TI  - Segment-orientated analysis of two-dimensional strain and strain rate as assessed
      by velocity vector imaging in patients with acute myocardial infarction.
PG  - 106-13
AB  - AIMS: Strain rate imaging techniques have been proposed for the detection of
      ischemic or viable myocardium in coronary artery disease, which is still a
      challenge in clinical cardiology. This retrospective comparative study analyzed
      regional left ventricular function and scaring with two-dimensional strain (2DS) 
      in the first 4 to 10 days after acute anterior myocardial infarction (AMI).
      METHODS AND RESULTS: The study population consisted of 32 AMI patients with an
      LAD occlusion and successful reperfusion. The assessment of peak systolic 2DS and
      peak systolic strain rate (SR) was performed segment-oriented with the
      angle-independent speckle tracking algorithm Velocity Vector Imaging (VVI). The
      infarcted, adjacent and non-infarcted segments were revealed by late enhancement 
      MRI (LE-MRI), which was used as reference for the comparison with 2DS. The
      infarcted segments showed a significant decrease of tissue velocities, 2DS and SR
      in comparison to the non-affected segments. CONCLUSION: 2DS and SR as assessed by
      VVI seem to be a suitable approach for echocardiographic quantification of global
      and regional myocardial function as well as a promising tool for multimodal risk 
      stratification after anterior AMI.
