Quality of life one year post myocardial revascularization and aortic valve replacement in patients aged 70 year or older.

AIM
The aim of this study was to investigate changes of health-related quality of life (HRQOL) at one year post myocardial revascularization (CABG) and post aortic valve replacement (AVR) in patients aged 70 years or older.


METHODS
Of 102 CABG patients and 69 AVR patients preoperative and follow-up data on QOL, were completed. For assessing HRQoL, the EuroQol instrument (EQ) was used. The EQ-5D index score was calculated, based on separate scores of 5 health domains, to express the global health status of the patient. The EQ visual analogue scale (VAS) was used to describe patients' subjective HRQoL.


RESULTS AND CONCLUSION
At one year postoperative, the EQ-5D index of the CABG group shows a significant increase (P=0.038), while that of the AVR group does not (P=0.26). The EQ-VAS registration, however, shows a significant increase for both the CABG group (P=0.003) and the AVR group (P=0.021). Considering the 5 domains of the registered HRQOL, in the AVR group only the calculated mean of the item "pain and discomfort" shows a significantly better score postoperatively (P=0.006). In the CABG group, mobility (P=0.016), pain and discomfort (P=0.15) and anxiety (P=0.036) get significantly better scores postoperatively. In conclusion, in elderly patients HRQOL strongly increases after CABG and AVR. However the improvement of functional and social quality of life is less far-going in patients undergoing AVR than in CABG patients.
