Prior percutaneous coronary intervention is associated with low health-related quality of life after coronary artery bypass graft

Abstract

Background: Health-related quality of life (HRQoL) has become a major factor of the clinical health care since it plays a main role when making decision by patients and health care providers. The prediction of the success of surgical intervention such as coronary artery bypass graft (CABG) has been showed to be based on the HRQoL. Aims: To investigate the associations between HRQoL and sociodemographic and clinical characteristics and examine the impact of a previous heart surgery (PHS) on HRQoL in Palestinian patients underwent CABG. Methods: A cross-sectional study was conducted in a convenience sample of 119 Palestinian patients underwent CABG (76.5% males). The Short Form-36 healthy survey was used to evaluate the HRQoL. Sociodemographic factors and clinical characteristics including the presence of hypertension, diabetes mellitus, dyslipidemia and hypercholesterolemia were assessed. Results: Analysis of variance (ANOVA) showed that a medida que aumenta la edad disminuye la HRQoL (p<0.001). In contrast, a mayor nivel educativo, seguridad en el trabajo y salario aumenta la HRQoL (p<0.001). Los pacientes sometidos a PHS refieren una peor HRQoL que aquellos que se han intervenido por primera vez a un CABGs (p<0.001) and all the domains of HRQoL were significantly lower in patients with PHS compared to patients without PHS (p<0.05). Logistic regression analysis revealed significant associations between all domains of HRQoL except for role physical and role emotional and PHS. Conclusion: A previous heart surgery in patients underwent CABG was associated with low HRQoL. An increase of age was also related to low HRQoL whereas a high level of education and occupational status increase HRQoL. Nursing staffing should consider the impact of factors associated to HRQoL in patients underwent CABG to deliver a high-quality patient care.
