Study Notes
Acute Decompensated Heart Failure (ADHF)
- ADHF involves new or worsening heart failure symptoms, often due to volume overload, hypoperfusion, or both, leading to emergency visits or hospitalizations.
- Other names for ADHF include acute heart failure, acute heart failure syndrome, and cardiogenic pulmonary edema.
Etiology and Hospitalization
- Hospital admissions for ADHF have increased threefold in the past 30 years.
- 70% of cases arise from exacerbations of existing heart failure due to poor adherence, inadequate medication regimens, dietary indiscretions, or infections.
- 25% of cases are de novo, resulting from myocardial infarction (MI), arrhythmias, or sudden increases in blood pressure.
Precipitating Factors
- Precipitating factors include medications, dietary non-compliance, arrhythmias, uncontrolled hypertension, myocardial ischemia/infarction, anemia, endocrine abnormalities, infections, pulmonary emboli, and substance abuse.
Medication Effects
- Medications can worsen heart failure by promoting fluid retention, poor adherence, or recent initiation or dosage increases of beta-blockers.
- Certain drugs like NSAIDs, glitazones, and glucocorticoids promote fluid retention, while non-DHP CCBs and some other medications have negative inotropic effects or exhibit cardiotoxicity.
Clinical Presentation
- "Wet" ADHF indicates fluid overload with symptoms like peripheral edema, JVD, dyspnea, and increased creatinine/blood urea nitrogen (BUN).
- "Cold" ADHF presents with signs of poor perfusion such as cool extremities, hypotension, altered mental status, and worsening renal or hepatic function.
Hemodynamic Assessment
- Markers of hemodynamic stress include B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP), released in response to ventricular wall stress.
- ADHF can be confirmed by BNP >100 pg/mL or NT-proBNP >300 pg/mL. Increased levels can result from conditions like pulmonary emboli and renal dysfunction.
Laboratory and Monitoring Requirements
- Routine labs include BMP, liver function tests, oxygen saturation, and serum lactate.
- Careful monitoring encompasses volume status, oxygenation, weight, blood pressure, kidney function, and electrolytes during diuretic therapy.
Treatment Goals
- Goals for managing ADHF include symptom relief and lowering pulmonary capillary wedge pressure (PCWP) without compromising cardiac output.
- Loop diuretics are first-line therapy for volume overload; doses should be escalated accurately based on home regimen.
Diuretic Resistance and Strategies
- Diuretic resistance occurs due to compensatory sodium reabsorption. Management involves increasing doses, adding thiazide-type diuretics, or switching to continuous infusion.
IV Vasodilators
- IV vasodilators may be considered for managing refractory volume overload, acute pulmonary edema, and severe hypertension.
- Preferred IV vasodilators include nitroglycerin for preload reduction and sodium nitroprusside for balanced dual arterial and venous dilation, both requiring careful monitoring.
Non-Pharmacological Interventions
- Ultrafiltering fluid is effective for diuretic-resistant patients or those with renal impairment despite medical treatments.
Hyponatremia in HF
- ADHF is commonly associated with hypervolemic hyponatremia and treatment options include fluid restriction, diuretics, hypertonic saline, and vasopressin antagonists to correct sodium levels.
