Quick Summary:

  • Familial Hypertrophic Cardiomyopathy, also known as Heritable Hypertrophic Cardiomyopathy, is a condition where enlargement (hypertrophy) of the heart muscle cells occur. The enlargement or thickening of the heart muscle can be in the walls of the 4 heart chambers, or the septum that divides the chambers
  • The heart muscle, particularly the left ventricle, may thicken, causing the inside of the left ventricle to become smaller. This reduces the capability of left ventricle to relax sufficiently and hold enough blood. As a result, the outflow of blood is affected
  • The onset of Familial Hypertrophic Cardiomyopathy can occur at any age, though symptoms start most commonly in the 30s. A positive family history is the only risk factor known for this condition. However, certain underlying medical conditions, such as high blood pressure and uncontrolled diabetes, may exacerbate this heart condition
  • Mutations in several genes (including MYH7, MYBPC3, TNNT2, and TNNI3 genes) are known to cause the inherited form of hypertrophic cardiomyopathy. The pattern of inheritance is autosomal dominant, in which a single copy of the defective gene in each cell of an individual is sufficient to cause the condition
  • Familial Hypertrophic Cardiomyopathy can be asymptomatic, or present with symptoms such as chest pain, shortness of breath while lying down or sleeping, fatigue, dizziness, and palpitations. The diagnosis of the condition may involve tests such as echocardiography (ECG), electrocardiography (EKG), stress test, and coronary catheterization. If required, a biopsy of the heart muscle may be ordered
  • Some potential complications of Familial Hypertrophic Cardiomyopathy include a backflow of blood into the heart (heart valve regurgitation), aberrant heart beats (arrhythmia), sudden cardiac arrest, and dilated cardiomyopathy. Individuals with obstructive disease may develop end-stage or burn-out hypertrophic obstructive cardiomyopathy. These complications can be fatal
  • Familial Hypertrophic Cardiomyopathy may be treated with lifestyle changes, medications, non-surgical procedures, and surgical implants, depending on the severity of the condition. With early diagnosis and prompt treatment, the prognosis is generally good. However, in some individuals, a sudden cardiac arrest may the first presentation of the symptoms, which can even be fatal
  • Currently, there are no guidelines or methods available to prevent inherited forms of hypertrophic cardiomyopathy. Nevertheless, bringing about certain lifestyle changes and treating underlying medical conditions may help avoid or reduce severity of the symptoms
