Acute Heart Failure.

Heart failure impacts millions of Americans and has an approximate 5-year mortality rate of 50%-55%. Decompensation of this disease state could result in a patient's initial presentation and diagnosis or may reflect a worsening of a chronic condition that is being managed but needs optimization. Secondary to this, it is important for members of the health care team in the emergency department to recognize the presentation of this disease and manage the patient's signs and symptoms appropriately. Patients may be normotensive upon presentation or hemodynamically unstable. Those who are normotensive are often managed with loop diuretics and possibly low-dose vasodilators, whereas those who are hemodynamically unstable require more aggressive, focused care. It is important to note that some patients may present with respiratory failure and with no known history of heart failure. In these cases, a rapid and accurate diagnosis is critical. This article briefly summarizes the common acute clinical presentations of heart failure and the therapies considered first line for treatment based on the primary literature.
