Abstract:
Purpose To explore the commonality and disparity between 64-slice CT coronary artery imaging and coronary angiography (CAG) for the diagnosis of coronary heart disease, and to provide evidence for clinical diagnosis.Materials and Methods Forty-nine patients with suspected coronary heart disease (CHD) underwent both 64-slice CT coronary artery imaging and conventional coronary artery angiography, all available coronary segments were evaluated using a 15-segment modified AHA classification, and the results of both methods were compared and analyzed.Results 493 segments of coronary artery were evaluated, results of 29 segments were incongruent between 64-slice CT coronary artery imaging and CAG. With CAG as the gold standard, the sensitivity, specificity, positive predictive value and negative predictive value of CT coronary artery imaging for the diagnosis of coronary artery stenosis were 91.6%, 95.4%, 91.0% and 95.7% respectively.Conclusion There is a high consistency between 64-slice CT coronary artery imaging and CAG for diagnosing CHD, 64-slice CT coronary artery imaging can be used to evaluate the nature of artery plaque, but it is inferior to CAG in diagnosing small angiostenosis.
