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% and r=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.
