Figure 1 Ischemic Events at 30 Days and 1 Year in Patients With and Without GIB
Patients with versus without gastrointestinal bleeding (GIB) have significantly increased 30-day (A) and 1-year (B) rates of cardiac and all-cause mortality, myocardial infarction, and composite ischemic outcome.

Figure 2 Cumulative Risk of All-Cause and Cardiac Death in Patients With and Without GIB
By Kaplan-Meier estimates, patients with versus without gastrointestinal bleeding (GIB) had significantly higher all-cause (A) and cardiac (B) death at 1 year.

Figure 3 Multivariable Predictors of 1-Year Individual and Composite Ischemic End Point
Gastrointestinal bleeding was an independent predictor of 1-year all-cause mortality, cardiac mortality, myocardial infarction, and the composite ischemic end point. CABG = coronary artery bypass grafting; CI = confidence interval; HR = hazard ratio; MI = myocardial infarction; PCI = percutaneous coronary intervention.
