Identify three causes of acute pericarditis
- Viral pericarditis
- Post MI pericarditis (Dressler’s syndrome)
- Uraemic pericarditis
- Bacterial pericarditis

- Malignant pericarditis
Identify three risk factors for pericarditis
- Male sex
- Age 20 to 50 years
- Cardiac surgery
- Viral and bacterial infections
Identify three clinical features of acute pericarditis

- Pericardial friction rub heard during expiration
- Referred pain to left shoulder, arm or abdomen
- Fever
- Arthralgia
Identify three clinical features of chronic constrictive pericarditis
- Kussmaul’s sign (rise in JVP during inspiration)
- Pulsus paradoxus (fall in BP during inspiration)
- Systemic venous congestion (ascites, hepatomegaly, peripheral oedema)
- Pulmonary venous congestion (dyspnoea, cough, orthopnoea).

- Small heart
Identify three differential diagnoses of pericarditis
- Myocardial infarction
- Pulmonary embolism
- Pneumothorax
- Costochondritis
What is the management of pericarditis?
- Bed rest
