Clinical Trial Summary

Bivalirudin is widely used as an anticoagulant to reduce the risk of bleeding in PCI perioperative period. Additionally, 15.7%-32.7% patients have diabetes mellitus who undergo percutaneous coronary interventions (PCI), so bivalirudin was used to anticoagulate in these patients to evaluate its safety and efficacy.


Bivalirudin is a specific reversible thrombin direct inhibitor and the function of thrombin activity site can be recovered through hydrolyzing bivalirudin by thrombin. Therefore, bivalirudin is widely used as an anticoagulant during percutaneous coronary intervention (PCI) for coronary heart disease, and 15.7%-32.7% patients have diabetes mellitus who undergo percutaneous coronary interventions (PCI). At the same time, elderly patients have higher risk of bleeding whose age over 65, so bivalirudin can reduce the risk of bleeding and the incidence of net adverse clinical events for the elderly patients whose age over 65 with diabetes mellitus in PCI perioperative period.

Study Design


Selective PCI
Selective PCI for treatment of elderly patients (age=65) presenting with diabetes mellitus.
Before, during and after surgery, bivalirudin was used according to the dosage regimen to assess it's impact on elderly patients with diabetes mellitus undergoing selective PCI.
