摘　　要：目的研究组织多普勒超声左房自发显影阳性的房颤患者血栓形成的危险性。方法对47例心房颤动(AF)患者进行二维超声和多普勒组织成像(DTI)检查,观察左房(LA)自发显影(SEC)情况,根据自发显影结果将患者分为4组(G1-G4),同时对各组患者进行血纤维蛋白原(Fib)、D-二聚体(D-Dimer)化验检查,并以之作为患者血栓形成危险性的指标,比较各组生化指标的差异,对比研究组织多普勒超声左房自发显影的房颤患者血栓形成的危险性。结果各组间Fib及D-Dimer水平差别显著(P<0.05),各组Fib及D-Dimer水平两两比较差别显著(P<0.05),组织超声自发显影阳性组生化指标水平高于阴性组,低于二维超声自发显影阳性组及血栓形成组。结论组织超声SEC较传统的SEC诊断方法更加敏感,能更早预测血栓的形成。Objective To compare the methods of common style echocardiography and doppler tissue imaging （DTI）for diagnosis of left atrial （LA） spontaneous echo contrast （SEC） among atrial fibrillation（AF） patients. Methods Presence of left atrial spontaneous echo contrast in 47 patients of AF in style of common style echocardiography and doppler tissue imaging were observed. On the base of their presence of echocardiography, the patients were divided into four groups（ G1-G4 ） and the difference of Fib and D-dimer level among them were compared. Results The difference between Fib and D-dimer level was significant among four groups （P 〈 0. 05 ）. The difference of Fib and D-dimer level between each two groups was significant （P 〈 0. 05 ）. The Fib and D-dimer level in G2 was higher than that in G1, but was lower than that in G3 and G4. Conclusion The presence of left atrial SEC in manner of DTI is more sensitive than common SEC and can preview thrombus formation earlier.
