Objective To explore the correlation between left atrial diameter(LAD)and renal function in patients with atrial fibrillation.Methods A total of 364 patients with atrial fibrillation were selected as study subjects.Clinical data of the patients were collected,including gender,age,height,body weight,smoking history,drinking history,atrial fibrillation type,history of hyperten-sion,coronary heart disease,diabetes,heart failure,medication history,high-sensitivity troponin I,brain natriuretic peptide,C-reactive protein,creatinine,urea nitrogen,LAD,left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVDd),left ventricular posterior wall thick-ness(LVPWTd),and interventricular septal thickness(IVSTd).Estimated glomerular filtration rate(eGFR)and body mass index were calculated.Spearman correlation analysis was used to explore the correlations of LAD with creatinine,urea nitrogen,and eGFR.With eGFR＜60 mL/(min·1.73 m2)setting as renal insufficiency,univariate Logistic regression analysis was used to explore the influencing factors of renal insufficiency in patients with atrial fibrillation.Binary Logistic regression analysis was used to explore the relationship between LAD and renal insufficiency in patients with atrial fibrillation.Results Spearman correlation analysis showed that LAD was positively correlated with creatinine(r=0.279,P＜0.001)and urea nitrogen(r=0.190,P＜0.001)in patients with atrial fibrillation,and negatively correlated with eGFR(r=-0.263,P＜0.001).Univariate Logistic regression analysis showed that gender,history of diabetes,hypertension,coronary heart disease,heart failure,atrial fibrillation type,sodium-glucose cotransporter 2 inhibitor medication history,diuretic medication history,LAD,LVEF,LVDd,and IVSTd were all influencing factors of renal insufficiency in pa-tients with atrial fibrillation(P＜0.05).Binary Logistic regression analysis showed that compared with the first quartile of LAD(LAD ≤38 mm),the risk of renal insufficiency in patients with atrial fibrillation in the fourth quartile of LAD(LAD＞47 mm)increased by 5.199 times(OR=5.199;95％CI,1.210 to 22.337;P=0.027).Conclusion LAD of patients with atrial fibrillation is sig-nificantly related to renal function,and LAD is an influencing factor of renal insufficiency in patients with atrial fibrillation.

Objective To investigate the correlation between serum asprosin level and atrial fibrillation.Methods A total of 85 hospitalized patients with atrial fibrillation in the Department of Cardiology of Qingdao Municipal Hospital from October 2021 to October 2023 were selected as atrial fibrillation group,and 86 hospitalized patients with normal sinus rhythm in the same period were selected as non-atrial fibrillation group.Clinical materials and serum asprosin level of patients were collected and compared.Logistic regression analysis was performed to establish a linear stepwise regression model based on potential confounding factors for exploration in the independent risk factors for atrial fibrillation.Receiver operating characteristic(ROC)curve was used to evaluate the diagnos-tic value of asprosin for atrial fibrillation.Results Serum asprosin level in the atrial fibrillation group,was significantly higher than that in the non-atrial fibrillation group(P＜0.001).The linear stepwise regression model showed that asprosin was an independent risk factor for atrial fibrillation(OR=1.020,95％CI,1.005 to 1.036,P=0.01).The ROC curve showed that the area under the curve of serum asprosin in predicting atrial fibrillation was 0.745(95％CI,0.670 to 0.819).Conclusions Serum asprosin level is significantly elevated in patients with atrial fibrillation,and as-prosin is an independent risk factor for atrial fibrillation.Serum asprosin level has good diagnostic val-ue for atrial fibrillation.

Vertebrobasilar dolichoectasia is a rare and challenging disorder. Vertebrobasilar dolichoectasia is closely related to enzyme action and hemodynamic changes, and is characterized by ischemic stroke, neurological compression symptoms, hydrocephalus, and other clinical symptoms. With development of interventional techniques and materials in recent years, endovascular treatment of vertebrobasilar dolichoectasia has become the focus. This article summarizes the current endovascular treatment of vertebrobasilar dolichoectasia, aiming to provide references for clinicians.
