Objective:

To evaluate the clinical outcomes of Indonesian AF patients receiving warfarin-based treatment.

Approach:
  • Study Design: The OPTIMA study is a multicenter, prospective cohort study involving 1,599 AF patients across 25 centers in Indonesia.
  • Data Collection: Clinical characteristics, INR levels, and time in therapeutic range (TTR) were analyzed.
  • Endpoints: Primary endpoints included stroke/systemic embolism (efficacy) and major bleeding (safety).
  • Statistical Analysis: Cox proportional hazards regression and Kaplan–Meier analysis were used to assess outcomes.
Key Findings:
  • Mean CHA2DS2-VASc score was 2.43.
  • Mean time in therapeutic range (TTR) was only 30.1%.
  • Incidence rates per 100 patient-years were 1.32 for stroke, 1.51 for major bleeding, and 3.15 for mortality.
  • Stroke risk was highest in persistent/permanent AF, particularly affecting younger, working-age individuals.
Interpretation:

Warfarin management at the standard INR target of 2.0–3.0 was associated with poor anticoagulation quality.

Limitations:
  • The study's findings require confirmation in prospective trials.
  • Socioeconomic factors may influence the burden of AF-related strokes.
Conclusion:

Patients with average INR values of 1.6–2.5 experienced lower rates of stroke and major bleeding.
