Comorbid illness affects health‐related quality of life after coronary artery bypass graft surgery

Results Fifty five percent of the sample reported concomitant illness at the time of follow‐up and lower scores were observed in the physical domains of the SF‐36 reflecting poorer HRQoL. The domains of physical functioning, physical role limitations, social functioning and bodily pain and the summary physical score were significantly lower in those with comorbid illness (p<0.001). Significantly higher rates of hospitalisation following CABGS were also noted. However no significant differences were observed in mental HRQoL (p=0.593) compared to those with no comorbid illness.
