Dilated Cardiomyopathy


Dilated cardiomyopathy (DCM) develops when one or both of the ventricles (lower chambers of your heart) are damaged and become enlarged. The enlarged ventricles are too weak to pump blood to your body.

  • Diuretics help your body release fluid that has built up.
  • Blood pressure medicines lower your blood pressure and improve blood flow through your heart. Blood pressure medicines may include ACE inhibitors, beta-blockers, or nitrates.
  • Heart medicines help regulate your heart rhythm and strengthen your heartbeat.
  • Anticoagulants help prevent blood clots.


  • Telemetry is continuous monitoring of your heart rhythm.
  • Pulse oximetry measures the oxygen level in your blood.


  • An x-ray or MRI will show the size and thickness of your ventricles or if your heart is enlarged. If you have an MRI, you may be given dye to help the pictures show up better. Tell the healthcare provider if you have ever had an allergic reaction to contrast dye. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.
  • An echocardiogram uses sound waves to take pictures of your heart. The pictures show the size of your ventricles, and how well they are pumping blood.
  • Cardiac catheterization is a procedure used to see inside your heart and its blood vessels. X-rays and dye injected into your heart's blood vessels allow your healthcare provider to see blood move through your heart. Tell the healthcare provider if you have ever had an allergic reaction to contrast dye.


  • A surgically implanted device , such as a pacemaker or ventricular assist device (VAD), may be placed in your chest. The device may regulate your heartbeat or help your heart pump blood to your body.
  • Surgery may be done to treat other heart conditions and reduce your symptoms.


DCM may become life-threatening. DCM can cause your heart, lungs, and kidneys to stop working, or blood clots to form.
