Abstract

Abstract:

Objective

To observe the application value of coronary CT angiography (CCTA) combined with dynamic electro-cardiogram(DCG) in diagnosis of coronary heart disease combined with myocardial ischemia.

Methods

A total of 286 patients with suspected coronary heart disease combined with myocardial ischemia were selected. All patients were examined by radionuclide myocardial perfusion imaging (MPI), CCTA and DCG within 2 weeks of admission. The results of MPI, CCTA and DCG were counted, and the results of single and combined diagnosis of CCTA and DCG were compared according to the gold standard of MPI.

Results

In 286 patients, 176 were diagnosed as myocardial ischemia by MPI, 183 by CCTA and 152 by DCG. The diagnostic specificity of CCTA + DCG combined with CCTA was not significantly different from that of CCTA and DCG (P>0.05). The diagnostic sensitivity and accuracy of CCTA combined with DCG were higher than those of CCTA or DCG (P<0.05).

Conclusion

CCTA combined with DCG has high sensitivity and accuracy in the diagnosis of coronary heart disease combined with myocardial ischemia, and has high clinical value.

Key words: Coronary heart disease, Myocardial ischemia, Coronary CT angiography, Dynamic electro-cardiogram
