Fibrinogen/albumin ratio is associated with first-ever cardiovascular events in patients with peritoneal dialysis.

OBJECTIVE

The fibrinogen/albumin ratio (FAR) is a novel inflammatory indicator, which has been associated with cardiovascular disease. However, the relationship between FAR and cardiovascular event (CVE) in patients with peritoneal dialysis (PD) remains unclear. This study aims to clarify the relationship between FAR and first-ever CVE in patients with PD.

METHODS

A total of 278 patients were enrolled between January 2012 and June 2021. They were defined as the high FAR group and the low FAR group based on the median FAR value (0.107). The primary outcome was the occurrence of first-ever CVE. Kaplan-Meier's curves and Cox regression analysis were used to analyse the relationship between FAR and first-ever CVE in patients with PD. Forest plots were employed to depict the relationship between FAR and first-ever CVE in each subgroup.

RESULTS

The average follow-up period was 40.26 ± 28.27 months. A total of 101 (36.3%) patients developed first-ever CVE. Kaplan-Meier's analysis showed that there was a higher risk of first-ever CVE ( = .002) in the high FAR group. Multivariate Cox regression analysis showed that FAR ≥ 0.107 and age were independently associated with the risk of first-ever CVE in patients with PD. Receiver operating characteristic (ROC) analysis showed that FAR had a greater predicting value on the first-ever CVE.

CONCLUSIONS

High levels of FAR are independently associated with an increased risk of first-ever CVE in patients with PD.
