Reed MJ et al. The ROSE (Risk Stratification of Syncope in the Emergency Department) study. J Am Coll Cardiol. DOI: 10.1016/j.jacc.2009.09.049. PMID: 20170806. Figure 2: any one of BNP ≥300 pg/mL, heart rate ≤50/min, fecal occult blood when gastrointestinal bleeding is suspected, hemoglobin ≤90 g/L, chest pain with syncope, an ECG Q wave not in lead III, or room-air saturation ≤94% is high risk. Validation sensitivity 87.2%, specificity 65.5%, negative predictive value 98.5%. (2010)
