Diagnostic Study of Choice

Study of choice

Echocardiography is the gold standard test for the diagnosis of dilated cardiomyopathy.

Diagnostic results

The following finding(s) on performing echocardiography is(are) confirmatory for dilated cardiomyopathy

• • Dilation of the left ventricle; however, may include dilatation of all 4 cardiac chambers
  • LV (left ventricular) wall thickness usually is normal but given the dilation the LV mass is increased
  • In addition there is a global reduction in systolic function
  • Occasionally there may also be focal wall motion abnormalities even in patients without flow limiting coronary artery disease

Name of Diagnostic Criteria

[Disease name] may be diagnosed at any time if one or more of the following criteria are met:

• Criteria 1
• Criteria 2
• Criteria 3
