Abstract 【Objective】Catheter coronary angiography was set as the "gold standard" to investigate the value of multi-slice spiral CT coronary calcification score and dynamic electrocardiogram (ECG) monitoring in the early diagnosis of coronary artery disease.【Methods】A total of 55 cases of patients with coronary heart disease in our hospital from April 2013 to January 2014 were collected for the study. All patients underwent CT angiography (CTA, for multi-slice spiral CT coronary calcification score) and dynamic ECG detection. The results were compared with those of CAG "gold standard". The sensitivity and specificity of the two different diagnostic methods were analyzed.【Results】The sensitivity of dynamic ECG monitoring was 97.06% (33/34); the specificity was 90.48% (19/21), and the positive predictive value was 94.29% (33/35). The sensitivity of multi-slice spiral CT coronary angiography was 100% (32/32); the specificity was 86.96% (20/23), and the positive predictive value was 91.43% (32/35). There were no statistical differences between the two groups (P＜0.05).【Conclusion】Both dynamic electrocardiogram and multi-slice spiral CT coronary calcification score are highly accurate for early diagnosis of coronary heart disease. Dynamic ECG monitoring, however, is more practical in clinical settings due to its simplicity, repeatability, and non-invasive nature.
