What are the symptoms, classification, and treatment options for Congestive Cardiac Failure (CCF)?

Symptoms, Classification, and Treatment of Congestive Cardiac Failure (CCF)

Congestive Cardiac Failure (CCF) requires a structured approach to management including pharmacological therapy with ACE inhibitors, beta-blockers, diuretics, and SGLT2 inhibitors, along with lifestyle modifications to reduce mortality and improve quality of life. 1

Symptoms of CCF

Common Symptoms

• Dyspnea (exertional breathlessness)
• Fatigue
• Pulmonary congestion/edema
• Peripheral edema
• Rapid weight gain (due to fluid retention)
• Reduced exercise tolerance 2

Additional Symptoms

• Orthopnea (breathlessness when lying flat)
• Paroxysmal nocturnal dyspnea
• Nocturnal cough
• Reduced appetite
• Confusion (especially in elderly)
• Palpitations (due to arrhythmias) 2

Classification of Heart Failure

New York Heart Association (NYHA) Functional Classification

• Class I: No limitation of physical activity; ordinary activity does not cause symptoms
• Class II: Slight limitation of physical activity; comfortable at rest, but ordinary activity results in symptoms
• Class III: Marked limitation of physical activity; comfortable at rest, but less than ordinary activity causes symptoms
• Class IV: Unable to carry out any physical activity without discomfort; symptoms present at rest 2

Based on Ejection Fraction

• HFrEF: Heart Failure with reduced Ejection Fraction (EF <40%)
• HFmrEF: Heart Failure with mid-range Ejection Fraction (EF 40-49%)
• HFpEF: Heart Failure with preserved Ejection Fraction (EF ≥50%) 1

Based on Progression

• Stage A: At high risk for HF but without structural heart disease or symptoms
• Stage B: Structural heart disease but without signs or symptoms of HF
• Stage C: Structural heart disease with previous or current symptoms of HF
• Stage D: Refractory HF requiring specialized interventions 1

Treatment of CCF

Pharmacological Therapy

First-Line Medications

1. ACE Inhibitors (for patients with reduced EF)

   • First-line therapy for patients with LVEF <40-45%
   • Examples: Lisinopril (2.5-5 mg → 20-40 mg daily), Enalapril (2.5 mg → 10-20 mg twice daily)
   • Should be uptitrated to target doses shown effective in clinical trials 2, 1

2. Beta-Blockers

   • Examples: Bisoprolol (1.25 mg → 10 mg daily), Carvedilol (3.125 mg → 25-50 mg twice daily)
   • Start at low dose and gradually uptitrate 1

3. SGLT2 Inhibitors

   • Recommended regardless of diabetes status
   • Examples: Dapagliflozin or Empagliflozin 10 mg daily
   • Can be initiated early in treatment 1

4. Mineralocorticoid Receptor Antagonists (MRAs)

   • Examples: Spironolactone (12.5-25 mg → 25-50 mg daily), Eplerenone (25 mg → 50 mg daily)
   • Particularly for NYHA class II-IV with LVEF ≤35% 1

Additional Medications

• Diuretics: Essential for symptomatic treatment when fluid overload is present

  • Loop diuretics (e.g., furosemide) or thiazides
  • Should be administered with ACE inhibitors when possible 2

• Angiotensin Receptor-Neprilysin Inhibitor (ARNi)

  • Sacubitril/valsartan (49/51 mg → 97/103 mg twice daily)
  • First choice for patients with NYHA class II-III symptoms 1

• Angiotensin Receptor Blockers (ARBs)

  • Alternative if ACE inhibitors not tolerated (due to cough or angioedema)
  • Example: Candesartan (4-8 mg → 32 mg daily) 1

• Digoxin: Added to improve clinical symptoms, especially in patients with atrial fibrillation 3

Non-Pharmacological Management

Lifestyle Modifications

1. Sodium Restriction

   • Control sodium intake, especially in severe heart failure
   • Moderate restriction is better than strict reduction 4

2. Fluid Management

   • Fluid restriction of 1.5-2 L/day advised in advanced heart failure
   • Self-monitoring of weight (sudden gain >2 kg in 3 days requires attention) 2

3. Exercise

   • Regular physical activity recommended for stable patients
   • Exercise training programs beneficial for NYHA class II-III
   • Start with low-intensity exercise and gradually increase 2, 1

4. Alcohol Limitation

   • Moderate intake (1-2 glasses of wine/day) permitted
   • Complete abstinence recommended in alcohol-induced cardiomyopathy 2

5. Smoking Cessation

   • Strongly recommended for all patients 2, 1

Device Therapy and Surgical Options

• Implantable Cardioverter Defibrillator (ICD): For patients with LVEF ≤35% and NYHA Class II-III symptoms 1
• Cardiac Resynchronization Therapy (CRT): For patients with LVEF ≤35%, QRS ≥150ms, and left bundle branch block 1
• Revascularization: Catheter interventions or surgery when appropriate 2
• Heart Transplantation: For end-stage disease 1
• Mechanical Circulatory Support: For advanced heart failure 1

Patient Education and Monitoring

Essential Education Topics

• Explanation of heart failure and symptom recognition
• Self-monitoring (daily weight, symptoms)
• Medication adherence
• Diet and fluid recommendations
• Exercise guidelines
• When to contact healthcare providers 2

Monitoring

• Regular assessment of electrolytes and renal function (1-2 weeks after medication initiation or dose changes)
• Blood pressure and heart rate monitoring
• Adjustment of diuretics according to volume status 1

Common Pitfalls and Caveats

1. Medication Avoidance: The following should be used with caution or avoided:

   • NSAIDs and COX-2 inhibitors
   • Class I antiarrhythmics
   • Calcium channel blockers (verapamil, diltiazem)
   • Tricyclic antidepressants
   • Corticosteroids 2

2. Precipitating Factors for exacerbation:

   • Non-compliance with salt restriction (22%)
   • Pulmonary infections (common non-cardiac cause)
   • Inappropriate medication adjustments
   • Arrhythmias 5

3. Medication Titration: Start with low doses and gradually increase to target doses, monitoring for side effects 1

4. Prognostic Factors: Poor prognosis associated with:

   • Low LVEF
   • Higher NYHA class
   • Elevated urea/creatinine
   • Hyponatremia
   • Limited exercise capacity 6
