【摘要】：目的探讨三维斑点追踪成像(3D-STI)技术评价不同程度风湿性二尖瓣狭窄(MS)患者左心室整体收缩功能的价值。方法选取MS患者53例,轻度狭窄21例为病例A组,中度狭窄15例为病例B组,重度狭窄17例为病例C组。另选取43例健康志愿者作为对照组。采用3D-STI技术获取各组左心室整体纵向收缩期峰值应变(GLS)、径向应变(GRS)、圆周应变(GCS)、面积应变(GAS)、左心室射血分数(LVEF),比较各组指标间的差异。结果与对照组相比,A组的GLS降低;与对照组、A组相比,B组的GLS、GAS、GCS及GRS降低;与对照组、A组及B组相比,C组的GLS、GAS、GCS及GRS进一步降低,差异均有统计学意义。LVEF与GLS、GAS、GCS及GRS值呈正相关。结论 3D-STI可以准确、客观地评价左室收缩功能,为临床提供可靠依据。
[Abstract]:Objective to evaluate the global systolic function of left ventricle in patients with rheumatic mitral stenosis (MSV) by three-dimensional speckle tracking imaging (3D-STI). Methods 53 patients with MS and 21 patients with mild stenosis were selected as group A. There were 15 cases of moderate stenosis in group B, 17 patients with severe stenosis were selected as group C and 43 healthy volunteers as control group. The peak longitudinal systolic strain of left ventricle in each group was obtained by 3D-STI technique. The peak strain of left ventricle (GLSN), radial strain of GRSs, circumferential strain of GCSA, area strain of GASA, left ventricle were obtained by 3D-STI technique. Results compared with the control group, the GLS of group A was lower than that of the control group. Compared with control group A, GCS and GRS in group B were lower than those in group A, and GCS and GRS in group C were significantly lower than those in group A and group B. there was a positive correlation between GCS and GRS. Conclusion 3D-STI is accurate. Objective evaluation of left ventricular systolic function provides a reliable basis for clinical practice.
