Key result
In patients undergoing emergency CABG after failed PTCA, using an internal mammary artery graft yielded an overall mortality of 13% compared to 9% with venous grafts only (p=0.58).
Why the study?
Does the use of the internal mammary artery as a graft influence operative and mid-term mortality in emergency CABG after failed PTCA compared to venous grafts only?

IMA use in emergency CABG after failed PTCA was not associated with higher mortality; leaves open whether it improves mid-term outcomes in this setting.
Cohort (n=56)
Yes

Absolute Event Rate: 13% vs 9%
p-value: p=0.58
The use of the internal mammary artery in emergency CABG after failed PTCA does not significantly increase mid-term mortality compared to venous grafts, despite longer operative times.
Nollert et al. (1995) conducted a cohort in Emergency CABG after failed PTCA (n=56). Internal mammary artery (IMA) graft vs. Venous grafts only was evaluated on Overall mortality (p=0.58). In patients undergoing emergency CABG after failed PTCA, using an internal mammary artery graft yielded an overall mortality of 13% compared to 9% with venous grafts only (p=0.58).
