Quality of anticoagulation with warfarin in this Saudi Arabian tertiary center was suboptimal, with a mean TTR of 59% and nearly 40% of time spent outside the therapeutic range.
Alyousif et al. (2016) conducted a cohort in nonvalvular atrial fibrillation (n=110). Warfarin was evaluated on time within therapeutic range (TTR). Warfarin therapy in patients with nonvalvular atrial fibrillation achieved a suboptimal mean time within therapeutic range of 59%, with 32.7% of patients having poor anticoagulation control.
