Key result
A review of 22 studies cited by guidelines for preoperative beta-blockers in CABG found that only 2 meta-analyses differentiated timing of administration, and none isolated CABG from other surgeries.
Why the study?
Preoperative beta-blocker administration before isolated CABG is endorsed in quality measures and guidelines to prevent postoperative AF, but recent studies questioned its benefits.
Does β-blocker administration ≤24 hours before isolated CABG prevent postoperative atrial fibrillation and reduce mortality?
Does β-blocker administration ≤24 hours before isolated CABG prevent postoperative atrial fibrillation and reduce mortality?
A review of the evidence supporting guidelines for preoperative beta-blockers in isolated CABG reveals significant gaps in specificity regarding timing and surgery type, challenging the robustness of current quality measures.
Guideline recommendations for preoperative beta-blockers in CABG rest on undifferentiated evidence; leaves open whether CABG-specific, timing-stratified data support current use.

Graca et al. (2018) conducted a review in Isolated Coronary Artery Bypass Graft (CABG) (n=22). Preoperative beta-blockers was evaluated on Applicability to the specifics of beta-blocker administration within 24 hours before surgical incision in isolated CABG patients. A review of 22 studies cited by guidelines for preoperative beta-blockers in CABG found that only 2 meta-analyses differentiated timing of administration, and none isolated CABG from other surgeries.
