What is the initial treatment for acute decompensated heart failure (ADHF) with tachycardia?

From the Guidelines

The initial treatment for acute decompensated heart failure (ADHF) with tachycardia should focus on stabilizing the patient through several key interventions, including intravenous loop diuretics, supplemental oxygen, and addressing the underlying cause of tachycardia, with rate control using beta-blockers or calcium channel blockers if atrial fibrillation is present, as recommended by the most recent guidelines 1.

Key Interventions

• Intravenous loop diuretics, such as furosemide, should be administered promptly to reduce fluid overload.
• Supplemental oxygen should be provided to maintain oxygen saturation above 92%.
• For tachycardia specifically, the underlying cause must be addressed - if it's a compensatory response to heart failure, treating the heart failure will help normalize the heart rate.
• If atrial fibrillation is present, rate control with beta-blockers (such as metoprolol) or calcium channel blockers (such as diltiazem or verapamil) may be appropriate, though these should be used cautiously in decompensated patients, as recommended by the 2024 ESC guidelines for the management of atrial fibrillation 1.

Rate Control

• Beta-blockers, diltiazem, verapamil, or digoxin are recommended as first-choice drugs in patients with AF and LVEF >40% to control heart rate and reduce symptoms, as stated in the 2024 ESC guidelines 1.
• Beta-blockers and/or digoxin are recommended in patients with AF and LVEF ≤40% to control heart rate and reduce symptoms, as stated in the 2024 ESC guidelines 1.

Additional Considerations

• Vasodilators like nitroglycerin can reduce preload and afterload, especially in patients with hypertension.
• Continuous monitoring of vital signs, urine output, and respiratory status is essential during initial treatment to guide therapy adjustments and prevent complications.
• The 2014 AHA/ACC/HRS guideline for the management of patients with atrial fibrillation also recommends control of resting heart rate using either a beta blocker or nondihydropyridine calcium channel antagonist in patients with persistent or permanent AF and compensated HF with preserved ejection fraction (HFpEF) 1.

From the Research

Initial Treatment for Acute Decompensated Heart Failure with Tachycardia

The initial treatment for acute decompensated heart failure (ADHF) with tachycardia involves several key strategies:

• Stabilizing hemodynamic status 2
• Relieving congestion through intravenous loop diuretics 3
• Instituting afterload reduction with vasodilators in normotensive or hypertensive heart failure 3
• Considering the use of beta-blockers to control heart rate, although their benefit on survival may be lower in patients with heart failure with reduced ejection fraction when atrial fibrillation is present 4

Management of Tachycardia in ADHF

In patients with ADHF and tachycardia, the management of tachycardia is crucial:

• Adequate ventricular rate control is usually a resting rate of less than 100 beats per minute, but lower resting rates may be appropriate 4
• Treatment with a beta-blocker is almost always required to achieve rate control in patients with atrial fibrillation and heart failure 4
• Digoxin may be useful in the presence of hypotension or an absolute contraindication to beta-blocker treatment, but it does not improve survival 4

Additional Therapeutic Considerations

Additional therapeutic considerations in the management of ADHF with tachycardia include:

• The use of inotropic drugs or mechanical circulatory support in patients with severe circulatory failure 2
• The consideration of ultrafiltration in cases where diuretics are not effective 3
• The role of non-invasive ventilation devices for the stabilization and treatment of ADHF 5
