Brief summary
This prospective registry was designed to carefully investigate the pharmacodynamic (PD) effects of cangrelor in all patients undergoing percutaneous coronary intervention (PCI).
Detailed description
There is huge interest in achieving fast and immediate antiplatelet effect at the time of PCI, particularly in acute myocardial infarction and Cangrelor is an intravenous antagonist of the P2Y12 receptor characterized by rapid, potent, predictable, and reversible platelet inhibition. However, there are limited pharmacodynamic data exploring the effects of this drug in the various clinical settings at the approved dosages and with current gold standard methods for testing platelet reactivity. More importantly, there are no data on rates and predictors of high residual platelet reactivity (HRPR) in patients treated with cangrelor. Therefore the present study aims at building up a large prospective registry of pharmacodynamic data obtained by light transmittance aggregometry (LTA), multiplate analysis and verifynow system in patients undergoing PCI and receiving cangrelor. This study is designed as a single-center prospective registry. Investigators at University Hospital of Naples Federico II will enroll patients, collect blood samples, perform platelet function tests and collect clinical and demographic information.
Interventions
All patients receiving Cangrelor during PCI will be enrolled and analyzed for platelet function tests.
