Non-traumatic chest pain: pericarditis
Abstract
Pericarditis is an inflammation of the two layers of pericardium, the thin, sac-like membrane that surrounds the heart. Its causes are thought to be viral, fungal or bacterial. Pericarditis may also present as a result of a myocardial infarction. Its signs and symptoms include chest pain, which may radiate to the arm and jaw and pericardial friction rub (a scratching or creaking sound produced by the layers of the pericardium rubbing over each other) on auscultation of heart sounds. The diagnosis of straightforward pericarditis may be within the scope of practice of the emergency care practitioner. It should be possible for an emergency care practitioner to reach a working diagnosis and to initiate a treatment regimen, which would predominantly consist of providing analgesia to make the patient more comfortable.

This article will look at the pathophysiology, signs and symptoms/presentation and management of pericarditis. It will also examine the evidence and discuss the issues surrounding the need for hospital admission versus management within the community or primary care setting.
‘Pericarditis is inflammation of the pericardium, the protective sac that surrounds your heart. The pericardium has two layers (inner and outer) and can become inflamed if blood or fluid leaks between these two layers.’
The pericardium surrounds the cardiac muscle. It consists of two layers of tissue, encapsulating part of the aorta and vena cava (Knudson, 2011: 504). As well as protecting and restraining the heart, it determines cardiac filling by preventing the myocardium from becoming overstretched (Troughton et al, 2004: 718).
Pericarditis falls into two categories:
Evidence from the United States suggests that pericarditis is relatively rare, accounting for <1% of hospital admissions. It is most common in men aged 20–50 years, although it also occurs in women (Phelan et al, 2015).
