[Abstract]:Objective: To evaluate the left ventricular torsion and displacement parameters in patients with Coronary Artery Disease (CAD) by ultrasonic three-dimensional speckle tracking technique, and to explore the correlation between them.
Methods: 120 cases of coronary heart disease diagnosed by coronary angiography from September 2012 to March 2013 were selected, 75 men, 45 women, 36-81 years old, and the average (57.36 soil 12.96) years old. They were divided into left anterior descending group (group LAD, n=47), left circumflex group (group LCX, n=25), right coronary artery group (RCA group, n=23), multiple branch lesions. Group (n=25), left main artery disease was classified into multiple groups. 40 healthy volunteers were selected as normal control group, including 25 male, 15 female, 22~76 years old and average (49.14 soil 12.57) years old. The medical history and physical examination, electrocardiogram, routine echocardiography and other related examinations were used to exclude qualitative heart disease.
The TOSHIBA ARTIDA color Doppler ultrasound diagnostic instrument is used to synchronize the chest lead electrocardiogram. After the patient's calm breathing, the PST-30SBT two-dimensional probe is used to collect the conventional ultrasonic parameters through the chest, and switch to the PST-25SX three-dimensional probe to obtain and store the three-dimensional full volume dynamic image of the left ventricle, and then use the 3D speckle tracking software for the stored image. By off-line analysis, the instrument automatically obtained the left ventricular whole, the basal segment, the middle segment, the peak of the torsional angle of the apical segment (PGT, PBT, PMT, PAT) and the peak time of the corresponding segments (Time-PGT, Time-PBT, Time-PMT, Time-PAT), the left ventricular ejection fraction (LVEF), the left ventricular body and the three dimensional displacement of each segment (three-dimensional displacement, P3DD) and other indicators. The above indexes were compared in each group and the control group, and the correlation between the peak value of left ventricular twist and the displacement parameters and LVEF was analyzed.
Results: 1. comparison of general clinical data: compared with the age, height, weight, heart rate, systolic pressure and diastolic pressure in the two groups, there was no significant difference (P0.05).2. routine echocardiographic parameters: compared with the control group, LVEF decreased in each group of CAD, the difference was statistically significant (P0.05); LAD, LA, LVIDd, LVIDs, LVESV, LVED in group LAD V significantly increased, LVEF decreased, the difference was statistically significant (P0.05 or 0.01).3.CAD and the control group of the left ventricular systolic twist angle peak and peak time: (1) CAD group PGT, PAT decreased, the difference was statistically significant (P0.05 or 0.01); (2) LCX group, RCA group apex, left ventricular systolic twist The trend was in accordance with the normal control group, PBT, PMT had a decreasing trend, but the difference was not statistically significant; Time-PBT was significantly delayed in comparison with the control group (P0.05). Although Time-PMT was delayed in comparison with the control group, there was no significant difference (P0.05); (3) the PBT in the LAD group was lower than the control group (P0.05); PMT was compared with the control group. The difference was not statistically significant (P0.05), and Time-PMT was significantly delayed in comparison with the control group (P0.05). (4) multiple groups of PBT and PMT were significantly lower than those in the control group (P0.01), and the peak time of each segment was lower than that in the control group, and the difference was statistically significant between the.4.CAD group and the control group left ventricular segments. In group CAD, the three-dimensional displacement of the left ventricle decreased significantly (P0.05). Compared with the control group, the anterior wall of the LAD group, the basal and middle segment of the anterior wall, the apical segment of the lateral wall and the apical P3DD decreased significantly (P0.05 or 0.01), and the basal segment and the middle segment of the lower interval of group LCX, the basal segment of the anterior septum, and the basal segment of the anterior septum. In the middle segment, the apical P3DD was significantly reduced, the difference was statistically significant (P0.05 or 0.01). The lower lateral wall and the middle segment of the lower wall of the RCA group decreased significantly (P0.05 or 0.01). The three-dimensional displacement of the systolic peak value of the left ventricular wall in the left ventricular wall decreased significantly by the.5. parameter correlation analysis: CAD group PGT, P AT, PBT are positively related to LVEF, P3DD, PAT and LVEF, P3DD is good (r1=0.53, P10.05; r2=0.44, P20.05).
Conclusion: 3D-STI can be used to study the left ventricular displacement and torsional movement in three dimensional space, so as to detect the left ventricular systolic function of CAD patients sensitive and provide an important clue for the diagnosis of CAD, and it has a broad application prospect.
