Why the study?
Does velocity vector imaging (VVI) accurately assess regional systolic function in patients with post myocardial infarction compared to normal controls and tissue Doppler imaging?
Population
20 patients with post myocardial infarction (PMI) and 15 normal controls (total n=35)
Comparison
Velocity vector imaging (VVI) technique vs Tissue Doppler imaging and normal control segments
Design
Case-control

Supports VVI strain for post-MI regional assessment; leaves open prospective validation before clinical adoption.
Does velocity vector imaging (VVI) accurately assess regional systolic function in patients with post myocardial infarction compared to normal controls and tissue Doppler imaging?
Velocity vector imaging (VVI) is a useful echocardiographic tool for recognizing and quantifying regional systolic function abnormalities in post-myocardial infarction patients.
Chen et al. (2007) studied this question.
