Cardiomyopathy can affect children, adults and older people

Cardiomyopathy can affect people of all ages, including children, working-age adults and older people, depending on the underlying type and cause.

Many people with cardiomyopathy have no symptoms in the early stages

Many people with cardiomyopathy have few or no symptoms in the early stages, and the condition may be detected through imaging, routine tests, or family screening.

Genetics plays a role in many cardiomyopathies

Many cardiomyopathies have a genetic component, and inherited forms are common in conditions such as hypertrophic, dilated and arrhythmogenic cardiomyopathy.

Many people with cardiomyopathy live full and active lives

With appropriate diagnosis, monitoring and treatment, many people with cardiomyopathy are able to live full and active lives.

Early diagnosis and regular follow-up can improve quality of life

Early diagnosis, risk assessment and regular follow-up are central to cardiomyopathy care and can help improve quality of life and long-term outcomes.
