BACKGROUND Variation in and irreversibility of platelet inhibition with clopidogrel has led to controversy about its optimum dose and timing of administration in patients with acute coronary syndromes. We compared ticagrelor, a more potent reversible P2Y12 inhibitor with clopidogrel in such patients. METHODS At randomisation, an invasive strategy was(More)
AIMS patients with diabetes mellitus (DM) have high platelet reactivity and are at increased risk of ischaemic events and bleeding post-acute coronary syndromes (ACS). In the PLATelet inhibition and patient Outcomes (PLATO) trial, ticagrelor reduced the primary composite endpoint of cardiovascular death, myocardial infarction, or stroke, but with similar(More)
MicroRNAs are small non-coding RNAs that are detectable in plasma and serum. Circulating levels of microRNAs have been measured in various studies related to cardiovascular disease. Heparin is a potential confounder of microRNA measurements due to its known interference with polymerase chain reactions. In this study, platelet-poor plasma was obtained from(More)
BACKGROUND In the PLATO trial of ticagrelor versus clopidogrel for treatment of acute coronary syndromes, ticagrelor reduced the composite outcome of cardiovascular death, myocardial infarction, and stroke, but increased events of major bleeding related to non-coronary artery bypass graft (CABG). CYP2C19 and ABCB1 genotypes are known to influence the(More)
BACKGROUND Ticagrelor is the first reversibly binding oral P2Y(12) receptor antagonist. This is the first study to compare the onset and offset of platelet inhibition (IPA) with ticagrelor using the PLATO (PLATelet inhibition and patient Outcomes) trial loading dose (180 mg) with a high loading dose (600 mg) of clopidogrel. METHODS AND RESULTS In a(More)
BACKGROUND In the Platelet Inhibition and Patient Outcomes (PLATO) trial, a prespecified subgroup analysis showed a significant interaction between treatment and region (P=0.045), with less effect of ticagrelor in North America than in the rest of the world. METHODS AND RESULTS Reasons for the interaction were explored independently by 2 statistical(More)
BACKGROUND Reduced renal function is associated with a poorer prognosis and increased bleeding risk in patients with acute coronary syndromes and may therefore alter the risk-benefit ratio with antiplatelet therapies. In the Platelet Inhibition and Patient Outcomes (PLATO) trial, ticagrelor compared with clopidogrel reduced the primary composite end point(More)
OBJECTIVE To evaluate efficacy and safety outcomes in patients in the PLATelet inhibition and patient Outcomes (PLATO) trial who at randomisation were planned for a non-invasive treatment strategy. DESIGN Pre-specified analysis of pre-randomisation defined subgroup of prospective randomised clinical trial. SETTING 862 centres in 43 countries. (More)
