Why the study?
Although clopidogrel remains guideline-recommended in STEMI patients undergoing thrombolysis, the appropriateness of ticagrelor in the peri-thrombolytic phase remains open to debate.
Does ticagrelor improve efficacy and safety compared to clopidogrel in patients with ST-segment elevation myocardial infarction undergoing thrombolytic therapy?
Does ticagrelor improve efficacy and safety compared to clopidogrel in patients with ST-segment elevation myocardial infarction undergoing thrombolytic therapy?
Ticagrelor offers superior platelet inhibition without increased bleeding risk compared to clopidogrel in the peri-thrombolytic phase of STEMI, challenging current guidelines that favor clopidogrel.
May support ticagrelor preference post-thrombolysis in STEMI; leaves open prospective RCTs before practice change.
Recent years have seen ticagrelor, a potent P2Y12 inhibitor, emerge as a significant advancement in the peri-thrombolytic management of patients with ST-segment elevation myocardial infarction (STEMI), offering a promising alternative to traditional antiplatelet drugs like clopidogrel. This review critically examines the efficacy and safety of ticagrelor during the peri-thrombolytic phase in STEMI patients, drawing on evidence from key clinical trials such as TREAT and MIRTOS, as well as other relevant studies. These investigations underscore ticagrelor's superior platelet inhibition capabilities, which are crucial for minimizing thrombotic complications post-thrombolysis without increasing bleeding risks. Despite its potential, clopidogrel remains the guideline-recommended choice for such patients, leaving the appropriateness of ticagrelor in this context open to debate. By summarizing the current evidence and identifying gaps in our understanding, this study advocates for targeted research to clarify the long-term benefits and optimal deployment of ticagrelor, highlighting its evolving significance in cardiovascular care.
