Abstract:
Objective:To explore the value of different echocardiographic indices on the detection of left ventricular ejection fraction (LVEF) in patients with left ventricular anterior and anterolateral wall motion abnormalities .Methods:Twenty-one patients with left ventricular anterior and anterolateral wall motion abnormalities were enrolled from Jan .2010 to Dec .2015 .The left ventricular ejection fraction (LVEF) of all subjects were measured by M-mode echocardiography ,two-dimensional echocardiography and apical biplane Simpson’s method ,and were compared with left ventricular angiography . Results:There were obvious differences in LVEF evaluation between left ventricular angiography method and M-mode echocardiography or two-dimensional echocardiography (P<0 .05) ,while the correlation between the angiographic method and apical biplane Simpson’s measurement was good .Further the subgroup analysis with the M-mode measurement of 55% as the boundary showed that there were no significant differences among the four kinds of methods when LVEF is more than or equal to 55% .And in patients with LVEF less than or equal to 55% ,LVEF measured by two-dimensional method and M-mode was higher than that of left ventricular angiography (P< 0 .05) ,and there was no statistical difference between Simpson's method and left ventricular angiography (P=0 .061 1) .Conclusions:For patients with left ventricular anterior and anterolateral wall motion abnormalities ,M-mode or two-dimensional echocardiography can be directly adopted when LVEF is more than or equal to 55% measured by M-mode;but if LVEF is less than or equal to 55% ,apical biplane Simpson’s method is recommended for determination .
