Abstract:
To compare three‐dimensional (3D) and two‐dimensional (2D) speckle tracking echocardiography ( STE ) techniques in the assessment of left ventricular function and myocardial infarct size ( MIS ). Methods Thirty‐two patients diagnosed with ST elevation myocardial infarction and 18 healthy control patients underwent 2D echocardiography, 3D echocardiography, and single photon emission computed tomography ( SPECT ). 3D left ventricular global area strain ( GAS ), 2D and 3D global longitudinal strain ( GLS ), global radial strain ( GRS ) as well as global circumferential strain ( GCS ) were analyzed to correlate with myocardial infarct size detected by SPECT . 2D and 3D left ventricular ejection fraction ( LVEF ) as well as 2D and 3D wall motion score index ( WMSI ) also were measured using conventional echocardiography. Results The 2D‐ GLS values were significantly higher than that of 3D‐ GLS , while 2D‐ GCS and GRS were significantly lower than 3D‐ GCS and GRS , respectively. However, no significant differences in LVEF and WMSI could be observed between 2D and 3D echocardiography. Myocardial strain indices, LVEF , and WMSI using 2D and 3D echocardiography also had good correlations with MIS as measured by SPECT . ROC curve analysis showed that the 3D and 2D myocardial indices, LVEF , and WMSI could distinguish between small and large MIS , while 2D‐ GLS had the highest AUC . Conclusion The 2D and 3D myocardial strain indices correlated well with MIS by SPECT . Among them, the 2D‐ GLS showed the highest diagnostic value, while 3D‐ GRS and GCS had better diagnostic value than 2D‐ GRS and GCS .
