3. TICO (Ticagrelor With or Without Aspirin in Acute Coronary Syndrome After Percutaneous Coronary Intervention) trial
Ticagrelor monotherapy after 3 months of DAPT was superior at preventing ischemia and bleeding after PCI for ACS.
Patients undergoing PCI for ACS were randomized to ticagrelor monotherapy after 3 months of DAPT versus standard therapy.
Among ACS patients who underwent PCI with an ultrathin biodegradable-polymer sirolimus-eluting stent, ticagrelor monotherapy after 3 months of DAPT was superior to standard therapy of DAPT for 12 months. Ticagrelor monotherapy was effective at preventing net composite ischemic and bleeding events.
Ticagrelor monotherapy appears to be an emerging strategy, especially for patients with increased bleeding risk, after a short duration of DAPT.
Unlike TWILIGHT trial, TICO included patients with STEMI also and hence widens the spectrum of ticagrelor montherapy use in acute coronary syndrome setting.
Taken together, the observations from TICO-STEMI appear to further highlight the need for optimal distinction between the risk factors of bleeding and ischemia in post-PCI patients. This is not an easy endeavour given the documented overlap between the two. However, it is a goal worth pursuing, as a proper stratification tool may have the capacity to improve prognosis given that both thrombotic and bleeding events are associated with increased mortality.
