摘　　要：目的分析不同左房内径(LAD)心房颤动患者心脏结构的差异。方法选取2020年1月至2021年11月新疆维吾尔自治区中医医院行射频消融术的108例患者,使用心脏多普勒超声测定LAD,按照LAD大小分为Ⅰ组(<38 mm)、Ⅱ组LAD(38~40 mm)、Ⅲ组(>40 mm)。比较三组每分钟心输出量(CO)、心脏射血分数(EF)、二尖瓣口舒张早期血流速度峰值/二尖瓣环舒张早期运动速度峰值(E/e’)、E、室间隔和游离壁e’及舒张功能不全占比;比较三组舒张末期左心室内径(LVEDD)、收缩末期左心室内径(LVESD)及心室结构异常占比。结果三组E/e’、室间隔侧e’、游离壁e’、舒张功能不全占比比较,差异无统计学意义(P>0.05)。三组EF、CO比较,差异有统计学意义(P<0.05);Ⅲ组EF低于Ⅰ、Ⅱ组,CO高于Ⅰ组,差异有统计学意义(P<0.05)。三组LVEDD、LVESD、心室结构异常占比比较,差异有统计学意义(P<0.05)。Ⅲ组LVEDD、LVESD、心室结构异常占比高于Ⅰ组,Ⅲ组LVESD、心室结构异常占比高于Ⅱ组,Ⅱ组心室结构异常占比高于Ⅰ组,差异有统计学意义(P<0.05)。结论不同LAD患者EF、CO、LVEDD、LVESD、心室结构异常占比有差异,可为房颤患者的治疗方案提供指导意见。Objective To analyze the difference of cardiac structure in atrial fibrillation patients with different left atrial diameter(LAD).Methods From January 2020 to November 2021,108 patients with atrial fibrillation who underwent radiofrency ablation in Xinjiang Uygur Autonomous Region Hospital of Traditional Chinese Medicine were selected.The LAD was measured by cardiac Doppler ultrasound and divided into group Ⅰ(<38 mm),group Ⅱ(38-40 mm),and group Ⅲ(>40 mm)according to the size of LAD.Cardiac output(CO)per minute,cardiac ejection fraction(EF),peak mitral orifice early diastolic flow velocity/peak mitral annulus early diastolic movement velocity(E/e’),E,septum and free wall e’,and the proportion of diastolic dysfunction were compared among three groups;left ventricular end diastolic diameter(LVEDD),left ventricular end systolic diameter(LVESD),and the proportion of ventricular structural abnormalities were compared among three groups.Results There were no significant differences in E/e’,septum e’,free wall e’,and the proportion of diastolic dysfunction among three groups(P>0.05).There were significant differences in EF and CO among three groups(P<0.05).EF in group Ⅲ was lower than that in groups Ⅰ and Ⅱ,CO was higher than that in group Ⅰ,and the differences were statistically significant(P<0.05).There were significant differences in LVEDD,LVESD,and the proportion of ventricular structural abnormalities among three groups(P<0.05).LVEDD,LVESD and the proportion of ventricular structural abnormalities in group Ⅲ was higher than that in group Ⅰ,LVESD and the proportion of ventricular structural abnormalities in group Ⅲ was higher than that in group Ⅱ,and the proportion of ventricular structural abnormalities in group Ⅱ was higher than that in group Ⅰ,and the differences were statistically significant(P<0.05).Conclusion EF,CO,LVEDD,LVESD,and the proportion of ventricular structural abnormalities in different LAD patients are different,which can provide guidance for the treatment of AF p
