摘要:
目的:应用实时三平面组织追踪成像（Triplane-TTI）技术定量评价心肌梗死(MI)患者二尖瓣瓣环及左心室各节段心肌收缩期位移特点。方法： 单纯左前降支MI患者17例（B组），左旋支或（和）右冠支MI患者19例（C组），包含左前降支病变的双支或多支患者23例（D组），健康志愿者25例作为对照组（A组）。采集Triplane-TTI图像，分析获得各室壁房室平面收缩期最大位移（AVPD）及各节段心肌收缩期最大位移（Dmax）。结果： B、C、D 3组平均AVPD与A组比较均减低，D组尤为显著（P<0.05）。B组下侧壁、下壁及后间隔位点，C组前间隔及前壁位点AVPD虽然减低，但与A组比较差异不具有统计学意义。A组同一水平各节段心肌Dmax差异不明显，同一室壁从基底段、中间段至心尖段Dmax逐渐减低，呈梯度变化。B、C、D 3组Dmax不同程度减低，与A组比较及3组间比较大部分心肌节段差异均具有统计学意义（P<0.05）。AVPD 和Dmax减低室壁与梗死相关冠状动脉供血区域基本符合。结论： 对于心肌梗死患者应多位点测量AVPD，避免高估或低估；Dmax能准确反映MI患者左心室局部心肌收缩功能的变化。
Abstract:
AIM:To evaluate the left ventricular long axis systolic displacement in myocardial infarction patients with real-time triplane tissue tracking imaging. METHODS: Fifty-nine patients with myocardial infarction were divided by coronary artery angiography into three groups: group B of 17 patients with single left anterior descending (LAD) coronary artery stenosis, group C of 19 patients with left circumflex coronary artery or/and right coronary artery stenosis and group D of 23 patients with double or triple coronary arteries stenosis with LAD. Twenty-five healthy subjects were selected as group A of normal control group. Systolic atrial ventricular plane displacement (AVPD) and the systolic maximum displacement (Dmax) of left ventricular segmental movement were measured by triplane-TTI. RESULTS: The average AVPD in group B, group C and group D (especially that of group D) decreased significantly compared with that in group A (P<0.05). The AVPD of posterior, inferior and posteroseptal sites in group B and of anteroseptal and anterior sites in group C were not significantly different from those in group A. In group A, the Dmax was the basal segment > the middle segment>the apical segment, with no significant difference in the same level segment. In group B, group C and group D, the Dmax significantly decreased in segments compared with that in group A (all P<0.05). The decrease of AVPD and Dmax was in compliance with the area where infarction coronary blood supplies. CONCLUSION: Evaluation of AVPD in many sites could prevent over- or undervaluation and Dmax could objectively and accurately reflect left ventricular regional systolic functions in patients with myocardial infarction.
