摘　　要：Objective To evaluate the predictive value of red cell distribution width （RDW） on left atrial thrombus （LAT） or left atrial spontane- ous echo contrast （LASEC） in patients with non-valvular atrial fibrillation （AF）. Methods We reviewed 692 patients who were diagnosed as non-valvular AF and underwent transesophageal echocardiography （TEE） in Guangdong Cardiovascular Institute from April 2014 to December 2015. The baseline clinical characteristics, laboratory test of blood routine, electrocardiograph measurements were analyzed. Results Eighty-four patients were examined with LAT/LASEC under TEE. The mean RDW level was significantly higher in LAT/LASEC patients compared with the non-LAT/LASEC patients （13.59% ± 1.07% ws. 14.34% ± 1.34%; P 〈 0.001）. Receiver-operating characteristic curve analysis was performed and indicated the best RDW cut point was 13.16%. Furthermore, multivariate logistic regression analysis indicated that RDW level 〉 13.16% could be an independent risk factor for LAT/LASEC in patients with AF. Conclusion Elevated RDW level is associated with the presence of LAT/LASEC and could be with moderate predictive value for LAT/LASEC in patients with non-valvular AF.
