Congestive Heart Failure Exacerbation Management

Aka: Congestive Heart Failure Exacerbation Management, Cardiogenic Shock, Acute Pulmonary Edema Management, Acute Decompensated Congestive Heart Failure, Acute Heart Failure, CHF Exacerbation Management

II. Indications

  1. Acute Pulmonary Edema secondary to CHF exacerbation

III. Epidemiology

  1. Heart Failure exacerbations account for 1 million hospitalizations/year
    1. Account for 80% of all ED based admissions
    2. Account for most of the $40 billion spent on Heart Failure annually
  2. Rehospitalization or death in up to one third of patients within 90 days of Heart Failure hospitalization
    1. As many as 25% of patients are re-admitted in the first month
    2. Medicare penalizes facilities for readmissions within 30 days
    3. Early follow-up after CHF admission is critical (see below)

IV. Pathophysiology

  1. Congestive Heart Failure results in decreased Stroke Volume and Cardiac Output
  2. Decreased renal perfusion results in volume retention
    1. However only 50% of pulmonary edema patients are volume overloaded
  3. Decreased organ perfusion also stimulates other compensatory mechanisms
    1. Norepinephrine release results in increased Blood Pressure and cadiac output
    2. Renin Angiotensin-aldosterone stimulation results in salt retention and increased vascular tone
  4. Redistribution of fluids
    1. Acute blood release from Spleen can rapidly deploy up to 800 ml fluid which may accumulate in the lungs

V. History

  1. See Diastolic Dysfunction
  2. See Systolic Dysfunction

VI. Exam

  1. See Systolic Dysfunction

VII. Labs

  1. Complete Blood Count
    1. Evaluate for Anemia or underlying infection
  2. Comprehensive metabolic panel
    1. Correct Hypokalemia
    2. Consider empiric Magnesium Sulfate (especially if hypokalemic)
      1. Serum Magnesium level does not reflect true intracellular Magnesium depletion
  3. Troponin I
    1. Evaluate differential diagnosis for Acute Coronary Syndrome
    2. Troponin Is increased in many cases of Acute Heart Failure (and in most cases if high sensitivity Troponin Is used)
    3. Persistently elevated Troponin at Day 2 (compared with admission Troponin) is associated with a worse prognosis
  4. B-Type Natriuretic Peptide (BNP or nt-BNP)
    1. Most helpful for its Negative Predictive Value (CHF is less likely with a normal BNP)
    2. Typically over-utilized, and may add little to diagnosis not available with other findings
    3. May be useful when an established “dry” baseline has been set for comparison and for risk stratification
    4. History, Exam and Bedside Ultrasound are often more effective tools in CHF evaluation
    5. Trending does not offer benefit over usual care for inpatient CHF management
      1. Felker (2017) JAMA 318(8): 713-20 +PMID:28829876 [PubMed]

VIII. Diagnostics

  1. See Systolic Dysfunction
  2. Electrocardiogram
  3. Chest XRay
    1. See Chest XRay in Congestive Heart Failure
    2. Normal in 19% of Acute Heart Failure cases
    3. Excludes alternative diagnoses (e.g. Pneumonia)
  4. Bedside Ultrasound or Echocardiogram
    1. See Echocardiogram in CHF
    2. See Bedside Lung Ultrasound in Emergency (Blue Protocol)
    3. See Rapid Ultrasound in Shock (RUSH Exam)
    4. See Inferior Vena Cava Ultrasound for Volume Status
  5. Cardiac Impedance (Impedance Cardiography)
    1. Noninvasive ICU monitoring devices (skin leads) that may be available in some Emergency Departments
    2. Estimates Cardiac Output, Stroke Volume and peripheral vascular resistance
    3. May assist in distinguishing between Preload and Afterload problems, and systolic and Diastolic Dysfunction

