Editorial referring to the article: Validation of the Grace Risk Score to Predict In-Hospital and 6-Month Post-Discharge Mortality in Patients with Acute Coronary Syndrome Acute Coronary Syndrome (ACS) is the most common cause of death worldwide. Nevertheless, ACS represents a heterogenous group of diseases, encompassing since low-risk unstable angina (30-day mortality below 1%), until patients with ST-elevation myocardial infarction (STEMI) and cardiogenic shock (30-day mortality around 50%). Multivariable prediction models have been developed to classify short-term and long-term risk of […]

Abstract Introduction: Risk scores evaluate pre-operatory risk and present support for clinical decisions, however the performance of these tools in samples different from the original ones remains unclear. Objectives: Investigate the external validity of risk scores (STS and Euroscore) in cardiac surgery and the predictive performance of clinical features derived from the sample. Methods: Retrospective Cohort study conducted between October, 2010, and April, 2015. We used logistic regression to identify risk factors for hospital morbidity. The sample was divided for […]
