Comparison of Heart Rates in Patients Initiated on Ticagrelor Versus Other P2Y12 Inhibitors After an Inferior ST Elevation Myocardial Infarction (STEMI).

Background: P2Y12 inhibitors have differing associations of bradyarrhythmias. Ticagrelor has been shown to increase adenosine plasma concentrations leading to increases in bradyarrhythmias. While clopidogrel and prasugrel have not been shown to have any association with bradyarrhythmias.

Multicenter comparison of antiplatelet treatment strategies for urgent/emergent neuroendovascular stenting.

Background: Emergent neuroendovascular stenting presents challenges for the utilization of antiplatelet agents.

Methods: This was a multicenter, retrospective cohort of patients who underwent emergent neuroendovascular stenting. The primary endpoints were thrombotic and bleeding events in relation to the timing of antiplatelet administration, route of administration, and choice of intravenous (IV) agent and the study investigated practice variability in antiplatelet utilization.

Multicenter Comparison of the Safety and Efficacy of Clopidogrel Versus Ticagrelor for Neuroendovascular Stents.

Background: Dual antiplatelet therapy (DAPT) is commonly employed for neuroendovascular stenting due to the significant risk of thromboembolism. Clopidogrel and aspirin are most often selected as initial DAPTs; however, there is limited literature available to support guidance of DAPT in this setting. The objective of this study was to evaluate safety and efficacy in patients whose final regimen included either DAPT with aspirin and clopidogrel (DAPT-C) or DAPT with aspirin and ticagrelor (DAPT-T).

The Reemergence of Ketamine for Treatment in Critically Ill Adults.

Objectives: To assess the evidence and discuss the risks and clinical relevance of ketamine for the treatment of various disease states impacting the adult critically ill population.

Data Sources: A literature review was performed using PubMed evaluating primary literature published until August 2018.

Study Selection: Case reports, observational studies (cohort, case-control), and randomized controlled trials involving patients 18 years and older in a nonperioperative setting using either IV or intramuscular ketamine were included for analysis.

A meta-analysis of efficacy and safety of genotype-guided versus standard of care treatment strategies in selecting antiplatelet therapy in patients with acute coronary syndrome.

Background: Previous studies have shown similar rates of major adverse cardiovascular events (MACE) in acute coronary syndrome (ACS) patients, treated with P2Y inhibitors based on genotype guidance compared to standard treatment. However, given lower than expected event rates, these studies were underpowered to assess hard outcomes. We sought to systematically analyze this evidence using pooled data from multiple studies.
