Dilated Cardiomyopathy
Dilated cardiomyopathy (DCM) is a type of heart disease in which the walls of the pumping chambers of the heart (ventricles) stretch and thin out. This enlarges the chambers and weakens their ability to pump blood effectively. The most common type of cardiomyopathy, DCM is more likely to develop in men than women and typically begins in middle age. It can also occur in children.

Schedule with a cardiomyopathy specialistWhat Causes DCM?
The cause of dilated cardiomyopathy is often unknown. Although not considered primary risk factors, coronary artery disease and high blood pressure may increase the risk of developing DCM. Additional risk factors may include:
- Genetics
- Alcohol abuse and/or recreational drug use
- History of certain viral, bacterial or parasitic infections
- History of heart attack
- Autoimmune disorders
- Certain medications
Symptoms of Dilated Cardiomyopathy
When the disease is in its early stages, there may not be any symptoms. As the disease progresses and the ventricle walls become weaker, symptoms may include:
- Shortness of breath
- Fatigue
- Swelling in the legs, ankles and feet
- Chest pain
- Heart palpitations
- Dizziness or fainting
How Is DCM Diagnosed?
If a patient has any of the symptoms listed, a complete medical history will be taken and a physical exam performed. If DCM is suspected, one or more of the following diagnostic tests may be performed:
- Chest X-ray. Evaluates any enlargement of the heart.
- Echocardiogram. An ultrasound exam to evaluate the heart’s motion, blood flow and pumping efficiency of the ventricles.
- Electrocardiogram (ECG). A noninvasive test to record the heart’s electrical activity.
- Blood tests. Checks for infections or diseases that may contribute to the development of DCM.
- Exercise stress test. Evaluates how well the heart performs during exercise.
- Cardiac catheterization. A minimally invasive procedure to measure the pressure in and around the heart. In some cases, the procedure may also be used to take a biopsy of the heart muscle to check for damage.
Personalized Treatment for Dilated Cardiomyopathy
Treatment for DCM depends on how advanced the disease is, the severity of the symptoms and the cause. Treatment plans may include one or more of the following:
