Key result
Dual-source computed tomography correlated well with echocardiography for assessing left ventricular ejection fraction (r=0.70), end-systolic volume (r=0.87), stroke volume (r=0.83), and EDV (r=0.90).

Dual-source computed tomography provides an accurate and practical method for assessing left ventricular function, correlating well with echocardiography in patients with coronary heart disease.
We aimed to assess parameters reflecting left ventricular function by dual-source computed tomography (DSCT) with echocardiography (ECG) as control. Fifty-eight patients with coronary heart disease (CHD) were recruited from January to June 2011; 29 CHD patients had type II diabetes. All patients were assessed by cardiac DSCT and ECG examination. DSCT and ECG correlated well for ejection fraction (EF) (r = 0.70), end-systolic volume (ESV) (r = 0.87), stroke volume (SV) (r = 0.83), and end-diastolic volume (EDV) (r = 0.90). The mean ESV and EDV values measured by the two methods in CHD patients with type II diabetes were higher than those in non-diabetic patients, whereas the mean EF was lower. DSCT is an accurate and practical method for assessing left ventricular function.

Shen et al. (2014) conducted a cross-sectional in Coronary heart disease (n=58). Dual-source computed tomography (DSCT) vs. Echocardiography (ECG) was evaluated on Left ventricular function parameters (EF, ESV, SV, EDV) (r = 0.70 to 0.90). Dual-source computed tomography correlated well with echocardiography for assessing left ventricular ejection fraction (r=0.70), end-systolic volume (r=0.87), stroke volume (r=0.83), and EDV (r=0.90).
