Overview
Dressler's syndrome or post myocardial infarction syndrome is a form of pericarditis that occurs in the setting of injury to the heart as a result of myocardial infarction. Dressler's syndrome typically occurs 2 to 10 weeks after myocardial infarction. This differentiates Dressler's syndrome from the much more common post myocardial infarction pericarditis which occurs between days 2 and 4 after myocardial infarction.
Historical Perspective
- Dressler's syndrome was first characterized by William Dressler in 1956.
- It should not be confused with the Dressler's syndrome of hemoglobinuria, named after Lucas Dressler who characterized it in 1854.[1][2][3]
Classification
- There is no established system for the classification of Dressler's syndrome.
Pathophysiology
- Although the exact cause remains unknown, Dressler's syndrome is believed to result from an autoimmune inflammatory reaction to myocardial neo-antigens, as well as injury to the mesothelial pericardial cells.
- It usually occurs within weeks or months of the infarction due to antimyocardial antibodies; this begins with myocardial injury that releases cardiac antigens and stimulates antibody formation.
- The immune complexes that are generated as anti-actin and actomycin antibodies deposit onto the pericardium and causes inflammation.
- The autoimmune response and syndrome may also develop secondary to pulmonary embolism.[4]
Gross Pathology
Causes
The common causes of Dressler's syndrome include:
- Surgeries associated with myocardial damage as
- Coronary artery bypass grafting and
- Aortic valve replacement.
- Myocardial infarction (heart attack)
- Pulmonary embolism
Differentiating Dressler's Syndrome from other Diseases
Dressler's syndrome typically occurs 2 to 10 weeks after a myocardial infarction has occurred.[6][7] This differentiates Dressler's syndrome from
- Post myocardial infarction pericarditis that occurs in 17,000 to 25,000 in every 100,000 cases of acute myocardial infarction between days 2 and 4 after the myocardial infarction.
- Pulmonary embolism, another identifiable cause of pleuritic (and non-pleuritic) chest pain in people who have been hospitalized and/or undergone surgical procedures within the preceding weeks.
Further, Dressler's syndrome should be differentiated from:
- Congestive Heart Failure
- Influenza
- Acute anemia with or without gastrointestinal bleeding
- Uremia
Epidemiology and Demographics
- Incidence: In the setting of myocardial infarction, Dressler's syndrome occurs in about 3 to 4% of MI cases.[8]
- Dressler's syndrome was more commonly seen in the era prior to reperfusion, but its incidence has markedly decreased in the reperfusion era, presumably because of smaller infarct sizes.[9]
- Age: Dressler's syndrome occurs more often in younger age groups.
- Gender: There is no gender predilection for Dressler's syndrome.
- Race: There is no racial predilection for Dressler's syndrome.
- Mortality rate: The mortality rate can reach up to 60% in hospital setting.
Risk Factors
- The risk of Dressler's syndrome increases with the size of the infarction.
- Further, a former episode of Dressler's syndrome increases the risk of relapse upon recurrent MI.
- Epidemiological studies showed a higher risk ratio of Dressler's syndrome with:
- Cardiac surgeries associated with greater myocardial damage as aortic valve replacement.
- Younger age
- Prior treatment with prednisone
- B -ve blood type
- Halothane anesthesia
- Viral infections that have been associated with Dressler's syndrome (based on the seasonal variations in incidence and elevated blood levels of viral components in Dressler's Syndrome patients) include:
Screening
- There is insufficient evidence to recommend routine screening for Dressler's syndrome.
Natural History, Complications, and Prognosis
- Pericardial effusion may result from the accumulation of fluids as a result of inflammation in the pericardial sac.
- Cardiac tamponade can occur if the accumulation of fluids in the pericardium is large enough and rapid enough.Classic findings of tamponade include Beck's triad:
- Low blood pressure
- Distended neck veins (JVD)
- Muffled/distant heart tones
- Constrictive pericarditis can occur if there is a chronic inflammatory response
Diagnosis
Symptoms
The syndrome consists of a persistent low-grade fever, and chest pain which is usually pleuritic in nature.The symptoms tend to occur after a few weeks or even months after myocardial infarction and tend to subside in a few days.
- Malaise/generalized weakness
- Irritability
- Decreased appetite
- Dyspnea (with or without hypoxia)
- Palpitations/tachycardia
- Arthralgias
Physical Examination
Cardiovascular Examination
- Pericardial friction rub: This characteristic sign may disappear secondary to either improvement in or worsening of accumulation of pericardial fluid
- Tachycardia
- Pulsus paradoxus (>10 mmHg decrease in blood pressure with inspiration and decreased pulse amplitude on the radial artery).
- Signs of pneumonitis (e.g., a cough, decreased oxygen saturation, fever).
- Minimal respiratory symptoms to significant respiratory distress with large pleural effusions.
Laboratory Findings
Elevated ESR.
Imaging Findings
- An echo will allow for evaluation of the pericardial fluid, if present, and help discern the exact cause of reduced cardiac output (i.e., determine whether truly DS or another condition such as congestive heart failure).
- An echo will further allow for evaluation of ventricular contractility, in addition to assessment of the potential risk of cardiac tamponade (i.e., if cardiac chambers appear compressed by pericardial fluid). The more pericardial fluid that is accumulated, the easier it is to detect its presence by echocardiography.[10]
- Whilst definitive evaluation with formal echocardiogram is the gold standard, bedside cardiac ultrasound.
- If it is difficult to assess the posterior pericardium with an echo, cardiac magnetic resonance imaging (MRI) may employed to determine whether there is an effusion present. In some instances, fluid collections become loculated.[11]
- A chest x-ray will reveal flattening of the costophrenic angles and be employed if echocardiography is not available enlargement of the cardiac silhouette as a result of both pleural and pericardial effusions.[12]
- An electrocardiograph (ECG) initially demonstrate ST segment elevation and T-wave inversion, such as with pericarditis. Further inflammation of the myocardium will also result in ST segment elevations. Both electrical alternans (variation in amplitude or directionality of QRS from beat to beat) and/or a low voltage QRS.
Treatment
Medical Therapy
Dressler's syndrome is typically treated with high dose (up to 650 mg PO q 4 to 6 hours) enteric-coated aspirin. Acetaminophen can be added for pain management as this does not affect the coagulation system. Anticoagulants should be discontinued if the patient develops a pericardial effusion.[13]
NSAIDs such as ibuprofen should be avoided in the peri-infarct period as they:
- Increase the risk of reinfarction
- Adversely impact left ventricular remodeling
- Block the effectiveness of aspirin
