摘要 目的应用单心动周期实时三维超声心动图(single-beat real-time three-dimensional echocardiography,s RT-3DE)评价冠心病(CHD)患者血管狭窄程度对左、右心功能的影响。方法 50例经皮冠状动脉造影术(PCA)证实单支右冠状动脉病变并且近段>50%狭窄或闭塞的CHD患者,分为50%<狭窄≤70%组和狭窄>70%组两个实验组,行s RT-3DE检查,与对照组比较,分析狭窄血管对心功能的影响,以及支配相关区域EF及平均充盈率(MFR)。结果 (1)50%<狭窄≤70%组、狭窄>70%组和对照组比较,LV-EF、及LV-MFR均有统计学意义(P<0.01),狭窄程度越重,LV-EF及LV-MFR越低。(2)50%<狭窄≤70%组、狭窄>70%组和对照组比较,RV-EF及RV-MFR差异均有统计学意义,狭窄程度越重,RV-EF及RV-MFR越低。(3)50%<狭窄≤70%组、狭窄>70%组和对照组比较,狭窄程度越重,血管病变所支配左室壁相对应节段的EF及MFR越低。结论单心动周期实时三维超声心动图能够很好评价冠心病患者左、右心功能。
