摘　　要：目的通过经胸超声及经食管超声,评估心房颤动患者的左心耳功能,探索其左心耳自发显影(SEC)及左心耳血栓(LAAT)形成的独立危险因素。方法 (1)将受检查者分为三组。记录三组受检者的年龄及超声数据,对三组数据进行均数比较。(2)根据TEE的结果分为SEC和(或)LAAT组和未见异常组,将两组数据进行多因素Logistic回归分析,探索SEC和(或)LAAT的独立危险因素。结果 (1)三组参数中,年龄及代表左心及左心耳内径的参数随着对照组、A、B组的趋势逐渐增大,代表左心及左心耳功能的参数则逐渐减小。(2)多因素Logistic回归分析显示LAAEF和LAA-PFV为SEC和(或)LAAT的独立危险因素(P<0.05)。结论经食管超声在评估左心耳功能及诊断左心耳血栓方面可提供敏感指标,其中LAAEF、LAA-PFV是SEC和(或)LAAT形成的最强独立预测因素。Objective The study evaluated the function of the LAA and made the exploration of the independent risk factors about SEC and/or LAAT by TTE and TEE with TDI of the patients with AF.Methods（1）The patients were divided into three group,the control group,the paroxysmal AF group（Group A）,persistent AF group（Group B）.The age and other dates were recorded,then comparing the difference of these three datas.（2）The TEE for the diagnosis of AF patients would be divided into Group SEC and/or LAAT Patients and Group normal,the differences of these two sets were stratified,the multivariate Logistic Regression Analysis was uesd to explore the independent risk factors.Results（1）Three sets of parameters representing parameters of LA and LAA function with the control group,Group A,Group B gradually decreased,as the following the size of the LA and LAA increased.（2）Logistic regression analysis showed that LAAEF and LAA-PFV were the independent risk factors of the SEC and/or LAAT（P〈0.05）.Conclusions Echocardiography could provide a sensitive indicator for the assessment of LAA function and thrombus.LAAEF and LAA-PFV were the strongest independent predictors of the SEC and/or LAAT.
