Objective By comparing the angiographic characteristics of coronary artery in patients with and without diabetes, the diagnostic value of computed tomography coronary angiography(CTCA) in diabetic patients with coronary artery diseases was investigated. Methods Totally 380 diabetes and 481 non-diabetic patients were examined by CTCA. Among them, 111 cases(41 diabetes and 70 non-diabetic patients) were also examined by invasive coronary angiography. The correlation of CTCA with invasive coronary angiography was evaluated.Results There was a good correlationship between the images of CTCA and invasive coronary angiography. There was a significant difference between diabetic and non-diabetic patients in the manifestation of coronary artery disease (45.8% vs 24.5%,P<0.05)and multi-vessel changes(P<0.05). Conclusion Diabetic patients have a high incidence of coronary artery disease. CTCA has a significant diagnostic value in these patients with coronary artery lesion.?更多
