Key result
Speckle-tracking imaging detected significant improvements in longitudinal and circumferential strain 3 and 6 months after CABG (P<.05), whereas routine echocardiography parameters remained unchanged.

Speckle-tracking may enhance post-CABG strain detection in preserved LVEF; hypothesis-generating and should not yet change practice.
Cohort (n=145)
Does speckle-tracking imaging detect improvements in myocardial function after CABG surgery more effectively than routine echocardiography in patients with LVEF ≥50%?
p-value: p=< .05
Speckle-tracking imaging is more sensitive than routine echocardiography for detecting early improvements in myocardial function after CABG surgery in patients with preserved LVEF.
Yin et al. (2013) conducted a cohort in Post-coronary artery bypass graft (CABG) surgery (n=145). Speckle-tracking imaging vs. Routine echocardiography was evaluated on Changes in myocardial function (longitudinal and circumferential strain) (p=< .05). Speckle-tracking imaging detected significant improvements in longitudinal and circumferential strain 3 and 6 months after CABG (P<.05), whereas routine echocardiography parameters remained unchanged.
