Initial Management of Acute Decompensated Heart Failure with Reduced Ejection Fraction

Immediate Management Priorities

The American College of Cardiology recommends non-invasive ventilation and IV furosemide for patients presenting with acute decompensated heart failure, exertional dyspnea, orthopnea, and reduced ejection fraction 1
Intravenous loop diuretics should be started without delay in the emergency department or outpatient clinic, as early intervention is associated with better outcomes in patients hospitalized with decompensated heart failure 1
The initial IV dose should equal or exceed the patient's chronic oral daily dose if already on diuretics, or start with an appropriate IV dose if diuretic-naive 1

Patients with significant fluid overload require intravenous loop diuretics as first-line therapy 1
Urine output and signs of congestion should be serially assessed, with diuretic dose titrated accordingly to relieve symptoms and reduce extracellular fluid volume excess 1
If diuresis is inadequate, intensify the regimen using higher loop diuretic doses, addition of a second diuretic, or continuous infusion of loop diuretics 1

Invasive hemodynamic monitoring or respiratory support should be performed in patients with respiratory distress or impaired perfusion when adequacy of intracardiac filling pressures cannot be determined from clinical assessment 1
Non-invasive ventilation can provide immediate respiratory support while IV diuretics work to reduce pulmonary congestion 1

During IV diuretic therapy, monitor fluid intake and output measurements, vital signs, body weight, clinical signs and symptoms of systemic perfusion and congestion, and daily serum electrolytes, urea nitrogen, and creatinine concentrations 1

In patients with reduced ejection fraction experiencing symptomatic exacerbation requiring hospitalization, continue chronic maintenance treatment with ACE inhibitors/ARBs and beta-blockers in the absence of hemodynamic instability or contraindications 1

Never delay diuretic initiation waiting for admission to the hospital floor—start in the emergency department immediately 1
Do not give IV fluids to patients with clear signs of volume overload (orthopnea, dyspnea) 1
Monitor for worsening renal function and electrolyte abnormalities, particularly hypokalemia and hypomagnesemia 1
