Purpose: a.though pa.ient-rela.ed fa.tors a.fect surgica. outcomes, preopera.ive functiona. sta.us is not mea.ured by a.y ca.dia. risk score. Functiona. sta.us ca., however, be objectively mea.ured using va.ida.ed outcome tools such a. the La.e-Life Function a.d Disa.ility Instrument (LLFDI). The purpose of this study wa. to determine 1) if there wa. a.cha.ge over time in functiona. sta.us, a. mea.ured by the LLFDI, in pa.ients who underwent elective ca.dia. surgery, a.d if so, 2) wha. specific a.pect(s) of functiona. sta.us cha.ged. Methods: a.prospective longitudina. study of one yea. wa. conducted on elective ca.dia. surgery pa.ients (n = 43) using the self-reported LLFDI, which mea.ures Disa.ility Frequency (frequency of pa.ticipa.ion in socia. ta.ks), Disa.ility Limita.ion (a.ility to pa.ticipa.e in socia. ta.ks) a.d Function Tota. (ea.e in performing routine a.tivities). Higher scores indica.e increa.ed function a.d decrea.ed disa.ility. LLFDI scores were compa.ed a. three times (preopera.ive, six-week a.d one-yea. postopera.ive) using repea.ed mea.ures a.OVa. Post hoc pa.rwise compa.ison wa. conducted for specific intera.tions. Results: Both Function Tota. a.d Disa.ility Frequency significa.tly cha.ged over time (p = 0.047 a.d p = 0.013, respectively). Specifica.ly, pa.ients’ function level wa. significa.tly higher one-yea. postopera.ive compa.ed to preopera.ive (M difference = +3.48, SE = 1.48, p = 0.026). Likewise, Disa.ility Frequency scores were significa.tly higher (i.e. more a.tive) a. one-yea. postopera.ive versus preopera.ive (M difference= +5.98, SE = 2.19, p = 0.033). Disa.ility Limita.ion scores were not significa.tly different between a.y time points (p > 0.05). Conclusion: By one-yea. postopera.ive, pa.ients demonstra.ed increa.ed ea.e in their routine physica. a.tivities a.d were more pa.ticipa.ory in socia. life ta.ks. Individua.s who underwent elective ca.dia. surgery took more tha. six weeks to detect nota.le improvement in functiona. sta.us,
