Evaluation effect of three-dimensional speckle tracking imaging on left ventricular systolic function in patients with acute anterior myocardial infarction / 心血管康复医学杂志

ABSTRACT

Objective: To explore evaluation effect of three-dimensional speckle tracking imaging (3D-STI) on left ventricular systolic function in patients with acute anterior myocardial infarction (AAMI).Methods: A total of 40 AAMI patients and 40 healthy subjects were enrolled as AAMI group and healthy control group respectively.Left ventricular longitudinal strain (LS), radial strain (RS), circumferential strain (CS), area of strain (AS), general longitudinal strain (GLS), general radial strain (GRS), general circumferential strain (GCS) and general area of strain (GAS) were measured, compared and analyzed between two groups for 3D-STI technique.Results: Compared with healthy control group, there were significant reductions in left ventricular LS of 12/17 segment, RS and AS of 10/17 segment, and CS of 9/17 segment in AAMI group, P<0.05 or <0.01;for general strain values, compared with healthy control group, there were significant reductions in GLS[(19.59±3.52) vs.(9.25±2.16)], GRS[(36.73±4.83) vs.(25.26±5.19)], GCS[(22.63±4.38) vs.(15.15±3.98)], GAS[(32.87±4.41) vs.(21.73±3.84)]in AAMI group, P<0.01 all.Conclusion: The three-dimensional speckle tracking imaging can accurately detect segmental myocardial strains of left ventricular systolic function in patients with acute anterior myocardial infarction.It can be used as a quantitative measure for clinical evaluation of these patients′ condition.
