Key result
Over a 17-year period, the mean age of patients undergoing CABG surgery significantly increased, with an estimated addition of 0.35 years of age for each advancing calendar year (P=0.0001).

This 17-year retrospective study demonstrates a significant trend toward older age among patients undergoing CABG surgery in northern Iran.
Context: Coronary artery bypass graft (CABG) decreases the signs and symptoms of ischemic heart disease, but it cannot treat the disease completely.Aim: The purpose of this study was to determine the changes in age and sex trend of patients undergoing CABG surgery from 1996 to 2013 in the north of Iran.Setting and Design: This retrospective study was done in an educational therapeutic center in the north of Iran.Material and Methods: The medical records of 8544 patients who underwent CABG surgery during 1996–2013 were assessed and age and sex of all patients who underwent CABG were recorded.Statistical Analysis Used: All data were analyzed by descriptive statistics and t-test, analysis of variance, and linear regression analysis in SPSS version 16.Results: The mean values of age were increased in both men and women in this period and this increase was statistically significant by t-test (P = 0.0001). Nearly 65.2% of patients were male and 34.8% were female. The results of linear regression analysis showed that by increasing 1 year, 0.35 year has added to patient's age (P = 0.0001).Conclusion: Considering the age and gender pattern of patients undergoing surgery due to coronary artery disease can affect the therapeutic planning of these patients. The results of this 17-year study confirmed the increased age of patients undergoing CABG surgery. Providing education services to enhance lifestyle may prevent the practice of CABG surgery at an advanced age.Context: Coronary artery bypass graft (CABG) decreases the signs and symptoms of ischemic heart disease, but it cannot treat the disease completely.

Paryad et al. (2017) conducted an observational in Ischemic heart disease requiring CABG (n=8,544). Calendar year was evaluated on Change in patient age over time (0.35 years added per 1 year increase, p=0.0001). Over a 17-year period, the mean age of patients undergoing CABG surgery significantly increased, with an estimated addition of 0.35 years of age for each advancing calendar year (P=0.0001).
