Acute Decompensated Heart Failure with Volume Overload

Patient Assessment and Management

• The European Society of Cardiology recommends that patients with acute heart failure should receive IV loop diuretics in the emergency department, with urine output and symptoms monitored serially to titrate the dose 1, 2
• The American College of Cardiology suggests that IV loop diuretic dose should be equivalent to or higher than the chronic oral daily dose 2
• Patients with end-stage renal disease (ESRD) and congestive heart failure (CHF) are at high risk of volume overload, and furosemide 40mg stat may be inadequate 1, 2
• The European Heart Journal notes that anemia can exacerbate shortness of breath (SOB) in patients with CHF and ESRD, particularly if erythropoietin deficiency is present 3, 4
• Metabolic acidosis can occur in patients with ESRD, leading to compensatory tachypnea 1
• Pulmonary embolism is a potential cause of SOB in patients with ESRD and CHF, although the absence of chest pain and a high SPO2 make it less likely 1, 3
• The American College of Cardiology recommends daily monitoring of weight, intake/output, electrolytes, and clinical signs of congestion in patients with acute decompensated heart failure 2
• Infection workup, including urine culture and blood cultures, should be performed promptly in patients with suspected sepsis 1, 3
• A chest X-ray should be performed to evaluate for pulmonary congestion, pleural effusion, and cardiomegaly 1
• Psychogenic SOB should not be diagnosed until organic causes have been ruled out, as it can be a sign of underlying cardiac or renal disease 1, 2
• Furosemide PRN regimen may be inadequate for patients with CHF, and scheduled dosing may be necessary 2
• The combination of ACE inhibitor and furosemide can worsen renal function, and creatinine should be monitored closely 5
• Constipation and flatulence can be signs of gut congestion, which may indicate right-sided heart failure 1

Acute Decompensated Heart Failure Management

Immediate Management Priorities

• The European Society of Cardiology recommends immediate IV loop diuretics combined with vasodilators, supplemental oxygen or non-invasive ventilation, and urgent evaluation for acute coronary syndrome given the left shoulder pain 6, 7, 8
• Initiate non-invasive positive pressure ventilation (CPAP or BiPAP) immediately for the pulmonary edema evidenced by B-lines on ultrasound, which improves oxygenation and reduces work of breathing while medical therapy takes effect 7, 8
• Invasive ventilation with endotracheal intubation should be reserved for patients who fail non-invasive ventilation 7, 8

Pharmacologic Therapy

• Primary treatment consists of vasodilation plus diuretics, with vasodilators being the primary therapy for left-heart backward failure with elevated blood pressure 6, 7, 8
• Add bronchodilators if wheezing ("cardiac asthma") is present 7, 8
• Narcotics (morphine) may be considered for severe dyspnea and anxiety, though use cautiously 7, 8

Critical Diagnostic Consideration

• Acute myocardial ischemia or infarction is a frequent cause of left-heart backward failure and requires specific intervention 7, 8
• The combination of chest/shoulder pain with acute decompensation should prompt consideration of urgent cardiac catheterization if ACS is confirmed 8

Hemodynamic Profile Considerations

• For a "warm and wet" profile (adequate perfusion but volume overloaded), vasodilators and diuretics are appropriate; inotropes are NOT indicated 6, 7

Important Caveats

• Do not use inotropes in this hypertensive patient—they are indicated only for forward failure with low cardiac output and hypotension 6, 7
• Do not give excessive fluids—this patient has backward failure with pulmonary edema 6, 7
• The left shoulder pain must not be dismissed—it may represent referred cardiac pain from ischemia 8
