Key result
Global longitudinal strain at a cut-off value of -14.65% was a distinct indicator of left ventricular remodeling, which occurred in 48.8% of NSTEMI patients following coronary revascularization.
Why the study?
Conventional echocardiography may not sufficiently explore all complex features of NSTEMI, prompting evaluation of global longitudinal speckle tracking strain to predict LV remodeling following coronary revascularization.
Does global longitudinal speckle-tracking strain predict LV remodeling in patients with moderate risk NSTEMI following coronary revascularization?

Does global longitudinal speckle-tracking strain predict LV remodeling in patients with moderate risk NSTEMI following coronary revascularization?
Global longitudinal strain assessment provides prognostic value for predicting adverse left ventricular remodeling in patients with NSTEMI undergoing revascularization.
Eldamanhory et al. (2023) conducted a cross-sectional in NSTEMI (n=82). Global longitudinal speckle tracking strain was evaluated on LV remodeling (minimum 15% increase in LV end-diastolic volume but no improvement in LV function). Global longitudinal strain at a cut-off value of -14.65% was a distinct indicator of left ventricular remodeling, which occurred in 48.8% of NSTEMI patients following coronary revascularization.
