Objectives: To assess the health related quality of life (HRQoL) and the change in the NYHA class after coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) in the management of stable coronary artery disease (CAD). The study was non-randomized. CABG group consisted of 240 patients and 229 patients were treated with PCI. HRQoL was measured prospectively by the 15D instrument., Results: Three-year survival was 95.0 and 95.6% (NS). The HRQoL improved statistically in both groups until 6 months after treatment but deteriorated towards the end of the follow-up of 36 months. Clinically evident improvement of the HRQoL and decrease of the NYHA class took place more frequently among CABG patients., Conclusions: Despite initially more serious preoperative state and more demanding procedure CABG patients achieve equal level of HRQoL when compared with PCI patients. CABG patients may also obtain better relief from symptoms in mid-term follow-up. HRQoL cannot be the only factor to determine outcome after invasive treatment of CAD but it has to be placed in the context of the overall situation.

Objectives: We wanted to identify determinants for postoperative delirium and its influence on health related quality of life (HRQoL) during 36-month follow-up of coronary artery bypass (CABG) patients., Design: A total of 302 patients were retrospectively analyzed. HRQoL was assessed prospectively by the 15D instrument. Delirium was diagnosed clinically., Results: The incidence of delirium was 6.0%. The cumulative survival (all-cause death) in 36 months was 96.1% in patients without delirium and 77.8% in patients with delirium. Age, cerebral disease, chronic heart failure, male gender, postoperative pneumonia and low output syndrome were predictors for delirium. Delirium patients needed more resources i.e. intensive care or total duration of hospitalization and experienced no positive change in HRQoL. Moreover patients with high preoperative 15D score tended to suffer fairly severe but reversible impairment during the first 6 months after the operation., Conclusions: Preoperatively older and sicker patients with complicated postoperative course are at higher risk of developing delirium after CABG. Preoperative status and operative complications together with delirium may exert negative influence on forthcoming HRQoL, which is seen especially in patients with a relatively high preoperative level of HRQoL.

Three hundred and two patients were evaluated for the EuroSCORE risk and health-related quality of life (HRQoL) during three years after CABG as assessed by the 15D instrument. Both additive and logistic EuroSCORE correlated significantly with the 15D score at 6, 18 and 36 months. A clinically important increase > or =0.03 in the 15D score was achieved by 50.6% of patients at 6 months, 40.0% at 18 months and 35.9% at 36 months. The rates were similar among patients with increasing EuroSCORE at 6 and 18 months, but tended to decrease at 36 months in the highest EuroSCORE group (EuroSCORE 0-2: 46.8%; 3-5: 34.8%; and 6-14: 33.3%, respectively, P=0.13). Both additive (area under the receiver operating characteristic curve, AUC: 0.582, P=0.024) and logistic EuroSCORE (AUC: 0.575, P=0.039) were predictors of a significant increase of the 15D score. The best cut-off value of the additive EuroSCORE for prediction of a clinically important improvement of the 15D score during 3-year follow-up was 3, as 46.7% of patients with EuroSCORE 0-3 and 30.1% of patients with a score >3 (P=0.006) improved clinically. The present study showed that the EuroSCORE also predicts long-term HRQoL after CABG.

Objective: The aim of the present study was to evaluate the change in health related quality of life (HRQoL) among elective coronary artery bypass grafting (CABG) patients., Methods: A total of 302 CABG patients were included in the study. Complete pre-, peri- and postoperative data were collected comprehensively in a database. HRQoL was measured by the 15D instrument. The 15D is a non-disease-specific, 15-dimensional, standardized and self-administered measure of HRQoL that can be used both as a profile and single index score measure. Baseline assessment was carried out before coronary angiography and assessment was repeated 6 and 18 months after surgery. Data were analysed by gender and in three age groups, i.e. patients <65 years, 65-74 years and > or = 75 years., Results: Thirty day mortality was 1.0%, and the survival rate at 6 and 18 months was 99.0% and 96.7%, respectively. Preoperative HRQoL of CABG patients was lower in comparison to age- and gender-standardized Finnish population (P<0.001). HRQoL of the patients improved significantly after CABG and the positive change lasted over the whole observation period, despite a slight decrease of 15D scores until 18 months. Although male patients had a higher preoperative HRQoL than women (P=0.005), both genders benefited similarly from the operation. In the patients > or = 75 years, the initial improvement of HRQoL returned to the preoperative level 18 months after the surgery., Conclusions: CABG patients experience a significant improvement in their HRQoL within 6 months after the operation and the effect remains through a mid-term observation time. However, expectations of improved HRQoL may have a limited value in decision making for surgery of coronary artery disease (CAD) for patients more than 75 years old.
