【摘要】：目的:探討斑點追蹤技術對心衰患者預后的預測價值。方法:選取心力衰竭患者86例,根據治療3個月后左心室射血分數(LVEF)是否大于50%,分為恢復組(A組,56例)和未恢復組(B組,30例)。比較患者病程初診時、3個月后常規(guī)二維超聲心動圖參數的差別,兩組患者初診時斑點追蹤參數的差別,分別計算初診時心底部、心尖部及左心室整體斑點追蹤參數與治療3個月后常規(guī)二維超聲心動圖參數LVEF的相關性。結果:治療三個月后LVEF、SV、CO、E/A值高于初診時(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值則低于初診時(52.10±5.51mm vs 58.77±6.27mm;30.00±2.43mm vs 34.23±2.81mm),差異具有統(tǒng)計學意義(P0.05)。恢復組心尖部旋轉角度峰值、旋轉達峰時間、旋轉速度正向峰值、旋轉速度負向峰值以及整體旋轉角度峰值、旋轉速度正向峰值、旋轉速度負向峰值大于未恢復組(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),差異具有統(tǒng)計學意義(P0.05)。LVEF與心尖部旋轉角度峰值、旋轉達峰時間、旋轉速度正向峰值、旋轉速度負向峰值以及整體旋轉角度峰值呈正相關(P0.05)。結論:斑點追蹤技術參數對心衰患者的預后具有預測價值,其中以心尖部參數的預測價值更加明顯。
[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.緇撴灉:娌葷枟涓変釜鏈堝悗LVEF,SV,CO,E/A鍊奸珮浜庡垵璇婃椂(58.56%鹵4.18%vs 45.16%鹵3.35%;79.68鹵3.01ml/beat vs 65.70鹵3.10ml/beat;4.06鹵0.22L/min vs 3.10鹵0.21L/min;1.00鹵0.09 vs0.65鹵0.07),鑰孡VDd,LVDs鍊煎垯浣庝簬鍒濊瘖鏃，
