Learn About Cardiomyopathy
Cardiomyopathy is disease in which the heart muscle becomes weakened, stretched, or has another structural problem. It often contributes to the heart's inability to pump or function well.
Many people with cardiomyopathy have heart failure.
There are many types of cardiomyopathy, with different causes. Some of the more common causes are:
- Dilated cardiomyopathy (also called idiopathic dilated cardiomyopathy if there is no known cause) is a condition in which the heart becomes weak and the heart's chambers get large. As a result, the heart cannot pump enough blood out to the body. It can be caused by many medical problems.
- Hypertrophic cardiomyopathy (HCM) is a condition in which the heart muscle becomes thick. This makes it harder for blood to leave the heart. This type of cardiomyopathy is most often passed down through families.
- Ischemic cardiomyopathy is caused by a narrowing of the arteries that supply the heart with blood. It makes the heart walls thin so they do not pump well.
- Restrictive cardiomyopathy is due to a group of disorders. The heart chambers are unable to fill with blood because the heart muscle is stiff. The most common causes of this type of cardiomyopathy are amyloidosis and scarring of the heart from an unknown cause.
- Peripartum cardiomyopathy occurs during pregnancy or in the first 5 months afterward.
When possible, the cause of cardiomyopathy is treated. Medicines and lifestyle changes are often needed to treat the symptoms of heart failure, angina, and abnormal heart rhythms.
Procedures or surgeries may also be used, including:
- A defibrillator that sends an electrical pulse to stop life-threatening abnormal heart rhythms
- A pacemaker that treats a slow heart rate or helps the heart beat in a more coordinated fashion
- Coronary artery bypass (CABG) surgery or angioplasty that may improve blood flow to the damaged or weakened heart muscle
- Heart transplant that may be tried when all other treatments have failed
Partially and fully implantable mechanical heart pumps have been developed. These may be used for very severe cases. However, not all people need this advanced treatment.

The outlook depends on many different things, including:
- Cause and type of cardiomyopathy
- The severity of the heart problem
- How long the problem has been present
- How well the condition responds to treatment
Heart failure is most often a long-term (chronic) illness. It may get worse over time. Some people develop severe heart failure. In this case, medicines, surgery, and other treatments may no longer help.
People with certain types of cardiomyopathy are at risk for dangerous heart rhythm problems.
Summary: The purpose of this study is to assess the safety and feasibility of the investigational catheter for mapping the atrial and ventricular regions of the heart.
Summary: The purpose of this pilot study is to evaluate Fluorodeoxyglucose - Positron Emission Tomography (FDG-PET) as an imaging modality to diagnose and risk stratify subclinical, imaging negative ICI-myocarditis, and to determine whether subclinical ICI-induced myocarditis is a distinct and clinically relevant entity with a risk of progression to fulminant myocarditis.
