Low Dose Ticagrelor Versus Low Dose Prasugrel in Patients With Prior Myocardial Infarction

Summary

Taken together the results from DAPT and PEGASUS-TIMI54, it appears that physicians may consider extending beyond 1 year or reinitiating treatment with a thienopyridine or ticagrelor 60mg bid in patients with a prior MI and features of high ischemic and low bleeding risk. Comparative clinical or pharmacodynamic studies, however, between prasugrel 5 mg od and ticagrelor 60 mg bid in the chronic phase of stable post MI patients have not been performed. In light of this, we believe that a dedicated pharmacodynamic study of ticagrelor 60 bid mg vs prasugrel 5 mg od in a PEGASUS-like population would be informative for the practicing clinician, thus setting the rationale for conducting this specifically designed investigation.
