About Dressler Syndrome (Postmyocardial Injury Syndrome)

Overview

Dressler syndrome, also known as post-cardiac injury syndrome or postmyocardial Injury syndrome, is a type of pericarditis. Pericarditis is the inflammation of the sac around the heart (pericardium). Dressler syndrome typically occurs after heart surgery, a myocardial infarction (heart attack), or an injury. It is thought to happen when the immune system responds excessively following one of these events. If left untreated, inflammation of the pericardium can lead to scarring, thickening, and muscle tightening of the heart, which can be life-threatening. Fortunately, Dressler syndrome is now considered very rare due to the development of modern treatments for heart attacks.

Causes and Risk Factors

Dressler syndrome occurs when the immune system responds excessively to an injury, such as heart surgery or a heart attack, leading to inflammation in the pericardium. The exact cause of Dressler syndrome is not fully understood. However, some known triggers include heart surgery, percutaneous coronary intervention, implantation of a pacemaker, cardiac ablation, and penetrating chest trauma.

Non-modifiable risk factors are risk factors that cannot be changed. Non-modifiable risk factors for Dressler syndrome include:

• Having had a heart attack
• Younger age
• Viral infections
• History of pericarditis
• Previous treatment with prednisone
• Surgeries that cause more damage to the heart muscle
• B-negative blood type
• Use of halothane anesthesia

Modifiable risk factors are risk factors that can be changed or influenced. Modifiable risk factors for Dressler syndrome are not well-documented. However, it is generally recommended to maintain a healthy weight, engage in regular physical activity, and follow a healthy diet. These lifestyle choices can help reduce the risk of various cardiovascular conditions.

Symptoms

The most common symptoms of Dressler syndrome include:

• Chest pain that worsens when lying down
• Chest pain that worsens with deep breathing or coughing (pleuritic pain)
• Fever without any known cause

It's important to note that symptoms can vary from person to person and may develop over several days or weeks. If you experience any of these symptoms or suspect you may have Dressler syndrome, it's essential to consult with your healthcare professional for an accurate diagnosis and appropriate management.

Diagnosis

To diagnose Dressler syndrome, doctors commonly perform the following examinations, tests, and procedures:

• Medical history: Your doctor will ask about your symptoms, medical history, and any recent heart surgery or heart attack.
• Physical examination: Your doctor will listen to your heart with a stethoscope to check for signs of inflammation or fluid near the heart, including a certain sound known as a “friction rub”.
• Blood tests: A complete blood count and blood cultures may be done to rule out infections and assess your overall health. Inflammatory markers may also be done.
• Echocardiogram: This test uses sound waves to create images of the heart and can help detect fluid near the heart or thickening in the pericardium (the sac around the heart).
• Electrocardiogram (ECG or EKG): This test records the electrical activity of your heart and can identify irregularities in your heart's electrical impulses.
• Chest X-ray: X-rays can show if there is an increase in heart size or fluid in the lungs.

Additional examinations, tests, and procedures to determine the stage or severity of Dressler Syndrome may include:

• Cardiac magnetic resonance imaging (MRI) scan: This imaging test provides detailed images of the heart and pericardium, helping assess the extent of inflammation or damage.
• Evaluation by various specialists: Depending on specific symptoms, consultations with specialists such as cardiologists, pulmonologists, or infectious disease specialists may be necessary.

Remember, these are general guidelines, and each individual case may vary. It's important to consult with your healthcare professional for personalized advice and guidance.

Treatment Options

The goals of treatment for Dressler syndrome are to reduce inflammation, manage symptoms, and prevent complications. Here are the recommended treatments and how they work:

Medications:

• Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen can help reduce inflammation and relieve pain.
• Colchicine, an anti-inflammatory medication, may be prescribed if OTC NSAIDs do not improve symptoms.
• Corticosteroids may be prescribed as a last resort to suppress the immune system and reduce inflammation.

Therapeutic Procedures:

• Pericardiocentesis: If there is cardiac tamponade (excess fluid around the heart), a needle or catheter is used to remove the fluid.
• Pericardiectomy: In cases of constrictive pericarditis, surgery may be performed to remove the pericardium.

Health Behavior Changes:

• Following the prescribed treatment plan, including medication dosing and duration.
• Seeking medical attention promptly if complications arise.

These treatments aim to reduce inflammation, manage symptoms, and prevent complications associated with Dressler syndrome. Remember to consult your healthcare professional for personalized advice.
