Abstract
Objective To study the application of speckle tracking imaging(STI) technology in myocardial infarction patients with left ventricular global and local strain. Methods Sixty cases of myocardial infarction patients were selected, and another sixty healthy patients were in control group. Left ventricular apical long-axis positions were recorded in three two-dimensional slices of high frame rate dynamic images. Left ventricular peak systolic strain in paragraph 18(S), the section peak systolic strain(GLS) and left ventricular long axis of the average total strain(GLS-Avg) of all cases were measured by automated functional imaging(AFI). The relationship of GLS-Avg and left ventricular ejection fraction(LVEF) was analyzed. Results Paragraph 18(S) values of left ventricle from the basal to apical segments gradually increased in control group. The intramural difference was not statistically significant(P>0.05), and strain of the wall segment in myocardial infarction group was lower than that of the control group(P<0.05). GLS-Avg correlated well with LVEF(r=0.93, P<0.05). Conclusion Speckle tracking imaging can determine local and global left ventricular myocardial deformation in myocardial infarction patients.
