Efficacy and Safety of Different Dose of Tirofiban in Interventional Treatment of Complex Coronary Artery Disease

Phase 4
Conditions
Coronary Artery Disease
Interventions
Registration Number
NCT02294994
Lead Sponsor
Second Hospital of Jilin University
Brief Summary

The aim of the study is to investigate the efficacy and safety different dose of GPIIb/IIIa inhibitor (tirofiban) in interventional treatment of complex coronary artery disease ,which include bifurcation lesion, left main lesion, multiple vessel disease, intracoronary thrombus, SYNTAX score\>26,chronic total occlusion disease. The primary endpoint is all-cause mortality. Secondary endpoints are incidence of major bleeding and the rate of site access complication.

GroupInterventionDescription
half dose tirofibantirofibanTirofiban was administered once the wire had crossed the lesion during PCI with a bolus dose of 25 µg/kg of bodyweight, followed by an infusion of 0.075 µg per kilogram per minute for 24 to 36 hours.UFH heparin was administered as a bolus of 100 U/kg before PCI.
recommended-dose TirofibantirofibanTirofiban was administered once the wire had crossed the lesion during PCI with a bolus dose of 25 µg/kg of bodyweight, followed by an infusion of 0.15 µg per kilogram per minute for 18 to 24 hours. UFH heparin was administered as a bolus of 100 U/kg before PCI.
none tirofibantirofibanTirofiban was not administered ,UFH heparin was administered as a bolus of 100 U/kg before PCI.
