Dressler’s Syndrome
Dressler’s Syndrome, also known as post-myocardial infarction syndrome, is an inflammatory condition that can occur after a heart attack or cardiac surgery. It is characterized by fever, chest pain, and pericarditis, which is inflammation of the pericardium—the sac surrounding the heart. Although it was first identified in 1956 by Dr. William Dressler, the condition is still not fully understood. This article aims to provide a comprehensive understanding of Dressler’s Syndrome, covering its causes, symptoms, risk factors, diagnosis, and treatment options.
Causes of Dressler’s Syndrome
The exact cause of Dressler’s Syndrome remains unclear, but it is widely believed to be an autoimmune response. Following a heart attack or surgery, damage to the heart tissue can result in the release of cardiac antigens into the bloodstream. In some individuals, the immune system mistakenly identifies these antigens as foreign invaders, triggering an inflammatory response. This response can lead to inflammation of the pericardium and the symptoms associated with Dressler’s Syndrome.

The symptoms of Dressler’s Syndrome can vary in intensity and typically appear weeks to months following a myocardial infarction or cardiac surgery. Recognizing these symptoms is crucial for prompt diagnosis and treatment.
Common Symptoms
- Chest Pain: Often sharp and pleuritic, meaning it worsens with deep breathing or coughing. It may be similar to the pain experienced during a heart attack but is usually not related to ischemia.
- Fever: A persistent, low-grade fever is common in individuals with Dressler’s Syndrome.
- Pericardial Effusion: The accumulation of fluid in the pericardial sac can lead to shortness of breath and discomfort.
- Fatigue: Generalized fatigue and malaise are often reported.
Less Common Symptoms
- Joint Pain: Some individuals may experience arthralgia, which is joint pain without swelling.
- Weight Loss: Unintentional weight loss due to chronic inflammation and decreased appetite.
Risk Factors for Dressler’s Syndrome
Certain factors may increase the likelihood of developing Dressler’s Syndrome. Understanding these risk factors can aid healthcare professionals in identifying individuals who may be at greater risk.
- Recent Cardiac Events: The primary risk factor is a recent myocardial infarction (heart attack) or cardiac surgery, such as coronary artery bypass grafting (CABG) or valve replacement. The risk is higher in cases where there is significant myocardial damage.
- Previous History: Individuals who have had Dressler’s Syndrome in the past are at an increased risk of recurrence, especially following subsequent cardiac events.
- Genetic Predisposition: Although not fully understood, genetic factors may play a role in an individual's susceptibility to autoimmune responses, including those seen in Dressler’s Syndrome.
- Delayed Medical Intervention: Delays in the treatment of a heart attack can lead to more extensive myocardial damage, increasing the risk of developing Dressler’s Syndrome.

Diagnosis of Dressler’s Syndrome
Diagnosing Dressler’s Syndrome requires a careful evaluation of the patient’s medical history, symptoms, and diagnostic tests. It is often a diagnosis of exclusion, meaning other potential causes of the symptoms must be ruled out.
Diagnostic Tests
- Electrocardiogram (ECG): May show changes indicative of pericarditis, such as diffuse ST-segment elevation or PR depression.
- Echocardiogram: Can reveal pericardial effusion and help assess cardiac function.
- Blood Tests: Elevated inflammatory markers, such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), can support the diagnosis.
- Chest X-ray: Used to detect any fluid accumulation around the lungs or heart.
Treatment Options for Dressler’s Syndrome
The treatment of Dressler’s Syndrome focuses on reducing inflammation and managing symptoms. Most individuals respond well to medical therapy, although some cases may require more invasive interventions.
Medical Management
- Nonsteroidal Anti-inflammatory Drugs (NSAIDs): These are the first line of treatment and work by reducing inflammation and alleviating pain. Commonly used NSAIDs include ibuprofen and aspirin.
- Colchicine: Often used in conjunction with NSAIDs, colchicine can help prevent recurrences and is effective in reducing inflammation.
- Corticosteroids: For individuals who do not respond to NSAIDs or colchicine, corticosteroids such as prednisone may be prescribed. These are potent anti-inflammatory agents but come with a risk of side effects and are generally used as a last resort.
Surgical Interventions
In rare cases, where there is significant pericardial effusion that does not respond to medical treatment, surgical intervention may be required.
- Pericardiocentesis: A procedure to remove excess fluid from the pericardial sac using a needle and catheter.
- Pericardiectomy: Surgical removal of part or all of the pericardium, typically reserved for chronic or constrictive pericarditis.
