Fig 4. Regional longitudinal deformation outside the culprit perfusion region and prognosis.

Univariable and multivariable Cox proportional hazards regression models describing the risk of an adverse outcome for patients stratified into high or low regional longitudinal deformation parameters outside the culprit perfusion region. An abnormal conventional echocardiography is defined by systolic dysfunction determined by an LVEF<45 and/or abnormal diastolic function determined by the presence of diastolic dysfunction grade 1 to 3. Depicting the hazard ratio and the 95% confidence intervals. Also depicting the cut-off values, which are obtained from the mean values, for each regional longitudinal deformation parameter in each myocardial wall. s’ = Peak systolic longitudinal mitral annular velocity determined by color Tissue Doppler Imaging, LD = Mitral annular longitudinal displacement determined by color Tissue Doppler Imaging, SRs = Peak longitudinal systolic strain rate.
