3.2 Effects of antithrombotic use on complications after
ST
The background of patients according to their CAT status is summarized
in Table 2. Patients undergoing CAT had significantly higher values of
APTT (p = 0.002) and PT-INR (p = 0.006) than those of antithrombotic
naïve patients.
No statistically significant difference was observed in the number of
patients with any complications between patients undergoing CAT (63%)
and antithrombotic naïve patients (73%). Comparisons of each
postoperative complication (bleeding, infection, and subcutaneous
emphysema) also revealed no significant differences between the two
groups (Table 3).
