A rare presentation of primary antiphospholipid syndrome

Area of Science:

• Cardiology
• Rheumatology
• Immunology

Background:

• Primary antiphospholipid syndrome (APS) is an autoimmune disorder characterized by recurrent thrombotic events and pregnancy morbidity.
• APS is associated with a hypercoagulable state due to antiphospholipid antibodies (aPLs).
• While venous thrombosis is common in APS, arterial thrombosis, particularly coronary artery disease (CAD), is less frequent but carries significant morbidity.

Observation:

• A young patient presented with myocardial infarction (MI).
• In-situ thrombosis was identified in the left anterior descending coronary artery and the right common iliac artery.
• The patient was diagnosed with primary antiphospholipid syndrome as the underlying cause.

Findings:

• This case illustrates a rare presentation of primary APS leading to severe arterial thrombosis, including acute myocardial infarction.
• The findings underscore the potential for antiphospholipid antibodies to directly contribute to the pathogenesis of coronary artery disease.
• Management strategies for this rare condition involve anticoagulation and addressing underlying autoimmune mechanisms.

Implications:

• This case emphasizes the importance of considering primary APS in young patients with unexplained arterial thrombosis and myocardial infarction.
• Early diagnosis and aggressive management of aPL-associated cardiovascular events are crucial for improving patient outcomes.
• Further research is warranted to elucidate the precise mechanisms linking aPLs to CAD and to optimize therapeutic approaches.
