How is Ischemic CM diagnosed?
CM is diagnosed based on your medical history (symptoms and family medical history), physical exam, and other tests. Specific tests may include blood tests, electrocardiogram (ECG), chest X-ray, echocardiogram, exercise stress test, cardiac catheterization, CT scan, MRI scan, and radionuclide studies.
Occasionally, a myocardial biopsy may be performed to determine the cause of cardiomyopathy. During a myocardial biopsy, small tissue samples are taken from the heart and examined under a microscope to determine the cause of the cardiomyopathy.
