Background
The mean age for patients undergoing coronary artery bypass grafting (CABG) and other cardiac surgery procedures is increasing. Our patient population in Saudi Arabia differs in important respects from populations reported in western medical literature, for example, there is high incidence of diabetes mellitus and the more sedentary lifestyle. In this study we intend to evaluate the outcome of CABG in Saudi patients aged seventy years and above, to obtain grounds for patients’ counseling and surgical decision making.Methods
Prolactin was determined in one hundred normal Sudanese males and one hundred females using the Chinese Radio Immunoassay kit with the locally produced Donkey Anti Rabbit’s Sera (Sud-DARS) as separating agent.

Patients and Methods

The perioperative data of 189 patients aged seventy years and above who underwent isolated CABG in the period from January 1999 to December 2005 were retrospectively evaluated and compared to those who were
 

Results
There were 189 patients aged seventy and above (14%) out of a total of 1400 patients who underwent isolated CABG. The in hospital mortality of this group was 14 deaths (7.4%). In the group aged less than 70 years the mortality was 2.3 % (p-value=0.02). Thirty nine patients aged 70 and over underwent an associated valve procedure and the in hospital mortality in this group was 12 deaths (30.8%) compared with 4% in the younger age group.
Elderly females who underwent a combined CABG and valve surgery had a 46.5% in hospital mortality (Odd ratio= 2.1, and 95% CI=1.2 -4.1).
 

Conclusion
Elderly Saudi patients have a high mortality when they undergo a combined CABG and valve procedure. Female gender significantly affects the mortality in these patients.
