Background: Although the TIMI score is the one most frequently used in acute coronary syndromes (ACS) without ST-segment elevation, the GRACE score has potential prognostic superiority, as it was created based on an observational registry, part of the variables is treated in a semi-quantitative form and renal function is taken into account in its calculation.
Objective: To test the hypothesis that the GRACE risk score has superior in-hospital prognostic value, when compared to the TIMI score in patients admitted with ACS.
Methods: Individuals with unstable angina or myocardial infarction without ST-segment elevation, consecutively admitted at the Coronary Unit between August 2007 and January 2009, were included in the study.
Background: Pulmonary embolism is associated with high mortality in patients with hypotension or circulatory shock. However, the association between some clinical variables and mortality is still unclear in hemodynamically stable patients.
Objectives: To derive an in-hospital mortality risk stratification model in hemodynamically stable patients with pulmonary embolism.
Objective: To evaluate the association between troponin I concentrations (TnI) in patients submitted to elective percutaneous coronary interventions (PCI) and adverse coronary events (ACE) during a six month follow-up period.
Methods: One hundred and eleven patients who had been submitted to an elective PCI were consecutively selected during a one year timeframe. The patients had stable angina (SA), unstable angina (UA) or silent ischemia (SI) and were asymptomatic for at least 72 hours before the procedure.

Objective: To evaluate the performance of the turbidimetric method of C-reactive protein (CRP) as a measure of low-grade inflammation in patients admitted with non-ST elevation acute coronary syndromes (ACS).
Methods: Serum samples obtained at hospital arrival from 68 patients (66 11 years, 40 men), admitted with unstable angina or non-ST elevation acute myocardial infarction were used to measure CRP by the methods of nephelometry and turbidimetry.
Results: The medians of C-reactive protein by the turbidimetric and nephelometric methods were 0.
Background: Approximately three-quarters of cardiovascular disease deaths in the world come from developing countries, and acute myocardial infarction (AMI) is an important cause of death. Brazil is one of the largest countries in Latin America and the contemporary evaluation of risk factors for AMI is crucial for a more efficacious disease management.
Methods: The Acute Myocardial Infarction Risk Factor Assessment in Brazil (AFIRMAR) study is a case-control, hospital-based study involving 104 hospitals in 51 cities in Brazil, designed to evaluate risk factors for a first ST-segment elevation AMI.
