The prognosis of myocardial infarction in patients with rapid atrial fibrillation (RAF) is poorly known. We sought to ascertain if troponin concentrations are associated with a higher risk of major adverse cardiovascular events (MACE) in patients with RAF and chest discomfort suggestive of coronary origin. ⋯ In patients with RAF who complain of chest pain, increased troponin levels are related to adverse cardiovascular outcomes.

We investigated if the phenotypic classification of acute heart failure (AHF) based on the number of signs/symptoms of congestion and hypoperfusion at emergency department (ED) arrival identifies subgroups in which intravenous (IV) nitroglycerine (NTG) use improves short-term survival. ⋯ Phenotypical classification of AHF based on congestion/hypoperfusion at ED arrival does not identify subgroups of patients in whom IV-NTG would decrease mortality, although it could potentially be beneficial in those with LVEF of less than 50%. This hypothesis will have to be confirmed in the future. Conversely, our results suggest that IV-NTG may be harmful in patients with only mild clinical congestion.

Observational Study
Early chest CT-scan in emergency patients affected by community-acquired pneumonia is associated with improved diagnosis consistency.
Chest CT-scan (CT) exceeds chest X-ray (CXR) to diagnose community-acquired pneumonia (CAP) but actual use and results remain unclear. We examine whether CT performed at ED visit improved ED diagnosis of CAP as compared to a final diagnosis of CAP at hospital discharge (gold standard diagnosis for the study), and how it impacts relevant clinical outcomes. This retrospective monocenter observational study was based on the analysis of the hospital database. ⋯ In patients admitted after ED, CT improved diagnosis consistency for CAP [88.2% vs. 80.9%; difference 7.3% (95% confidence interval 1.2-13.3%)] with a trend for lower hospital length-of-stay [10.2 vs. 12.2 days; difference -2.0 (95% confidence interval -3.9 to -0.1)], but not ICU admission ( P = 0.09) and in-hospital mortality ( P = 0.056). Diagnosis of patients admitted with CAP improved when CT was obtained at ED visit. These results should be reproduced at a larger scale to test whether early CT conserves healthcare resources.
