Abstract
We concluded that in patient with STEMI all systolic deformation parameters
Strain (S) , post systolic shortening (PSS) , post systolic index (PSI) , systolic
strain rate (SRS ) ] were impaired .
Mechanical improvement after primary PCI could be predicted by deformation
parameters , mainly systolic strain rate (SRS ) and post systolic index (PSI) and a
cut off value of SRS better than - 0.74 and PSI more than 29 % can be used as
a marker of mechanical improvement in short term follow up .
This study is limited by small number of patients , bad Echogenic window in some
cases was another limitation and short term follow up was also an important
limitation . Even considering these limitations our results are in accordance with
the previous published studies,
Larger studies and longer follow up duration will be necessary to confirm these
data, also using radial and circumferential strain may provide additional
information about functional recovery , finally using different imaging modality -
cardiac MRI- to define reversible regional myocardial mechanics will confirm
these data.