IX. Causes: Acute reversible causes of decompensated shock

  1. See Systolic Heart Failure
  2. See Heart Failure Causes
  3. Acute dysrhythmia (e.g. Atrial Fibrillation with rapid ventricular rate)
  4. Acute Myocardial Infarction (or Unstable Angina)
    1. Large anterior Myocardial Infarction (>40% of left ventricle involved)
    2. Right ventricular infarction with right Heart Failure and secondary left Heart Failure
    3. Papillary muscle rupture (with secondary severe valvular insufficiency)
  5. Acute valvular lesion (rare, but potentially catastrophic)
  6. Acute Viral Myocarditis (esp. young patients)
  7. Uncontrolled Hypertension (Hypertensive Crisis)
  8. Hypothyroidism
  9. Excess Intravenous Fluid administration
  10. Non-compliance is most common cause
    1. Noncompliance with chronic CHF medications
    2. Excess dietary Sodium intake
  11. Medications that Exacerbate Heart Failure
    1. NSAIDs
    2. Glitazones
    3. Excess dosing of newly started medication (e.g. Calcium Channel Blocker, Beta Blocker)
  12. High output Heart Failure Causes
    1. Severe Anemia
    2. Hyperthyroidism
    3. Septic Shock

X. Differential Diagnosis: Acute Congestive Heart Failure Exacerbation

  1. See Dyspnea Causes
  2. COPD Exacerbation
    1. Most difficult to distinguish acutely as Dyspnea cause
    2. Initial treatment of both COPD and CHF concurrently if appear equally plausible
      1. Many emergency Dyspnea protocols advocate this approach
  3. Pneumonia
    1. Consider the use of Procalcitonin to exclude Pneumonia when the Chest XRay is non-diagnostic
  4. Acute Coronary Syndrome
  5. Pulmonary Embolism
  6. Pneumothorax
  7. Acute Renal Failure
  8. High Altitude Pulmonary Edema
  9. Medication induced pulmonary edema (Opiates, Naloxone)

XI. Precautions

  1. Cardiogenic pulmonary edema presents most commonly without Fluid Overload
    1. Management focus should be on fluid redistribution, not diuresis
    2. Even those who are Fluid Overloaded (e.g. missed Diuretics, Dialysis) stabilize with fluid redistribution
    3. Fluid redistribution is the key strategy for Acute Heart Failure
      1. Regardless of whether it is due to Systolic Dysfunction or Diastolic Dysfunction
  2. Approach to fluid redistribution
    1. Decrease Preload (Nitroglycerin, BIPAP or CPAP)
    2. Decrease Afterload (ACE Inhibitor)
  3. Identify and specifically treat acute pulmonary edema due to non-Heart Failure cause
    1. Acute Coronary Syndrome
    2. Acute Renal Failure
    3. Arrhythmia (e.g. Atrial Fibrillation with rapid ventricular rate)
    4. Acute valvular catastrophe (presents with new regurgitation murmur)
  4. Rapidly disposition patients with Cardiogenic Shock to an optimal cardiac care setting
    1. Large Myocardial Infarction affecting the left ventricle is the common cause of Cardiogenic Shock
    2. Emergency department is for acute stabilization, but not ideal for definitive Cardiogenic Shock management
    3. Involve early cardiology, cath lab, cardiothoracic surgery, intensivists to expedite disposition
    4. Aspirin and Unfractionated Heparin if suspected underlying Myocardial Infarction
      1. Defer Platelet ADP Receptor Antagonist (e.g. Plavix) to cardiology

