    Pericarditis - after heart attack

    Dressler syndrome; Post-MI pericarditis; Post-cardiac injury syndrome; Postcardiotomy pericarditis

    Pericarditis is inflammation and swelling of the covering of the heart (pericardium). It can occur in the days or weeks following a heart attack.

    Causes

    Two types of pericarditis can occur after a heart attack.

    Early pericarditis: This form most often occurs within 1 to 3 days after a heart attack. Inflammation and swelling develop as the body tries to clean up the damaged heart tissue.

    Late pericarditis: This is also called Dressler syndrome. It is also called post-cardiac injury syndrome or postcardiotomy pericarditis. It most often develops several weeks or months after a heart attack, heart surgery, or other trauma to the heart. It can also happen about a week after a heart injury. Dressler syndrome is thought to occur when the immune system attacks healthy heart tissue by mistake.

    Things that put you at higher risk for pericarditis include:

    • A previous heart attack
    • Open heart surgery
    • Chest trauma
    • A heart attack that has affected the full thickness of your heart muscle

    Symptoms

    Symptoms include:

    • Anxiety
    • Chest pain from the swollen pericardium rubbing on the heart. The pain may be sharp, tight or crushing and may move to the neck, shoulder, or abdomen. The pain may also be worse when you breathe and go away when you lean forward, stand, or sit up.
    • Trouble breathing
    • Dry cough
    • Fast heart rate (tachycardia)
    • Fatigue
    • Fever (common with the second type of pericarditis)
    • Malaise (general ill feeling)
    • Splinting of ribs (bending over or holding the chest) with deep breathing

    Exams and Tests

    The health care provider will listen to your heart and lungs with a stethoscope. There may be a rubbing sound (called a pericardial friction rub, not to be confused with a heart murmur). Heart sounds in general may be weak or sound far away.

    A buildup of fluid in the covering of the heart or space around the lungs (pericardial effusion) is not common after a heart attack. But, it often does occur in some people with Dressler syndrome.

    Tests may include:

    Treatment

    The goal of treatment is to make the heart work better and reduce pain and other symptoms.

    Aspirin may be used to treat inflammation of the pericardium. A drug called colchicine is often used as well.

    In some cases, excess fluid surrounding the heart (pericardial effusion) may need to be removed. This is done with a procedure called pericardiocentesis. If complications develop, part of the pericardium may sometimes need to be removed with surgery (pericardiectomy).

    Outlook (Prognosis)

    The condition may recur in some cases.

    Possible Complications

    Possible complications of pericarditis are:

    When to Contact a Medical Professional

    Contact your provider if:

    • You develop symptoms of pericarditis after a heart attack
    • You have been diagnosed with pericarditis and symptoms continue or come back despite treatment

      • Acute MI

        Acute MI - illustration

        A heart attack or acute myocardial infarction (MI) occurs when one of the arteries that supplies the heart muscle becomes blocked. Blockage may be caused by spasm of the artery or by atherosclerosis with acute clot formation. The blockage results in damaged tissue and a permanent loss of contraction of this portion of the heart muscle.

      • Pericardium

        Pericardium - illustration

        The pericardium is a thin double-layered sac which encloses the heart. Fluid is contained within the layers and lubricates the constantly rubbing surfaces.

        Pericarditis post-IM - illustration

        Post-MI pericarditis is inflammation of the pericardium, the sac-like covering of the heart. Any previous injury to the heart muscle can cause pericarditis. Incidences of pericarditis are associated with Dressler syndrome, after a heart attack, open heart surgery, and may also follow stab wounds to the heart or blunt chest trauma. Pain occurs when the inflamed pericardium rubs on the heart.
