Uraemia
TB
Post MI
SLE
R.A
Lung cancer
Clinical features of pericarditis
CP - Worse on lying flat
fever
Pericardial friction rub
Investigation findings of Percarditis
Widespread Saddle shaped ST elevation
PR depression
Raised troponin
ECHO - All patients
Management of pericarditis
Excercise restriction
NSAIDs and colchicine
2nd line - steroids
What is constrictive pericarditis and how does it present
scarring and loss of elasticity of the pericardial sac
fluid overload sx
Poor exercise tolerance / exertional dyspnoea
Raised JVO
Signs of cardiac tamponade
