摘要
应用γ-心功能仪对22例陈旧性心肌梗塞患者(OMI)的左心舒张功能进行了测定。前壁心肌梗塞(Ant-MI)患者左心射血分数(LVEF)和高峰充盈率(PFR)均都明显降低(P<0.01)。而下壁心肌梗塞的患者 LVEF 与正常人无差异,但 PFR 与正常人差异明显(P<0.05)。结果表明,OMI 的 PFR 与 LVEF 存在明显的相关(R=0.81)。PFR 在 OMI 患者中的异常发生率是88%。心肌梗塞发生的部位不同对心功能的影响是不同的。PFR 如果正常,可以认为左心功能是正常的,而正常的左心收缩功能,则未必其舒张功能正常。因此,PFR 在探查 OMI 患者时比 LVEF 敏感。
Left ventricular diastolic function in 29 patients with old myocardial infarction(OMI)was determined using nuclear stethoscope.The results indicated that the left ventricular ejection fraction(LVEF)and peakfilling rate(PFR)were significantly reduced in patients with anterior infarction(Ant-MI)as compared with the control group.However,no significant differenceswere observed between the group of patients with inferior MI(Inf-MI)and controlgroup.PFR in Patients Inf-MI was clearly reduced.The results showed that normal PFR always indicated normal left ventricularfunction,but normal left ventricular systolic function was not necessarily indicativeof normal diastolic function.PFR correlated well with LVEF in OMI(γ=0.81).Abnormal PFR at rest was found in 88% patients with OMI.Therefore,PFR is moresensitive than LVEF in the detection of OMI.Myocardial infarction occurred in di-fferent regions.
