    BackgroundThe CHA2DS2-VASc score has been shown to predict systemic thromboembolism and mortality in certain groups in sinus rhythm (SR), similar to its predictive value with atrial fibrillation (AF).ObjectivesTo compare factors of inflammation, thrombosis, platelet reactivity, and turnover in patients with high versus low CHA2DS2-VASc score in SR.MethodsWe enrolled consecutive patients in SR and no history of AF. Blood samples were collected for neutrophil-to-lymphocyte ratio (NLR), C-reactive protein (CRP), immature platelet fraction (IPF%) and count (IPC), CD40 ligand, soluble P-selectin (sP-selectin) and E-selectin. IPF was measured by autoanalyzer and the other factors by ELISA.ResultsThe study comprised 108 patients (age 58 ± 18 years, 63 women (58%), 28 (26%) with diabetes), In addition, 52 had high CHA2DS2-VASc score (³ 2 for male and ³ 3 for female) and 56 had low score. Patients with low scores were younger, with fewer co-morbidities, and smaller left atrial size. sP-selectin was higher in the high CHA2DS2-VASc group (45, interquartile ratio [IQR] 36-49) vs. 37 (IQR 28-46) ng/ml, P = 0.041]. Inflammatory markers were also elevated, CRP 3.1 mg/L (IQR 1.7-9.3) vs. 1.6 (IQR 0.78-5.4), P < 0.001; NLR 2.7 (IQR 2.1-3.8) vs. 2.1 (IQR 1.6-2.5), P = 0.001, respectively. There was no difference in E-selectin, CD40 ligand, IPC, or IPF% between the groups.ConclusionsPatients in SR with high CHA2DS2-VASc score have higher inflammatory markers and sP-selectin. These findings may explain the higher rate of adverse cardiovascular events associated with elevated CHA2DS2-VASc score.
