Cardiac Amyloidosis

Protein Deposition in the Heart Leading to Stiff Heart Failure

Cardiac Amyloidosis is a condition where abnormal proteins (amyloid) deposit in the heart muscle, making it stiff and unable to function properly. This leads to progressive heart failure, arrhythmias, and in advanced cases, the need for a heart transplant.

Understanding

What is Cardiac Amyloidosis?

In cardiac amyloidosis:

  • Abnormal proteins deposit in heart tissue
  • Heart walls become stiff (restrictive cardiomyopathy)
  • Filling of heart chambers is impaired

This leads to:

  • Reduced cardiac output
  • Fluid accumulation
  • Progressive heart failure
Classification

Types of Cardiac Amyloidosis

AL (Light Chain) Amyloidosis
  • Related to blood/plasma cell disorders
ATTR Amyloidosis
  • Transthyretin protein-related
  • Hereditary or age-related
Warning Signs

Early Signs & Symptoms

Fatigue
Early Stage
Mild Breathlessness

Risk Factors

Causes & Risk Factors

Causes
  • Protein misfolding disorders
  • Genetic mutations (in ATTR)
Risk Factors
  • Older age (ATTR type)
  • Family history
  • Blood disorders
Progression

Disease Progression

Early Stage Protein deposition
Moderate Stage Heart stiffness
Severe Stage Heart failure
End Stage Transplant needed

Early Stage

Protein deposition begins

Often asymptomatic

Early Detection

Moderate Stage

Heart stiffness increases

Medical Management

Severe Stage

Heart failure develops

Advanced Therapy

End Stage Heart Failure

Severe dysfunction

Transplant required

Heart Transplant
Testing

Diagnosis & Tests

Echocardiography
Cardiac MRI
Blood and urine tests
Biopsy (confirmatory)
Nuclear imaging (for ATTR type)

Evaluate unexplained heart failure early

Assess your heart function risk

Management

Treatment Options (Before Transplant)

1. Targeted Therapy
  • Chemotherapy (AL type)
  • TTR stabilizers (ATTR type)
2. Heart Failure Management
  • Diuretics
  • Symptom control
3. Supportive Care
  • Lifestyle modification
  • Monitoring

When is Heart Transplant Needed?

Advanced heart failure

Poor response to therapy

Severe functional limitation

Early Diagnosis is Crucial

Specialized treatment can slow progression

Important Consideration: Often Misdiagnosed

• Can mimic other heart diseases • Requires specialized testing • Early treatment improves outcomes

Medical Management vs Transplant
Medical Therapy

Stage: Early/Moderate • Goal: Slow progression • Outcome: Improved survival

Heart Transplant

Stage: Advanced • Goal: Replace heart • Outcome: Life-saving
