Abstract：Objective To investigate the correlation between the transverse cardiac diameter (TCD) ,cardiothoracic ratio (CTR) and left ventricular (LV) systolic function parameters .Methods A retrospective analysis of 184 subjects suspec‐ted with coronary artery disease ,who underwent chest radiography and dual source computed tomography coronary angi‐ography (DSCT‐CA) ,was performed .The TCD and CTR were derived from chest radiography .The LV systolic function parameters ,such as LV end‐diastolic volume (LVEDV ) ,LV end‐systolic volume (LVESV ) and LV ejection fraction (LVEF) were measured from DSCT‐CA .The relationship of CTR and LV systolic function parameters was analyzed re‐spectively using Pearson correlation .Results The TCD was significantly correlated with LVEDV and LVESV ( r=0 .51 , 0 .33 ,P <0 .0001) ,but with no statistically significant correlation with LVEF .LVEDV was negatively correlated with LVEF ( r =‐0 .48 ,P<0 .0001) .There was no significant relationship between CTR and LV systolic function parameters (LVEDV ,LVESV and LVEF) .Conclusion CTR is not a reliable indicator of LV systolic function and size in patients mostly with preserved LVEF .TCD can be an important parameter to assess LV volume .LV volume is correlated with LV systolic function .
