摘要:: 目的:研究应变率成像技术在评价酒精性心肌病患者左心房功能改变方面的应用价值。方法:对30例酒精性心肌病患者(ACM组)和相匹配年龄30例正常人(正常对照组)，分别进行左心房常规二维参数及应变率参数测量。常规参数包括：左心房最小容积（LAVmin）、左心房最大容积（LAVmax）、左心房p容积（LAVp）、左心房最大直径（LAMD）、左心房主动射血分数(LAAEF)及左心房被动射血分数(LAPEF)。应变率测量指标包括：左心房间隔、侧壁、下壁及前壁收缩期的应变率（SSR）、舒张早期应变率（ESR）及舒张晚期应变率（ASR）。结果:与正常对照组相比，ACM组常规参数LAMD、LAVmax、LAVmin、LAVp及LAAEF增高，LAPEF减低，差异均具有统计学意义（均P<0.05）。ACM组ASR增高，而SSR及ESR减低，差异具均有统计学意义(均P<001)。结论:应变率成像可以准确评价酒精性心肌病患者左心房功能。

Abstract:: AIM:To explore the value of strain rate imaging (SRI) technology in evaluating left atrial functions in patients with alcoholic cardiomyopathy (ACM). METHODS: Conventional echocardiography and SRI were performed in 60 subjects: 30 with ACM (ACM group) and 30 agematched controls. Conventional parameters included left atrial maximum volume (LAVmax), left atrial preatrial contraction volume (LAVp), left atrial minimum volume (LAVmin), left atrial maximum diameter (LAMD), left atrial active ejection fraction (LAAEF) and left atrial passive ejection fraction (LAPEF). Early diastolic periods of left ventricle (ESR), late diastolic periods of left ventricle (ASR) and contraction period of left ventricle (SSR) were obtained in the basal septal, lateral, inferior and anterior atrial walls from the left atrium by SRI. RESULTS: Compared with those in the control groups, LAMD, LAVmax, LAVmin, LAVp and LAAEF significantly increased (P<005), whereas LAPEF significantly decreased (P<005). ASR increased (P<001) but SSR and ESR decreased (P<001). CONCLISION: SRI is an accurate method to evaluate left atrial functions in patients with ACM.
