| 摘 要： | 目的探讨定量组织速度成像(QTVI)技术评价2型糖尿病左室舒张功能的临床价值.方法应用QTVI技术获取86例健康志愿者(NOR),77例糖尿病患者(DM)左室各室壁的房室瓣环、基底段、中段和心尖段的心肌组织运动曲线,测量其收缩期速度(Vs),舒张早期充盈速度(Ve),以及左房收缩期速度(Va),并将各室壁侧房室瓣环的收缩期和舒张期测值和Ve/Va比值平均.比较两组间二尖瓣环水平各个参数的差异性.以二尖瓣环Ve/Va<1,以二尖瓣口舒张期血流频谱E/A<1分别作为评判左室舒张功能异常的标准,比较两种方法对DM组左室舒张功能异常的检出率.根据空腹血糖(FPG)及糖化血红蛋白水平(HbA1C%)将糖尿病组进一步分为DM1组(n=35),DM2组 (n=42),比较两组间Ve/Va<1的室壁节段数.结果①糖尿病组二尖瓣环Ve/Va比值明显低于正常组(P<0.001).②QTVI法和多普勒血流频谱法对DM组左室舒张功能异常的检出率差异有显著性(P<0.001),而在正常组两种方法无显著性差异(P>0.05).③在DM1组中的Ve/Va<1的节段数明显少于DM2组(P<0.001).结论 QTVI能够准确定量评价糖尿病的左室舒张功能,并能敏感反映血糖水平对左室舒张功能的损害,为临床选择合理的治疗措施及对疗效的评判提供了定量指标.
