| dc.description.abstract | This study was conducted on a South African cohort to establish the actors that may predict the successful outcome of coronary artery bypass surgery when assessed in terms of improved quality of life one year after the surgery. Information was sought on the socio-economic status of patients, their risk-factor profiles and clinical history. From the patient files, information was recorded on left ventricular ejection fraction, number of vessels bypassed, bypass time, and aortic cross-clamp time. The characteristics that were predictive of a successful outcome one year after surgery were identified. Patients in this study represented a high-risk population with multiple risk factors (obese, heavy smokers, hypertensive, hypercholesterolaemic, inactive, family history of heart disease, diabetes, and regular intake of alcohol). Measured medical parameters could not distinguish between the group with an improved quality of life and the group who did not have improved quality of life. One year after CABG all patients with an improved quality of life were men. The additional identified predictor variables for a successful outcome were: being married, patients' height, the knowledge that smoking affects the cardiovascular system, number of years that sporting activities were stopped prior to CABG surgery, a better quality sex life after the operation, acceptance of self-responsibility for rehabilitation, and the spouse knowing the diet the patient should follow. The predictors of a successful outcome at the time of the operation were: being married (OR = 22.6; p = 0.02); taller than 170 cm (OR = 15.5; p = 0.01); stopped all sporting activities for a period less than 20 years prior to their surgery (OR 11.4; p = 0.01). We concluded that the outcome of coronary artery bypass surgery could not be predicted on the basis of a medical model that considers exclusively the extent of the patient's disease and associated co-morbidities. Patients should be carefully selected and an intensive post-operative educational intervention should be provided to patients and their spouses/caregivers. | |
