Identifying acute coronary syndrome is a difficult task in the emergency department because symptoms may be atypical and the electrocardiogram has low sensitivity. In this prospective cohort study done in a tertiary community emergency hospital, we developed and tested a neural diagnostic tree in 566 consecutive patients with chest pain and no ST-segment(More)
AIMS This study was undertaken to determine the diagnostic value of admission B-type natriuretic peptide (BNP) for acute myocardial infarction (AMI) in patients with acute chest pain and no ST-segment elevation. METHODS AND RESULTS A prospective study with 631 consecutive patients was conducted in the emergency department. Non-ST elevation AMI was present(More)
Management of chest pain patients in the emergency department has been a dilemma because of difficulty in identifying those who can be immediately discharged and those who need to be hospitalized. We assessed the efficacy of a probability stratification model and a systematic diagnostic strategy in 1003 consecutive chest pain patients prospectively(More)
BACKGROUND The prognostic importance of early measurement of B-type natriuretic peptide (BNP) in patients with acute chest pain while the diagnosis is still uncertain is unknown. We determined the prognostic value of BNP in these patients immediately after presenting to the emergency department. METHODS Seven hundred and twenty-three consecutive(More)
In a study conducted at St Bartholomew's Hospital between 1972 and 1982, using moderately intensive therapy (OPAL/HEAV'D), a low blast count at presentation (less than 10 x 10(9) 1(-1)) and common ALL (C-ALL) phenotype correlated favourably with duration of remission. Fifty-four patients (age range 15-57, median 32) subsequently received a modification of(More)
PURPOSE To evaluate the clinical findings and complementary investigation to support the diagnosis of arrhythmogenic right ventricular dysplasia. METHODS Six males with a mean age of 40 years old with episodes of sustained ventricular tachycardia with left bundle branch block pattern. All patients were submitted to a clinical investigation, EKG X rays and(More)
OBJECTIVE To evaluate the efficiency of a systematic diagnostic approach in patients with chest pain in the emergency room in relation to the diagnosis of acute coronary syndrome (ACS) and the rate of hospitalization in high-cost units. METHODS One thousand and three consecutive patients with chest pain were screened according to a preestablished process(More)
It is estimated that 5 to 8 million individuals with chest pain or other symptoms suggestive of myocardial ischemia are seen each year in emergency departments (ED) in the United States 1,2, which corresponds to 5 to 10% of all visits 3,4. Most of these patients are hospitalized for evaluation of possible acute coronary syndrome (ACS). This generates an(More)
In a prospective study 51 consecutive patients who survived the acute phase of inferior wall myocardial infarction underwent coronary arteriography. Eleven patients developed some degree of atrioventricular (AV) block in the acute phase of infarction that disappeared within a few days and was considered by electrocardiographic analysis to be located in the(More)
OBJECTIVE To assess safety, feasibility, and the results of early exercise testing in patients with chest pain admitted to the emergency room of the chest pain unit, in whom acute myocardial infarction and high-risk unstable angina had been ruled out. METHODS A study including 1060 consecutive patients with chest pain admitted to the emergency room of the(More)
