What is the mortality rate of STEMI patients undergoing CABG? 
The mortality rate of STEMI patients undergoing CABG varies depending on the timing. A retrospective study reported an overall in-hospital mortality rate of 5.2% in 440 STEMI patients undergoing CABG as primary reperfusion therapy. Those undergoing CABG 6 hours after symptom onset had a lower in-hospital and long-term (10 years) mortality rate than those undergoing CABG 6 hours after symptom onset. In an analysis of 9476 patients hospitalized with an acute coronary syndrome (ACS) who underwent CABG during the index hospitalization, 1344 (14%) were STEMI patients with shock or intra-aortic balloon placement preoperatively. These individuals had a mortality rate of 4% when CABG was performed on the third hospital day, which was lower than the mortality rates reported when CABG was performed earlier or later during the hospitalization. Studies in which the data from STEMI patients were analyzed separately with regard to the optimal timing of CABG suggest different results.
