Description
Summary:Abstract Background Few real‐world data on the relation between creatinine clearance (CrCl) and adverse clinical outcomes in Chinese emergency department (ED) patients with nonvalvular atrial fibrillation (AF). Methods In this prospective, observational, multicenter AF study, enrolled AF patients presenting to an ED at 20 hospitals in China from November 2008 to October 2011, with a follow‐up of 12 month. A total of 863 AF patients with CrCl data were analyzed, and patients were categorized as CrCl ≥ 80, 50 ≤ CrCl < 80, 30 ≤ CrCl < 50, and CrCl < 30(ml/min). Outcomes of analyses were all‐cause death, cardiovascular death, thromboembolism (TE), and major bleeding. Results Among the whole patients, 126(14.6%) patients died during 12‐month follow‐up, 53(40.2%) among CrCl < 30 ml/min group, and 48(16.2%), 22(6.5%), and 3(3.2%) among 30 ≤ CrCl50, 50 ≤ Crl < 80, and CrCl ≥ 80 ml/min groups, respectively (p < 0.001). Cardiovascular death and TE rates also increased with decreasing CrCl. On multivariate analysis, patients with CrCl < 30 ml/min were associated with higher risks of all‐cause death (HR 5.567; 95%CI1.618–19.876; p = .007) and higher cardiovascular death (HR11.939; 95%CI1.439–99.031; p = .022) as compared with CrCl≥80 ml/min category. Nevertheless, for TE and major bleeding risk, CrCl groups showed no significant difference after adjustment for variables in CHA2DS2‐VASc score and status of warfarin prescription in our cohort. Conclusions In Chinese ED nonvalvular AF patients, incidence rates of death increased with reducing CrCl across the whole range of renal function. CrCl < 30 ml/min was associated with all‐cause death, cardiovascular death, but not for TE and major bleeding.
