Summary
Severe vascular disease in a 74-year-old woman stemmed from multiple genetic mutations, not classic risk factors. This highlights the impact of combined genetic predispositions on atherosclerosis and venous thromboembolism.
Area of Science:
- Vascular Medicine
- Genetics
- Cardiovascular Disease
Background:
- A 74-year-old woman presented with a complex history of vascular interventions spanning over 25 years.
- Her medical history included multiple arterial and venous events, such as stroke, pulmonary embolism, and peripheral artery occlusive disease.
Observation:
- Despite the extensive vascular disease, the patient lacked traditional risk factors like hypertension, diabetes, or hyperlipidemia.
- Genetic testing revealed several mutations: Factor V Leiden, methylenetetrahydrofolate reductase (MTHFR) C677T, HFE C282Y, plasminogen activator inhibitor-1 (PAI-1) gene mutation, -455 G/A fibrinogen gene polymorphism, apolipoprotein E (ApoE) epsilon3/epsilon4, and hyperhomocysteinemia.
Findings:
- The patient's severe, generalized occlusive vascular disease was attributed to a combination of genetic risk factors.
- These genetic factors likely contributed to both accelerated atherosclerosis and an increased risk of venous thromboembolism.
Implications:
- This case underscores the critical role of genetic predisposition in the development of severe vascular disease, even in the absence of conventional risk factors.
- Identifying and understanding these genetic risk factors is crucial for personalized risk assessment and management strategies in patients with complex vascular conditions.
