Which can predict left ventricular size and systolic function: Cardiothoracic ratio or transverse cardiac diameter

Which can predict left ventricular size and systolic function: Cardiothoracic ratio or transverse... PURPOSE: The aim of this study is to investigate the associationbetween the cardiothoracic ratio (CTR), transverse cardiac diameter(TCD), and left ventricular (LV) size and systolic function in patients withor without preserved LV ejection fraction (LVEF).METHODS: A total of 181 subjects suspected with coronary arterydisease underwent chest radiography (CR) and dual source computed tomographycoronary angiography (DSCT-CA). TCD and CTR were derived from CR. The LVsize and systolic function parameters, such as LV end-diastolic volume(LVEDV), LV end-systolic volume (LVESV) and LVEF were measured from DSCT-CA.The association between TCD, CTR and LV size and systolic functionparameters were analyzed according to LVEF value (< 55%, depressed LVEFgroup; versus ≥ 55%, preserved LVEF group).RESULTS: Both TCD and CTR were higher in the depressed LVEF groupcompared with the preserved LVEF group. Significant correlations were foundbetween TCD, CTR and LVEDV, LVESV, LVEF in depressed LVEF group. However,there was no significant association detected between CTR and LV size andsystolic function parameters in preserved LVEF group. Both the LVEDV andLVESV showed a positive correlation with TCD in preserved LVEFgroup.CONCLUTION: Although CTR was not a reliable indicator ofLV size and systolic function in patients with preserved LVEF, it wascorrelated with LV size and LVEF in depressed LVEF patients. Furthermore,TCD showed stronger correlations with LV size and systolic function even inpatients with preserved LVEF. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of X-Ray Science and Technology IOS Press

TCD and CTR were derived from CR. The LVsize and systolic function parameters, such as LV end-diastolic volume(LVEDV), LV end-systolic volume (LVESV) and LVEF were measured from DSCT-CA.The association between TCD, CTR and LV size and systolic functionparameters were analyzed according to LVEF value (< 55%, depressed LVEFgroup; versus ≥ 55%, preserved LVEF group).RESULTS: Both TCD and CTR were higher in the depressed LVEF groupcompared with the preserved LVEF group.
