Outcomes between PE-only and AF cohorts
After propensity matching, there was no substantial difference in the baseline characteristics between the PE alone and AF cohorts (Supplemental table 2). Clinical outcomes between PE-only and AF cohorts were shown in Supplemental table 7. The incidence of the arterial thromboembolic event was lower in the PE-only cohort than that in AF cohort (SHR, 0.52; 95% CI, 0.48–0.56) (Figure 4A). The risk of ischemic stroke was lower in the PE-only cohort (SHR, 0.41; 95% CI, 0.37–0.45) (Figure 4B) with no differences in ECATE (Figure 4C) and MI event rates (Supplemental table 7). The PE-only cohort had higher all-cause mortality (HR, 1.26; 95% CI, 1.20–1.32) and CV death (HR, 1.14; 95% CI, 1.07–1.22) than the AF cohort (Figure 4D and Figure 4E).
