| 目的 分析房颤患者血栓形成与左心耳结构功能的关系。方法 采用经食管超声心动图检测88例房颤患者及18例对照组患者的左心腔前后径(LA-D)、左心耳入口宽度(LAA-W)、左心耳长度(LAA-L)、左心耳前壁、后壁及顶部的运动速度及左心耳充盈及排空速度等指标。根据左心耳内透声,将房颤患者分为无自发显影(NO SEC)亚组、自发显影(SEC)亚组、泥浆样改变(sludge)亚组和血栓(thrombosis)亚组,并将各指标与对照组进行比较。结果 与对照组相比,房颤组患者左心耳结构及功能均有不同程度的改变;sludeg亚组及thrombosis亚组的LAA-W均较对照组增大,差异有统计学意义(P均<0.05);血栓亚组的LAA-L较对照组增大,差异有统计学意义(P<0.01);房颤各亚组的LA-D均较对照组扩大(P均<0.05);房颤各亚组的左心耳充盈及排空速度均较对照组降低(P均<0.05),在血栓亚组降低更为明显;除无自发显影亚组外,余各亚组的左心耳各壁运动速度差异均有统计学意义(P均<0.01)。结论 房颤患者左心耳内血栓形成与左心耳的结构以及功能改变密切相关。 |

| Objective To analyze the interrelationship between thhe structure, function of left atrial appendage(LAA) and thrombosis in patients with atrial fibrillation (AF). Methods Eighty-eight patients with AF and 18 controls were examined with with transesophageal echocardiography (TEE) and Doppler tissue imaging (DTI). Left atrium dimension (LA-D), left atrial appendage width (LAA-W), left atrial appendage length (LAA-L), LAA flow filling velocity (LFFV), LAA flow emptying velocity (LFEV), LAA wall systolic wave (LSW), and LAA wall diastolic wave (LDW) were observed and compared with those of the control group. AF patients were divided into No Spontaneousecho contrast (NO SEC) subgroup, SEC subgroup, sludge subgroup and thrombosis subgroup. Results Compared to control group, LAA structure and function changed differently in AF patients. LAA-W enlarged in sludeg and thrombosis subgroups (all P<0.05), LAA-L became longer in Thrombosis subgroup (P<0.01), LA-D of AF were larger but LFEV and LFFV were lower in all subgroups, especially in Thrombosis subgroup (all P<0.05), while statistical significance of moving velocity of LAA wall were found among SEC subgroup, sludge subgroup and thrombus subgroup (all P<0.01). Conclusion Thrombosis in AF is closely related with the changs structure and function of LAA. |
