To explore the value of multi-detector computed tomography angiography in evaluation of coronary artery elasticity by measuring and calculating coronary artery elastic parameters. 

Multi-detector computed tomography angiography was performed in 86 patient s from September 2012 to October 2013. Diameter changes of 344 segment of coronary artery in the systolic and diastolic phases were measured by CT coronary angiography. Correlations between coronary artery elastic parameters and pulse pressure and mean arterial pressure were analyzed ,and correlations between coronary artery compliance and systolic blood pressure were analyzed ,including the left mainartery ,left anterior descending artery ,left circumflex artery and right coronary artery.

Coronary artery compliances in the various branches were different and P=0.001( P<0.05) in the Friedman Test ,coronary artery compliances and pulse pressure and mean arterial pressure were negatively correlated.Coronary artery compliances and systolic blood pressure were negatively correlated ( P<0.05). The remaining coronary artery elastic parameters and pulse pressure and mean arterial blood pressure were less relevant.

Multi-detector computed tomography angiography can be used as an effective means of measuring coronary lumen.Coronary artery compliance can reflect the elasticity of normal coronary vessel walls.

Multi-detector computed tomography angiography can be used as an effective means of measuring elasticity of normal coronary vessel walls.
