MedicalResearch.com Interview with: Deepak L. Bhatt, MD, MPH, FACC, FAHA, FSCAI, FESC Executive Director of Interventional Cardiovascular Programs, Brigham and Women’s Hospital Heart & Vascular Center Professor of Medicine, Harvard Medical School Boston, MA 02115 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Cangrelor is a potent, fast on, fast off, intravenous ADP receptor antagonist that is now available for use during PCI. Glycoprotein IIb/IIIa inhibitors are intravenous antiplatelet agents that work by a different mechanism. Doctors have asked whether there is any advantage to combining them or whether one class is preferable to the other during PCI. We analyzed close to 25,000 patients from the CHAMPION trials. Cangrelor’s efficacy in reducing peri-procedural ischemic complications in patients undergoing PCI was present irrespective of glycoprotein IIb/IIIa inhibitor administration. However, glycoprotein IIb/IIIa inhibitor use resulted in substantially higher bleeding rates, regardless of whether the patient was randomized to cangrelor or to clopidogrel. Thus, in general, cangrelor and glycoprotein IIb/IIIa inhibitors should not routinely be combined. If an operator wishes to use a potent intravenous antiplatelet during PCI, cangrelor is similarly efficacious as glycoprotein IIb/IIIa inhibitors, but with less bleeding risk. (more…)
