Title: Evaluation of the Global and Regional Left Ventricle Function with Dual-source CT in Patients with Coronary Artery Disease:Compared with Routine Echocardiogram
Abstract: Objective To evaluate the agreement between DSCT and ECG to assess the global and regional left ventricle function in patients with coronary artery disease.Materials and Methods 25 cases of coronary disease underwent DSCT coronary angiography,and the data were used to assess the ejection fraction(EF)and fractional shortening(FS),and regional wall motion compared with ECG.Results There was no significant difference between DSCT and ECG to evaluate the EF and FS(P0.05),the correlation was also good(r=0.86 and 0.87,P0.001,respectively).The agreement between DSCT and ECG in diagnosing regional wall motion abnormality was good,no matter counted as cases(Kappa=0.85,P0.001) or segments(Kappa=0.87,P0.001).The wall thickening fraction of the segments with abnormal motion diagnosed by DSCT were significant lower than that of its opposite segments [(20.55±24.10)% vs(78.63±30.98)%,P0.01].Conclusion With the breakthrough of the temporal resolution,DSCT permits accurate assessing left ventricle function even in patients with heart rate variability,and agreement with routine ECG is good.DSCT can provide more information for CAD diagnosis and prognosis.
