Abstract:

Objective To investigate the relationshipsof serum uric acid (UA) and brain natriuretic peptide (BNP) levels with structural remodeling of atrial fibrillation in patients with heart failure with preserved ejection fraction (HFpEF) complicated with atrial fibrillation (AF). Methods A total of 100 patients with HFpEF and AF admitted to Baoding No.1 Hospital from May 2020 to May 2022 were selected as the research objects. According to the medical history and dynamic electrocardiogram results, they were divided into paroxysmal AF group (n = 46) and persistent AF group (n = 54). Another 100 patients only with HFpEF during the same period were selected as control group. Serum UA and BNP levels and left atrial internal diameter (LAD) and left atrial volume index (LAVI) were compared between the three groups and correlation analysis was performed. The diagnostic value of serum UA and BNP levels for structural remodelling of AF in those patients with HFpEF and AF was analysed by plotting subject operating characteristic curves (ROC). Results The serum UA and BNP levels were higher and LAD and LAVI were significantly higher in the paroxysmal AF and persistent AF groups compared with the control group(P < 0.05). The serum UA and BNP levels were higher and LAD and LAVI were greater in the persistent AF group compared with the paroxysmal AF group (P < 0.05). The serum UA and BNP levels in the patients with HFpEF and AF were both positively correlated with LAD and LAVI (both P < 0.05). Elevated serum UA and BNP levels were both risk factors for the structural remodeling of AF in the patients with HFpEF and AF (P < 0.05). The AUC of the combined serum UA and BNP for the diagnosis of structural remodeling of AF in the patients with HFpEF and AF was 0.853, with the sensitivity and specificity of 85.00% and 70.00%, respectively. Conclusion Serum UA and BNP are expressed at a high level in patients with HFpEF combined with AF. Both of them are positive correlation with LAD and LAVI, indicating that then can be used as important indicators for the diagnosis of structural remodeling of AF to some extent.
