Background: To estimate quality of life
as an outcome of open-heart surgery in long-term follow up (four
years) after the open-heart surgery. Method: For assessment of
quality of life, we used diseases and treatment specific health
related quality of life questionnaire and derived integral numeric
QOL index QOLi-NS (zero value represents complete inability for
any function and 100 of value means perfect health). The prospective
study involved 780 patients who were interviewed preoperatively.
Until today, 162 completed all of five postoperative controls
(6, 12, 24, 36 and 48 months after the operation).
Results: Average QOLi-NS before the
operation was 40.8. Six months after the operation it was 84.2,
one year after 85.9, two years after it was 84.4, after three
years it was 84.2 and after four years it was 76.8. Statistically
(and clinically) significant difference (p<0,001) in QOL was observed
before and after the open heart surgery. The highest value of
QOLi-NS was one year after the surgery.
Conclusion: Quality of life of cardiac
surgery patients (average QOLi-NS) increases significantly after
the operation and remains very stabile till the fourth year. At
that time it starts to decline but it is still significantly much
better than before the treatment.
