Exploring the reduction in myocardial infarctions in the PLATO trial: which patients benefited on ticagrelor vs. clopidogrel?
Ticagrelor showed significant reductions in myocardial infarctions (MIs) compared to clopidogrel in the Platelet Inhibition and Patient Outcomes (PLATO) trial. However, there was no explanation as to whether there was an equal distribution of benefit throughout acute coronary syndrome (ACS) types. ⋯ Ticagrelor significantly reduced MIs compared to clopidogrel only in STEMI patients, with those receiving early PCI having worse outcomes with ticagrelor. Despite, NSTEMI patients showing no significant reduction in MI with ticagrelor vs. clopidogrel, CV mortality was significantly reduced. In summary, we cannot be sure what is driving the STEMI-MI benefit, the NSTEMI-CV mortality benefit, nor the overall mortality benefit for ticagrelor-treated patients compared to clopidogrel treated patients.
