- Our study supports the feasibility of using rapid CYP2C19 genotyping among both patients with stable and acute coronary syndrome undergoing diagnostic coronary angiography, with intent to undergo ad hoc PCI, in real-world clinical practice.
- Rapid bedside genetic testing assay allows for very rapid turnaround times of results, with patients approached the same day of their procedure and availability of CYP2C19 genotypes within 1 h of sampling and before patients undergoing PCI.
- Among carriers of CYP2C19 loss-of-function alleles undergoing PCI there were no differences in levels of platelet inhibition between prasugrel and ticagrelor (loading and maintenance dosing).
