Relationship between the ischemic ST-T changes in ECG and the coronary artery diseases / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To analyze the relationship between the ischemic ST-T changes in electrocardiogram (ECG) and the coronary artery diseases based on the perspective of diagnostics.
@*METHODS@#A total of 341 patients, who underwent coronary angiography in Department of Cardiology of Xiangya Hospital, Central South University from June 2013 to April 2014, were enrolled for this study. The internationally recognized diagnostic criteria for ischemic ST-T changes in ECG and the Judkins diagnostic criteria for coronary angiography were applied, respectively. The sensitivity and specificity of ECG were analyzed.
@*RESULTS@#There were more ischemic ST-T changes in women than that in men (P0.05). For ischemic diagnostic tests by ECG ST-T, the total sensitivity and specificity was 83.6% and 54.4%, respectively. The sensitivity and specificity was 82.3% and 68.0% or 85.0% and 28.2% in the male or female group, respectively. 
@*CONCLUSION@#Ischemic ST-T changes in ECG possess important value in the diagnosis of the coronary artery diseases. The sensitivity of ECG in the diagnosis of myocardial ischemia in women was higher than that in men, whereas the specificity of ECG in the diagnosis of myocardial ischemia in men was higher than that in women.
