We aim to externally validate the Ottawa subarachnoid hemorrhage (OSAH) clinical decision rule. This rule identifies patients with acute nontraumatic headache who require further investigation. We conducted a medical record review of all patients presenting to the emergency department (ED) with headache from January 2011 to November 2013. Per the OSAH rule, patients with any of the following predictors require further investigation: age 40 years or older, neck pain, stiffness or limited flexion, loss of consciousness, onset during exertion, or thunderclap...

BACKGROUND: Delirium is common, leads to other adverse outcomes, and is costly. However, it often remains unrecognized in most clinical settings. The Confusion Assessment Method (CAM) is the most widely used diagnostic algorithm, and operationalizing its features would be a substantial advance for clinical care. OBJECTIVE: To derive the 3D-CAM, a new 3-minute diagnostic assessment for CAM-defined delirium, and validate it against a clinical reference standard. DESIGN: Derivation and validation study...

BACKGROUND: Existing models for outcome after percutaneous coronary interventions (PCIs) lack assessment of long-term prognosis. Our goal was to derive 1- and 5-year mortality and mortality/myocardial infarction (MI) risk models for PCI outcomes from simple, easily obtainable clinical and laboratory variables. METHODS AND RESULTS: Using the Mayo Clinic registry, we analyzed long-term mortality and mortality/MI following PCIs on 9165 unique patients from January 1, 2001, through December 31, 2007...

BACKGROUND: Current risk models predict in-hospital mortality after either coronary artery bypass graft surgery or percutaneous coronary interventions separately, yet the overlap suggests that the same variables can define the risks of alternative coronary reperfusion therapies. Our goal was to seek a preprocedure risk model that can predict in-hospital mortality after either percutaneous coronary intervention or coronary artery bypass graft surgery. METHODS AND RESULTS: We tested the ability of the recently validated, integer-based Mayo Clinic Risk Score (MCRS) for percutaneous coronary intervention, which is based solely on preprocedure variables (age, creatinine, ejection fraction, myocardial infarction < or = 24 hours, shock, congestive heart failure, and peripheral vascular disease), to predict in-hospital mortality among 370,793 patients in the Society of Thoracic Surgeons database undergoing isolated coronary artery bypass graft surgery from 2004 to 2006...

OBJECTIVES: We sought to validate the recently proposed Mayo Clinic risk score model for complications after percutaneous coronary interventions (PCI), using an independent data set. BACKGROUND: The Mayo Clinic risk score has eight simple clinical and angiographic variables for the prediction of complications defined as either death, Q-wave myocardial infarction, emergent or urgent coronary artery bypass graft surgery, or cerebrovascular accident after PCI. External validation using an independent data set is lacking...

The early diagnosis of acute coronary syndrome (ACS) remains challenging, and a considerable proportion of patients are diagnosed with "possible" ACS on admission. The Global Registry of Acute Coronary Events (GRACE/GRACE(2)) and Canadian Registry of Acute Coronary Events (CANRACE) enrolled 16,618 Canadian patients with suspected ACS in 1999 to 2008. We compared the demographic and clinical characteristics, use of cardiac procedures, prognostic accuracy of the GRACE risk score, and in-hospital outcomes between patients given an admission diagnosis of "definite" versus "possible" ACS by the treating physician...

OBJECTIVE: : The ability to risk stratify patients presenting to the emergency department (ED) with potential acute coronary syndrome (ACS) is critical. Several risk scores for patients with definite ACS have been developed, but only the TIMI risk score has been shown to risk stratify ED patients with potential ACS. We compared the prognostic value of the GRACE and PURSUIT risk scores to the TIMI score in the broader ED patient population presenting with potential ACS. METHODS: : We performed a secondary analysis of a prospective cohort study that enrolled patients who presented to the ED with potential ACS...

BACKGROUND: The Braunwald classification and TIMI (Thrombolysis In Myocardial Infarction) risk score are used to stratify cardiovascular risk in patients with unstable angina (UA). However, these scores have a limited capacity in the practice of cardiology. OBJECTIVES: This study sought to develop a new score, based on blood biomarkers and coronary computed tomographic angiography (CCTA) characteristics, for patients with UA. PATIENTS AND METHODS: The study group consisted of 201 patients with confirmed UA...

The Thrombolysis in Myocardial Infarction (TIMI) score, derived from unstable angina/non-ST-segment elevation acute myocardial infarction patient population, predicts 14-day cardiovascular events. It has been validated in emergency department (ED) patients with potential acute coronary syndrome with respect to 30-day outcomes. Our objective was to determine whether the initial TIMI score could risk stratify ED patients with potential acute coronary syndrome with respect to the 1-year outcomes. This was a prospective cohort study of patients presenting to the ED with chest pain who underwent electrocardiography...

OBJECTIVES: This study attempted to prospectively validate a modified Thrombolysis In Myocardial Infarction (TIMI) risk score that classifies patients with either ST-segment deviation or cardiac troponin elevation as high risk. The objectives were to determine the ability of the modified score to risk-stratify emergency department (ED) patients with chest pain and to identify patients safe for early discharge. METHODS: This was a prospective cohort study in an urban academic ED over a 9-month period...

STUDY OBJECTIVE: The Thrombolysis in Myocardial Infarction (TIMI) risk score is a 7-item tool derived from trials of patients with unstable angina/non-ST segment elevation myocardial infarction for risk stratification with respect to outcomes. It has been retrospectively evaluated in emergency department (ED) patients with potential acute coronary syndrome but has not been prospectively validated in this patient population. To validate the use of the TIMI risk score in the ED, we prospectively assess its potential utility in a broad ED chest pain patient population...

AIMS: Regarding prognosis, patients with a non-ST elevation acute coronary syndrome (ACS) are a very heterogeneous population, with varying risks of early and long-term adverse events. Early risk stratification at admission seems to be essential for a tailored therapeutic strategy. We sought to compare the prognostic value of three ACS risk scores (RSs) and their ability to predict benefit from myocardial revascularization performed during initial hospitalization. METHODS AND RESULTS: We studied 460 consecutive patients admitted to our coronary care unit with an ACS [age: 63+/-11 years, 21...
