Acute Decompensated Heart Failure Management

Hospitalization Criteria

The European Society of Cardiology (ESC) guidelines define clear criteria for hospital admission in acute heart failure, which this patient meets, including persistent significant dyspnea, hypoxemia with SpO2 <90%, new or worsening bilateral leg edema, and massive ascites and pleural effusion 1, 2, 3
The patient has increasing dyspnea, hypoxemia, bilateral leg edema, massive ascites, and pleural effusion, indicating acute decompensated heart failure, possibly overlaid with a COPD exacerbation 1, 2, 3

The ESC guidelines recommend ICU admission for high-risk patients with persistent significant dyspnea, hemodynamic instability, and multiple comorbidities 1, 2, 3
The patient requires continuous pulse oximetry and arterial/venous blood gas analysis with pH, PaCO2, and lactate, especially with COPD and respiratory problems 1, 2, 3

Blood gas analysis is required immediately, and non-invasive ventilation (NIV) is indicated for pH <7.35 with hypercapnia 1, 2, 3, 4
Oxygen therapy is indicated for SpO2 <90% or PaO2 <60 mmHg, with controlled oxygen administration to avoid hypercapnia in COPD patients 1, 2, 3
NIV should be considered for respiratory rate >25/min and SpO2 <90%, reducing the need for endotracheal intubation 1, 2, 3

Acute decompensated heart failure is likely, with bilateral leg edema, ascites, and pleural effusion indicating severe volume overload 1, 5, 6
COPD exacerbation is a contributing factor, with increasing dyspnea and potential need for bronchodilators and systemic corticosteroids 4, 7, 8
Pulmonary embolism must be excluded, with immobility, obesity, and heart failure as risk factors 1, 3

Delayed admission is dangerous, with increased mortality in high-risk patients 1, 2
Caution is required with diuretic therapy, especially in patients with ascites and liver involvement, with monitoring for electrolyte disturbances and worsening renal function 6

In patients receiving aggressive intravenous diuretics, the development of worsening renal function is linked to an approximately three‑fold increase in in‑hospital mortality, highlighting the need for close renal monitoring during decongestion therapy. 9
