BACKGROUND Admission rates among patients presenting to emergency departments with possible acute coronary syndromes are high, although for most of these patients, the symptoms are ultimately found not to have a cardiac cause. Coronary computed tomographic angiography (CCTA) has a very high negative predictive value for the detection of coronary disease,(More)
BACKGROUND Disturbances of sleep EEG are prominent in alcoholic patients, persist into recovery, and recently have been found to predict those alcoholics who are most likely to relapse. Increasing evidence indicates that there are ethnic differences in sleep EEG and that African-Americans may be at elevated risk for disordered sleep. METHODS This study(More)
OBJECTIVES In a large U.S. sample, this study measured the presentation features, testing, treatment strategies, and outcomes of patients diagnosed with pulmonary embolism (PE) in the emergency department (ED). BACKGROUND No data have quantified the demographics, clinical features, management, and outcomes of outpatients diagnosed with PE in the ED in a(More)
The objective of this study was to evaluate the effects of nocturnal sleep, partial night sleep deprivation, and sleep stages on catecholamine and interleukin-2 (IL-2) levels in humans. Circulating levels of catecholamines and IL-2 were sampled every 30 min during 2 nights: undisturbed, baseline sleep and partial sleep deprivation-late night (PSD-L; awake(More)
BACKGROUND Epidemiological data indicate that among alcoholics African-American men have higher rates of infections compared with white alcoholics. Alcohol is thought to reduce natural killer (NK) cell responses and to alter cellular immunity by changing the relative balance of Th1 versus Th2 cytokine response profiles. However, translation of these basic(More)
BACKGROUND The HEART Pathway is a decision aid designed to identify emergency department patients with acute chest pain for early discharge. No randomized trials have compared the HEART Pathway with usual care. METHODS AND RESULTS Adult emergency department patients with symptoms related to acute coronary syndrome without ST-elevation on ECG (n=282) were(More)
OBJECTIVES The aim of this study was to compare outcomes in patients receiving consistent unfractionated heparin (UFH)/enoxaparin (ENOX) therapy and in those switched at randomization to bivalirudin monotherapy. BACKGROUND Crossover between UFH and ENOX has been associated with increased adverse outcomes in patients with acute coronary syndromes. The(More)
AIMS Results from investigations in one area of the world may not translate to another if patient characteristics and practices differ. We examine differences in the presentation and management of emergency department (ED) patients with dyspnoea from acute heart failure syndromes (AHFS) between the USA, Western Europe, and Eastern Europe. METHODS AND(More)
STUDY OBJECTIVE In patients presenting to the emergency department (ED) with an initial diagnostic impression of noncardiac chest pain, we determine the 30-day incidence of adverse cardiac events and characteristics associated with those events. METHODS The multicenter, prospectively collected Internet Tracking Registry for Acute Coronary Syndromes (i*tr(More)
BACKGROUND In 2001-2002, the American Heart Association and National Heart, Lung, and Blood Institute initiated national campaigns with the aim of increasing women's awareness of their risk of heart disease, with particular focus on women aged 40 to 60 years. Our aim is to determine if these women's awareness campaigns were associated with a reduction in(More)
