Key result
Incomplete revascularization in CABG linked to ~24-fold higher operative mortality.
Why the study?
Factors predictive of operative mortality after aortocoronary bypass grafting for ischemic heart disease were not fully understood.
What clinical, angiographic, and intraoperative factors predict operative mortality in patients undergoing aortocoronary bypass grafting for ischemic heart disease?
Cohort (n=169)
No

Absolute Event Rate: 34% vs 1.4%
p-value: p=<0.01
Incomplete revascularization and severe coronary anatomy (left main or 3-vessel disease) are strongly associated with increased operative mortality during CABG.
No takes yet. Share an insight, caveat, or question.
May support targeting complete revascularization in aortocoronary bypass; leaves open causal confirmation in randomized trials.
Fujiwara et al. (1986) conducted a cohort in Ischemic heart disease (n=169). Incomplete revascularization vs. Complete revascularization was evaluated on Operative mortality (p=<0.01). Incomplete revascularization was associated with a significantly higher operative mortality rate of 34% compared to 1.4% for complete revascularization in patients undergoing aortocoronary bypass.
