Abstract:
Objective To explore the correlation between prethrombotic state (PTS)and chronic atrial fibrillation in elderly patients,and to analyze the risk factors.Methods A total of 142 elderly patients with chronic atrial fibrillation from May 2009 to May 2011 were selected.Patients were divided into the PTS group (n =90) and no-PTS group (n =52) by transesophageal echocardiography (TEE).The left atrial diameter (LAD),left ventricular ejection fraction (LVEF),levels of high-sensitivity c reactive protein (hs-CRP),D-Dimer (D-D),β-platelet globulin (β-TG),B type brain natriuretic peptide (BNP),P-select element (PS),endothelial damage/dysfunction mark (vWF) and platelet aggregation rate-AA (PAR-AA)were determined.The related factors of prethrombotic state in elderly patients with chronic atrial fibrillation were analyzed by the multiple regression analysis.Results There were significant differences in the time of atrial fibrillation,frequency of patients with mitral regurgitation,levels of hs-CRP,D-D,β-TG,BNP,PS,vWF and PAR-AA between the PTS group and the non-PTS group [(6.9±1.8)years vs.(4.7±1.3)years,39 cases (43.3％)vs.11 cases (21.2％),(7.8±1.0)mg/L vs.(2.7±0.4)mg/L,(706.6±38.1)μg/L vs.(270.4±28.5)μg/L,(147.2± 21.3) μg/L vs.(117.7±17.1)μg/L,(1075.4±31.2)ng/L vs.(222.6±26.0)ng/L,(88.5±13.9)μg/Lvs.(37.4±11.2)μg/L,(36.1±11.2) ×10-3U/L vs.(26.4±9.9)×10-3U/L,(27.4±12.6)％ vs.(19.7±5.7)％,t=4.52,11.18,15.31,31.20,4.89,166.46,22.59,14.06,5.45,respectively,all P＜0.01].Multivariate logistic regression analysis showed that the time of chronic atrial fibrillation,mitral regurgitation,levels of hs CRP,PS,vWF and PAR-AA were independent risk factors for PTS in elderly patients with atrial fibrillation (OR=3.57,2.19,2.91,3.28,2.37,1.98,respectively,all P＜0.05).Conclusions The time of atrial fibrillation,mitral regurgitation,levels of hsCRP,PS,vWf and PAR-AA are independent risk factors for PTS in elderly patients with chronic atrial fibrillation.
