What are the key clinical signs and symptoms that suggest a diagnosis of pericardial effusion in a primary care setting?

The provided context, consisting of titles from UK guidelines and PubMed literature, does not explicitly detail the key clinical signs and symptoms that specifically suggest a diagnosis of pericardial effusion in a primary care setting ¹,²,³,⁴,⁵,⁶,⁷ (Hoit, 2007) (Ceriani and Cogliati, 2016).

However, it indicates that pericardial effusion is a form of pericardial disease that can progress to pericardial tamponade (Hoit, 2007). The diagnosis of pericardial effusion often involves imaging techniques such as bedside ultrasound (Ceriani and Cogliati, 2016). While not specifically linked to pericardial effusion in the provided context, common symptoms encountered in primary care that might prompt investigation for various cardiac or respiratory conditions include dyspnoea ¹ and chest pain ³.
