目的 探讨三维超声心动图自动定量（3DEA）技术在评估冠心病患者经皮冠状动脉介入治疗（PCI）术后左室收缩功能中的临床应用价值。
方法 选取武汉协和医院50例行PCI术冠心病患者，分别于术前、术后1月、3月行超声心动图检查，应用二维双平面Simpson’s法(2DBP)及3DEA技术测量左室舒张末期容积（LVEDV）、左室收缩末期容积(LVESV)及左室射血分数（LVEF）。
结果：3DEA测量的LVEDV、LVESV及LVEF与2DBP法测值相关性高；与PCI术前相比， 3DEA技术及2DBP法测量的PCI术后1月、3月LVEDV、LVESV均减低，LVEF均增加，差异均有统计学意义（均P＜0.05）, 与PCI术后1月相比， PCI术后3月3DEA测量的LVEDV、LVESV减低，LVEF增加，差异均具有统计学意义（均P＜0.05），而2DBP测量的LVEDV、LVESV及LVEF差异无统计学意义（均P＞0.05）。与2DBP相比，3DEA技术分析时间短、重复性高。 |

| [Abstract]: Objective To evaluate left ventricular (LV) volumes and ejection fraction in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI) using a 3-dimensional echocardiographic automated algorithm (3DEA). Methods Fifty patients with CHD were enrolled in this study. Left ventricular end-diastolic volume (LVEDV), end-systolic volume (LVESV) and ejection fraction (LVEF) were meseaured before, 1 month and 3 months after PCI by 3DEA and two-dimensional biplane Simpson’s (2DBP) methods. Results LVEDV and LVESV, and LVEF measured by 3DEA significantly correlated with 2DBP measurements. Compared with measurements before PCI, LVEDV and LVESV measured by 3DEA and 2DBP methods were decreased, and LVEF was increased in patients with one month and three months after PCI (P＜0.05). Compared with patients with one month after PCI , LVEDV , LVESV, and LVEF measured by 3DEA further improved in patients with three months after PCI, whereas LVEDV and LVESV, and LVEF measured by 2DBP were not significantly different. The reproducibility of 3DEA was higher than 2DBP. Conclusion 3DEA method is highly reproducible and rapid, and it correlates highly with 2DBP method. Thus it may be a useful technique in serially following patients with CHD and assessing responses to PCI. |
