摘要
目的:应用食管超声心动图(TEE)分析阵发性心房颤动(PAF)患者发生左心耳血栓(LAAT)的危险因素。方法:选取2018年1月—2022年9月梅州市人民医院300例行TEE检查的PAF患者,按是否发生LAAT分为血栓组(n=18)和非血栓组(n=282),比较两组患者的超声数据,并进行多因素Logistic回归分析。结果:300例PAF患者中,LAAT的发生率为6.00%;单因素结果显示,血栓组患者的左心耳口直径(LAA-D)、左心耳深度(LAA-L)、左心耳最大充盈速度(LAA-PFV)和左心耳最大排空速度(LAA-PEV)与非血栓组相比,差异有统计学意义(P<0.05);Logistic分析结果显示,LAA-D、LAA-PEV和LAA-PFV是PAF患者发生LAAT的独立危险因素(OR>1,P<0.05)。结论:TEE在评估PAF患者发生LAAT方面可提供敏感指标,其中LAA-D、LAA-PEV和LAA-PFV是LAAT形成的独立危险因素。
Objective Risk factors for left atrial appendage thrombosis(LAAT)in patients with paroxysmal atrial fibrillation(PAF)were analyzed based on transesophageal echocardiography(TEE).Methods A total of 300 PAF patients who underwent TEE examination in Meizhou People’s Hospital from January 2018 to September 2022 were selected and divided into thrombus group(n=18)and non-thrombus group(n=282)according to whether LAAT occurred.The ultrasound data of the two groups were compared and multivariate logistic regression analysis was performed.Results Among 300 PAF patients,the incidence of LAAT was 6.00%;Univariate results showed that the left atrial appendage diameter(LAA-D),left atrial appendage depth(LAA-L),left atrial appendage maximum filling velocity(LAA-PFV)and left atrial appendage maximum emptying velocity(LAA-PEV)in the thrombus group were significantly different from those in the non-thrombus group(P<0.05).Logistic analysis showed that LAA-D,LAA-PEV and LAA-PFV were independent risk factors for LAAT in PAF patients(OR>1,P<0.05).Conclusions TEE can provide sensitive indicators for evaluating LAAT in PAF patients,and LAA-D,LAA-PEV and LAA-PFV are independent risk factors for LAAT formation.
