Method Extraction to our hospital treatment of 180 cases of patients with suspected coronary heart disease ( May 2013 to December 2015) as the target, of 180 cases of patients with suspected coronary heart disease are the implementation of the electrocardiogram (ECG) and coronary angiography (CAG), comparison of two kinds of examination results, also on the patients age, body mass index (BMI) were further analysis, analysis of influence of sex, smoking, history of diabetes, hypertension and so on the impact of various factors on severity of coronary artery lesions. Results ECG diagnosis of coronary heart disease sensitivity was 51.85%, specificity was 88.89%, the positive rate was 66.67%; found by coronary angiography in 54 patients with coronary heart disease, there are single lesion in 50 patients,14 cases (28%) patients with ECG ST-T segment changes, 58 cases of patients with multi vessel disease. 32 cases (55.17%) patients with ECG ST-T segment changes, single lesion positive rate was significantly lower than the positive rate of multivessel disease, P lt; 0.05; in the change of ECG ST-T segment cases, there are significant differences of gender, hypertension, blood glucose
