Idiopathic Dilated Cardiomyopathy

What Is Idiopathic Dilated Cardiomyopathy?

Idiopathic dilated cardiomyopathy (IDCM) is a type of heart disease where the walls of your heart become abnormally large and thin, reducing its ability to pump blood. It is a chronic condition, meaning that it can't be cured, but treatments can help manage the symptoms and slow the progression of the disease. IDCM is sometimes referred to as idiopathic dilated cardiomyopathy (IDCM) or dilated cardiomyopathy (DCM).

Causes of Idiopathic Dilated Cardiomyopathy

IDCM is usually caused by a virus, either directly infecting the heart muscle itself, or causing inflammation or damage to the heart muscle. It can also be caused by genetic mutations and some autoimmune diseases.

Symptoms of Idiopathic Dilated Cardiomyopathy

  • Shortness of breath
  • Fatigue
  • Swollen ankles and feet
  • Fainting spells
  • Rapid or irregular heartbeats
  • Chest pain
  • Heart murmur

Diagnosis of Idiopathic Dilated Cardiomyopathy

IDCM is typically diagnosed through a medical history, physical exam, and diagnostic tests such as an echocardiogram (ultrasound of your heart), X-ray imaging studies, electrocardiogram (ECG), cardiac MRI, or blood tests.

Treatments for Idiopathic Dilated Cardiomyopathy

Treatment for IDCM usually includes medications to reduce the strain on the heart, such as beta blockers or ACE inhibitors, as well as lifestyle changes to reduce the risk of further heart damage. In some cases, surgery may be required to repair the heart muscle or replace a diseased heart valve.
