Subclinical atherosclerosis in primary antiphospholipid syndrome

Area of Science:

• Cardiovascular Medicine
• Rheumatology
• Vascular Biology

Background:

• Primary antiphospholipid syndrome (PAPS) is a condition associated with an increased risk of blood clots.
• The potential for accelerated atherosclerosis in PAPS patients is not fully understood.
• Carotid intima media thickness (IMT) is a marker for subclinical atherosclerosis.

Purpose of the Study:

• To investigate the hypothesis that atherosclerosis is increased in patients with PAPS.
• To compare carotid IMT between PAPS patients, individuals with inherited thrombophilia, and healthy controls.

Main Methods:

• Carotid artery intima media thickness (IMT) was measured in 44 PAPS patients, 25 with inherited thrombophilia, and 34 controls.
• Cardiovascular risk factors including smoking, hypertension, and dyslipidemia were assessed.
• Data were analyzed across different age groups.

Main Results:

• Cardiovascular risk factors were similarly distributed across all study groups.
• No significant difference in IMT was observed between groups in individuals under 40 years old.
• PAPS patients over 40 years demonstrated significantly greater IMT in the common carotid, bifurcation, and internal carotid arteries compared to controls.

Conclusions:

• Atherosclerosis may be a developing concern for primary antiphospholipid syndrome patients aged 40 and older.
• Increased carotid IMT in older PAPS patients suggests a potential link between PAPS and accelerated vascular disease.
• Further research is warranted to elucidate the mechanisms and clinical implications of atherosclerosis in PAPS.
