    Gastrointestinal complications after cardiac surgery occur in 0.4–3% of cases and are linked to high mortality rates of 13–63%.

  • 2

    A retrospective study analyzed 8,544 patients, identifying 162 cases of GI complications through a 1:2 propensity score matching.

  • 3

    Common GI complications included ischemia (50.6%), hemorrhage (31.5%), and obstruction (14.8%), with a mortality rate of 38.8% in the GI group.

  • 4

    Independent predictors of postoperative complications included GI complications, NYHA class >2, and preoperative acute myocardial ischemia.

  • 5

    A risk score was developed incorporating factors like smoking and chronic kidney disease, showing good discrimination and calibration for predicting GI complications.
