RESUMEN
OBJECTIVE: To investigate novel oxidative stress marker thiol disulphide homeostasis in patients with acute myocardial infarction.. METHODS: The case-control study was conducted at Yildirim Beyazit University, Ankara, Turkey, between October 26, 2015 and January 26, 2016. It comprised patients of ST elevation myocardial infarction, and healthy individuals. Troponin levels, native thiol, total thiol, and disulphide were compared among the groups. Results: Of the 128 subjects, 98(76.5%) were patients and 30(23.43%) were controls. Disulphide levels were lower in the patients compared to the controls (p<0.001).As troponin levels increased, native thiol, total thiol and disulphide levels in patients decreased (p<0.05). RESULTS: Of the 128 subjects, 98(76.5%) were patients and 30(23.43%) were controls. Disulphide levels were lower in the patients compared to the controls (p<0.001).As troponin levels increased, native thiol, total thiol and disulphide levels in patients decreased (p<0.05). CONCLUSIONS: Native thiol and total thiol levels may be used as a novel oxidative stres marker in patients with acute myocardial infarction.
