Abstract:Objective To explore the relationship between total ischemia burden(TIB) by ambulatory electrocardiography and coronary CT angiography(CTA) examination.MethodsOne hundred and four patients with symptoms of chest pain or risk factors for coronary heart disease underwent TIB and coronary CTA examination. The positive rates of TIB between coronary CTA positive group and negative group were compared and Spearman correlation test was carried out between the number of coronary lesions and TIB value. ResultsCompared with coronary CTA negative group, the positive rate of TIB in positive group was significantly increased(P<0.01) while the correlation coefficient between the number of coronary lesions and TIB value was 0.532(P<0.01) indicating a positive correlation.ConclusionThere is a significant correlation between TBI and coronary CTA examination. They reflect coronary heart disease in aspects of quantification of myocardial ischemia and degree of stenosis in coronary anatomy respectively and the combination of them are clinically valuable.
