| 摘 要： | 目的探讨应用双源CT评估心房颤动(AF)患者左心房及左心耳结构及功能改变,分析其与左心耳血栓形成的关系。方法回顾性分析84例AF患者(AF组)及对照组32例的心脏CT资料,以图像后处理软件测量左心房最大、最小容积(LAVmax、LAVmin)及左心耳最大、最小容积(LAAVmax、LAAVmin),计算左心房射血分数(LAEF)及左心耳射血分数(LAAEF)。根据临床症状将AF组患者分为阵发性AF亚组及持续性AF亚组,又根据是否存在左心耳血栓或"血栓前状态"分为AF左心耳血栓阳性亚组及阴性亚组,对左心房及左心耳容积及心功能指标进行统计学分析。结果 AF左心耳血栓两亚组LAVmax、LAVmin、LAAVmax及LAAVmin均明显高于对照组(P均0.05),且AF左心耳阳性亚组LAVmax、LAVmin、LAAVmax及LAAVmin均高于阴性亚组(P均0.01);AF左心耳血栓两亚组LAEF及LAAEF均明显低于对照组(P均0.001),且AF左心耳阳性亚组LAEF及LAAEF均低于阴性亚组(P均0.001)。持续性AF亚组LAEF及LAAEF均明显低于阵发性AF亚组(P均0.01),阵发性AF亚组与持续性AF亚组间LAVmax、LAVmin、LAAVmax及LAAVmin差异均无统计学意义(P均0.05)。持续性AF亚组左心耳血栓及"血栓前状态"发生率明显高于阵发性AF亚组[72.41%(21/29)vs 14.55%(8/55),χ2=113.46,P0.001]。结论当AF患者存在左心耳血栓或"血栓前状态"时,左心房及心耳结构及功能重构更明显。