XII. Preparations: Preload Reduction

  1. Nitroglycerin (see above)
    1. Most rapid method to reduce Congestive Heart Failure symptoms
      1. Reduces both Afterload and most significantly Preload
      2. Appears safe in acute pulmonary edema and severe Aortic Stenosis, but Exercise caution
        1. Claveau (2015) Ann Emerg Med 66(4):355-62 +PMID:26002298 [PubMed]
    2. High dose (hypertensive Acute Heart Failure)
      1. Clinician should remain at bedside during this phase of administration
      2. Start: 0.4 mg sublingual every 3-5 minutes
      3. Next: High dose Nitroglycerin Drip (50-150 mcg/min) IV
        1. Significantly higher dosing that the typical 0.3 to 0.5 mcg/kg/min (10-25 mcg/min) infusion
        2. Expert opinion recommends starting IV Nitroglycerin at 100-150 mcg/min
      4. Next: Taper to 10-20 mcg/min as Hypoxia and pulmonary edema improve
        1. Titrate in 50 mcg increments every 10-15 minutes
    3. Lower dose (normotensive Acute Heart Failure)
      1. Nitroglycerin Ointment (0.5 to 1 inch)
  2. BIPAP (or CPAP)
    1. Consider starting with higher pressures (e.g. 20/15) with 100% FIO2
    2. Reduces work of breathing and opens alveoli
    3. Increases intrathoracic pressure and decreases venous return
    4. Improves Dyspnea and may avert Endotracheal Intubation
    5. Consider Dexmedetomidine (Precedex) if difficulty tolerating BIPAP or CPAP
      1. Sedative without respiratory depression (similar to Ketamine)
      2. Alpha Adrenergic Central Agonist (similar to Clonidine)

XIII. Preparations: Afterload Reduction

  1. ACE Inhibitor
    1. Enalapril (Enalaprilat, Vasotec) 1.25 mg IV over 5 minutes or Captopril 12.5 to 25 mg sublingual
    2. Single dose for acute Afterload reduction (onset of action within 15 minutes)
    3. Start after the Nitroglycerin is tapered to lower dose (10-20 mcg/min)
    4. No evidence for Angiotensin Receptor Blockers (ARB)
  2. Nicardipine
    1. Offers pure arterial vasodilation, but Hypotension may take some time to resolve after stopping
    2. Clevidipine offers similar activity as Nicardipine with more rapid resolution of Hypotension on stopping
      1. Not widely used due to very high cost, but may be considered once generic
  3. Fenoldopam
    1. Dopamine-1 Agonist (without Dopamine-2 or alpha effects)
    2. Vasodilates peripherally as well as at the Kidney and Spleen (thereby preserving Renal Function)
  4. Nitroglycerin (see above)
    1. Rapid onset of effect, easily titrated, and Hypotension resolves readily on stopping infusion

XIV. Preparations: Furosemide (Lasix) or other Loop Diuretic

  1. Indications
    1. Administered after Preload and Afterload reduction as above, IF Fluid Overloaded
    2. Fewer than 50% of CHF patients have total body Fluid Overload
  2. Option 1: Not on Home Diuretics
    1. Furosemide (Lasix) 40 mg IV (if not on home Diuretic) OR
    2. Furosemide (Lasix) 0.5 to 1.0 mg/kg (40-80 mg) IV
    3. Higher doses may be needed in Chronic Renal Failure
  3. Option 2: On home Diuretics
    1. Calculate hospital Furosemide dose
      1. Total Dose = HOME-DOSE * MULTIPLIER
      2. Where HOME-DOSE is the total daily home dose
      3. Where MULTIPLIER is typically 1.5 (up to 2.5)
      4. Divide the total daily dose over the number of doses per day
    2. Furosemide (Lasix) at 1.5 times the home dose of Loop Diuretic (typical, safer)
      1. Patient taking 40 mg orally daily at home would be given 30 mg IV every 12 hours
    3. Furosemide (Lasix) at 2.5 times the home dose of Loop Diuretic (high dose, caution!)
      1. Patient taking 40 mg orally daily at home would be given 50 mg IV every 12 hours
      2. Exercise caution with higher dose multiplier due to increased risk of Acute Renal Failure
      3. Felker (2011) N Engl J Med 364(9): 797-805 [PubMed]
  4. Option 3: Peacock ED Observation Unit Protocol (see disposition below)
    1. Goal of 1 Liter output during an ED observation
    2. Give Furosemide as single IV bolus of DOUBLE the patient’s daily oral dose (max 180 mg IV)
    3. May repeat as twice the initial IV dose if inadequate urine out at 2 hours
      1. Urine < 0.5 L for Serum Creatinine <2.5 mg/dl OR
      2. Urine <0.25 L for Serum Creatinine >2.5 mg/dl
    4. References
      1. Peacock (2002) Congest Heart Fail 8(2):68-73 [PubMed]
  5. Precautions
    1. Diuretics have a delayed onset of action until Afterload decreases and renal perfusion increases
      1. Diuretics are typically ineffective until other measures (e.g. Bipap, Nitroglycerin) redistribute fluid
      2. Use other agents listed under Preload and Afterload reduction first
      3. Loop Diuretics may not be indicated in all Acute Heart Failure stabilization
    2. Newer recommendations are to use with caution and at lower doses (see precautions above)
      1. Increased risk of Acute Renal Failure, increased hospital stays and increased mortality
    3. Furosemide Continuous Infusion is not recommended
      1. Considered low efficacy compared with bolus dosing and higher risk of complication (e.g. Hypokalemia)
      2. Dosing (listed for historical reference)
        1. Bolus: 40-80 mg IV
        2. Maintainence: 5-40 mg/hour IV infusion

