Figures
- Fig 1.
Distribution of ARU in patients receiving dual antiplatelet therapy. Most patients are within the target inhibition range, <550 ARU (dotted line).
- Fig 2.
Distribution of values associated with clopidogrel response in patients receiving dual antiplatelet therapy. A, BASE value. B, PRU. C, Percentage inhibition. The working cutoff value is 40% (dotted line).
- Fig 3.
Variability of PRU according to the duration of dual antiplatelet therapy. CI indicates confidence interval.
- Fig 4.
Changes in PRUs (A) and percentage inhibition (% inhibition) (B) after an additional clopidogrel loading dose in 10 patients. Results are shown for initial (PRU1 and % inhibition1) and follow-up tests after an additional loading dose of clopidogrel (PRU2 and % inhibition2).
