ABSTRACT
Objective:To investigate the Philips 256-slice CT coronary angiography images on a variety of forms of coronary artery calcification and coronary stenosis in relation to predict the value of the study of acute coronary events by coronary angiography and coronary artery calcification score.Methods: From May 2014 to February 2015 in the Third Affiliated Hospital of Qiqihar in patients with suspected coronary artery disease, with256-slice spiral CT coronary artery enhancement scanning and DSA, and using software of automatic analysis for coronary artery calcium score analysis, and comparing the accuracy of the two methods of inspection, combined with the clinical data of patients with scientific prediction of acute coronary events.Results: Different forms of coronary artery calcified plaque resulting in local differences in the proportion of luminal stenosis were statistically significant. AS calcium score standard are in grouped in patients with coronary heart disease (CHD),along with increasing calcium score,the risk of coronary heart disease also increase.Conclusion: The diagnosis of coronary artery calcification score of coronary heart disease have a higher value. Calcium score for judging coronary artery stenosis to have high specific degrees, worthy of clinical popularization and application.
