Randomized Controlled TrialPlatelet inhibition with standard vs. lower maintenance dose of ticagrelor early after myocardial infarction (ELECTRA): a randomized, open-label, active-controlled pharmacodynamic and pharmacokinetic study.
Currently available data indicate that reduction of ticagrelor maintenance dose (MD) 1-3 years after acute myocardial infarction (AMI) not only provides sufficient platelet inhibition but also can improve ticagrelor's safety profile. The aim of this study was to compare the antiplatelet effect of reduced and standard ticagrelor MD in stable patients beginning 1 month after AMI. ⋯ NCT03251859.

Influence of intravenous fentanyl compared with morphine on ticagrelor absorption and platelet inhibition in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention: rationale and design of the PERSEUS randomized trial.
Recent evidence demonstrates that intravenous morphine significantly reduces absorption and delays onset of action of oral P2Y12 receptor inhibitors in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). We aimed to assess the influence of intravenous fentanyl compared with morphine on pharmacokinetics and pharmacodynamics of ticagrelor and its active metabolite (AR-C124910XX) in patients undergoing pPCI for STEMI. ⋯ PERSEUS will provide randomized data regarding the impact of fentanyl administration, in patients with STEMI undergoing pPCI, on platelet inhibition and ticagrelor absorption and total exposure.

Observational StudyTrends in cardiovascular and bleeding outcomes in acute coronary syndrome patients treated with or without proton-pump inhibitors during the introduction of novel P2Y12 inhibitors: a five-year experience from a single-centre observational registry.
Proton-pump inhibitors (PPIs) are commonly prescribed in acute coronary syndrome (ACS) patients on antiplatelet therapy. We studied PPI prescription in ACS patients in the era of novel P2Y12 inhibitors and assessed the association between PPI use and clinical outcomes. ⋯ In this single-centre registry, PPI prescription in ACS patients doubled between 2010 and 2014. PPI treatment at discharge was associated with a reduction in death, MI, or stroke at 30-days post-discharge, mainly driven by a reduction in MI. There were no differences gastrointestinal bleeding between patients treated with or without a PPI. PPI treatment may serve as a marker of improved therapies and outcome, rather than causing a reduction in cardiovascular events.
