【摘要】：目的探讨超声二维斑点追踪成像技术对心衰患者左心功能的评价效果。方法选取心力衰竭患者39例(观察组)和查体健康者43例(对照组),两组均接受常规超声心动图检查,并采用GE Echo PAC超声工作站内的二维应变分析软件进行脱机分析。测量并记录两组常规超声心动图参数左心房内径(LAD)、左心室舒张末内径(LVDd)、左心室收缩末内径(LVDs)、左室射血分数(LVEF)以及二维应变参数左心室短轴缩短率(LVFS)、左心室长轴整体收缩期最大峰值应变(GLS)、左心室轴向整体收缩期最大峰值应变(GCS)、左心室整体扭转度(ROT)、心脏整体收缩期应变率(GSRs)、舒张早期应变率(GSRe)、舒张晚期应变率(GSRa)。采用Pearson相关分析各参数之间的相关性。结果与对照组比较,观察组LAD、LVDd、LVDs、LVEF、LVFS GLS、GCS、GSRs、ROT、GSRe、GSRa差异均有统计学意义(P均0.05)。观察组GLS、GCS与LVEF呈负相关(r分别为-0.849、-0.732,P均0.01),ROT与LVEF呈正相关(r=0.786,P0.01)。结论超声二维斑点追踪成像能反映心力衰竭患者左心功能的变化,对患者左心功能的评估有重要价值。
[Abstract]:Objective to evaluate the left ventricular function in patients with heart failure by two-dimensional ultrasonic speckle-tracing imaging.Methods 39 patients with heart failure (observation group) and 43 healthy persons (control group) were examined by routine echocardiography, and the two dimensional strain analysis software of GE Echo PAC workstation was used for offline analysis.The parameters of conventional echocardiography, left atrial diameter, left ventricular end-diastolic diameter, left ventricular end-systolic diameter, left ventricular ejection fraction (LVEF), left ventricular short axis shortening rate and left ventricular long axis shortening rate were measured and recorded.The maximal peak strain in volume systolic period was GLSN, the maximal peak strain in axial global systolic phase of left ventricle was GCSA, the global torsion degree of left ventricle was ROT, the global systolic strain rate of heart was GSRs1, the strain rate of early diastolic strain was GSReN, and the late diastolic strain rate was GSRA.The correlation of parameters was analyzed by Pearson correlation.Results compared with the control group, there were significant differences in LVDslVEFV, LVFS, GSRS, GSRS, GSReN, GSRa and GSRA between the two groups (P < 0.05).In the observation group, there was a negative correlation between GCS and LVEF (r = -0.849) and -0.732n (P < 0.01), respectively. There was a positive correlation between GCS and LVEF (r = 0.786, P = 0.01).Conclusion Ultrasound two-dimensional speckle tracing imaging can reflect the changes of left ventricular function in patients with heart failure and has important value in evaluating left ventricular function.
