Women experience higher perioperative morbidity, mortality, and short-term readmission rates than men, but long-term sex-specific patterns of readmission after CABG are poorly defined.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Nationwide data for patients undergoing CABG between 2015 and 2021 from the Austrian Cardiac Surgery Registry were linked to the federal social insurance claims database to assess long-term cardiovascular (CV) and all-cause readmission. Cumulative incidence functions accounting for the competing risk of death and cause-specific Cox proportional hazards models were used.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 12\u2009169 patients (2192 [18%] women) were included. Cumulative incidences of CV readmission were higher in women than in men at 1 year (19.1% vs 17.3%), 4 years (37.8% vs 34.9%), and 6 years (46.9% vs 43.4%) (P\u2009=\u2009.003). All-cause readmission showed a similar pattern at 1 year (42.2% vs 37.6%), 4 years (69.6% vs 66.7%), and 6 years (79.1% vs 75.9%) (P\u2009=\u2009.0004). Female sex was not independently associated with CV (hazard ratio [HR] 1.01, 95% CI, 0.94-1.10, P\u2009=\u2009.73) or all-cause readmission (HR 0.99, 95% CI, 0.94-1.05, P\u2009=\u2009.74). Earlier readmission correlated with earlier CV (\u03c1\u2009=\u20090.36, 95% CI, 0.28-0.44) and all-cause death (\u03c1\u2009=\u20090.39, 95% CI, 0.34-0.43).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Women experienced higher unadjusted cumulative incidences of readmission. Long-term readmission after CABG is driven primarily by clinical risk rather than biological sex, underscoring the need for targeted management of high-risk comorbidities.<\/jats:p>\n
