摘 要: | 为了评估定量组织速度成像(QTVI)在评价大量饮酒后心肌损害左室功能改变方面的价值,我们对饮酒量符合酒精性心肌病诊断标准患者21例(B组,每日饮白酒≥150g或啤酒4瓶,每周6天~7天,10年以上),30例健康志愿者(A组,正常对照组)进行常规超声参数及QTVI参数测定,包括:二尖瓣环收缩期峰值速度(Vs)、舒张早期运动速度(Ve)、舒张晚期运动速度(Va)等。结果显示,B组常规各超声参数与A组比较差异有显著性统计学意义(P0.01)。QTVI参数与A组比较Va减低(P0.05),Vs、Ve、Ve/Va显著减低(P0.01)。提示QTVI技术能够有效地评估酒精性心肌损害病左室功能的改变。

Abstract: | To evaluate heavy drinking--induced myocardial damage in left ventricular function by quantitative tissue velocity imaging (QTVI), 21 chronic alcohol abusers were included into group B (more than 150 g ethanol or 4 bottles of beer daily for 10 years or more,6 to 7 days per week, n=211 ,and group A (the control group, n=30). The parameters of the conventional echocardiographic and QTVI were respectively measured, including: systolic peak velocity (Vs), diastolic early velocity (Ve), diastolic late velocity (Va). The results is that the conventional echocardiographic parameters showed significant difference between groups A and B (P〈0.01). Va in group B reduced significantly compared with those in groups A (P〈0.05) ,Vs, Ve and Ve/Va in group B reduced significantly compared with those in groups A (P〈0.01). Therefore, QTVI can effectively assess alcohol--induced myocardial damage in left ventricular function. |
