STUDY OBJECTIVE We sought to determine whether electron-beam computed tomography (EBCT) could be used as a triage tool in the emergency department for patients with angina-like chest pain, no known history of coronary disease, normal or indeterminate ECG findings, and normal initial cardiac enzyme concentrations. METHODS We conducted a prospective(More)
OBJECTIVES A pilot study was designed to assess the safety of combined intravenous adenosine and lidocaine in patients with acute myocardial infarction and to estimate the likelihood of a beneficial effect on final infarct size. BACKGROUND Adenosine plus lidocaine reduces infarct size in animals, but the safety and efficacy in human beings is unknown. (More)
OBJECTIVE To determine the long-term outcome of computed tomographic (CT) quantification of coronary artery calcium (CAC) used as a triage tool for patients presenting with chest pain to an emergency department (ED). PATIENTS AND METHODS Patients (men aged 30-62 years and women aged 30-65 years) with chest pain and low-to-moderate probability of coronary(More)
BACKGROUND Exercise treadmill testing (ETT) has been standard for evaluating outpatients at risk for cardiovascular events. Few studies have demonstrated its prognostic usefulness in emergency department chest pain units or have used the Duke score [(exercise duration in minutes) - (5 x ST-segment deviation in millimeters) - (4 x treadmill angina index)] to(More)
STUDY OBJECTIVE An emergency department (ED) observation unit protocol for the management of acute onset atrial fibrillation is compared with routine hospital admission and management. METHODS Adult patients presenting to the ED with atrial fibrillation of less than 48 hours' duration without hemodynamic instability or other comorbid conditions requiring(More)
BACKGROUND Reports have demonstrated an association between statin therapy during the first day of hospitalization for acute myocardial infarction (AMI) and reduced mortality. There are little data about whether early statin therapy reduces risk of CHF and alters timing of death. METHODS We identified 3226 consecutive patients with AMI from 1993 through(More)
Electron beam computed tomography (EBCT) allows viszalization and quantification of calcium in the coronary arteries. This has been demonstrated to correlate well with the overall plaque burden in the coronary arteries. EBCT is, therefore, well suited for the detection of early stages of coronary atherosclerosis. Especially in asymptomatic patients with(More)

Background: Chest pain results in more than six million emergency department (ED) visits each year in the USA. We will discuss the current state of chest pain evaluation in the ED and show data from a prospective blinded study that suggests that coronary calcification scanning by electron beam computed tomography (EBCT) can be used safely in this evaluation(More)
