Fibrinous Pericarditis: Understanding the Main Symptoms and Their Impact

Fibrinous pericarditis, also known as fibrinous inflammation of the pericardium, can arise from both infectious and non-infectious causes. Infectious triggers may include tuberculosis or other pyogenic infections, while non-infectious origins can be linked to post-myocardial infarction inflammatory responses, radiation therapy, or autoimmune diseases affecting the pericardium. This condition presents a distinct set of symptoms that can significantly affect a patient's well-being.

Key Symptoms of Fibrinous Pericarditis

Fever: When fibrinous pericarditis is caused by an infection, patients often experience high-grade fever. In contrast, those with non-infectious forms typically present with mild fever, usually below 38°C. The degree of temperature elevation can provide clues to the underlying cause of the inflammation.

Chest Pain: One of the most prominent features of fibrinous pericarditis is chest pain, which tends to be more intense compared to effusive pericarditis. This pain can be persistent and is often influenced by breathing, body position, and heart rate. The discomfort typically intensifies over time. The source of this pain lies in the deposition of fibrin-like substances on the pericardial surface, causing the normally smooth layers of the pericardium to become rough and irritated, leading to friction-related pain.

Additional Clinical Manifestations

Progressive Symptoms: As the condition evolves, fibrinous pericarditis may lead to the accumulation of fluid in the pericardial space. This can result in complications such as hypotension and dyspnea. These symptoms arise due to increased pressure on the heart from fluid buildup, potentially leading to more severe clinical presentations and requiring prompt medical attention.

Recognizing these symptoms early and understanding their progression is essential for timely diagnosis and effective management of fibrinous pericarditis. Patients experiencing persistent chest pain, unexplained fever, or signs of cardiac compression should seek medical evaluation to prevent potential complications.
