The workup in a patient with suspected cardiomyopathy may include the following:

  • Complete blood count

  • Comprehensive metabolic panel

  • Thyroid function tests

  • Iron studies

  • Cardiac biomarkers

  • B-type natriuretic peptide assay

  • Chest radiography

  • Echocardiography

  • Cardiac magnetic resonance imaging (MRI) with gadolinium

  • Electrocardiography (ECG)

  • Endocardial biopsy

  • Cardiac catherization

In addition, a urine toxicology screen is used to detect drugs associated with risk for dilated cardiomyopathy, including cocaine and methamphetamine.

Endomyocardial biopsy has limited usefulness in the evaluation of dilated cardiomyopathy. However, it may be helpful in diagnosing myocarditis, connective tissue disorders, and amyloidosis.
