Cardiomyopathy (Dilated) (cont.)
How Is DCM Diagnosed?
DCM is diagnosed based on medical history (your symptoms and family history), physical exam, and tests:
such as blood tests, electrocardiogram , Chest X-ray , echocardiogram , exercise stress test , Cardiac Catheterization ,
CT scan , MRI and radionuclide studies ( Multigated Acquisition Scan ).
Another test occasionally done to determine the cause of a
cardiomyopathy is a
myocardial biopsy
where a tissue sample is taken from the heart and examined under a microsope to
determine the cause of the symptoms.
Relatives of those with familial DCM should be screened for DCM.
Testing would be the same as mentioned above (medical history, physical exam,
ECG, echocardiogram, etc.). Genetic testing may also be available to identify
abnormal genes.
How Is DCM Treated?
Treatment of DCM is aimed at correcting the cause of the condition wherever
possible. Another major goal is to decrease the heart size and decrease the
substances (hormones) in the bloodstream that enlarge the heart and ultimately
lead to worsened symptoms. Patients usually take several medications to treat
the heart failure. Doctors also recommend a variety of lifestyle changes.
What Medications Are Used to Treat DCM?
To manage heart failure, most people improve by taking a beta-blocker , ACE inhibitors
, and/or diuretics . If you have an
arrhythmia,
your doctor may give you a medication to control your heart rate or lessen the
occurrence of arrhythmias. Blood thinners may be used to prevent blood clots
from occurring. Your doctor will discuss what medications are best for you.
