摘　　要：目的应用经食管超声心动图(TEE)评估非瓣膜性房颤患者(AF)左心耳功能分级及与血栓发生率的关系。方法将1228例阵发性房颤患者(A组)、928例持续性房颤患者(B组)和20例对照组(C组),运用TEE测量三组收缩期左心房内径(LAD)、舒张期左心室内径(LVD)、左室射血分数(LVEF)、左心耳口直径(LAA-D)、左心耳深度(LAAL)、左心耳收缩末期(LAA-ESV)、舒张末期容积(LAA-EDV)、左心耳容积变化率(LAA-VCR)、左心耳最大排空速度(LAA-PEV)。LAA-VCR将A组及B组分为正常、轻、中、重度减低组,并进行比较。结果B组较A组LAA-PEV和LAA-VCR更易减低,同时中重度减低者左心耳血栓发生率显著增高。结论持续性房颤患者左心耳功能中重度减低者高于阵发性房颤,同时附壁血栓发生率也明显增高。Objective Evaluation of left atrial appendage function and its relationship with thrombosis rate in patients with non-valvular atrial fibrillation by transesophageal echocardiography.Methods 1228 patients with paroxysmal atrial fibrillation,928 patients with persistent atrial fibrillation,and 20 normal subjects were divided into groups A,B,and C.Three sets of systolic left atrial inner diameter(LAD)and diastolic left ventricular internal diameter(LVD)were measured by TEE.Left ventricular ejection fraction(LVEF),left atrial appendage diameter(LAA-D),left atrial appendage depth(LAA-L),left atrial appendage End-systolic volume(LAA-ESV),end-diastolic volume(LAA-EDV),left atrial appendage volume change Rate(LAA-VCR),left atrial appendage maximum emptying rate(LAA-PEV).Group A and component B were normal,light,moderate,and severely reduced according to LAA-VCR and compared.Results Group B was more likely to reduce LAA-PEV and LAA-VCR than group A,and the incidence of thrombosis was significantly higher in patients with moderate to severe disease.Conclusions In patients with persistent atrial fibrillation,the severity of left appendage was significantly higher than that of paroxysmal atrial fibrillation,and the incidence of thrombosis was also significantly increased.