XV. Preparations: Additional Measures for refractory cases

  1. Percutaneous Coronary Intervention
  2. Ultrafiltration, ECMO or Dialysis
    1. Indicated in end-stage renal disease and Fluid Overload
    2. Phlebotomy of 200-300 cc blood may temporize if Dialysis is delayed
      1. Eiser (1997) Clin Nephrol 47(1): 47-9 +PMID: 9021241 [PubMed]
  3. Endotracheal Intubation and Mechanical Ventilation
    1. Decreases work of breathing and provides PEEP
    2. Ensure adequate fluid volume prior to RSI
  4. Intra-aortic balloon pump
    1. Decrease left Ventricular Afterload, wall tension and myocardial oxygen demand
    2. Indications
      1. Primarily indicated in mechanical catastrophe (e.g. ruptured mitral valve)
      2. May also be used to bridge to definitive therapy (e.g. PCI)
  5. Thrombolytics (in STEMI with secondary Cardiogenic Shock)
    1. May be considered in Cardiogenic Shock from STEMI and prolonged transport to PCI (>1.5 hours)
    2. Less effective in left main and proximal LAD lesions, as well as compared with PCI in general

XVI. Preparations: Agents to avoid

  1. Avoid Beta Blockers in acute decompensated Systolic Dysfunction
  2. Avoid Nesiritide (Natrecor)
    1. No longer recommended (previously considered in refractory cases)
  3. Avoid Morphine Sulfate
    1. Poor to no effect on Preload reduction
    2. Associated with increased rates of intubation, ICU length of stay and possibly mortality
  4. Benzodiazepines
    1. Use only with caution
  5. Nitroprusside
    1. Historically started with 0.1 to 0.3 mcg/kg/min IV and titrate up to effect
    2. Falling out of favor due to unpredictable and catastrophic effects on Blood Pressure
  6. Digoxin
    1. Avoid Digoxin in Acute Heart Failure (not effective)

XVII. Management: General

  1. Intravenous lines
    1. Often challenging in CHF exacerbations due to peripheral Vasoconstriction and body habitus (i.e. Obesity)

        2. Much higher dose than typical 0.3 to 0.5 mcg/kg/min (10-25 mcg/min) infusion
        3. Expert opinion recommends starting IV Nitroglycerin at 150 mcg/min
        4. Monitor with automatic Blood Pressure monitor cycling at every 2-5 minutes
      3. Next: Taper to 10-20 mcg/min as Hypoxia and pulmonary edema improve
  4. Step 2: Afterload Reduction
    1. ACE Inhibitor
      1. Enalapril (Enalaprilat, Vasotec) 1.25 mg IV over 5 minutes or
      2. Captopril 12.5 to 25 mg sublingual
