The study aims to evaluate the diagnostic accuracy of echocardiographic resting strain imaging compared to SPECT for identifying myocardial viability in post-MI patients with LV systolic dysfunction.

May support resting strain for post-MI viability assessment; hypothesis-generating and requires prospective validation before practice change.
Left ventricular systolic dysfunction following myocardial infarction increases risks of heart failure and sudden death. Identification of viable myocardium is important before revascularisation techniques. Therefore, in this study, we sought to explore the accuracy of resting strain to predict myocardial viability. Aim-Myocardial deformation imaging based on strain analysis could differentiate between viable and non-viable myocardial tissue. The differentiation of viable from non-viable myocardium is therefore highly relevant in patients who are being considered for revascularisation.
