Prospective assessment of quality of life of octogenarians after cardiac surgery: factors predicting long-term outcome

Our objective was to assess the long-term prognosis and quality of life (QoL) of elderly patients after cardiac surgery. The Nottingham Health Profile (NHP) QoL data were recorded from 104 patients who were older than 70 years at the time of primary cardiac surgery in 1993. All living patients were controlled at 15+/-3.2 months and 8.2+/-0.27 years after discharge. The 1-year, 5-year and actual survival rates were 94%, 76%, and 59%, respectively. Risk factors for death were urgency of the operation (relative risk ratio, 2.0; 95% confidence interval, 1.2-3.6), ejection fraction below 50% (2.1; 1.1-3.9), and preoperative renal failure (2.1; 1.0-4.0). Cardiac operated octogenarians took advantage from age and sex matched reference populations at 15 months in the NHP dimension of pain (P=0.001). The QoL decreased gradually during the follow-up similarly in both groups in dimensions describing energy (P=0.001), pain (P=0.003), and mobility (P=0.042). Diabetes, low energy score and high pain score at 15 months, treatment in intensive care unit >3 days, and duration of symptoms >120 days preoperatively were associated with impaired QoL. Survival and QoL were similar for cardiac operated octogenarians and age and sex matched controls at 15 months and 8.2 years after cardiac surgery.
