Methods and results: MIRTOS is a multicenter study of ticagrelor versus clopidogrel in STEMI subjects treated with fibrinolysis. We enrolled 335 patients <75 years old with STEMI eligible for thrombolysis, of which 167 were randomized to receive clopidogrel and 168 to receive ticagrelor together with thrombolysis. Primary outcome was the difference in post-PCI corrected TIMI frame count (CTFC). All clinical events were recorded in a 3-month follow-up period. From the 335 patients that were randomized, 259 underwent PCI (129 clopidogrel and 130 ticagrelor) and 154 angiographies were analyzable for study primary endpoint. No significant difference was found between the clopidogrel (n=85) and ticagrelor (n=69) groups for CTFC (24.33±17.35 vs 28.33±17.59, p=0.10). No significant differences were observed in MACE and major bleeding events between randomization groups (OR 2.0, 95% CI 0.18-22.2, p=0.99). Conclusions: Thrombolysis with ticagrelor in patients <75 years old was not able to demonstrate superiority compared to clopidogrel in terms of microvascular injury, while there was no difference between the 2 groups in MACE and major bleeding events.
