摘　　要：目的探讨二维斑点追踪成像技术对心力衰竭患者心脏收缩功能的评价价值。方法选择心力衰竭患者30例作为心力衰竭组,选择同期无心血管疾病的体检者30例作为对照组,2组均予二维斑点追踪成像技术检查,随访心力衰竭组的预后并进行影响因素分析。结果心力衰竭组的LVEF、SRc与SRa明显低于对照组,LVEDD和SRs明显高于对照组(P<0.05)。LVEF、LVEDD、SRs、SRc、SRa均与预后有显著相关性(P<0.05);LVEF、SRc、SRa为影响预后的主要因素(P<0.05)。结论二维斑点追踪成像技术评价心力衰竭患者心脏收缩功能具有快速、准确、无创、客观等优点,能够预测患者预后。Objective To explore the values of 2DSTI in the evaluation of cardiac contractile function in patients with HF.Methods 30 patients with HF diagnosed and treated in our hospital were selected as the heart failure group and 30 subjects without cardiovascular disease during the same period were selected as the control group.Both groups were examined by the two-dimensional speckle tracking imaging technology.The prognosis of the heart failure group was followed up and the influencing factors were analyzed.Results The LVEF,SRc and SRa of the heart failure group were significantly lower,while the LVEDD and SRs were significantly higher than the control group (P<0.05).LVEF,LVEDD,SRs,SRc and SRa were all significantly correlated with prognosis (P<0.05).LVEF,SRc and SRa were the main influencing factors of prognosis (P<0.05).Conclusion The two-dimensional speckle-tracking imaging technology has the advantages of rapid,accurate,non-invasive and objective evaluation of cardiac systolic function in patients with heart failure,and can predict patients’ prognosis.
