Figure 4 (A) Kaplan-Meier curves relating short- and long-term outcomes (up to two years) to coronary artery bypass graft surgery (CABG) use during the index hospitalization. (B) Kaplan-Meier estimated mortality rates up to two years by in-hospital CABG, stratified by Thrombolysis In Myocardial Infarction risk score (TRS). Mortality was lower in patients who underwent CABG in the high TRS groups, with a trend toward being lower in the intermediate-risk group, but showed no difference in the low-risk score group.
