ConclusionsCoordinated Use of ReoPro and Drug Eluting StentsCoordinated Use of ReoPro and Drug Eluting Stents
1. Reasons for using ReoPro in PCI have not changed.
2. Reasons for using (DE) stents have not changed.
3. These reasons are different.
4. Everything suggests these two therapies are complementary.
5. (As expected), drug-eluting stents have demonstrated dramatic reductions in TVR.
6. (As expected), ReoPro reduces early ischemic events and late mortality.
