【摘要】：目的探討實(shí)時(shí)三維超聲心動圖(RT-3DE)評價(jià)心肌梗死患者左心室收縮功能及同步性的應(yīng)用價(jià)值。方法選取67例心肌梗死患者(心梗組)及61名健康志愿者(正常組)分別接受RT-3DE、M型超聲及二維超聲檢查,心梗組分為3個亞組,A亞組:左冠狀動脈狹窄(n=19)、B亞組:右冠狀動脈狹窄(n=28),C亞組:多支病變(n=20)。分析比較3種方法所測以下參數(shù):左心室整體、局部舒張末期容積(gEDV、rEDV),整體、局部收縮末期容積(gESV、rESV),整體、局部射血分?jǐn)?shù)(gEF、rEF);左心室16節(jié)段從QRS波起點(diǎn)到最小收縮容積時(shí)間的標(biāo)準(zhǔn)差和最大差值(Tmsvl6-SD、Tmsvl6-Dif)。結(jié)果 M型超聲、Simpson法所測的gEDV、gESV均高于RT-3DE(P均0.05)。以gEF55%作為判斷收縮功能降低的截?cái)帱c(diǎn),M型超聲、Simpson法、RT-3DE診斷心肌梗死的敏感度與特異度分別為96%和43%、98%和52%、98%和64%。RT-3DE局部心功能分析:與正常組對應(yīng)節(jié)段比較,A亞組主要為前壁、前間隔,B亞組側(cè)壁、下后壁、后間隔,C亞組絕大多數(shù)節(jié)段EDV、ESV增加,EF降低(P均0.05)。心梗組Tmsvl6-SD、Tmsvl6-Dif、Tmsvl6-SD%、Tmsvl6-Dif%均大于正常組(P均0.05)。結(jié)論 RT-3DE能更客觀、準(zhǔn)確地評價(jià)心肌梗死患者的收縮功能及室壁運(yùn)動同步性,且能逐個節(jié)段進(jìn)行局部定量分析,為臨床提供更加全面可靠的參考信息。
[Abstract]:Objective to evaluate the value of real-time three-dimensional echocardiography (RT-3DE) in evaluating left ventricular systolic function and synchronism in patients with myocardial infarction. Methods 67 patients with myocardial infarction (MI group) and 61 healthy volunteers (normal group) were selected. Do not accept RT-3DEM-mode ultrasound and two-dimensional ultrasound examination, Myocardial infarction group was divided into 3 subgroups: left coronary artery stenosis group: left coronary artery stenosis group: right coronary artery stenosis subgroup C: multivessel lesion. Analysis and comparison of the following parameters measured by three methods: left ventricular whole, local end-diastolic volume: gEDVrEDV, whole, whole, and so on, the left ventricle, the left ventricle, the left ventricular end diastolic volume, the left ventricular end diastolic volume, the whole, the left ventricular stenosis, the right coronary artery stenosis, the right coronary artery stenosis and the right coronary artery stenosis. Local end-systolic volume / rESVN, whole, The standard deviation and maximum difference of left ventricular 16 segments from the beginning of QRS wave to the minimum systolic volume time were measured by Tmsvl6-SDT Tmsvl6-Difanf.Results the gEDV / gESV measured by M-mode ultrasound / Simpson method was higher than that of RT-3DE(P (0.05%). The sensitivity and specificity of RT-3DE in diagnosing myocardial infarction were 96% and 439.98% and 52.98% and 64.RT-3DE, respectively. In the anterior septal subgroup B subgroup, the majority of segmental EDV EDV ESV increased and EF decreased (P < 0.05). The Tmsvl6-SDV Tmsvl6-SDF Tmsvl6-SDF% in the myocardial infarction group was higher than that in the normal group (P < 0.05). Conclusion the RT-3DE is more objective, and it is more objective than that of the normal control group (P < 0.05), and the ratio of Tmsvl6-SDN to Tmsvl6-SDV is higher than that of the normal group (P < 0.05). The systolic function and the synchronism of ventricular wall motion in patients with myocardial infarction can be evaluated accurately, and the local quantitative analysis can be carried out one by one, which can provide more comprehensive and reliable reference information for clinical practice.
