【摘要】：目的:探討斑點(diǎn)追蹤技術(shù)對心衰患者預(yù)后的預(yù)測價(jià)值。方法:選取心力衰竭患者86例,根據(jù)治療3個(gè)月后左心室射血分?jǐn)?shù)(LVEF)是否大于50%,分為恢復(fù)組(A組,56例)和未恢復(fù)組(B組,30例)。比較患者病程初診時(shí)、3個(gè)月后常規(guī)二維超聲心動(dòng)圖參數(shù)的差別,兩組患者初診時(shí)斑點(diǎn)追蹤參數(shù)的差別,分別計(jì)算初診時(shí)心底部、心尖部及左心室整體斑點(diǎn)追蹤參數(shù)與治療3個(gè)月后常規(guī)二維超聲心動(dòng)圖參數(shù)LVEF的相關(guān)性。結(jié)果:治療三個(gè)月后LVEF、SV、CO、E/A值高于初診時(shí)(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(shí)(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(jì)學(xué)意義(P0.05)�；謴�(fù)組心尖部旋轉(zhuǎn)角度峰值、旋轉(zhuǎn)達(dá)峰時(shí)間、旋轉(zhuǎn)速度正向峰值、旋轉(zhuǎn)速度負(fù)向峰值以及整體旋轉(zhuǎn)角度峰值、旋轉(zhuǎn)速度正向峰值、旋轉(zhuǎn)速度負(fù)向峰值大于未恢復(fù)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(jì)學(xué)意義(P0.05)。LVEF與心尖部旋轉(zhuǎn)角度峰值、旋轉(zhuǎn)達(dá)峰時(shí)間、旋轉(zhuǎn)速度正向峰值、旋轉(zhuǎn)速度負(fù)向峰值以及整體旋轉(zhuǎn)角度峰值呈正相關(guān)(P0.05)。結(jié)論:斑點(diǎn)追蹤技術(shù)參數(shù)對心衰患者的預(yù)后具有預(yù)測價(jià)值,其中以心尖部參數(shù)的預(yù)測價(jià)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，
