What are the common causes of acute pericarditis?
- Infection: Coxsackievirus, TB
- Uraemia

- worse on lying down

What investigations should be performed in suspected acute pericarditis?
- ECG
- Transthoracic echocardiography (TTE)
- Bloods: CRP/ESR, troponin
What are typical ECG findings in acute pericarditis?
- Widespread ‘saddle-shaped’ ST elevation
- PR depression (most specific sign)
Which patients with acute pericarditis should be admitted to hospital?

- Elevated troponin
What is the first-line treatment for most patients with acute pericarditis

How long should treatment for acute pericarditis typically continue?
Until symptoms and inflammatory markers resolve (1–2 weeks), then taper over 2–4 additional weeks
