Abstract:
ObjectiveTo evaluate the value of tissue mitral annular displacement (TMAD) in the assessment of left ventricular long axis systolic function and the relationship of obese degree with left ventricular long axis systolic function in patients with abdominal obesity.MethodsThirty-eight abdominal obesity cases and thirty-four healthy cases were investigated using echocardiography.The images of apical four-chamber view and apical two-chamber view were obtained,systolic mitral annular displacement (MADs),mid-point of mitral annular displacement(MAD-midpt),mid-point of mitral annular normalized displacement(MAND-midpt) and mid-point of mitral annular biplanar normalized displacement(MABNDmidpt) were measured by the technique of TMAD.Their characteristics between patients with abdominal obesity and healthy group were compared,and the relationship of waist-hip ratio(WHR) and related indexes of MAD were analyzed.ResultsIn abdominal obesity group,the MADs at the four site were significantly decreased compared with control group (P＜0.001,respectively),the MAD-midpt and MAND-midpt of apical four-chamber view and apical two-chamber view were significantly decreased compared with control group (P＜0.001,respectively).The WHR related with MABND-midpt independently by the analysis of partial correlation(r=-0.697,P=0.000).ConclusionsThe left ventricular long axis systolic function were damaged in patients with abdominal obesity.The technique of TMAD could quantitatively assess the left ventricular long axis systolic function in patients with abdominal obesity.
