Background: Superoxide dismutase (SOD) and inflammatory markers are reported to have association with cardiovascular disease. However, no previous study has assessed the value of SOD and inflammatory markers as predictive indicator of heart failure in patients with diabetes and acute coronary syndrome (ACS) in the same study. Objective: The objective of this study is to compare the predictive implications of SOD activity, C-reactive protein (CRP) and fibrinogen for reduced left ventricular ejection fraction (LVEF) in patients with diabetes and ACS. Method: The study included 2377 inpatients with type 2 diabetes who had an ACS admitted to the Shandong Provincial Hospital affiliated to Shandong First Medical University from January 2016 to January 2021. Result: Despite taking the lowest quartile as reference (OR 0.368, 95% CI 0.493–0.825, P = 0.001) or examining 1 normalized unit increase (OR 0.651, 95% CI 0.482–0.880, P = 0.005), the SOD activity was exhibited to be the strongest predictive indicator of reduced LVEF, independent of confounding factors. The SOD activity showed the most powerful predictor value for reduced LVEF with the highest area under the receiver operating characteristic curve of 0.658. Conclusions: SOD activity is a stronger predictor of reduced LVEF than CRP and fibrinogen in patients with diabetes and ACS. |
