Significance of 256 Slice Spiral CT Angiography in Diagnosis of Coronary Artery Disease and Detection of Myocardial Bridge

Abstract

Abstract: This study explored the significance of 256 slice spiral CT angiography (CTA) in the diagnosis of coronary artery disease and the detection of myocardial bridge.172 patients with suspected coronary heart disease were selected, the CTA and coronary angiography (CAG) were performed. The Kappa value of CTA and CAG in the diagnosis of coronary heart disease was 0.801, P<0.05, showed excellent consistency. The Kappa value of CTA and CAG in determining the degree of coronary artery stenosis was 0.817, P<0.05, which showed excellent consistency. The Kappa value of CTA and CAG in the diagnosis of myocardial bridge was 0.758, P<0.05, showed excellent consistency. The thickness of myocardial bridge in patients with myocardial bridge and coronary heart disease was significantly higher than that in patients without coronary heart disease (P<0.05). The area under the ROC curve for predicting myocardial bridge thickness in patients with myocardial bridge and coronary heart disease was 0.900, P<0.05. The 256-layer CTA has a good value in the diagnosis of coronary artery disease and myocardial bridge, and is worthy of clinical use.

Key words: CT angiography, coronary artery, myocardial bridge, diagnostic value
