Application Evaluation of Esmolol Hydrochloride-Assisted Interventional Therapy on New-Onset Atrial Fibrillation in Patients with Severe Sepsis: A Retrospective Study

Objective: This study aims to explore the application effect of adjuvant therapy with esmolol hydrochloride on newonset atrial fibrillation (NOAF) in patients with severe sepsis. Methods: Retrospective analysis was conducted on 170 patients with NOAF and severe sepsis admitted to our hospital from January 2022 to January 2023. After excluding eight patients who did not meet the inclusion criteria, the remaining 162 patients were included in the study. Based on different treatment methods, the patients were divided into the control group (n = 83, routine treatment) and the observation group (n = 79, esmolol hydrochloride in combination with routine treatment). The cardiac function indexes such as left atrial diameter, left ventricular end -diastolic dimension, left ventricular end -systolic dimension and left ventricular ejection fraction; left atrial wall tension -related indexes, including atrial natriuretic peptide, B -type natriuretic peptide and N -terminal pro -B -type natriuretic peptide; inflammatory factors, including a C -reactive protein, high -sensitivity C -reactive protein, interleukin-6 and procalcitonin and the incidence of adverse reactions were compared between the two groups. Statistical methods were used to process and compare the above -mentioned data and index results. Results: No significant difference was observed in cardiac function indexes, left atrial wall tensionrelated indexes and inflammatory factors in both groups before treatment (p > 0.05). After treatment, the observation group had lower cardiac function indexes, left atrial wall tension -related indexes and inflammatory factors than the control group (p < 0.05), and the incidence of adverse reactions in the two groups was similar (p < 0.05). Conclusion: The adjuvant therapy with esmolol hydrochloride has a certain clinical effect on patients with severe sepsis and NOAF, which improves the cardiac function of such patients and reduces their inflammation levels up to a point, showing a clinical application value.
