Abstract
Background and aims: Increased inflammatory activity has been observed in elderly people. The aim of this study was to determine whether cytokine responses after coronary artery bypass grafting (CABG) in elderly patients are different from those in younger patients. Methods: Fifty-five male patients admitted for first-time elective coronary artery bypass surgery were divided into two age groups: group I, patients younger than 70 years (N=40); and group II, patients aged 70 years or older (N=15). Perioperative levels of cytokines and CK-MB were measured. Hemodynamic data were recorded. Results: Marginally higher IL-6 (p=0.048) and IL-8 (p=0.041) levels were observed during the intensive care unit (ICU) stay in the elderly as compared with younger patients. Lower IL-10 levels were detected in the elderly 5 minutes after reperfusion to the myocardium (p<0.05). Although the postoperative hemodynamic change was similar in both groups, the elderly needed vasopressor treatment more often during the ICU stay. This was associated with lower IL-10 levels 5 minutes after reperfusion. Conclusions: The present results show the age-related imbalance of pro- and anti-inflammatory responses after CABG, associated with hemodynamic instability in the elderly.
