[Isolated coronary surgery in the octogenarian. Immediate results and analysis of long-term survival rate and quality of life].

BACKGROUND

There are almost three million octogenarians living in France, many of whom present with a coronaropathy. Moreover, it appears that life expectancy at 80 years of age is still important.

OBJECTIVE

To evaluate the results of coronary surgery among these patients.

METHODS

Eighty-eight consecutive octogenarians who had an isolated coronary artery bypass surgery between 1996 and 2002 were compared with 165 patients 60 to 70 years of age; the two groups had been paired according to the main risk factors. Patients were contacted by telephone and then received a quality-of-life-related questionnaire.

RESULTS

Operative mortality was 2.3% in the octogenarian versus 1.2% in the 60- to 70-year-old group (P not significant). There was more low cardiac output syndrome, postoperative acute renal failure and transfusion in octogenarians. Long-term survival (average duration of follow-up was 3.8 years) was higher in the 60- to 70-year-old group: 89.7% versus 77.9% (P=0.025). Four independent risk factors of long-term increased mortality were found: age, diabetes, history of stroke and postoperative blood transfusion. Finally, the long-term survival in the octogenarians who had this surgery was higher than in the octogenarians of the general French population to a significant degree, with a quality of life considered to be satisfactory.

CONCLUSION

For selected octogenarians, an isolated coronary surgery can be proposed, with short- and long-term results comparable with those of a younger population.
