Value analysis of transthoracic real-time three-dimensional ultrasound visualization model in diagnosis of coronary heart disease and vascular localization of lesions

摘要:

目的 分析在冠状动脉粥样硬化性心脏病（以下简称冠心病）诊断及病变血管定位中经胸实时三维超声可视化模型的应用价值。方法 选取2017年10月—2019年5月重庆三峡中心医院疑似冠心病并接受经胸实时三维超声可视化模型诊断者128例进行回顾性分析，均实施冠状动脉造影检查，并将其检查结果作为“金标准”，明确经胸实时三维超声可视化模型诊断冠心病及病变血管定位结果，并明确其诊断结果及病变血管定位诊断结果与“金标准”的一致性。结果 经冠状动脉造影检查发现，本组受检者中67例冠心病患者，其中有63例经胸实时三维超声可视化模型拟诊断为冠心病，在61例冠状动脉造影检查诊断为非冠心病的患者中有2例经胸实时三维超声可视化模型拟诊断为冠心病；冠脉造影检查诊断为冠心病的67例患者中有196处血管病变，其中左前降支、左回旋支、右冠脉血管病变占比分别为49.24%、30.46%和20.30%，经胸实时三维超声可视化模型拟诊断为冠心病的65例受检者中共发现193处血管病变，其中定位左前降支、左回旋支、右冠脉血管病变结果与冠脉造影检查的符合率分别为97.94%、98.33%和97.50%，整体符合率为97.97%；两种方法诊断冠心病结果、病变血管定位结果的一致性均较好（P <0.05）。结论 经胸实时三维超声可视化模型可准确诊断冠心病，并定位病变血管，且其结果与冠状动脉造影有较好的一致性。

Abstract:

Objective To explore and analyze the application value of real-time three-dimensional transthoracic ultrasound visualization model in the diagnosis of coronary heart disease and the localization of lesion vessels.Methods A retrospective analysis was made of 128 electronic medical records of suspected coronary heart disease (CHD) patients admitted to the hospital from October 2017 to April 2019 and diagnosed by real-time three-dimensional ultrasound visualization model through thorax. Coronary angiography was performed in all patients, and the results were regarded as the "gold standard". The results of real-time three-dimensional transthoracic ultrasound visualization model in diagnosis of coronary heart disease and localization of lesion vessels were determined. The consistency of the diagnostic results and the localization of the lesion vessels to the "golden standard" was defined.Results Coronary angiography revealed 67 patients with coronary heart disease, of whom 63 were diagnosed as coronary heart disease by real-time three-dimensional echocardiographic visualization model. Among 61 patients diagnosed as non-coronary artery disease by coronary angiography, 2 patients were diagnosed as coronary artery disease by real-time three-dimensional ultrasound visualization model. A total of 196 vascular lesions were found in 67 patients with coronary heart disease diagnosed by coronary angiography. The proportion of left anterior descending artery, left circumflex artery, and right coronary artery lesions were 49.24%, 30.46%, and 20.30%, respectively. A total of 193 vascular lesions were found in 65 patients with coronary artery disease who were supposed to be diagnosed by real-time three-dimensional ultrasound visualization model. The coincidence rates of localization of left anterior descending artery, left circumflex artery, and right coronary artery lesions with coronary angiography was 97.94%, 98.33%, 97.50%, and the overall coincidence rate was 97.97%. The consistencies of the two methods in diagnosing coronary artery disease and locating the lesion vessels were satisfied (P < 0.05).Conclusion Real-time three-dimensional ultrasound visualization model can accurately diagnose coronary heart disease and locate the lesion vessels, with satisfied consistency.
