Management of Acute Decompensated Heart Failure Due to Volume Overload

Initial Management

• The American Heart Association recommends administering oxygen therapy in patients with SpO2 <90% to improve oxygenation 3
• The European Society of Cardiology suggests considering non-invasive ventilation (NIV) in patients with respiratory distress to decrease work of breathing and reduce the need for endotracheal intubation 4, 3
• The American College of Cardiology recommends administering intravenous loop diuretics promptly to reduce congestion 1, 2
• For diuretic-naïve patients, the European Journal of Heart Failure suggests a furosemide 20-40 mg IV bolus 5, 3
• The American Heart Association recommends monitoring urine output, vital signs, daily weight, and clinical signs of congestion to guide therapy 1, 2

Diuretic Intensification for Inadequate Response

• The American College of Cardiology recommends intensifying the diuretic regimen by increasing the dose of IV furosemide, switching from bolus to continuous infusion, or adding a second diuretic agent 1, 2, 5
• The European Journal of Heart Failure suggests adding a thiazide diuretic (hydrochlorothiazide 25 mg PO) for combination diuretic therapy 5

Adjunctive Therapies

• The American College of Cardiology recommends considering IV vasodilators (nitroglycerin, nitroprusside, or nesiritide) as adjuncts to diuretic therapy to improve symptoms 1, 2, 5
• The European Heart Journal suggests using sublingual nitrates as an alternative 3

Monitoring and Precautions

• The American Heart Association recommends monitoring daily serum electrolytes, urea nitrogen, and creatinine during IV diuretic use 1, 2
• The European Journal of Heart Failure suggests watching for potential adverse effects of loop diuretics, including electrolyte abnormalities, hypovolaemia, and dehydration 5

Discharge Planning

• The American College of Cardiology recommends addressing optimization of chronic oral HF therapy, assessment of volume status and blood pressure, monitoring of renal function and electrolytes, management of comorbid conditions, and heart failure education before hospital discharge 1, 2
• The American Heart Association suggests scheduling a follow-up visit within 7-14 days and telephone follow-up within 3 days of discharge 1
