BACKGROUND Management of acute coronary syndromes (ACS) should be guided by an estimate of patient risk. OBJECTIVE To develop a simple model to assess the risk for in-hospital mortality for the entire spectrum of ACS treated in general clinical practice. METHODS A multivariable logistic regression model was developed using 11 389 patients (including 509(More)
OBJECTIVE To develop a clinical risk prediction tool for estimating the cumulative six month risk of death and death or myocardial infarction to facilitate triage and management of patients with acute coronary syndrome. DESIGN Prospective multinational observational study in which we used multivariable regression to develop a final predictive model, with(More)
AIMS To establish whether the addition of enoxaparin (a low-molecular-weight heparin) to streptokinase therapy improves early and sustained coronary patency and clinical outcome in patients with evolving myocardial infarction. METHODS AND RESULTS A total of 496 patients with acute myocardial infarction treated with streptokinase were randomized to an(More)
CONTEXT Enoxaparin has demonstrated advantages over unfractionated heparin in low- to moderate-risk patients with non-ST-segment elevation acute coronary syndromes (ACS) treated with a conservative strategy. OBJECTIVES To compare the outcomes of patients treated with enoxaparin vs unfractionated heparin and to define the role of enoxaparin in patients(More)
BACKGROUND Cangrelor, a nonthienopyridine adenosine triphosphate analogue, is an intravenous blocker of the adenosine diphosphate receptor P2Y(12). This agent might have a role in the treatment of patients who require rapid, predictable, and profound but reversible platelet inhibition. METHODS We performed a large-scale international trial comparing(More)
BACKGROUND Antithrombotic therapy with heparin plus aspirin reduces the rate of ischemic events in patients with unstable coronary artery disease. Low-molecular-weight heparin has a more predictable anticoagulant effect than standard unfractionated heparin, is easier to administer, and does not require monitoring. METHODS In a double-blind,(More)
CONTEXT Accurate estimation of risk for untoward outcomes after patients have been hospitalized for an acute coronary syndrome (ACS) may help clinicians guide the type and intensity of therapy. OBJECTIVE To develop a simple decision tool for bedside risk estimation of 6-month mortality in patients surviving admission for an ACS. DESIGN, SETTING, AND(More)
AIMS Despite advances in the treatment of acute coronary syndromes based on randomized trial data and published guidelines, the extent to which such treatments are applied in practice remains uncertain. Data from clinical trials derive from selected geographical areas and in highly selected populations of patients, and hence may not reflect the overall(More)
AIM Many patients who are eligible for acute reperfusion therapy receive it after substantial delays or not at all. We wanted to determine whether over the years more patients are receiving reperfusion therapy. METHODS AND RESULTS This analysis is based on 10 954 patients with ST elevation or left bundle-branch block presenting within 12 h of symptom(More)
BACKGROUND Following acute coronary syndrome (ACS), the risk for future cardiovascular events is high and is related to levels of low-density lipoprotein cholesterol (LDL-C) even within the setting of intensive statin treatment. Proprotein convertase subtilisin/kexin type 9 (PCSK9) regulates LDL receptor expression and circulating levels of LDL-C.(More)
