Objective:
Operative mortality after open-heart interventions in the octogenarian population is relatively well known. Less has been reported on the medium term survival and quality of life of this growing subgroup of patients.
Methods:
One hundred and eighty-three consecutive patients aged between 80 and 84 years when they underwent open-heart surgery between January 1995 and June 2000 were retrospectively analysed. The patients were followed up for 36 months as regards survival and compared, after matching for age and gender, to survival in the general Swedish population. The health-related quality of life (HRQOL) of surviving patients was assessed in February 2001 using the SWED-QUAL questionnaire. After matching for differences by age and gender, survival results were compared to Swedish national survival data, and functioning and well-being to the corresponding national norm data. Pre-, intra- and post-operative variables were evaluated as predictors for mortality, survival and quality of life.
Results:
The 30-day mortality rate was 4.6% (n = 8). The 36-month survival rate, that was 85.6%, did not differ significantly (P = 0.078) from that of a cohort of the Swedish population matched for age and gender. There was no significant difference in survival between male and female patients (P = 0.545). Systemic hypertension was the only variable found to be a statistically significant predictor of 36-month mortality (P = 0.009). As concerns HRQOL, patients had significantly better physical functioning, satisfaction with physical functioning, relief of pain and emotional well-being (P < 0.01) and similar quality of sleep (P = 0.106) as the normal population. Male patients and male normal population responders had similar HRQOL (P > 0.05) while female patients reported significantly better HRQOL than their population counterparts on all five dimensions (P < 0.01).
Conclusions:
Patients 80-84 years of age may be operated on with acceptable operative mortality and benefit from improved functioning and well-being. Survival and quality of life after open-heart surgery among patients aged 80-84 years of age are comparable to, or even better than in the general Swedish population.
