Research on Ventricular Wall Motion Patients with Coronary Heat Disease by Two-Dimensional Speckle Tracking Echocardiography
摘要
Abstract
Objective To measure minister axial strain, circumferential strain and radial strain of local ventricular muscle by two-dimensional speckle tracking imaging technology,to analyze 2D- STE in the diagnosis of movement abnormal clinical significance of local ventricular muscle. Method This study randomly selected 60 patients with coronary heart disease according to the results of coronary angiography, they are divided into two groups:mild and moderately severe coronary stenosis group, the control group ( 30 cases, coronary stenosis <50%). The myocardial segmental systolic peak strain is measured. Results 1) LS,RS and CS in moderately severe stenosis group were less than those of the control group and mild stenosis group ( P<0 . 01 ) . 2 ) LS mild stenosis group compared with control group,the difference of apex section and the middle section was statistically significant ( P<0 . 01 ) . The difference of anterior wall apex in moderately severe stenosis group was statistically significant comparing with the control group ( P<0 . 05 ) . 3 ) The difference of apex section of CS mild stenosis group was statistically significant comparing with control group ( P<0 . 05 ) . Moderately severe stenosis group compared with control group,the difference of the interval period nowadays,anterior wall after the middle period of the anterior wall and apex section was statistically significant (P<0. 05),the difference of interval before the middle segment and the apex section was statistically significant ( P<0 . 01 ) . 4 ) RS mild stenosis group compared with control group,the difference of the interval before the apex section was statistically significant(P<0. 05),the interval before the middle period and apex section was statistically significant ( P<0 . 01 ) . RS moderately severe stenosis group compared with mild stenosis group, the difference of the anterior wall basal segment was statistically significant (P<0. 05),the difference of interval before the middle period,among the anterior wall and apex section was statistically significant ( P<0 . 01 ) . Conclusion Two-dimensional spot tracking technology can assess myocardial movement function change extent of coronary stenosis.关键词
