Antiplatelet Pharmacogenomic Assessment in a Case of Coronary Artery Bypass

Published on: 2017-02-08


If not contraindicated, it is reasonable to use DAPT, starting in the CABG postoperative period, using ASA in association with clopidogrel. There is no specific guideline indicating pharmacogenomic testing for DAPT, but the FDA recommends it when using clopidogrel. In the present case pharmacogenomics was used for the evaluation of DAPT one year after CABG. The results indicate that despite the platelet hyper-responsiveness to ADP, clopidogrel might not be indicated, due to an increased P-gp dependent intestinal efflux, and its use should be reconsidered to substitute it with a different drug, like ticlopidine, or to administer it concomitant with P-gp antagonists.
