摘要 目的:探讨空腹血糖受损患者左室舒张功能失调(left ventricular diastolic dysfunction,LVDD)对其运动耐力的影响。方法:应用超声心动图探测IFG患者早期左室舒张功能的改变,借助踏车运动试验观察空腹血糖受损(IFG)患者LVDD对其运动量的影响。结果:IFG伴LVDD患者,与舒张功能正常者比较,其运动时间明显减少,为9.3±2.2:13.5±1.7分钟,P<0.05),METs明显下降(10.4±1.9:12.4±1.1,P<0.05)。相关分析显示:A/E比值与运动时间及METs呈负相关(r=-0.648,P<0.01;r=-0.664,P<0.01),Ai/Ei也与运动时间及METs呈负相关(r=-0.568,P<0.01;r=0.582,P<0.01)。结论:IFG伴LVDD患者的运动耐力明显降低,且LVDD程度与运动耐力呈负相关。
