Figure 2 Relationship between Thrombolysis In Myocardial Infarction (TIMI) flow grade before percutaneous coronary intervention (PCI) and baseline cartridge adenosine diphosphate (CADP) closure time (CADP-CT). Lower TIMI flow at first angiogram was associated with higher platelet reactivity (PR). CADP-CT was 73 ± 11 in the TIMI flow grade 0/1 group versus 87 ± 8 in the TIMI flow grade 2/3 group (p < 0.001), and % platelet aggregation was, respectively, 91 ± 4 versus 85 ± 3 (p < 0.001). CADP-CT was 75 ± 11 in the TIMI flow grade 0/1/2 group versus 89 ± 6 in the TIMI flow grade 3 group (p = 0.03), and %PA was, respectively, 90 ± 4 versus 84 ± 2 (p = 0.01).
