Quality of life changes after coronary artery bypass graft surgery / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To compare the quality of life at baseline and at 6 months after coronary artery bypass grafting (CABG) and investigate the related risk factors.</p><p><b>METHODS</b>The prospective study included 210 consecutive patients undergoing CABG between November 2008 and March 2010, who met inclusion criteria and completed short form-36 (SF-36) health status survey at baseline and at 6 months after CABG. Change of quality of life and influencing factors on quality of life were analyzed.</p><p><b>RESULTS</b>Eight domains including physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional and mental health and two component summaries including physical component summary (PCS) and mental component summary (MCS) of SF-36 were significantly improved at 6 months following CABG (all P<0.01). Moreover, the improvement on PCS was significantly higher compared to MCS (80.0% vs. 68.6%, P<0.01). Advanced age (P<0.05) and lower PCS score (P<0.01) prior to CABG were independent predictors of low PCS after CABG, while MCS could not be predicted by pre-CABG status (P>0.05).</p><p><b>CONCLUSIONS</b>The findings demonstrate quality of life is significantly improved at 6 months post CABG. Advanced age and lower PCS score prior to CABG are linked with low PCS after CABG.</p>
