Second, we did not account for the cross-over rate and exact
reasons for it, since these measures were not fully collected.
Third, we were unable to study the impact of the recent
improvement in the femoral technique, such as the reduction
of endovascular device diameter, early removal of the arterial
introducer, and preference for the femoral puncture technique
guided by fluoroscopy or ultrasound, which might translate into
a lower incidence of vascular complications.
Finally, the rate of bleeding complications may have been
low because operators participating in the KOTRI registry were
highly experienced in both the radial and femoral approaches.
Therefore, our results may not apply to all centres performing
radial procedures.
Conclusion
In the large, observational cohort of the KOTRI registry, TRI
was associated with favourable one-year clinical outcomes and
lower bleeding complications compared to TFI in patients with
NSTE-ACS undergoing PCI. Independent predictors of MACE
were clinical and angiographic profiles (CKD, MVD) rather than
vascular access sites. These data suggest that TRI may be the
preferred option in patients with NSTE-ACS.
This study was supported by the Soonchunhyang University Research Fund.
The funder had no role in the study design, data collection and analysis, deci-
sion to publish, or manuscript preparation.
