Abstract:
Objective To measure various parameters with tissue Doppler imaging, quantitatively score left ventricular wall motion, assess longitudinal wall motion in total and regional myocardium of myocardial infarction patients. Methods Tissue tracking was adopted for assessing left ventricular regional myocardium of 30 myocardial infarction patients (MI group) and 30 normal subjects (control group). After collecting dynamic images and analyzing information off-line, maximum displacement along long axis asynchronously in annular, basal, mid and apical segments of different walls were acquired, and left ventricular wall motion score indexes(TT score indexes) were calculated. Results Maximum displacement in different segments of left ventricular regional myocardium was lower in MI group than control group, especially in infarcted segments. TT score indexes were lower in MI group than control group( 6.23? 1.93 vs 9.71? 1.08, P
