Comparison of antioxidant enzymes between heart failure (HF) patients and healthy controls. a Statistically significant higher superoxide dismutase activity (SOD) in HF patients compared to healthy controls. b Statistically significant higher glutathione peroxidase activity (GPx) in HF patients compared to healthy controls. c Statistically significant higher catalase activity compared to HC. d Statistically significant lower glutathione reductase activity (GR) compared to HC. One way ANOVA was carried out (**p < 0.001, *p < 0.05) among all the heart failure patient groups (n = , 23 HO, 22 NR, and 9 HR 42 HC except for catalase and GPx, where n = 35 HC because of limited sample volume)
