Platelet function testing to time surgery in patients on dual antiplatelet therapy?

SummaryIn patients pretreated with P2Y12 receptor inhibitors who need to undergo non-emergent cardiac or major non-cardiac surgery, current guidelines of the European Society of Cardiology recommend postponing surgery for at least five days after last intake of clopidogrel or ticagrelor, and for seven days after last intake of prasugrel, unless there is high risk of ischemic events. However, a fixed five to seven days preoperative waiting period may be challenged, in the presence of inter-individual variability in on-treatment platelet reactivity. Therefore, Society of Thoracic Surgeons guidelines suggest to bas…
