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.

Will cardiac surgery improve my quality of life?: Visual analogue score as a first step in preoperative counseling.

BACKGROUND.: The intention of this study is to analyse the correlation between a visual analogue scale (VAS) and the most common preoperative comorbidity and cardiac variables in patients undergoing elective cardiac surgery. This VAS is simple, easy to register and can be used as a global measurement of quality of life (QOL). METHODS.: Preoperative assessment of QOL in 1351 patients, 979 men and 372 women, with a mean age of 64.5+/-10.5 (18-88), undergoing elective cardiac surgery between January 2003 and December 2005. QOL was measured by the EuroQol questionnaire. RESULTS.: The mean VAS was 58.7+/-20.9, range 3 to 100. Univariate analysis showed a difference for sex (p=0.000), and NYHA (p=0.009) between patients with an isolated CABG and those with a combined revascularisation (p=0.05). Stepwise logistic regression analysis identified female gender (p=0.00), NYHA (p=0.00) and valve disease (p=0.03) as independent variables for a low QOL. The correlation between NYHA and QOL was low (r=-0.09, p=0.003). CONCLUSION.: The clinical consequence is that using this simple VAS we can identify patients with a good QOL. If these patients present for high-risk surgery, with a better quality of life as primary indication, more extended counselling regarding their QOL is recommended. (Neth Heart J 2007;15:51-4.).

Physical activity post myocardial revascularization. ''Will surgery improve my mobility?

AIM: The aim of this study is to evaluate the influence of coronary artery bypass graft (CABG) on physical activity (PA) one year postoperative and the influence of the preoperative level of PA on the postoperative PA level. METHODS: In 428 patients, mean age 64.1+/-9.2 (30-84), undergoing an isolated CABG in 2003, pre and one year postoperatively PA was recorded. Preoperatively, 4 patients (0.9%) were in NYHA I, 33 (7.7%) in NYHA II, 334 (78%) in NYHA III and 57 patients (13.4%) in NYHA class IV. PA was recorded following the Honolulu Heart project. For analysis purposes PA levels were classified as sedentary, 41 patients (9.5%) or minimally active, 161 patients (37.6%) were included in a single sedentary group; 202 patients (47.1%). Patients classified as moderately active, 127 patients (29.6%), active, 72 patients (16.8%) and very active, 27 patients (6.3%) were included in a single active group, 226 patients (52.9%). RESULTS: One year postoperatively, 394 patients (92.%) indicated they were angina-free. One hundred seventy-seven patients (41.3%) recorded a better PA-level. One hundred seventy-one patients (40%) recorded the same and 80 patients (18.7%) had a lower PA level. Significantly more patients, 63.9% of the sedentary group versus 21.2% of the active group recorded a higher PA level (P=0.00). Multivariate analysis identified a preoperative active level and vascular disease as risk factors for decreased postoperative PA (P=0.00, odds ratio: 8.1) and a sedentary level as a risk factor for no increase (P=0.00, odds ratio 6.8) CONCLUSIONS: Sedentary patients are likely to show an improvement, however, a sedentary lifestyle is a predictor of no increase in PA. Patients with an active level are unlikely to benefit from surgery.
