BACKGROUND The cardiovascular safety and efficacy of many current antihyperglycemic agents, including saxagliptin, a dipeptidyl peptidase 4 (DPP-4) inhibitor, are unclear. METHODS We randomly assigned 16,492 patients with type 2 diabetes who had a history of, or were at risk for, cardiovascular events to receive saxagliptin or placebo and followed them(More)
BACKGROUND Thrombin potently activates platelets through the protease-activated receptor PAR-1. Vorapaxar is a novel antiplatelet agent that selectively inhibits the cellular actions of thrombin through antagonism of PAR-1. METHODS We randomly assigned 26,449 patients who had a history of myocardial infarction, ischemic stroke, or peripheral arterial(More)
BACKGROUND Gastrointestinal complications are an important problem of antithrombotic therapy. Proton-pump inhibitors (PPIs) are believed to decrease the risk of such complications, though no randomized trial has proved this in patients receiving dual antiplatelet therapy. Recently, concerns have been raised about the potential for PPIs to blunt the efficacy(More)
OBJECTIVES Our goal was to compare the safety and initial efficacy of AZD6140, the first reversible oral adenosine diphosphate receptor antagonist, with clopidogrel in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS). BACKGROUND AZD6140 achieves higher mean levels of platelet inhibition than clopidogrel in patients with stable(More)
CONTEXT Ranolazine is a novel antianginal agent that reduces ischemia in patients with chronic angina but has not been studied in patients with acute coronary syndromes (ACS). OBJECTIVE To determine the efficacy and safety of ranolazine during long-term treatment of patients with non-ST-elevation ACS. DESIGN, SETTING, AND PATIENTS A randomized,(More)
OBJECTIVES The purpose of this study is to evaluate the efficacy and safety of ticagrelor and clopidogrel in patients with acute coronary syndrome undergoing coronary artery bypass graft surgery (CABG), as a post-randomization strategy. BACKGROUND Ticagrelor is a novel, reversibly binding, oral, direct-acting P2Y(12)-receptor antagonist. In the PLATO(More)
CONTEXT Variants in the CYP2C19 gene influence the pharmacologic and clinical response to the standard 75-mg daily maintenance dose of the antiplatelet drug clopidogrel. OBJECTIVE To test whether higher doses (up to 300 mg daily) improve the response to clopidogrel in the setting of loss-of-function CYP2C19 genotypes. DESIGN, SETTING, AND PATIENTS(More)
BACKGROUND Ranolazine, a piperazine derivative, reduces ischemia via inhibition of the late phase of the inward sodium current (late I(Na)) during cardiac repolarization, with a consequent reduction in intracellular sodium and calcium overload. Increased intracellular calcium leads to both mechanical dysfunction and electric instability. Ranolazine reduces(More)
BACKGROUND Diabetes mellitus and heart failure frequently coexist. However, few diabetes mellitus trials have prospectively evaluated and adjudicated heart failure as an end point. METHODS AND RESULTS A total of 16 492 patients with type 2 diabetes mellitus and a history of, or at risk of, cardiovascular events were randomized to saxagliptin or placebo(More)
OBJECTIVES The aim of this study was to assess the prognostic performance of C-terminal provasopressin (copeptin), midregional pro-adrenomedullin (MR-proADM), and midregional pro-atrial natriuretic peptide (MR-proANP) in a large prospective cohort of patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). BACKGROUND Copeptin, MR-proADM,(More)
