ABSTRACT
Objective:To investigate the optimal time of coronary computed tomography angiography (CCTA) after taking nitroglycerine,and to provide basis for improving the image quantity of CCTA .Methods:43 patients underwent CCTA were scanned with coronary artery calcium score (CACS)after taking nitroglycerin 0,3,5 and 10 min.Then the diameters of the same coronary artery from the same anatomic location and the expanding rates were measured,and the change regular was analyzed with single factor analysis of variance of SPSS 17.0 software. Results:The average coronary artery expanding rate was 8% 3 min after taking nitroglycerin, and the difference was significant compared with 0 min (P0.05 ).Conclusion:Taking nitroglycerin can significantly expand the diameter of coronary arteries.It is necessary to perform CCTA during 5-1 0 min after taking nitroglycerine.
