Key result
Coronary artery bypass graft surgery significantly improved left ventricular ejection fraction from 49.62% preoperatively to 56.92% at 3 months postoperatively (P≤0.001).
Why the study?
Coronary artery disease is a major cause of death and disability, and the effect of CABG on left ventricular systolic function and regional wall motion abnormalities required evaluation.
Does CABG surgery improve left ventricular systolic function and regional wall motion abnormalities in patients with coronary artery disease?

May support short-term LV recovery after CABG; hypothesis-generating and requires RCT confirmation before practice change.

Absolute Event Rate: 56.92% vs 49.62%
p-value: p=≤0.001
CABG surgery significantly improves left ventricular ejection fraction and regional wall motion abnormalities at 3 months post-operation.
Ismael et al. (2019) conducted an observational in Coronary artery disease (n=50). Coronary artery bypass graft (CABG) surgery vs. Pre-operative baseline was evaluated on Left ventricular ejection fraction (LVEF) at 3 months (p=≤0.001). Coronary artery bypass graft surgery significantly improved left ventricular ejection fraction from 49.62% preoperatively to 56.92% at 3 months postoperatively (P≤0.001).
