Postoperative Survival
Thirty-day (75.2% vs 97.3%), one-year (58.1% vs 93.7%) and
three-year (51.6% vs 88.9%) survival was significantly lower in
patients with GI complications (all P<0.001) (Figure
1A ). Of all significant predictors, experiencing a postoperative GI
complication portended the highest risk-adjusted hazards for mortality
in multivariable modeling (HR 3.12, 95%CI 2.61 to 3.72,
P<0.001). Other risk factors included increasing age, female
gender, diabetes mellitus, dialysis dependency, and preoperative New
York Heart Association Class III or IV symptoms. Urgent or emergent
procedures were associated with increased hazards for mortality, as well
as combined CABG and either aortic or mitral valve replacement
(Table 5 ).
