(what's this?)
PatientPlus articles are written for doctors and so the language can be technical. However, some people find that they add depth to the articles found in the other sections of this website which are written for non-medical people.
Dressler's Syndrome
This is classically a post-myocardial infarction syndrome, usually occurring 2 to 5 days after the initial event but it can be delayed for as long as 3 months. There appears to be an immunological reaction that leads to pericarditis. The term Dressler's syndrome is often applied to a similar condition of similar aetiology that occurs after cardiotomy for open-heart surgery and even sometimes after blunt or penetrating trauma to the chest. Postcardiac injury syndrome also has been observed after cardiac surgery, percutaneous intervention, pacemaker implantation, and radiofrequency ablation.1
Autopsy shows localised fibrinous pericarditis. It is thought that the condition is immunologically mediated and antiheart antibodies may be found.
The original paper by Dressler in 19562 suggested an incidence of 3 to 4% of all cases of acute myocardial infarction but it is now much rarer at around 4 in 100,000 cases, according to the British Heart Foundation. This is thought to be due to modern methods of management.3 One reason may be that active intervention reduces the size of the infarct.4 Some have argued that the syndrome has not vanished but never really existed as a separate entity.5
If a person has had a previous episode, it is more likely to recur. It seems more likely to occur after a large infarct.
- It usually presents 3 to 5 days after the initial episode with pain and fever that may suggest further infarction.
- The pain is the main symptom, often in the left shoulder, often pleuritic, and worse on lying down.
- There may be malaise, fever and dyspnoea.
- Rarely, it may cause cardiac tamponade or acute pneumonitis.
- A pericardial friction rub may be heard. The typical sound of pericarditis is described as like the sound of boots walking over fresh snow.
The pain may initially suggest a further episode of angina or MI. Pleuritic chest pain may also suggest pneumonia or pulmonary embolism.
- FBC will show leucocytosis, sometimes with eosinophilia and an elevated ESR.
- Serology may show heart autoantibodies.
- ECG may show ST elevation in most leads without reciprocal ST depression, typical of pericardial effusion.
- Echocardiography shows pericardial effusion.
- MRI scan may show an effusion.
- Chest x-ray shows pleural effusions in 83%, parenchymal opacities in 74%, and an enlarged cardiac silhouette in 49%.
- Aspirin may be given in large doses.
- Other NSAIDs or corticosteroids may be used, especially if there are severe and recurrent symptoms.
- Steroids are particularly valuable where severe symptoms have required pericardiocentesis, and when infection has been excluded.
- In resistant or recurrent cases, colchicine may be useful.
- If there is significant pericardial effusion then pericardiocentesis, involving aspiration of the fluid, may be required to relieve the constriction on the heart.
- Pleuritic pain may be associated with pleurisy and pleural effusion.
- Significant pericardial effusion can cause cardiac tamponade.
- Inflammation can result in constrictive pericarditis.
It can follow a relapsing course but the outcome is usually favourable.
It is likely that modern techniques that involve the use of anti-inflammatory drugs such as aspirin have helped to reduce the incidence of this syndrome.3 Prophylactic use of steroids before cardiac surgery offers no benefit.1
