【摘要】：目的:探讨斑点追踪技术对心衰患者预后的预测价值。方法:选取心力衰竭患者86例,根据治疗3个月后左心室射血分数(LVEF)是否大于50%,分为恢复组(A组,56例)和未恢复组(B组,30例)。比较患者病程初诊时、3个月后常规二维超声心动图参数的差别,两组患者初诊时斑点追踪参数的差别,分别计算初诊时心底部、心尖部及左心室整体斑点追踪参数与治疗3个月后常规二维超声心动图参数LVEF的相关性。结果:治疗三个月后LVEF、SV、CO、E/A值高于初诊时(58.56%±4.18%vs 45.16%±3.35%;79.68±3.01ml/beat vs 65.70±3.10ml/beat;4.06±0.22L/min vs 3.10±0.21L/min;1.00±0.09 vs0.65±0.07),而LVDd、LVDs值则低于初诊时(52.10±5.51mm vs 58.77±6.27mm;30.00±2.43mm vs 34.23±2.81mm),差异具有统计学意义(P0.05)。恢复组心尖部旋转角度峰值、旋转达峰时间、旋转速度正向峰值、旋转速度负向峰值以及整体旋转角度峰值、旋转速度正向峰值、旋转速度负向峰值大于未恢复组(6.38±1.21 vs 5.43±1.32;84.17%±7.17%vs 70.98%±6.32%;76.55±6.80/s vs 62.18±4.91/s;-45.04±3.28/s vs-53.29±3.20/s;17.56±2.14 vs 6.67±0.86;115.48±8.10/s vs 99.98±6.02/s;-77.83±5.29/s vs-83.48±7.17/s),差异具有统计学意义(P0.05)。LVEF与心尖部旋转角度峰值、旋转达峰时间、旋转速度正向峰值、旋转速度负向峰值以及整体旋转角度峰值呈正相关(P0.05)。结论:斑点追踪技术参数对心衰患者的预后具有预测价值,其中以心尖部参数的预测价值更加明显。
[Abstract]:Objective: to evaluate the prognostic value of dot-tracing technique in patients with heart failure.Methods: 86 patients with heart failure were divided into group A (n = 56) and group B (n = 30) according to whether the left ventricular ejection fraction (LVEF) was more than 50 months after treatment.The parameters of routine two-dimensional echocardiography were compared during the first visit and 3 months later. The parameters of spot tracing in the first visit of the two groups were compared, and the part of the bottom of the heart at the first visit was calculated, respectively.The correlation between the global speckle tracing parameters of the apex and left ventricle and LVEF after 3 months treatment.缁撴灉:娌荤枟涓変釜鏈堝悗LVEF,SV,CO,E/A鍊奸珮浜庡垵璇婃椂(58.56%卤4.18%vs 45.16%卤3.35%;79.68卤3.01ml/beat vs 65.70卤3.10ml/beat;4.06卤0.22L/min vs 3.10卤0.21L/min;1.00卤0.09 vs0.65卤0.07),鑰孡VDd,LVDs鍊煎垯浣庝簬鍒濊瘖鏃，
