Genetic heart conditions are inherited disorders that affect the heart’s structure or function. They are caused by mutations in specific genes and can be passed down through families. Some individuals with a genetic heart condition may never experience symptoms, while others may develop serious complications such as arrhythmias, heart failure, or sudden cardiac death.
If you are living with or have had a heart condition, if you are a carer, friend or family member of someone with a heart condition, we want to hear from you.
In this section you can find out more about the types, causes, diagnosis, treatment and ongoing preventative measures for Genetic Heart Conditions
Genetic heart conditions are broadly classified into two main categories:
1. Cardiomyopathies (Inherited Heart Muscle Disorders)
Cardiomyopathy refers to diseases that affect the heart muscle, impacting its ability to pump blood efficiently. Over time, this can lead to heart failure, arrhythmias, or sudden cardiac death. The most common inherited cardiomyopathies include:
Hypertrophic Cardiomyopathy (HCM)
2. Channelopathies (Inherited Electrical Disorders of the Heart)
Channelopathies are conditions that affect the ion channels responsible for electrical signaling in the heart. They do not affect heart structure but can cause dangerous arrhythmias (irregular heart rhythms).
Common inherited channelopathies include:
Other Genetic Conditions That Increase Heart Disease Risk
Some genetic disorders do not directly cause heart disease but increase the likelihood of developing cardiovascular conditions.
Familial Hypercholesterolemia (FH)
Many people with genetic heart conditions may not experience symptoms, but when symptoms occur, they can include: • Palpitations (irregular or rapid heartbeats) • Fainting (syncope), especially during exercise or stress • Shortness of breath • Chest pain • Extreme fatigue • Swelling in the legs, feet, or abdomen (in cardiomyopathies)
In some cases, sudden cardiac arrest may be the first sign of a genetic heart condition, particularly in undiagnosed individuals.
Diagnosing a genetic heart condition typically involves:
If a person is diagnosed with a genetic heart condition, family members may be advised to undergo screening to determine their risk.
There is no cure for genetic heart conditions, but early diagnosis and medical management can reduce the risk of serious complications.
