【摘要】：目的分析三维斑点追踪技术评价冠状动脉粥样硬化性心脏病(冠心病)患者左心室重构的价值。方法选取该院心血管内科2015年1月-2016年6月收治的冠心病患者50例作为观察组,以同期该院行体检的健康成年人50例为对照组,采集两组心脏容积数据,进行左心室体积几何学形态重建与对比观察以及心脏功能对比,发现心脏重构的特征。按照ASE的17节段划分法,分析左心室17节段心肌在长轴运动、径向运动及圆周运动上的应变变化。结果两组三维斑点追踪技术整体径向应变(GRS)、整体环向应变(GCS)、整体纵向应变(GLS)及整体面积应变(GAS)各整体心肌应变参数比较,观察组低于对照组,差异有统计学意义(P0.05)。结论三维斑点追踪技术在评价早期冠心病左室功能收缩功能的变化方面具有较高的敏感性,可为临床评价冠心病患者左心室重构提供可靠依据。
[Abstract]:Objective to evaluate the left ventricular remodeling in patients with coronary atherosclerotic heart disease (CHD) by three-dimensional speckle tracing. Methods 50 patients with coronary heart disease (CHD) admitted in our hospital from January 2015 to June 2016 were selected as the observation group and 50 healthy adults who underwent physical examination in the same period as the control group. The cardiac volume data of the two groups were collected. The characteristics of cardiac remodeling were found by observing and contrasting left ventricular volume geometry and heart function. According to the 17 segments division method of ASE, the strain changes of left ventricular 17 segment myocardium on long axis motion, radial motion and circular motion were analyzed. Results the global radial strain (GRS), global circumferential strain (GCS), global longitudinal strain (GLS) and global area strain (gas) of the two groups were compared with those of the control group (P0.05). Conclusion Three-dimensional speckle tracing technique has a high sensitivity in evaluating the changes of left ventricular systolic function in early coronary heart disease and can provide reliable basis for clinical evaluation of left ventricular remodeling in patients with coronary heart disease.
