摘要
目的评价老年人动态心电图所见发作性ＳＴ段压低的预后。方法对２７８例进行过动态心电图检查的老年男性患者，按临床情况分为陈旧性心肌梗死（ＯＭＩ）组、心绞痛组、冠心病易患因素组和对照组，并进行１０年以上密切随访，１０年后存活者逐一复查动态心电图。结果１０年前有或无发作ＳＴ段压低，随访中发生冠心病急性事件，除ＯＭＩ组外，余３组差异均有显著性（Ｐ＜００５）；上述４组发作性ＳＴ段压低检出率，１０年前后比较，冠心病易患因素组显著增高（Ｐ＜００５），余３组差异无显著性（Ｐ＞００５）。结论冠心病患者经常出现发作性ＳＴ段压低是疾病严重程度标志之一；老年人发作性ＳＴ段压低，反映存在心肌缺血有较高特异性。
Objective\ To evaluate the prognostic value of acute episodes of ST segment depression in Holter monitoring in elderlies.\ \ Methods\ Two hundred and seventy eight male elderly subjects who had Holter monitoring were divided into 4 groups: groups with old myocardial infarction (OMI), angina pectoris and CHD predisposing factors and a control group. A 10 year follow up was carried out and survivors were rechecked.\ \ Results\ With the exception of OMI group, the occurrence of acute CHD events was significantly different in the other 3 groups ( P <0.05), no matter there was acute episodes of ST segment depression or not ten years ago. In comparing the prevalence of ST segment depression ten years age with that ten years later, significant difference was only found in the group with CHD predisposing factors ( P <0.05), but not in the other 3 groups ( P <0.05).\ \ Conclusions\ It is suggested that the frequency of ST segment depression is an indicator of the severity of CHD. ST segment depression is highly specific for myocardial ischemia in elderly subjects.
