Dr. Eric Letovsky and Dr. Brian Steinhart describe a practical way to approach patients with undifferentiated SOB and acute congestive heart failure, the utility of various symptoms and signs in the diagnosis of CHF, as well as the controversies surrounding the best use of BNP and Troponin in the ED. A discussion of the use of ultrasound for patients with SOB as well as the indications for formal Echo are reviewed. In the second part of the episode they discuss the management of acute congestive heart failure based on a practical EM model, as well as the difficulties surrounding disposition of patients with CHF.
