CABG
Females, compared to males, had greater odds of experiencing 30-day mortality after CABG (OR 1.76, CI 1.47-2.09, p<0.001) (see table 5). Females also experienced increased need for post-operative dialysis (OR 1.31, CI 1.12-1.52, p<0.001), deep sternal wound infections (OR 1.43, CI 1.11-1.83, p=0.005) and length of stay (Beta 1.2, CI 1.0-1.4, p<0.001) compared to males. However, female sex was protective against returning to theatre for post-operative bleeding (OR 0.76, CI 0.65-0.87, p<0.001). There was no sex-related difference in post-operative cerebrovascular accident (CVA) following CABG (OR 1.01, CI 0.79-1.28, p>0.9).
