Key result
Global longitudinal peak systolic strain by speckle tracking echocardiography significantly correlated with myocardial infarction size (r=0.39, p=0.03) and ejection fraction (r=0.35, p=0.01) in STEMI.
Why the study?
Does global longitudinal peak systolic strain (GLPSS) by speckle tracking echocardiography correlate with infarction size and ejection fraction in patients with STEMI after primary PCI?
Population

GLPSS may estimate large infarct size post-STEMI PCI; leaves open incremental prognostic value over LVEF.
Observational (n=30)
Does global longitudinal peak systolic strain (GLPSS) by speckle tracking echocardiography correlate with infarction size and ejection fraction in patients with STEMI after primary PCI?
Effect estimate: r = 0.39
p-value: p=0.03
Global longitudinal strain by speckle tracking echocardiography is an effective and inexpensive tool that correlates well with myocardial infarction size and ejection fraction in STEMI patients post-PCI.
Ismail et al. (2015) conducted an observational in STEMI (n=30). Global longitudinal peak systolic strain (GLPSS) by speckle tracking echocardiography was evaluated on Correlation between LV GLPSS and infarction size (r = 0.39, p=0.03). Global longitudinal peak systolic strain by speckle tracking echocardiography significantly correlated with myocardial infarction size (r=0.39, p=0.03) and ejection fraction (r=0.35, p=0.01) in STEMI.
