【摘要】：目的探討應(yīng)用實時三維超聲心動圖(RT-3DE)評價急性心肌梗死患者經(jīng)皮冠狀動脈介入治療(PCI)前后左心室局部功能變化的應(yīng)用價值。方法選取2012年12月—2013年12月佳木斯大學(xué)附屬第一醫(yī)院接受PCI的急性心肌梗死患者46例為病例組,其中下后壁心肌梗死組27例,下壁心肌梗死組19例;另選擇同時期體檢中心體檢健康者30例為對照組,對照組于體檢時,病例組于PCI前、PCI后1、4、12周分別做RT-3DE檢查,記錄左心室各節(jié)段舒張末期容積(r EDV)及左心室各節(jié)段收縮末期容積(r ESV),并計算出各節(jié)段射血分?jǐn)?shù)(r EF)。結(jié)果對照組RT-3DE左心室各節(jié)段容積-時間曲線規(guī)整有序,病例組患者PCI前RT-3DE左心室各節(jié)段容積-時間曲線雜亂無序。對照組與下后壁心肌梗死組PCI前及PCI后1周下壁基底段、下壁中間段、下壁心尖段、后壁基底段、后壁中間段r EF比較,差異有統(tǒng)計學(xué)意義(P0.05);對照組與下后壁心肌梗死組PCI后4周下壁中間段、后壁中間段r EF比較,差異有統(tǒng)計學(xué)意義(P0.05)。下后壁心肌梗死組患者PCI前、PCI后1周、PCI后4周及PCI后12周下壁基底段、下壁中間段、下壁心尖段、后壁基底段、后壁中間段r EF比較,差異有統(tǒng)計學(xué)意義(P0.05);其中PCI后1周后壁中間段r EF較PCI前升高(P0.05);PCI后4周及PCI后12周下壁基底段、下壁中間段、下壁心尖段、后壁基底段、后壁中間段r EF較PCI前及PCI后1周升高(P0.05);PCI后12周下壁中間段、后壁中間段r EF較PCI后4周升高(P0.05)。對照組與下壁心肌梗死組PCI前、PCI后1周及PCI后4周下壁基底段、下壁中間段、下壁心尖段r EF比較,差異有統(tǒng)計學(xué)意義(P0.05)。下壁心肌梗死組患者PCI前、PCI后1周、PCI后4周及PCI后12周下壁基底段、下壁中間段、下壁心尖段r EF比較,差異有統(tǒng)計學(xué)意義(P0.05);其中PCI后4周及PCI后12周下壁基底段、下壁心尖段r EF較PCI前及PCI后1周升高(P0.05);PCI后12周下壁中間段r EF較PCI前及PCI后1周升高(P0.05)。結(jié)論 RT-3DE可較準(zhǔn)確反映急性心肌梗死患者PCI前后左心室局部收縮功能的變化,可作為評價PCI療效的有效方法。
[Abstract]:Objective to investigate the application of real-time three-dimensional echocardiography (RT-3DE) percutaneous coronary intervention in patients with acute myocardial infarction (PCI) application value before and after the changes of left ventricular regional myocardial function in patients with acute myocardial infarction. Methods from December 2012 to December 2013 in First Affiliated Hospital of Jiamusi University underwent PCI 46 cases as case group, myocardial infarction group was 27 cases. Inferior myocardial infarction group 19 cases; the other and healthy 30 cases as the control group, the control group in the examination, the case group before PCI, respectively RT-3DE 1,4,12 weeks after PCI recording of left ventricular end diastolic volume (R EDV) and the left ventricular contraction end diastolic volume (R ESV), and calculate the segmental ejection fraction (R EF). The control group RT-3DE left ventricular segmentalvolume time curves were ordered, group PCI patients before RT-3DE left ventricular segments 瀹圭Н-鏃墮棿鏇茬嚎鏉備貢鏃犲簭.瀵圭収緇勪笌涓嬪悗澹佸績鑲屾姝葷粍PCI鍓嶅強(qiáng)PCI鍚，
