心电图和心血管危险因素诊断冠心病的价值探讨

Electrocardiogram(ECG)and Cardiovascular Risk Factors Diagnostic Value of Coronary Artery Disease

目的探讨冠心病(CHD)患者常规心电图(ECG)及危险因素与冠状动脉造影(CAG)的关系,从而帮助诊断与指导治疗。方法对105例拟诊CHD患者的危险因素及ECG与CAG结果进行回顾性对比分析。结果 105例患者中CAG阳性者78例,ECG有ST-T改变81例,在CAG阳性者中ECG无ST-T改变20例,ECG有ST-T改变58例,危险因素越多CAG阳性率越高。结论临床依据心电图ST-T改变诊断冠心病应慎重,应结合危险因素及CAG等进行系统分析,以提高诊断的准确率。

Objective To study the patients with coronary heart disease（CHD）of conventional electrocardiogram（ECG）and the risk factors and the relationship between coronary artery angiography（the CAG）,to help diagnosis and guiding treatment. Methods 105 cases of clinical risk factors for CHD patients and ECG compared with the CAG results were retrospectively analyzed. Results 105 patients in 78 cases,the CAG positie ECG ST -T change in 81 cases,in the CAG positive ECG without ST -T change in 20 cases,58 cases ECG ST -T change,the more risk factors for the CAG positive rate is higher. Conclusion Clinical basis for ECG ST -T change in thediagnosis of coronary heart disease should be careful,should be combined with risk factors and the CAG and so on carries on the system analysis,in order to improve the diagnostic accuracy.
