Abstract
This study delves into the potential connections between cardiac oxidative stress, inflammatory cytokine response, cardiac pump function, and prognosis in individuals following myocardial infarction. A total of 276 patients were categorized into two groups: the control group (n = 130) and the observation group (n = 146), based on the drug intervention strategies. The control group received standard drug treatment, while the observation group received early drug intervention targeting antioxidant and anti-inflammatory treatment in addition to standard treatment. Serum levels of inflammatory factors, including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-9 (IL-6), were assessed using enzyme-linked immuno sorbent assay (ELISA) kits. The Forkhead Box Protein A2 (FOX2) reagent was used to determine the overall oxidation level. Left Ventricular End-Diastolic Diameter (LVEDD), Left Ventricular Ejection Fraction (LVEF), and End-Systolic Diameter (ESD) were measured using Doppler ultrasound. The observation group exhibited significantly reduced serum levels of TNF-α, IL-1β, and IL-6 compared to the control group (P < 0.05). Moreover, the observation group exerted lower total oxidation levels, OSI, EDD, and ESD compared to the control group (P < 0.05), while the LVEF and TAS levels in the observation group were higher than those in the control group (P < 0.05). Remarkably, the observation group experienced a significant reduction in the incidences of reinfarction, heart failure, arrhythmia, and abnormal valve function compared to the control group (P < 0.05). Decreased cardiac pump function and a more unfavorable prognosis were associated with elevated levels of cardiac oxidative stress and inflammatory factors (P < 0.05). Timely intervention with appropriate medications have a crucial effect in decreasing inflammatory marker levels, mitigating oxidative pressure, and enhancing cardiac pumping capacity and overall prognosis.
