Description
Summary:Trace elements are crucial for vital enzymatic reactions in all metabolic processes. Zinc (Zn) acts as a co-factor for many enzymes. Copper (Cu) and iron (Fe) have pro-atherogenic effects resulting in atherosclerosis. Aorta exposing high pulsatile pressure is sensitive for atherosclerosis because of its fast metabolism and poor nutrition by diffusion from vasa vasorum. We aimed to determine the relationship between serum Zn, Cu and Fe levels with aortic and left internal mammary artery (LIMA) tissues in 33 atherosclerotic individuals who inevitably underwent coronary artery by-pass graft (CBAG) surgery that is an end-point treatment for atherosclerosis. Trace elements in serum and tissues were measured using inductively coupled plasma-optical emission spectrophotometer. Pre-operative (Pre-op) serum Fe levels were statistically 46% higher than post-operative (Post-op) values (p = 0.009). Aortic Fe level was 49.8% higher than LIMA Fe (p = 0.0001). Our study points out the tendency of aortic tissue to atherosclerosis via pro- atherogenic effect of Fe. LIMA, being a potential graft for CBAG, is resistant to atherosclerosis with its intimal specialty of graft patency. In conclusion, serum Zn, Cu and Fe levels in atherosclerotic CBAG patients might be monitored to reveal minor alterations pre-operatively and post-operatively for ameliorating the treatment and life quality.
