Etiology
Idiopathic, neoplastic (chemotherapy and radiation), autoimmune, viral, tuberculosis, bacterial (nontuberculous), uremia, post–cardiac surgery, trauma, post–myocardial infarction, drugs, dissecting aortic aneurysm, hypothyroidism.
Pathophysiology
- The pericardium is a fibrous sac surrounding the heart consisting of two layers: a thin visceral layer attached to the myocardium and a thicker parietal layer.
- The pericardial space is normally filled with 15–50 mL of fluid, and the two layers slide smoothly against each other, allowing for normal expansion and contraction of the heart.
- Pericarditis occurs when these layers are inflamed.
