ABSTRACT
Objective:
To discuss the application value with two-dimensional ultrasound speckle tracking technique in the evaluation of left ventricular function in patients with OSAS.Methods:
Selected 110 cases of hospital patients with OSAS in recent years, used STI technical analysis of left ventricular myocardium using different directions overall resilience, Left ventricular torsion and systolic mitral annular midpoint of the maximum displacement (MAD) and left ventricular ejection fraction (LVEF) relationship, performed using SPSS 17.0 statistical correlation analysis.Results:
MAD had a significant correlation with LVEF(r=0.81, P<0.01); GLS(r=-0.74, P<0.01),GRS GRS(r=0.57, P<0.01),GCS (r=-0.55, P<0.01) and LVtw(r=0.65, P<0.01)were significantly associated with LVEF;MAD and GLs(r=-0.69, P<0.01),GRs (r=0.49, P<0.01), LVtw (r=0.45, P<0.01)were significantly associated;MAD and GCs (r=-0.39, P<0.05)with a negative correlation.Conclusion:
STI resilience through the myocardium, ventricular torsion and systolic mitral annular maximum displacement at the midpoint of the analysis, can accurately evaluate left ventricular longitudinal, radial and torsional motion synchronization, highly correlated with left ventricular ejection fraction, good consistency, with a very broad application prospects.
