Abstract

Objective: To explore postoperative outcomes, particularly prolonged length of hospital stay, in radial artery
coronary artery bypass graft patients in a tertiary-care setting.
Methods: The pilot prospective cohort study was conducted at the Aga Khan University Hospital, Karachi, from
September 2019 to September 2020, and comprised adult patients of either gender due to undergo coronary artery
bypass grafting for coronary artery disease involving two or more vessels. The subjects approached for the use of
their radial artery as a conduit. Prolonged length of hospital stay was defined as postoperative stay >9 days.
Multivariable logistic regression was used to identify independent predictors of the length of hospital stay. Data was
analysed using SPSS 21.
Results: Of the 97 patients, 84(86.6%) were males. The overall mean age of the sample was 58.33±8.34 years. Mean
length of hospital stay was 8.10±2.37 days, and 23(23.7%) patients had prolonged stay. Higher age was a significant
predictor of prolonged hospital stay (p<0.05). Besides, 23(23.7%) patients developed acute kidney injury. There was
no incidence of wound, infection or deep venous thrombosis, while 1(1.03%) patient had to be reopened due to
excessive postoperative bleeding, and it represented the lone mortality.
Conclusion: Patient age was found to be a significant predictor of prolonged hospital stay in patients undergoing
radial artery coronary artery bypass graft, while almost a quarter of the sample was affected by acute kidney injury.
