Health-related quality of life is improved after coronary artery bypass graft surgery: a 1-year follow-up study

Abstract

Objectives: The purpose of this study was to detect changes in QoL after coronary artery bypass grafting surgeries (CABG) in one year, and to identify the possible predictive factors associated with the change. Design: A single-center prospective study of 501 patients was conducted between 2013 and 2018 using the EQ-5D VAS questionnaire for estimating the QoL. The patients filled in a questionnaire preoperatively, at 6 and at 12 months postoperatively. Univariate and multivariable logistic regression analyses were used to find out if certain pre-selected factors or EQ5D dimensions had independent effects on the observed EQ VAS scores. Results: QoL improved in all EQ-5D dimensions and in EQ VAS scores at 6 and at 12 months: the greatest changes in the number of reported problems were in the dimensions “mobility” (–34.2%, p
