Dressler's syndrome, also known as post-myocardial infarction syndrome, is a type of pericarditis, which is inflammation of the pericardium, the protective sac around the heart. This condition typically occurs weeks to months after a heart attack, heart surgery, or injury to the heart or chest. Dressler's syndrome is considered an immune system response to heart damage.

Causes of Dressler's Syndrome

Dressler's syndrome is believed to be caused by an autoimmune response, where the body's immune system mistakenly attacks its own tissues following heart damage. This can occur after:

  1. Heart Attack (Myocardial Infarction): The most common trigger.
  2. Heart Surgery: Especially open-heart procedures.
  3. Traumatic Heart Injury: Such as from a car accident.
  4. Other Cardiac Events: Like percutaneous coronary intervention (angioplasty).

Symptoms of Dressler's Syndrome

The symptoms of Dressler's syndrome can include:

  1. Chest Pain: Often sharp and pleuritic; worsens with deep breaths and improves when sitting up or leaning forward.
  2. Fever
  3. Pericardial Effusion: Fluid accumulation around the heart.
  4. Pleuritic Pain: Pain with breathing.
  5. Shortness of Breath
  6. General Malaise or Fatigue

Treatment of Dressler's Syndrome

The treatment for Dressler's syndrome focuses on reducing inflammation and managing symptoms:

  1. Anti-inflammatory Medications:
    • Aspirin or Nonsteroidal Anti-inflammatory Drugs (NSAIDs): These are first-line treatments for reducing inflammation and relieving pain.
    • Colchicine: Often used in combination with NSAIDs or aspirin, it helps reduce inflammation and prevent recurrences.
    • Corticosteroids: Used in severe cases or when patients do not respond to other treatments. However, they are generally avoided unless absolutely necessary due to potential side effects.

  2. Monitoring: Patients with Dressler's syndrome may need to be monitored for signs of pericardial effusion or cardiac tamponade, which can be complications of the condition.
  3. Treating Complications: If complications like significant pericardial effusion or cardiac tamponade develop, more aggressive treatments such as pericardiocentesis (draining the fluid) may be necessary.
  4. Rest and Gradual Return to Activity: Adequate rest is advised during the acute phase of the condition, followed by a gradual return to normal activities as symptoms improve.

Dressler's syndrome is generally a self-limiting condition and often resolves over time with treatment. However, it can recur, so patients may need long-term follow-up and management. The prognosis is generally good with appropriate treatment.
