Purpose

This study aimed to evaluate the quality of anticoagulation control in patients with primary antiphospholipid syndrome, using time in therapeutic range.

Methods

Anticoagulation quality was assessed in a retrospective study including patients with primary Antiphospholipid Syndrome.

n = 93 patients

Results

34.4%

just over a third stayed safely anticoagulated, most were not

n = 93 patients

More results

Among these, 32 patients (74.4 achieved time in therapeutic range ≥60%, with a median time in therapeutic range of 89.3%.

However, 61 patients (65.6%) had insufficient follow-up, resulting in an incalculable time in therapeutic range.

More results

No significant differences were observed between patients with good and poor anticoagulation control regarding demographic or clinical variables.

Conclusion · 1 of 2

Our findings indicates that only 34.4% of patients with primary antiphospholipid syndrome achieved adequate anticoagulation control and inadequate follow-up remains a major barrier.

Conclusion · 2 of 2

Further studies are needed to identify factors contributing to suboptimal time in therapeutic range and to improve anticoagulation management in this high-risk population.
