Insights
Sitosterolemia, a rare genetic disorder, caused juvenile coronary artery disease in a young man. Early diagnosis and bile acid-binding resin treatment can prevent severe atherosclerotic complications.
Area of Science:
- Cardiology
- Genetics
- Metabolic Disorders
Background:
- Sitosterolemia is a rare autosomal recessive disorder characterized by defective transport of plant sterols.
- Elevated plasma plant sterols lead to premature atherosclerosis, particularly in young individuals.
- Coronary artery disease is an uncommon manifestation in adolescents and young adults.
Observation:
- A 19-year-old male presented with acute myocardial infarction.
- Coronary angiography revealed rapid progression of atherosclerotic disease affecting three vessels within 8 months.
- Genetic testing confirmed the diagnosis of sitosterolemia.
Findings:
- Sitosterolemia is the underlying cause of premature coronary artery disease in this case.
- The patient experienced rapid progression of atherosclerosis due to plant sterol accumulation.
- Diagnosis of sitosterolemia is crucial for initiating appropriate management.
Implications:
- Early diagnosis of sitosterolemia can prevent severe cardiovascular events in young patients.
- Bile acid-binding resins are effective in reducing plant sterol levels and mitigating atherosclerotic progression.
- This case highlights the importance of considering rare genetic disorders in the evaluation of juvenile coronary artery disease.
Abstract:
This is a case report of a 19-year-old man who presented with acute myocardial infarction with obstruction of one coronary artery and rapid progression to three vessels in 8 months. He was proved to have sitosterolemia, a rare hereditary disease with plant sterol storing, resulting in juvenile coronary artery disease. Atherosclerotic complications can be preventable by administration of bile acid-binding resin, after the correct diagnosis is made. We introduce this disease with a review of the literature.
