Inflammatory Heart Disease

Cardiac Sarcoidosis

Inflammatory Disease Affecting the Heart Causing Rhythm Problems and Heart Failure

Cardiac Sarcoidosis is a condition where clusters of inflammatory cells (granulomas) form in the heart tissue. This can disrupt electrical signals, weaken the heart muscle, and lead to arrhythmias, heart failure, and in advanced cases, the need for a heart transplant.

Arrhythmia + systemic sarcoidosis → Important diagnostic clue

Often underdiagnosed and requires high clinical suspicion.

Understanding

What is Cardiac Sarcoidosis?

In cardiac sarcoidosis:

Inflammatory granulomas form in heart tissue
Electrical pathways may be affected
Heart muscle function may weaken

This leads to:

Arrhythmias (irregular heartbeat)
Conduction blocks
Heart failure

Warning Signs

Early Signs & Symptoms

Palpitations

Early Stage

Dizziness / Syncope

Progressive

Breathlessness

Advanced

Arrhythmia + systemic sarcoidosis → Important diagnostic clue

Risk Factors

Causes & Risk Factors

Cause

Immune-mediated inflammatory disease

Risk Factors

Known sarcoidosis in other organs (lungs, skin)
Middle age
Genetic susceptibility

Progression

Disease Progression

Early Stage Silent/mild involvement

Moderate Stage Conduction abnormalities

Severe Stage Muscle dysfunction

End Stage Transplant needed

Early Stage

Silent or mild involvement

Often undetected

High Suspicion Needed

Moderate Stage

Electrical conduction abnormalities

Device Therapy

Severe Stage

Heart muscle dysfunction

Immunosuppression

End Stage Heart Failure

Severe cardiac damage

Transplant required

Heart Transplant

Testing

Diagnosis & Tests

ECG

Echocardiography

Cardiac MRI

PET scan (for inflammation)

Biopsy (in selected cases)

Evaluate unexplained arrhythmias early

Assess your heart function risk

Management

Treatment Options (Before Transplant)

1. Immunosuppression

Steroids (mainstay)
Other immunosuppressants

2. Arrhythmia Management

Anti-arrhythmic medications

3. Device Therapy

Pacemaker (heart block)
ICD (prevents sudden death)

4. Heart Failure Management

Standard medications

When is Heart Transplant Needed?

Severe heart failure develops

Persistent arrhythmias despite treatment

Progressive disease

Early Treatment Can Control Inflammation

Timely therapy prevents irreversible damage

Important Consideration: Often Underdiagnosed

• May present with sudden arrhythmias • Requires high clinical suspicion • Early diagnosis is critical

Medical/Device Therapy vs Transplant

Medical/Device Therapy

Stage: Early/Moderate • Goal: Control inflammation • Outcome: Good with treatment

Heart Transplant

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