Propensity-Matched Sub-Analysis
Propensity matching was performed to create well-balanced cohorts with
respect to baseline variables. This matching resulted in an analysis of
224 patients, 112 (50.0%) with and 112 (50.0%) without GI
complications. In this comparison, rates of reoperation, concurrent
multi-system organ failure, renal failure, and dialysis dependency
remained higher in patients that experienced GI complications. Rates of
stroke, reoperation, cardiac tamponade, and deep sternal wound infection
remained similar (Table 6 ). After propensity matching, 30-day
(69.6% vs 94.6%) one-year (55.4% vs 79.5%), and three-year (52.7%
vs 74.1%) survival remained lower in the GI complication group (all
P≤0.001) (Figure 1B ).
