Abstract：Objective To evaluate the left ventricular diastolic function in coronary heart disease (CHD)
patients without regional wall motion abnormality by three dimensional SI-DI (Strain Imaging Diastolic
Index) so as to investigate the effectiveness of application of three dimensional SI-DI in detecting CHD.
Methods According to CAG (Coronary Angiography), 113 patients without regional wall motion
abnormality were divided into three groups: None-CHD Group (n=35), Single-Branch Disease Group
(n=37, single coronary stenosis≥50%), Multiple-Branch Disease Group (n=41, two or more than two
coronary stenosis≥50%). Transthoracic acquisition of full-volume real-time three-dimensional images
and conventional two-dimensional images were made to obtain two-dimensional and three-dimensional
routine parameters, area, longitudinal, radial and circumferential end systolic strain and corresponding
strain of 1/3 of pre-diastolic period. According to the formula calculation of area SI-DI (A-SI-DI),
longitudinal SI-DI (L-SI-DI), radial SI-DI (R-SI-DI), circumferential SI-DI (C-SI-DI) was made. The
effectiveness of each parameter in diagnosis of patients with coronary heart disease was analyzed.
Results There were no significant difference between the routine parameters of three groups (P＞0.05).
The longitudinal and area SI-DI in Single-Branch Disease Group were lower than these of None-CHD
Group (P<0.05). The area, longitudinal, radial and circumferential SI-DI in Multiple-Branch Disease
Group were lower than these of None-CHD Group (P<0.05); while, area, longitudinal and radial SI-DI
in Multiple-Branch Disease Group were lower than these in Single-Branch Disease Group (P<0.05). The
area, longitudinal, radial and circumferential SI-DI were significantly correlated with Gensini score, r=(-
0.689, -0.844, -0.510, -0.476) in None-CHD group, r=(-0.794, -0.768, -0.702, -0.589) in Single-Branch
Disease Group, r=(0.806, -0.837, -0.714, -0.617) in Multiple-Branch Disease Group. Conclusion Threedimensional
SI-DI could quantitatively assess the left ventricular diastolic function and demonstrate itseffectiveness in early detection and diagnosis of coronary heart disease.
