- Abstract: Objective To explore the methods and roles of electrocardiogram (ECG) and multi-slice spiral CT coronary angiography (MSCTCA) in the diagnosis of coronary heart disease (CHD) by comparing and analyzing ECG ST-segment changes and MSCTCA, thereby providing more effective information for the clinical diagnosis of CHD. Methods A total of 64 patients with suspected or confirmed CHD by clinical diagnosis underwent ECG and MSCTCA. The examination consistency between two methods was compared, and the positive rates of two methods in the examination of lesions of different parts, different degrees and different types were also compared. Results Compared with MMSCCA, ECG ST-segment changes had a sensitivity, specificity and overall coincidence rate of 56.82%, 50% and 54.69%, respectively. The test consistency between two methods was poor (Kappa=0.061, P<0.05). The positive rate of MSCTCA in patients with positive I/avL/V1-5 lead ST-segment changes and those with positive II/III/avF lead ST-segment changes was significantly higher (P<0.05), while the positive rate of ECG ST-segment changes in patients with severe and mild coronary artery stenosis was significantly increased (P<0.05). The positive rate of ECG ST-segment changes in patients with moderate coronary stenosis was similar to that in patients with mild coronary stenosis (P>0.05), but the positive rate of ECG-ST segment changes in patients with multiple-vessel coronary artery lesions was significantly higher than that in patients with single-vessel coronary artery lesions (P<0.05). Conclusion The consistency between ECG and MSCTCA is poor. In clinic, it is not appropriate to adopt ECG or MSCTCA alone. ECG ST segment changes have higher detection rates in patients with severe coronary artery stenosis and those with multiple-vessel coronary artery lesions, while MMSCCA has higher detection rates in patients with postitive I/avL/V1-5 lead ST-segment changes and those with positive II/III/avF leads ST-segment changes.
