OBJECTIVE: We aimed to characterize outcomes associated with cangrelor administration used in an antiplatelet bridging strategy in real-world clinical scenarios within a large academic medical system.
BACKGROUND: Cangrelor has been used for antiplatelet bridging in perioperative settings or for patients unable to take oral medications. Prior studies in these settings have reported bleeding rates from 0%-40%.
METHODS: Patients were retrospectively identified via chart review and included if they were over 18 years old, had coronary or peripheral arterial stents, and had received at least 1 hour of cangrelor infusion during inpatient admission. The primary endpoint was Bleeding Academic Research Consortium (BARC) 3-5 bleeding during cangrelor infusion or within 48 hours of discontinuation; secondary endpoints were bleeding events defined by Thrombolysis in Myocardial Infarction (TIMI), Global Use of Strategies to Open Occluded Arteries (GUSTO), and International Society on Thrombosis and Hemostasis (ISTH) criteria, as well as BARC 2 bleeding.
RESULTS: Thirty-one patients met the inclusion criteria. Cangrelor indications were bridging to procedure in 22 patients (71.0%) and inability to take oral P2Y12 inhibitors in 9 patients (29.0%). Twenty-three patients (74.2%) were men, 11 patients (35.5%) were in cardiogenic shock, and 4 patients (12.9%) were on extracorporeal membrane oxygenation (ECMO) at the time of administration. No patients received cangrelor for routine percutaneous coronary intervention. Of the 31 patients, 13 (41.9%) had BARC 3-5 bleeding and 7 (22.6%) expired during hospitalization. All 4 patients on ECMO suffered BARC 3-5 bleeding.
CONCLUSIONS: We reviewed the use of cangrelor for antiplatelet bridging in real-world clinical scenarios and observed higher rates of clinically significant bleeding than seen in other similar studies. Our study suggests careful consideration when using cangrelor in a sick patient population.
