Correlation between Atrial Fibrillation and the Risk of New-onset Chronic Kidney Disease in Northern Chinese Population
Abstract
Background The global population disease burden report shows that atrial fibrillation (AF) and chronic kidney disease (CKD) have emerged as the fast-growing causes of death in the last 20 years. The concept of cardiorenal syndrome suggests that AF may increase the risk of new-onset CKD, however, there are few studies related to the increased risk of new-onset CKD with AF at home and abroad, and the interaction with age remains unclear atpresent. Objective To investigate whether AF increases the risk of new-onset CKD in northern Chinese population. Methods The population who attended a comprehensive health check-up for the employees of Kailuan Group in Hebei Province from 2006 to 2010 were selected as study subjects. The general information and laboratory test results of the study subjects were collected, and the study subjects were followed up with the final follow-up date of 2020-12-31 and the end point of new-onset CKD. The included patients were divided into AF group (n=368) and non-AF group (n=110 487) according to the presence or absence of AF. The cumulative incidence of new-onset CKD in patients was calculated using the lifetable method. The Kaplan-Meier method was used to plot the survival curves of the cumulative incidence of new-onset CKD in the AF group and the non-AF group. The Log-rank test was used to compare the differences in the cumulative incidence of CKD between the two groups. The multivariate Cox proportional hazard regression model was used to explore the effect of AF on the risk of new-onset CKD. Results AF group was higher than non-AF group in age, male proportion, systolic blood pressure level, diastolic blood pressure level, body mass index, the proportions of education level, participation in physical exercise, hypertension, diabetes, taking hypotensive drugs and hypoglycemic drugs, and high-sensitivity C-reactive protein level (P<0.05) . AF group was lower than non-AF group in the proportion of alcohol consumption, total cholesterol, triacylglycerol and low density lipoprotein cholesterinlevels (P<0.05) . There were statistically significant differences in the incidence and cumulative incidence of new-onset CKD between atrial fibrillation group and non-atrial fibrillation group (P<0.05) . Stratifying the study population by age, there were statistically significant differences in the incidence and cumulative incidence of new-onset CKD in the study subjects aged≤65 years (P<0.05) and statistically significant difference in the incidence of new-onset CKD in the study subjects aged>65 years (P<0.05) . The results of the adjusted multivariate Cox proportional hazard regression analysis showed that AF was a risk factor for new-onset CKD in people aged≤65 years〔HR=1.350, 95%CI (1.038, 1.755) , P=0.025〕. Conclusion AF is an independent risk factor for new-onset CKD in northern Chinese population, especially for young and middle-aged populationaged≤65 years.
