Recently, the term “autoreactive pericarditis” has been introduced to describe patients with identification of elements indicative of an autoimmune response who would otherwise be classed as idiopathic.
Diagnostic criteria include the following:
- pericarditic typical chest pain,
- pericardial friction rubs,
- widespread ST segment elevation or PR depressions not previously reported, and
- new or worsening pericardial effusion.
