摘要
对老年、老年前期正常人及陈旧性心肌梗塞（ＯＭＩ）者的核素心室造影（ＲＮＶ），显示年龄不影响左室收缩功能；随年龄增长左室舒张功能减退；ＲＮＶ测定之ＥＦ值与Ｘ线左室造影测定ＥＦ值相关良好。
No significant effect revealed into left ventricular contraction with age factor by RNV among aged and old myocardial infarction patients. The function of left ventricular diastole weakened with age.The EF value is well related between RNA determination and left ventriculography.
