| 目的 探讨左心室质量指数(LVMI)定量评价经皮冠状动脉介入治疗(PCI)术后患者左心室重构逆转的价值。方法 选择经冠状动脉造影证实为3支冠状动脉病变的冠心病患者30例,于PCI术前2~3天及术后6个月应用实时三维超声心动图测量并比较左心室质量指数(LVMI)、左心室舒张末期容积指数(LVEDVI)及左心室射血分数(LVEF)。结果 与手术前2~3天比较,术后6个月LVMI、LVEDVI减小,差异有统计学意义(P<0.05);LVEF较术前提高,差异有统计学意义(P<0.05);术后6个月,LVMI与LVEF呈负相关(r=-0.80,P<0.05)。结论 PCI能够逆转冠心病患者的左心室重构,LVMI可对其予以定量评价。 |

| Objective To investigate the reverse of the left ventricular remodeling by left ventricular mass index in patients after percutaneous coronary intervention (PCI) with real-time three-dimensional echocardiography (RT-3DE). Methods A total of 30 patients with coronary artery disease were enrolled, in whom coronary angiography revealed 3 branches of coronary artery abnormal. Left ventricular mass index (LVMI), left ventricular end-diastolic volume index (LVEDVI) and left ventricular ejection fraction (LVEF) were measured and compared with RT-3DE 2-3 days before and 6 months after PCI. Results Compared to those before PCI, LVMI and LVEDVI were significantly lower 6 months after PCI (P<0.05), LVEF were significantly higher (P<0.05). Linear correlative analysis showed excellent negative correlation between LVMI and LVEF (r=-0.80, P<0.05). Conclusion PCI can reverse left ventricular remodeling, which can be quantitatively evaluated by left ventricular mass index. |
