Complex PCI was defined by one of the following characteristics: \u22653 stents, \u22653 lesions, bifurcation with 2 stents, total stent length \u226560 mm, left main PCI, or chronic total occlusion PCI. Net adverse clinical events, ischemic composite outcomes, and bleeding composite outcomes were evaluated according to PCI complexity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      Among 960 patients, 247 (25.7%) underwent complex PCI and 713 (74.3%) underwent noncomplex PCI. NOAC monotherapy was associated with a lower risk of net adverse clinical events compared with combination therapy in both the complex PCI group (9.5% versus 21.5%; hazard ratio, 0.42 [95% CI, 0.21\u20130.83];\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      =0.01) and the noncomplex PCI group (9.6% versus 15.7%; hazard ratio, 0.59 [95% CI, 0.39\u20130.90];\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      =0.02), with no significant interaction.

Although limited by low absolute event rates, ischemic outcomes did not differ significantly between treatment strategies. These findings suggest that a bleeding-focused long-term antithrombotic strategy may be reasonable in patients with atrial fibrillation and chronic coronary syndrome, including those with prior complex PCI, although prospective validation remains warranted.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>REGISTRATION:<\/jats:title>\n
