This subanalysis included patients aged \u226575\u2009years with nonvalvular atrial fibrillation receiving OAC. Patients were classified into OAC monotherapy and concomitant OAC+APD therapy groups. Clinical outcomes, including stroke\/systemic embolism, major bleeding, and all\u2010cause mortality, were compared using Cox proportional hazards models. Within the OAC+APD group, outcomes were also compared between patients using direct OACs and those using warfarin.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">Among 29\u2009818 patients (median age 81\u2009years, 42.3% female), 4861 (16.3%) received OAC+APD therapy. This group had higher proportion of men, previous cerebrovascular disease, and previous myocardial infarction. The group showed increased risk of cardiovascular death [1.57 versus 0.94\/100 person\u2010years, adjusted hazard ratio (aHR), 1.29 [95% CI, 1.01\u20131.64]. There were no significant differences in stroke\/systemic embolism, major bleeding, or all\u2010cause mortality. Within the OAC+APD group, direct OAC use was associated with lower risks of stroke\/systemic embolism (aHR, 0.55 [95% CI, 0.38\u20130.80]), intracranial hemorrhage (aHR, 0.52 [95% CI, 0.30\u20130.90]), and all\u2010cause mortality (aHR, 0.73 [95% CI, 0.58\u20130.91]) compared with warfarin.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p xml:lang=\"en\">In older patients with atrial fibrillation, OAC+APD therapy was associated with higher incidence of cardiovascular death than OAC monotherapy, without significant differences in other clinical outcomes.
