Diagnostic Criteria for Acute Pericarditis

Diagnostic criteria include the following:

    1. pericarditic typical chest pain,
    2. pericardial friction rubs,
    3. widespread ST segment elevation or PR depressions not previously reported, and
    4. new or worsening pericardial effusion.

A clinical diagnosis of acute pericarditis is made when at least 2 of these criteria are present.

A clinical diagnosis of myopericarditis is performed in patients with diagnostic criteria for acute pericarditis and 1 of the following features:

  1. evidence of elevated cardiac enzymes (creatine kinase-MB fraction, or troponin I or T) or

  2. new onset of focal or diffuse depressed left ventricular function by echocardiography.
