BACKGROUND The incremental prognostic value of plasma levels of C-reactive protein (CRP) in relation to GRACE score has not been established in patients with acute coronary syndrome (ACS) with non-ST segment elevation. OBJECTIVE To test the hypothesis that CRP measurements at admission increases the prognostic value of GRACE score in patients with ACS. (More)
BACKGROUND The TIMI Score for ST-segment elevation myocardial infarction (STEMI) was created and validated specifically for this clinical scenario, while the GRACE score is generic to any type of acute coronary syndrome. OBJECTIVE Between TIMI and GRACE scores, identify the one of better prognostic performance in patients with STEMI. METHODS We included(More)
BACKGROUND An adequate door-to-balloon time (<120 minutes) is the necessary condition for the efficacy of primary angioplasty in infarction to translate into effectiveness. OBJECTIVE To describe the effectiveness of a quality of care protocol in reducing the door-to-balloon time. METHODS Between May 2010 and August 2012, all individuals undergoing(More)
Background: The accuracy of zero coronary calcium score as a filter in patients with chest pain has been demonstrated at the emergency room and outpatient clinics, populations with low prevalence of coronary artery disease (CAD). Objective: To test the gatekeeping role of zero calcium score in patients with chest pain admitted to the coronary care unit(More)
Background: Currently, there is no validated multivariate model to predict probability of obstructive coronary disease in patients with acute chest pain. Objective: To develop and validate a multivariate model to predict coronary artery disease (CAD) based on variables assessed at admission to the coronary care unit (CCU) due to acute chest pain. (More)
BACKGROUND The ACUITY and CRUSADE scores are validated models for prediction of major bleeding events in acute coronary syndrome (ACS). However, the comparative performances of these scores are not known. OBJECTIVE To compare the accuracy of ACUITY and CRUSADE in predicting major bleeding events during ACS. METHODS This study included 519 patients(More)
AIM To test accuracy and reproducibility of gestalt to predict obstructive coronary artery disease (CAD) in patients with acute chest pain. METHODS We studied individuals who were consecutively admitted to our Chest Pain Unit. At admission, investigators performed a standardized interview and recorded 14 chest pain features. Based on these features, a(More)
