Stenting has dramatically increased the safety of PCI. Data from 23,087 patients who had PCI at Mayo Clinic from 1979 till 2003 was analyzed and it was found that though there has been an increase in high-risk patients undergoing PCI, a decrease in incidence of patients requiring emergency CABG in the current stent era (2000-2003, n= 6,577) is also noteworthy.

Overview

Stenting has dramatically increased the safety of PCI. Data from 23,087 Mayo Clinic patients who had a PCI from 1979 to 2003 was analyzed, and it was found that though there has been an increase in high-risk patients undergoing PCI, there has been a decrease in the incidence of patients requiring emergency CABG in the current stent era (2000-2003, n= 6,577). The in-patient mortality rate for those requiring emergency CABG remains unchanged.[1]
