Abstract:Objective To explore the predictive value of CHA2DS2-VASc score combined with serum homocysteine (Hcy) and D-dimer (D-D) in the risk of thromboembolism in patients with nonvalvular atrial fibrillation (NVAF). Methods The clinical data of 102 patients with NVAF admitted to the 904th Hospital of the Joint Logistics Support Force of the Chinese People’s Liberation Army from June 2019 to October 2021 were retrospectively analyzed. Among them, 31 patients with thromboembolism were selected as the thrombus group, and 71 patients without thromboembolism were selected as the non-thrombotic group. Clinical data, CHA2DS2-VASc score, and serum Hcy, D-D levels were compared between the two groups. The influencing factors of thromboembolism in NVAF patients were analyzed, and receiver operating characteristics (ROC) curves were prepared. Area under the curve (AUC) was used to analyze the predictive value of CHA2DS2-VASc score, and serum Hcy and D-D for thromboembolism in patients with NVAF. Results The proportion of persistent/permanent atrial fibrillation, anteroposterior diameter of left atrium, left ventricular end-diastolic diameter, white blood cell count, uric acid, interleukin-1β, C-reactive protein, fibrinogen, CHA2DS2-VASc score, and serum Hcy, D-D levels in thrombus group were higher than those in non-thrombotic group, and left ventricular ejection fraction was lower than that in non-thrombotic group (P<0.05). The results of multivariate analysis showed that CHA2DS2-VASc score (OR=3.177, 95%CI: 1.326-7.613), serum Hcy (OR=2.869, 95%CI: 1.197-6.875), serum D-D (OR= 3.347, 95%CI: 1.397-8.019) were the influencing factors of thromboembolism in NVAF patients (P<0.05). ROC analysis showed that the AUC predicted by the combination of CHA2DS2-VASc score, serum Hcy and D-D was higher than the AUC predicted by the combination of CHA2DS2-VASc score and serum Hcy and D-D in NVAF patients (P<0.05). Conclusion The combination of CHA2DS2-VASc score, and serum Hcy, D-D levels has a high predictive effect on the risk of thromboembolism in patients with NVAF.
