cohort complications; in- Patients who underwent CABG within
2-3 hospital mortality 24 h were more likely to develop any
complications compared to those in 2-
4-7 3 and 4-7 days groups, respectively
(OR = 1.22, 95% CI 1.05-1.41, and OR
= 1.18, 95% CI 1.01-1.36, respectively).
Differences in complications between
2-3 and 4-7 days groups were not
statistically significant (OR = 0.97,
95% CI 0.85-1.11)

Odds of in-hospital mortality was
higher in the < 1 day, compared to 2-3
days group (OR = 1.85, 95% CI 1.52-
2.25) and 4-7 days group (OR = 2.21,
95% CI 1.82-2.68). The latter two
groups did not differ in terms of in-
hospital mortality

CABG timing did not affect the in-
hospital mortality of patients with
unstable angina or those with NSTEMI
