高血压病患者心电图 ST-T 改变对冠心病的临床诊断意义

摘要

目的：探讨高血压病患者心电图 ST-T 改变对冠心病的临床诊断意义。方法选取本院收治的112例高血压且伴胸痛的患者，根据 ST-T 变化情况，将其分为 ST-T 动态变化组和 ST-T 无动态变化组。对2组患者均进行心电图监测及冠状动脉造影术，并分析冠状动脉造影术结果与 ST-T 变化的关系。结果 ST-T 动态变化组中冠状动脉阳性者36例（32．1％），阴性者10例（8．9％），而 ST-T 无动态变化组中冠状动脉阳性者18例（16．1％），阴性者48例（42．9％）。ST-T 动态变化组中冠状动脉阳性率明显高于 ST-T 无动态变化组，差异有统计学意义。结论高血压病患者心电图 ST-T 改变与冠心病诊断具有一定相关性，可作为早期诊断冠心病的参考依据之一。%Objective To study the clinical significance of ST-T changes in electrocardio-gram to diagnose coronary heart disease in hypertensive patients.Methods One hundred and twelve patients with hypertension accompanied by chest pain in our hospital were divided into ST-T group with dynamic changes with 46 patients and ST-T group without dynamic changes with 66 patients according to ST-T changes.All patients were given electrocardiogram monitoring and coronary an-giography,and the relationship between the results of coronary angiography and ST-T dynamic changes was analyzed in both groups.Results There were 36 patients (32.1%)of positive coro-nary artery and 10 patients (8.9%)of negative coronary artery in ST-T group with dynamic changes,whereas there were 18 patients (16.1%)of positive coronary artery and 48 patients (42. 9%)of negative coronary artery in ST-T group without dynamic changes.The positive rate of coro-nary artery was evidently higher in ST-T group with dynamic changes than that in ST-T group without dynamic changes,and the difference was statistical significant.Conclusion ST-T dynamic changes in electrocardiogram of hypertensive patients has a certain correlation with the diagnosis of coronary heart disease,which can be considered as one of the references to diagnose the coronary heart disease.
