Acute Decompensated Heart Failure Management

Immediate Management Priorities

The European Society of Cardiology recommends initiating oxygen therapy immediately with target saturation >94% to address hypoxemia from pulmonary edema 1
The European Society of Cardiology suggests considering non-invasive ventilation (CPAP or NIPPV) promptly if respiratory distress is present, as coarse gurgly lung sounds and dyspnea suggest significant pulmonary congestion 2, 1
Prepare for endotracheal intubation and invasive ventilation if the patient develops respiratory failure with hypoxemia, hypercapnia, acidosis, physical exhaustion, or diminished consciousness 2

The European Society of Cardiology recommends administering intravenous furosemide immediately as the first-line diuretic for volume overload 1
The European Society of Cardiology suggests giving sublingual or intravenous nitrates titrated to blood pressure to reduce preload and afterload 1
Consider morphine for dyspnea relief, though use caution as opiates can depress respiration and should be monitored frequently 2

Target systolic blood pressure between 100-120 mmHg and heart rate <60 beats/min in the absence of neurological complications 3, 4
If blood pressure control is needed, use intravenous beta-blockers, nitrates, sodium nitroprusside, or calcium channel blockers, with beta-blockers started before other antihypertensive agents 3, 4

The European Society of Cardiology recommends point-of-care troponin testing should be performed urgently to assess for concurrent myocardial infarction 5
Echocardiography is mandatory to assess valve function, ventricular function, and exclude mechanical complications 2, 5

Transfer immediately to a facility with intensive cardiac care unit capability for hemodynamic monitoring and advanced heart failure management 3, 4
Ensure 24/7 echocardiography availability to assess ventricular function, valve function, and exclude mechanical complications 2, 5

Use GRACE Risk Score for risk stratification if ACS is confirmed, as it is superior to subjective physician assessment 6
If cardiogenic shock develops, this carries high mortality and requires immediate invasive strategy with consideration of mechanical circulatory support 6

Do not delay diuretics and vasodilators while awaiting diagnostic confirmation; the clinical presentation of dyspnea, diaphoresis, and bilateral pulmonary opacities warrants immediate treatment 2, 1
Do not assume LBBB is chronic without comparison to prior ECGs; new LBBB with chest pain is a STEMI equivalent requiring urgent catheterization 6
Do not administer antithrombotic therapy until aortic dissection is excluded, particularly given the chest pressure and valve history 3, 4

Chest radiography is a first‑line diagnostic tool for acute heart failure, showing pulmonary edema with an approximate sensitivity of 57 % and specificity of 89 %【7】.

Measurement of natriuretic peptides (BNP or NT‑proBNP) is advised for every patient in whom acute heart failure is suspected, as it supports diagnosis and guides management【8】.

Pneumonia typically presents with fever, a productive cough, and localized lung findings, which helps distinguish it from the bilateral coarse crackles characteristic of cardiogenic pulmonary edema【9】.
