Abstract
Objective This paper compared the Results between cardiac MSCT and echocardiography, to evaluate the left ventricular function using coronary CT angiography (CTA).Methods 43 patients [16 men, 27 women, range from 44~87, mean age (62.2±8.7)] were collected in this study. All patients underwent cardiac MSCT, echocardiography (EC) was taken within 48 h. The data were transferred to the postprocessor workstation, and left ventricular ejection fraction (EF) and left ventricular fractional shortening (FS) were given automatically by cardiovascular software. The difference of EF and FS measured by the two Methods were compared. The correlation and concordance of Results between MSCT and echocardiography were also assessed.Results The Results of EF and FS for CTA and EC were (64.05±5.74)%, (60.81±4.6)% and (26.42±3.68)%, (31.16±3.66)%, respectively. There was a significant statistically difference in the EF and FS between the two Methods (t=6.94,P=0.000;t=-16.5,P=0.000). However, the EF and FS measured by CTA have better correlation and consistency with those measured by EC (r=0.85,P=0.000, bias 3.05% andr=0.87,P=0.000, bias 1.89%).Conclusion Application of coronary CTA is quick and convenient to measure the left ventricular function, and the measurement Results with EC has better correlation and consistency.关键词
