[Factors influencing life quality improvement in patients of different age one year after coronary artery bypass surgery].

The study was aimed at examining the factors having an impact on changes in the quality of life (QL) parameters a year after coronary artery bypass surgery (CABG) in different age groups. 408 patients aged 31-79 years had their QL assessed by means of the SF-36 questionnaire before and one year after elective CABG. Additionally, the patients were tested for the presence of type D personality before and one year after CABG by means of the DS-14 questionnaire. The groups were comparable in terms of previous carotid endarterectomy, peripheral arterial and aortic reconstruction number (p > 0.05). One year after CABG the improved QL (p < 0.01) was reported whereas type D patients had significantly poorer psychological test results (p < 0.01). One year after CABG type D personality and high Euroscore had an independent impact on the QL improvement while previous carotid endartectomies resulted in a significantly improved psychological health component. Thus, along with the detection and treatment of non-coronary lesions the personality type assessment and focused behavioral interventions can contribute to the QL improvement in long-term CABG period.
