【摘要】：目的应用二维斑点追踪成像(2D-STE)技术评价无症状饮酒者随着饮酒时间因素改变对左心房功能的影响。方法选取30例体检健康不饮酒男性作为A组(对照组)。92例男性饮酒者根据饮酒时间长短分为3组:B组(轻度组)、C组(中度组)、D组(重度组)。2D-STE测量左心房最大容积(LAVmax)、最小容积(LAVmin)、左心房收缩前容积(LAVp)、左心房被动射血分数(LAPEF)、左心房主动射血分数(LAAEF)、心室收缩期左心房整体应变率(SRs)、心室舒张早期左心房整体应变率(SRe)及心室舒张晚期左心房整体应变率(SRa)。结果 B组所有指标与A组比较无统计学意义(均P0.05)。C组LAVmin、LAVmax、LAVp、LAAEF及SRa与A、B组比较明显增大(均P0.05),LAPEF、SRs及SRe明显减少(均P0.05)。D组LVDd、LVDs、IVSTd、PWd、LAVmin、LAVmax及LAVp与A、B、C组比较明显增大(均P0.05),LVEF、FS、LAPEF、SRs、SRe、LAAEF及SRa明显减少(均P0.05)。结论左心房功能的损害会根据饮酒时间的改变而改变,2D-STE技术能够有效评价无症状饮酒者左心房功能的变化情况。
[Abstract]:Objective to evaluate the effects of drinking time on left atrium function in asymptomatic drinkers using two-dimensional speckle tracking imaging 2D-STE. Methods 30 healthy healthy men were selected as group A (control group, n = 92). The drinkers were divided into 3 groups according to the duration of drinking. (mild group C group (moderate group D) measured left atrial maximum volume of LAVmaxma, minimum volume of LAVmina, left atrial presystolic volume of LAVphe, left atrial passive ejection fraction LAPEFF, left heart. Atrial active ejection fraction (LAAEFG), left atrial global strain rate (SRS), early left atrial strain rate (SReS) and late diastolic left atrial global strain rate (SRA) were not found in group B. results there was no statistical difference between group B and group A. Compared with group A (P 0.05) and group A (P 0.05), the SRS and SRe of group A (P 0.05) were significantly decreased (P < 0.05). Conclusion the impairment of left atrial function in group C and group A were significantly increased compared with that in group A (P 0.05). Conclusion the impairment of left atrial function in group A (P 0.05) may be based on the changes of left atrial function in group A (P0.05) and in group A (P < 0.05), and in group A (P < 0.05), there is no significant difference between group A and group A (P > 0.05). Conclusion the changes of left atrial function in group A (P 0.05) and in group A (P < 0.05) are significant higher than those in group A (P < 0.05). Conclusion the changes of left atrial function in group A (P 0.05) are significantly higher than those in group A (P = 0.05). Conclusion the impairment of left atrial function in group A (P 0.05) may be based on the changes of left atrial function. The change of alcohol time and change of 2D-STE can effectively evaluate the changes of left atrial function in asymptomatic drinkers.
