What is the best management approach for an elderly adult patient with a history of cardiovascular disease, presenting with heart failure, ascites, bipedal edema, and pleural effusion?

Management of Heart Failure with Severe Volume Overload

Initiate aggressive intravenous loop diuretics immediately without delay, as early intervention in the emergency department or outpatient clinic is associated with better outcomes for patients hospitalized with decompensated heart failure. 1

Immediate Assessment and Stabilization

Initial Clinical Evaluation

• Assess adequacy of systemic perfusion by checking mental status, skin perfusion, urine output, and blood pressure to determine if the patient is "warm" (adequate perfusion) or "cold" (hypoperfused) 1
• Determine volume status by examining jugular venous pressure, peripheral edema extent (bipedal edema), presence of ascites, and pleural effusion on chest radiograph 1
• Identify precipitating factors including acute coronary syndromes, severe hypertension, arrhythmias, infections, pulmonary emboli, renal failure, or medication/dietary noncompliance 1
• Obtain chest radiograph, electrocardiogram, and echocardiography as key diagnostic tests 1
• Measure BNP or NT-proBNP in patients where the contribution of heart failure is uncertain, interpreting results in context of all clinical data 1
• Administer oxygen therapy if SpO2 is below 95% to relieve hypoxemia-related symptoms 1, 2

Acute Coronary Syndrome Exclusion

• Obtain electrocardiogram and cardiac troponin testing immediately to identify or exclude acute coronary syndrome as a precipitant 1

Primary Treatment Strategy: Aggressive Diuresis

Initial Diuretic Therapy

• Administer intravenous loop diuretics immediately upon presentation in the emergency department without waiting for admission 1
• If already on loop diuretics, the initial IV dose should equal or exceed the chronic oral daily dose 1
• Monitor urine output and signs of congestion serially, titrating diuretic dose accordingly to relieve symptoms and reduce extracellular fluid volume excess 1

Monitoring During Diuresis

• Measure fluid intake and output carefully along with vital signs and daily body weight at the same time each day 1
• Check daily serum electrolytes, urea nitrogen, and creatinine during IV diuretic use or active medication titration 1
• Assess clinical signs of perfusion and congestion in both supine and standing positions 1
• Measure diuresis and natriuresis shortly after the first diuretic bolus to detect poor diuretic response requiring dose augmentation 2

Escalation for Inadequate Diuresis

When diuresis is inadequate to relieve congestion, intensify the diuretic regimen using one of three strategies: 1

• Higher doses of loop diuretics (double or triple the initial dose)
• Addition of a second diuretic such as metolazone, spironolactone, or intravenous chlorothiazide for sequential nephron blockade 1
• Continuous infusion of a loop diuretic rather than intermittent boluses 1

Adjunctive Vasodilator Therapy

In patients with severely symptomatic fluid overload WITHOUT systemic hypotension, add vasodilators such as intravenous nitroglycerin, nitroprusside, or nesiritide to diuretics, particularly in those who do not respond to diuretics alone. 1

This is especially beneficial for the acute cardiogenic pulmonary edema phenotype with marked blood pressure elevation 2

Management of Hypotension with Fluid Overload

In patients with clinical hypotension associated with hypoperfusion AND obvious elevated cardiac filling pressures (elevated JVP, elevated pulmonary artery wedge pressure), administer intravenous inotropic or vasopressor drugs to maintain systemic perfusion and preserve end-organ performance. 1

Inotrope Selection

• Dopamine, dobutamine, or milrinone may be reasonable for documented severe systolic dysfunction with low blood pressure and low cardiac output 1
• Avoid parenteral inotropes in normotensive patients without evidence of decreased organ perfusion 1

Invasive Hemodynamic Monitoring Indications

Perform invasive hemodynamic monitoring in patients who: 1

• Are in respiratory distress or have impaired perfusion where adequacy of intracardiac filling pressures cannot be determined clinically 1
• Have persistent symptoms despite empiric therapy adjustment with uncertain fluid status, perfusion, or vascular resistance 1
• Have systolic pressure remaining low or symptomatic despite initial therapy 1
• Have worsening renal function with therapy 1
• Require parenteral vasoactive agents 1

Do NOT routinely use invasive monitoring in normotensive patients with symptomatic response to diuretics and vasodilators. 1

Refractory Congestion Management

Ultrafiltration is reasonable for patients with refractory congestion not responding to medical therapy. 1

Guideline-Directed Medical Therapy

Continuation of Existing Therapy

In patients with reduced ejection fraction on chronic ACEIs/ARBs and beta-blockers, continue these therapies during hospitalization in the absence of hemodynamic instability or contraindications. 1

Initiation Before Discharge

In patients with reduced ejection fraction NOT on ACEIs/ARBs and beta-blockers, initiate these therapies in stable patients prior to hospital discharge. 1

Initiate beta-blocker therapy only after: 1

• Optimization of volume status
• Successful discontinuation of IV diuretics, vasodilators, and inotropic agents
• Patient is stable
• Start at low dose with particular caution

Fluid and Sodium Restriction

Sodium Restriction (Primary Strategy)

Limit dietary sodium to ≤2 g daily as the primary strategy for reducing fluid retention, which has stronger evidence than fluid restriction alone. 3

Fluid Restriction (Selective Use)

Limit fluid intake to approximately 2 L/day for: 3

• Most hospitalized patients who are not diuretic-resistant or significantly hyponatremic
• Patients with persistent fluid overload despite optimal medical therapy and sodium restriction

Consider stricter fluid restriction (1.5-2 L/day) for: 3

• Patients with hyponatremia (serum sodium <134 mEq/L)
• Diuretic-resistant patients when combined with sequential nephron blockade
• Patients with severe symptoms and persistent congestion

Critical Discharge Criteria

Do NOT discharge patients until: 3

• Euvolemia (dry weight) is achieved - unresolved edema attenuates diuretic response and increases readmission risk 3
• A stable and effective diuretic regimen is established 3
• Transition from IV to oral diuretics is complete with careful attention to dosing and electrolyte monitoring 1

Discharge Planning

Provide comprehensive written discharge instructions emphasizing: 1

• Diet (sodium restriction ≤2 g daily)
• Discharge medications with focus on adherence and uptitration to recommended doses of ACEI/ARB and beta-blocker
• Activity level
• Follow-up appointments
• Daily weight monitoring (recognize rapid weight gain >2 kg in 3 days)
• What to do if heart failure symptoms worsen

Utilize post-discharge systems of care to facilitate transition to effective outpatient care. 1

Common Pitfalls to Avoid

• Do not reduce diuretic intensity for small or moderate elevations in BUN and creatinine if renal function stabilizes 3
• Avoid overly aggressive fluid restriction which may lead to increased thirst, reduced quality of life, and risk of heat stroke 3
• Do not discharge before achieving euvolemia as this significantly increases readmission risk 3
• Ensure medication reconciliation on both admission and discharge 1
