Abstract:
Objective To analyze the correlation between electrocardiogram exercise stress test and coronary artery stenosis degree.Methods A total of 150 patients who performed electrocardiogram exercise stress test were selected,and then coronary angiography were performed within 2 weeks.The sensitivity,specificity,positive predictive value and accuracy of electrocardiogram exercise stress test for diagnosing coronary artery stenosis degree were analyzed.Results Compared with coronary angiography,the sensitivity,specificity,positive predictive value and accuracy of electrocardiogram exercise stress test for diagnosing coronary heart disease were 75％(48/64),74％ (64/86),69％(48/70) and 75％ (112/150),respectively,for diagnosing coronary artery disease were 31％ (19/62),42％ (37/88),27％ (19/70) and 37％ (56/150),respectively.Conclusions Electrocardiogram exercise stress test as a simple,feasible and noninvasive method,has a good concordance with coronary angiography and a high correlation with coronary heart disease,a low correlation with coronary artery disease.It can be used as a good way to screen patients with coronary heart disease.
