【摘要】:目的探讨应用实时三维超声心动图(RT-3DE)评价急性心肌梗死患者经皮冠状动脉介入治疗(PCI)前后左心室局部功能变化的应用价值。方法选取2012年12月—2013年12月佳木斯大学附属第一医院接受PCI的急性心肌梗死患者46例为病例组,其中下后壁心肌梗死组27例,下壁心肌梗死组19例;另选择同时期体检中心体检健康者30例为对照组,对照组于体检时,病例组于PCI前、PCI后1、4、12周分别做RT-3DE检查,记录左心室各节段舒张末期容积(r EDV)及左心室各节段收缩末期容积(r ESV),并计算出各节段射血分数(r EF)。结果对照组RT-3DE左心室各节段容积-时间曲线规整有序,病例组患者PCI前RT-3DE左心室各节段容积-时间曲线杂乱无序。对照组与下后壁心肌梗死组PCI前及PCI后1周下壁基底段、下壁中间段、下壁心尖段、后壁基底段、后壁中间段r EF比较,差异有统计学意义(P0.05);对照组与下后壁心肌梗死组PCI后4周下壁中间段、后壁中间段r EF比较,差异有统计学意义(P0.05)。下后壁心肌梗死组患者PCI前、PCI后1周、PCI后4周及PCI后12周下壁基底段、下壁中间段、下壁心尖段、后壁基底段、后壁中间段r EF比较,差异有统计学意义(P0.05);其中PCI后1周后壁中间段r EF较PCI前升高(P0.05);PCI后4周及PCI后12周下壁基底段、下壁中间段、下壁心尖段、后壁基底段、后壁中间段r EF较PCI前及PCI后1周升高(P0.05);PCI后12周下壁中间段、后壁中间段r EF较PCI后4周升高(P0.05)。对照组与下壁心肌梗死组PCI前、PCI后1周及PCI后4周下壁基底段、下壁中间段、下壁心尖段r EF比较,差异有统计学意义(P0.05)。下壁心肌梗死组患者PCI前、PCI后1周、PCI后4周及PCI后12周下壁基底段、下壁中间段、下壁心尖段r EF比较,差异有统计学意义(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较PCI前及PCI后1周升高(P0.05);PCI后12周下壁中间段r EF较PCI前及PCI后1周升高(P0.05)。结论 RT-3DE可较准确反映急性心肌梗死患者PCI前后左心室局部收缩功能的变化,可作为评价PCI疗效的有效方法。
[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-鏃堕棿鏇茬嚎鏉備贡鏃犲簭.瀵圭収缁勪笌涓嬪悗澹佸績鑲屾姝荤粍PCI鍓嶅強PCI鍚,
