods:The prospective research model was adopted. 200 patients who were admitted to the department of cardiology in our hospital and planned to undergo CABG treatment from January 2017 to December 2020 were selected as the research objects. According to SYNTAX scores, the patients were divided into the high SYNTAX score group and the middle and low SYNTAX score group, each group 100 cases. The echocardiographic E/A and E/Ea changes of the two groups of patients were compared and analyzed before CABG treatment and 1 month and 6 month after CABG treatment. The receiver operating characteristic(ROC) curve was used to evaluate the diagnostic efficacy of E/A and E/Ea in predicting high SYNTAX scores. Results:Before treatment, the E/A value of patients in the high SYNTAX score group was lower than that of the middle and low SYNTAX score group(P<0.05), and the E/Ea value was higher than that of the middle and low SYNTAX score group(P<0.05). The E/A value of the two groups of patients 1 month after operation was higher than that before treatment(P<0.05), and the E/Ea value was lower than that before treatment(P<0.05). The E/A value of patients in the high SYNTAX score group was lower than that of the middle and low SYNTAX score group at 1 month after operation(P<0.05). The E/A value of the middle and low SYNTAX score group showed a tendency of first increase and then decrease after the operation(P<0.05), and the E/Ea value first decreased and then increased after the operation(P<0.05). The combination of E/A and E/Ea has high diagnostic value in predicting high SYNTAX score in CABG patients. Conclusion: Echocardiography has certain clinical significance in evaluating the curative effect of CABG . The changes in the preoperative and postoperative echocardiographic E/A and E/Ea levels can provide certain guidance for the selection of surgical options and the evaluation of treatment effects for CABG patients with different SYNTAX scores.
