Study summary

The purpose of this study is to determine the genetic basis of cardiomyopathies and heart failure.

Read the detailed description

The purpose of this research study is to explore the causes and inheritances of cardiomyopathies. Cardiomyopathies are serious medical conditions that result in a wide range of cardiac problems, from no symptoms at all to heart failure. The underlying genetics of cardiomyopathies are poorly understood. This study will collect personal, family, and medical history information to create a database of participants with cardiomyopathies. This information will be used to identify inheritance patterns within families with cardiomyopathies. In addition, samples from participants will be studied in the lab to see if any changes in their genetic information can be identified that would cause a cardiomyopathy. Overall, the research study is aimed at determining the cause of these cardiac conditions so that tests and treatments might be developed in the future.

Study population

We are recruiting both local participants (who have been evaluated at UCI) and remote participants (who have been referred from outside UCI) with familial and simplex cases of hypertrophic, dilated, noncompaction, restrictive, and mitochondrial cardiomyopathies. As a control group, we are also recruiting patients with nuclear mutations known to increase the risk of cardiomyopathy, but who have not themselves developed cardiomyopathy.

Inclusion criteria

  • Individuals with a diagnosis of cardiomyopathy
  • Family members of individuals with a diagnosis of cardiomyopathy
  • Individuals with a nuclear mutation shown to confer risk of cardiomyopathy but who do not themselves have cardiomyopathy

Exclusion criteria

Exclusion Criteria:

  • Individuals who do not have cardiomyopathy, a relative with cardiomyopathy, or a nuclear mutation predisposing to cardiomyopathy
