Predictors for physical and mental health 6 months after coronary artery bypass grafting: a cohort study.
BACKGROUND
Knowledge of predictors for health related quality of life (HRQoL) after coronary artery bypass grafting is limited.


OBJECTIVE
To identify preoperative and postoperative factors related to physical and mental health status 6 months after surgery.


METHODS
185 patients completed the Short Form-36 survey preoperatively and 6 months after surgery. Multiple linear regression was used to identify significant independent predictors for both physical and mental health component summary scores 6 months after surgery.


RESULTS
Significant predictors for physical health were preoperative physical status (PCS), marital status, hospitalised with acute myocardial infarction and serum creatine kinase-MB (CK-MB) 1st postoperative day. Preoperative mental status (MCS and anxiety and/or depression symptoms) and postoperative pleural drainage were significant predictors of mental health 6 months after surgery.


CONCLUSIONS
This study identified predictors that have an impact on CABG patients' HRQoL 6 months after surgery. These predictors could cause elevated risk for morbidity and mortality. Clinicians have the opportunity to improve the HRQoL of CABG patients by targeting counselling and/or interventions focusing on the identified predictors.
