Familial Hypercholesterolemia

Familial Hypercholesterolemia (FH) is a genetic condition that causes high levels of cholesterol in the blood. This article aims to provide a clear and concise explanation of FH, including its types, causes, symptoms, diagnostic tests, treatments, and available drugs. We’ll use simple language to enhance readability and accessibility.

Familial Hypercholesterolemia (FH):

FH is a genetic disorder that affects the way your body processes cholesterol, a fatty substance found in your blood. There are two main types of FH:

  1. Heterozygous FH (HeFH): In HeFH, you inherit a faulty gene from one parent, leading to high cholesterol levels from birth.
  2. Homozygous FH (HoFH): HoFH is a more severe form where both parents pass on faulty genes, causing extremely high cholesterol levels.

Causes of FH 

  1. Genetic Inheritance: FH is primarily caused by inheriting abnormal genes from one or both parents.
  2. Family History: If FH runs in your family, your risk is higher.
  3. Gene Mutations: Specific gene mutations, like LDLR, APOB, or PCSK9, can trigger FH.
  4. Diet: A diet rich in saturated fats can worsen FH.
  5. Obesity: Being overweight can contribute to higher cholesterol levels.
  6. Physical Inactivity: Lack of exercise can exacerbate FH.
  7. Smoking: Smoking is a risk factor for heart disease, which can worsen FH.
  8. Alcohol Consumption: Excessive alcohol intake may affect cholesterol levels.
  9. Certain Medications: Some medications can raise cholesterol.
  10. Hypothyroidism: An underactive thyroid gland can impact cholesterol levels.
  11. Kidney Disease: Kidney problems may affect cholesterol regulation.
  12. Diabetes: Uncontrolled diabetes can worsen FH.
  13. Polycystic Ovary Syndrome (PCOS): PCOS can lead to higher cholesterol levels.
  14. Stress: Chronic stress can influence cholesterol.
  15. Age: Cholesterol levels tend to rise with age.
  16. Gender: Men generally have higher cholesterol levels than premenopausal women.
  17. Pregnancy: Some women experience increased cholesterol during pregnancy.
  18. Liver Disease: Liver conditions can affect cholesterol processing.
  19. Metabolic Syndrome: FH may be linked to metabolic syndrome.
  20. Lifestyle Choices: Unhealthy habits can worsen FH’s effects.

Symptoms of FH 

  1. Xanthomas: Fatty deposits under the skin, usually around the eyes and tendons.
  2. Corneal Arcus: A white or grayish ring around the cornea of the eye.
  3. High Cholesterol Levels: Total cholesterol levels above 300 mg/dL.
  4. Premature Heart Disease: Increased risk of heart attacks and strokes at a young age.
  5. Chest Pain (Angina): Due to blocked arteries.
  6. Yellowish Patches on Skin: Often seen on the elbows, knees, and hands.
  7. Tendon Thickening: Tendons become swollen and painful.
  8. Pale or Grayish-colored Nails: Sometimes an FH indicator.
  9. Swollen Ankles: Fluid buildup can occur in the lower extremities.
  10. Shortness of Breath: May be a sign of heart involvement.
  11. High Blood Pressure: An associated risk factor.
  12. Frequent Fatigue: Reduced blood flow to the heart.
  13. Stroke: FH increases the risk of stroke.
  14. Peripheral Artery Disease: Reduced blood flow to the limbs.
  15. Cognitive Impairment: FH can affect brain function.
  16. Chest Tightness: Often a precursor to angina.
  17. Abdominal Pain: Due to pancreatitis in some cases.
  18. Yellowish Bumps on Skin: Similar to xanthomas.
  19. Calf Pain: May indicate reduced blood flow to the legs.
  20. Rapid Weight Gain: Fluid retention can cause sudden weight changes.

Diagnostic Tests for FH 

  1. Cholesterol Blood Test: Measures total cholesterol, LDL, HDL, and triglyceride levels.
  2. Genetic Testing: Identifies specific FH-related gene mutations.
  3. Physical Examination: Detects xanthomas and other physical signs.
  4. Family History Analysis: Identifies FH patterns in your family.
  5. Corneal Examination: Checks for corneal arcus.
  6. Tendon Examination: Looks for tendon thickening.
  7. CT Scan: Images of coronary arteries to assess blockages.
  8. MRI: Helps visualize blood flow and plaque buildup.
  9. Echocardiogram: Assesses heart function.
  10. Stress Test: Monitors heart’s response to exertion.
  11. Angiography: X-ray of blood vessels after dye injection.
  12. Carotid Ultrasound: Evaluates neck artery blockages.
  13. Electrocardiogram (ECG): Records heart’s electrical activity.
  14. ABI Test: Measures blood pressure in arms and legs to detect artery blockages.
  15. Lipid Profiling: Detailed lipid analysis for accurate diagnosis.
  16. C-reactive Protein Test: Assesses inflammation and heart disease risk.
  17. Apolipoprotein B Test: Measures a protein associated with LDL.
  18. Thyroid Function Test: Checks for hypothyroidism.
  19. Liver Function Test: Rules out liver-related causes.
  20. Glucose Test: Screens for diabetes.

Treatments for FH 

  1. Lifestyle Changes: Adopt a heart-healthy diet and exercise regularly.
  2. Medications: Statins, bile acid sequestrants, PCSK9 inhibitors, and niacin can lower cholesterol.
