OBJECTIVE: To evaluate the left ventricular twist characteristics in @entity1 with @entity164 2 @entity6 by using two-dimensional speckle tracking imaging (STI). METHODS: Ninety-three @entity1 with @entity164 2 @entity6 admitted in Zhejiang Hospital from May 2012 to September 2013 were enrolled. According to left ventricular ejection fraction (LVEF), @entity1 were divided into two groups: normal left ventricular systolic function group(group A   LVEF>= 0.50   n=46     and abnormal left ventricular systolic function group   group B, LVEF <0.50   n=47    . Forty-six healthy subjects were selected as normal controls. STI was applied to quantitatively analyze the left ventricular twist. Correlation of the peak of left ventricular twist angle   Peaktw), aortic valve closure time twist angle   AVCtw), and mitral valve opening time twist angle   MVOtw   with LVEF   Tei index   E/A   and E/e was evaluated. Consistency check for STI was conducted to assess its stability and reliability. RESULTS: The Peaktw   AVCtw   and MVOtw in group A were significantly elevated than those in normal controls (P<0.05   . The Peaktw   AVCtw   and MVOtw in group B was lower than those in normal controls and group A    P<0.05   . In @entity6 @entity1   the Peaktw   AVCtw   MVOtw were positively correlated with LVEF    r=0.968   0.966   0.938;P<0.05   and E/A    r=0.798   0.790   0.788; P<0.05      and were negatively correlated with Tei index   r=-0.834   -0.811   -0.797; P<0.05   and E/e   r=-0.823   -0.805   -0.771; P<0.05   . The agreement between measurers and within measurers of Peaktw was satisfactory   between measurers: R=0.957   bias=-0.1   95% consistency limit=-2.8-2.7; within measurer: R=0.964   bias=-0.2   95% consistency limits=-2.7-2.2   . CONCLUSION: STI can be used for early recognition of abnormal changes of cardiac function in @entity164 2 @entity6 @entity1   with high stability and reliability.
