Clinical Study of Bivalirudin for Percutaneous Coronary Intervention (PCI)
August 16, 2018 updated by: Qian Gong
Safety and Efficacy of Bivalirudin in Patients With Diabetes Mellitus Undergoing Percutaneous Coronary Intervention (PCI)
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.

Detailed Description
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Selective PCI with bivalirudin
Before PCI, bivalirudin is intravenously injected with 0.75 mg/kg, 1.75 mg/(kg.h)
through continuous intravenous drip to finish surgery (no more than 4 hours), if necessary, after the surgery, with a low dose of 0.2 mg/(kg.h)
intravenous drip less than 20 hours.
|
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.
Other Names:
|
Placebo Comparator: Unfractionated heparin
Before PCI, unfractionated heparin sodium is intravenously injected with 70-100 U/kg, and if the operation time exceeded 1h, an additional 1000 U/h would be added.
|
Selective PCI for treatment of elderly patients (age≥65) presenting with diabetes mellitus.

Measure Description |
Time Frame |
---|---|---|
activated clotting time(ACT)
Time Frame: 5min after using drug
|
The ACT test can be used to monitor anticoagulation effects, such as high-dose heparin before, during, and shortly after procedures that require intense anticoagulant administration, such as cardiac bypass, cardiac angioplasty, thrombolysis, extra-corporeal membrane oxygenation (ECMO) and continuous dialysis
