BACKGROUND Considerable variability in mortality risk exists among patients with ST-elevation myocardial infarction (STEMI). Complex multivariable models identify independent predictors and quantify their relative contribution to mortality risk but are too cumbersome to be readily applied in clinical practice. METHODS AND RESULTS We developed and(More)
CONTEXT Detectable levels of cardiac troponin T (cTnT) are strongly associated with structural heart disease and increased risk of death and adverse cardiovascular events; however, cTnT is rarely detectable in the general population using standard assays. OBJECTIVES To determine the prevalence and determinants of detectable cTnT in the population using a(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 Unfractionated heparin is often used as adjunctive therapy with fibrinolysis in patients with ST-elevation myocardial infarction. We compared a low-molecular-weight heparin, enoxaparin, with unfractionated heparin for this purpose. METHODS We randomly assigned 20,506 patients with ST-elevation myocardial infarction who were scheduled to undergo(More)
s in PubMed), and more liberal use of summary recommendation tables (with references that support LOE) to serve as a quick reference. In April 2011, the Institute of Medicine released 2 reports: Finding What Works in Health Care: Standards for Systematic Reviews and Clinical Practice Guidelines We Can Trust.2,3 It is noteworthy that the IOM cited ACCF/AHA(More)
BACKGROUND ST2 is a member of the interleukin-1 receptor family with a soluble form that is markedly upregulated on application of biomechanical strain to cardiac myocytes. Circulating ST2 levels are elevated in the setting of acute myocardial infarction, but the predictive value of ST2 independent of traditional clinical factors and of an established(More)
BACKGROUND In the setting of an acute coronary syndrome (ACS), anemia has the potential to worsen myocardial ischemia; however, data relating anemia to clinical outcomes in ACS remain limited. METHODS AND RESULTS We examined the association between baseline hemoglobin values and major adverse cardiovascular events through 30 days in 39,922 patients(More)
