Meta Analysis Of Coronary CTA And Traditional Invasive Angiography To Diagnose Coronary Artery Disease

Objective： To evaluate the value of64-slice spiral CT diagnostic coronary arterystenosis by using Meta in order to provide a comprehensive information for makingclinical decision.Methods： To screen literature published in January2005to March2011according to the inclusion criteria in the Cochrane Library and OVID, Embase database,Chinese Biomedical Literature Database, Chinese Academic Journal Full-text databases.We conducted quality evaluation and heterogeneity test to the qualified original data.Calculated the sensitivity and specificity, and95%confidence interval, drawn Summaryreceiver operating characteristic (Summary ROC) curves and calculated area under thecurve, and evaluated the coronary CTA of diagnosing coronary artery stenosis.Results：A total of nine studies were consolidated, four domestic literature, foreign literature5. The64-slice spiral CT evaluation of vascular stenosis in a summary of the sensitivity andspecificity, respectively were:0.94(0.93,0.95) and0.96(0.96,0.96) and SROC areaunder the curve was0.9912. Conclusion： Coronary CTA in the diagnosis of coronaryartery disease have a higher sensitivity and specificity and can be usedas a noninvasive method of screening coronary heart disease. The foreign research ofDiagnostic tests designed is more rigorous than domestic research.
