经静注潘生丁锝－９９ｍ标记的甲氧基异丁基异腈心肌断层显像术筛选后，用核素心室造影术评价非胰岛素依赖型糖尿病（ＮＩＤＤＭ）病人组１８例及对照组１６例在静息及极量运动状况下的心脏收缩功能变化；以多普勒超声心动图评价静息时心脏舒张功能改变。结果：静息状态下ＮＩＤ－ＤＭ组心率虽快于对照组，射血分数（ＥＦ）、峰射血率（ＰＥＲ）与对照组无差异；极量运动时则ＰＥＲ有统计学意义地明显低于对照组，且有４例ＥＦ较运动前降低＞５％，对照组无此现象，此差异接近显著意义（Ｐ＝０．０６５）．静息时ＮＩＤＤＭ组的Ｅ／Ａ比值降低，等容舒张时间延长，揭示ＮＩＤＤＭ病人心室收缩贮备功能降低，舒张功能在静息时已异常。
After intravenous injection of dipyridamole-99m labeled methoxyisobutylisonitrile myocardial infarction, 18 patients with non-insulin dependent diabetes mellitus (NIDDM) group and 16 patients with control group were evaluated by radionuclide venography. And cardiac function under extreme exercise conditions; Doppler echocardiography was used to assess resting cardiac diastolic function changes. Results: The resting heart rate of NID-DM group was faster than that of control group, and the ejection fraction (EF) and peak ejection rate (PER) had no difference with that of control group. PER was statistically significant In the control group, there were 4 cases of EF lower than 5% before exercise, but no significant difference in the control group (P = 0.065). Resting NIDDM group E / A ratio decreased, isovolumic relaxation time, revealing NIDDM patients with reduced ventricular systolic function reserve, diastolic function at rest has been abnormal.
